Technical points for burning charcoal in charcoal making machine carbonization furnace

Charring is one of the most important processes in charcoal production. It is not the most expensive, but it is the most in need of experience. Some people say that the carbonization process is the risk of charcoal production, which is nothing to say. If you control the carbonization, your entire charcoal production process will save a lot of costs and reduce the waste of resources.

Whether you use logs to produce charcoal or wood corner waste to make charcoal, their raw materials are theoretically wood. If the moisture of the wood is too high, it will directly lead to the low carbon content of the charcoal produced, so that it is not good quality charcoal. The charcoal that we say is the most important thing is its charcoal. If the carbon content is low, what kind of charcoal is called, what is the use value? You said that this is not the case. So no matter what method you use and what raw materials to produce charred charcoal, it is best to dry the raw materials. Dry raw materials are one of the first guarantees for the production of good quality charcoal.

During the entire carbonization process, the wood maintains a temperature of about 100 ° C or below in the carbonization equipment, at which the moisture in the wood is evaporated until it reaches zero, and then the burning temperature of the wood is increased to 280 ° C. This step The energy comes from the heat of combustion of some wood absorbed by some carbonization equipment, which is an energy absorption or endothermic reaction.

When the wood is dried and heated to about 280 ° C, a pyrolysis reaction occurs, and the wood begins to decompose into charcoal, water vapor, methanol, acetic acid, and more complex chemicals, mainly composed of hydrogen in the form of tar and non-condensable gases, carbon monoxide, and carbon dioxide. During this process, the air is controlled to be placed in the kiln, where the oxygen is burned by the wood to be carbon dioxide, so nitrogen is still present in the kiln.

The wood continues to burn in the charcoal kiln. This process is called exothermic reaction. As the exothermic reaction continues, the temperature in the kiln is maintained at around 280 °C. Continued combustion will leave a black mass in the charcoal kiln. This is charcoal. The charcoal produced in this way has a low carbonization temperature, and unless a further external heat source is provided, the temperature in the kiln is up to about 400 ° C. The fixed carbon content of the charcoal is about 65%-70%, and the ash is 3-5. %, but there will be very high volatility, the volatiles of different tree species may vary, but generally reach 30%. By further heating, the carbon content of charcoal will increase, and the volatiles will be decomposed. The temperature in the kiln will reach 500 °C, the carbon content of charcoal will rise to 85%, and the volatile content will drop to about 10%. The charcoal yield is about 32% to 35% of the weight of the wood. Therefore, the theoretical yield of charcoal varies with temperature, and the volatile tar content in charcoal is also related to the carbonization temperature.

When charcoal is fired, the lower the carbonization temperature, the more volatile components of the charcoal produced, and the result is an acidic taste when burning charcoal. This is because charcoal contains a large amount of acidic corrosive tar. This kind of charcoal is used as barbecue charcoal to change the taste of the food, and there is a flame when calcined. Good commercial charcoal should be charged at a temperature of about 500 ° C, and charcoal with about 75% carbon fixation.

The output of charcoal is also related to the material of the raw material. The good wood has a higher lignin content due to the hardwood. In theory, the harder the wood is, the more suitable it is to produce charcoal, and the harder the wood produces the higher the output of charcoal. However, in the charcoal kiln, it is not the more dense and dense the wood, because if the wood is too dense, the wood will be easily broken when it is carbonized. This is because the temperature in the kiln rises too fast and the volatile content decreases. The brittleness of charcoal. A temperature of substantially 450 ° C to 500 ° C is the best balance between the firing of charcoal and the retention of the char and the retention of the block.

There are many factors affecting the output of charcoal and the conversion rate of charcoal. Although the charcoal production capacity is too low or the waste of raw materials is caused by many factors, we will try our best to avoid the factors that may cause problems. Usually we can choose some wood with higher hardness as the raw material of charcoal, the wood should be dried as much as possible, and the wood with a diameter of more than 20cm should be opened and then burned, otherwise it is easy to produce carbon residue and waste. The charcoal must be paid attention to the balance of the temperature in the charcoal kiln. The kiln should reach a carbonization temperature of 500 °C, but sometimes it is very difficult. The reason is that the air in the charcoal kiln is irregular, resulting in many raw materials being burnt into charcoal. And some are still making a living. To improve the charring efficiency of charcoal and the quality of charcoal, a well-designed charcoal kiln is very important. A good charcoal kiln is not only airtight, but also has a balanced air flow, which does not appear: "cold spot", and the overall temperature in the kiln can quickly rise to a carbonization temperature of 500 °C.

How to burn a good mechanism to barbecue charcoal

The so-called charcoal burning is to put the wood material into a high-temperature furnace to ignite. After a period of combustion and temperature rise, the fire is turned off to dry-reduced in an anaerobic state, and a black substance, charcoal, is produced through a pyrolysis process. If you want to burn charcoal, you must master the following essentials.

First, the joints around the charcoal kiln should be tight. No air leakage is allowed. If there is a gas leakage in the carbonization furnace, the amount of oxygen entering the furnace cannot be controlled. The fuel bar in the furnace is prone to auto-ignition, and the carbonization temperature rises too fast so that the charcoal that is fired is loose and easily broken. What's more, excessive oxygen will burn some of the fuel bars into a white powder (ash), which will reduce the output of charcoal and increase the cost of finished charcoal. To this end, before we use the mechanism charcoal carbonization furnace to charcoal, we should do a leak check according to the requirements of the manufacturer's technicians. This is a prerequisite.

When carbonized charcoal is actually used in a carbonization furnace, attention should be paid to the change in furnace temperature during the carbonization process.

First of all, we need to understand the rise of the furnace temperature, which is caused by the combustion of combustible gases that are self-igniting or decomposed by the salary bar in the furnace. Secondly, we must grasp the relationship between the temperature rise and the quality of carbon.

Generally speaking, under the condition that the carbonization furnace kiln does not leak, the temperature rises faster, the density of the produced carbon is small, the carbon is brittle, and the crack is much, but the charging time of the salary bar is greatly shortened, that is, it can be improved. The output of a single furnace. The carbon produced is suitable for industrial and agricultural carbon.

If the furnace temperature is controlled during the carbonization process, the temperature of the furnace is slowly increased, the internal structure of the salary bar is balanced, the decomposition is moderate, and the carbonization rate is slow, but the carbon structure is harder than the former, the carbon surface is smooth, the crack is small, and the ratio is large. There is a certain benefit to long-distance transportation of carbon, but the output of a single furnace is reduced. This kind of charcoal is more suitable for the use of charcoal for barbecue and hot pot. The quality of such charcoal is not only good but also economic value. However, its production capacity is not as large as the above, and producers must be aware of this.

In the carbonization process of the carbonization furnace, it is necessary to learn to observe the changes of the flue gas emitted from the chimney of the carbonization furnace.

The change in the color and amount of smoke emerging from the charring furnace reflects the carbonization of the fuel bar in the furnace. Experienced masters learn to look at the power of smoking. According to theory and practice, we have divided the following three stages for the change of smoke color and quantity.

1. Ignition and salary bar further drying stage, that is, the furnace temperature is below 150 °C, the amount of smoke from the furnace chimney is large and black. If a carbonization furnace with a tar cooling device is used, the color of the smoke is lighter than the former. If an environmentally friendly carbonization furnace is used, and a flue gas recovery device designed on the carbonization furnace, the flue gas generated at this time can be recycled.

2. The pre-decomposition stage, that is, the furnace temperature is between 150 °C and 270 °C, the amount of smoke is slightly smaller than the former, and the smoke color is yellowish.

3. In the decomposition stage, the furnace temperature is between 270 °C and 400 °C, the smoke is white, and the amount is gradually reduced and thinned.

If the amount of smoke is scarce, there is almost no color, and the color is blue and bright, which means the end of charring. At this point, you can “close the fire” and release the charcoal after cooling.

As long as we are skilled in mastering the above-mentioned charcoal carbonization technology, it is not difficult to develop good charcoal that meets the requirements of the producer.

The charcoalization of the mechanism charcoal is very important. If the charcoal is not good, it will be abandoned and the charcoal production will fail. But the production of mechanical charcoal, as well as a technology is also very important, that is, rod forming technology. Both are indispensable.

What are the advantages of carbonization in an anthracite carbonization furnace?

The smokeless carbonization furnace is important equipment in the mechanism of charcoal production. The environmental protection production of the equipment has been recognized by people. The carbonization process of the anthracite carbonization furnace is also the core of the mechanism of charcoal production. What advantages does the production of smokeless carbonization furnace have?

The carbonization technology in the carbonization process of an anthracite carbonization furnace is the above-ground part of the building. The carbonization is divided into three stages: low-temperature discharge temperature, high-temperature calcination, and cooling and cooling. The salary bar has about 8% water when it enters the carbonization furnace. This water is the enemy of carbonization. Because the mechanism salary bar is afraid of getting wet, the water will seriously affect the quality of carbonization in the salary bar. Because the time of the tide is essential. Tidal time is essential. The drainage time is generally 10-15 hours for the earthen kiln and 2-3.5 hours for the mechanism kiln. The long heating time can prevent the salary bar from being cracked by moisture and ensure the quality of carbonization. When the furnace temperature rises to 300 degrees, a large amount of combustible gas can be generated in the furnace. Each kilogram of raw material is logically equivalent to produce three cubic methane gas. These gases can be used to heat the furnace. The exhaust heat source for drying more than 400 degrees for the heat preservation calcination stage to seal the oxygen-free closed fire can be taken from spontaneous combustion or water cooling. After the charcoal is discharged from the kiln, it must be ventilated and then charcoal to prevent carbon dioxide poisoning. The charcoal from the kiln should be placed outdoors for more than 8 hours. Prevent resurgence and fire.

The charcoal carbonization furnace equipment utilizes the principle of dry distillation carbonization to decompose and decompose the fuel rod in the furnace to form combustible gas, tar, and charcoal. The utility model adopts a mobile steel plate structure, and the exhaust pipe at the top of the furnace is sequentially connected with the tar separator and the induced draft fan, and has the advantages of unique structure, large effective volume, advanced carbonization process, short cycle, high output, good environmental protection, and long service life. . Our factory can also produce various high, medium and low-temperature charcoal furnaces for customers.

Smokeless charcoal carbonization furnace equipment finished fiber rod is the use of sawdust, crop straw (corn straw, soybean straw, sorghum stalk, cotton stalk, rape stalk, peanut stalk, sunflower stalk), chaff, grass, shrub branches, bamboo and wood The truncated, bamboo chips, bagasse and the like are used as raw materials, and are extruded at a high temperature using a fiber rod device. The product has high density, small volume and good flammability, and can replace fuelwood and coal. The general product has an outer diameter of 50-60mm and a hole diameter of 15-20mm. It has a hollow four-corner or hexagonal column shape. It can also be made into a spherical shape, a granular shape, or a honeycomb shape. This product is especially suitable for heating in the northern part of the country in autumn and winter, heating in greenhouses or fuel for ordinary life.

The above is the advantage of the anthracite carbonization furnace in the charcoal production mechanism charcoal, which can make good use of biomass waste to produce mechanism charcoal, and the smokeless carbonization furnace realizes smokeless environmental protection in production, so the users can use it with confidence. An anthracite carbonization furnace produces charcoal.

Charcoal making machine equipment motor maintenance method

Charcoal making machine equipment is a device that uses biomass waste as raw material to produce charcoal. Users of charcoal making machine equipment can increase the feeding amount to increase the production capacity when operating the charcoal making machine, achieve faster production efficiency, and produce larger Profit, and in the normal operation of the charcoal making machine equipment, usually the motor needs the operator to carry out detailed observation and sensitive hearing to judge the maintenance, and the correct maintenance method is also a lot, then how to make the motor of the charcoal making machine equipment correct? maintain?

1. The temperature of the motor of the charcoal making machine should not exceed the allowable limit during normal operation. The operator of the charcoal briquette machine should always pay attention to monitor the temperature rise of each part during the operation.

2. Monitor the load current of the charcoal briquette machine motor. When the motor fails, the stator current will increase sharply and the motor will overheat. In the case of a large-scale charcoal production line, an ammeter should be installed to monitor the motor load current when using a larger power motor. The load current of the motor of the charcoal making machine should not exceed the current value specified on the nameplate.

3. Pay attention to the smell, vibration, and noise of the motor. The winding will emit an insulating burnt smell due to the high temperature. Some problems with charcoal making machines, especially mechanical failures, quickly react to vibrations and noises, so when you smell the burnt smell or notice abnormal vibration or rubbing, especially large "click" or other noise A power outage should be checked immediately.

4. After checking the bearing heat and oil leakage of the charcoal making machine equipment, regularly change the lubricating oil. Generally, when replacing the lubricating oil, the bearing and the bearing cap are cleaned with kerosene and then washed with gasoline. Rolling bearing grease should not exceed 70% of the bearing chamber volume.

The above is the method of motor maintenance of the charcoal making machine equipment. When the user operates the charcoal making machine equipment to produce charcoal, the maintenance equipment can be maintained according to these, so that it can better operate, improve the production efficiency and effect, and simultaneously produce High-quality charcoal brings better economic benefits to yourself.
