Dealing with problems during operation of charcoal machine

1. the rationale why the kiln doesn't turn off: the sole reason for this problem is that the kiln leaking air. Solution: the answer is extremely simple, and repair the leaks in time.

2. Reasons for poor carbon shrinkage or insufficient hardness: There are two main reasons:

a. The carbonization process is just too fast. b. The temperature isn't high enough. Solution:

A. The carbonization process is just too fast: too fast carbonization will inevitably cause cracking of charcoal. Once the charcoal cracks an excessive amount of, it'll be difficult to shrink. cannot be too high. Generally don't exceed 300 degrees.

B. Insufficient temperature for heating: When the temperature of coal smelting is elevated, the temperature doesn't reach the specified temperature. Generally, the charcoal can shrink well only the temperature of charcoal reaches 800 degrees or higher. the upper the temperature of charcoal, the higher the shrinkage. However, the upper the temperature, the lower the speed of charcoal and therefore the higher the value. it's generally recommended to boost the temperature to 800 degrees.

3. Reasons for several carbon cracks: mainly the temperature of the carbonization process is just too high, or it's going to be an inherent defect of the wood chip stick. Solution: If it's not an inherent defect brought by the wood chip stick, then you want to concentrate to control the temperature of the carbonization process, and therefore the temperature of the carbonization process shouldn't exceed 300 degrees. If it's an inherent defect of the wood chip stick, please attend the molding question answer in Chapter 4 to seek out an answer .

4. Reasons for top carbon volatility: the sole reason is that the temperature isn't enough. Solution: Please extend the heating time and lift the temperature above 800 degrees.

5. Exceeding the quality of carbon ash features a great impact on the chemical quality of carbon. Not only can products not be exported, but even domestic sales are affected in severe cases.

Reason: the most reasons are as follows: A, the staple isn't clean, B, the staple features a high ash content, C, the carbonization temperature is high, and therefore the temperature rise time is just too long.

Solution: A. The raw materials aren't clean: On the one hand, the most method to unravel this problem is to regulate the transportation process of the raw materials to make sure that the raw materials aren't polluted during transportation; on the opposite hand, to regulate the storage conditions of the raw materials and check out to avoid wind and sand and soil. Pollution. At an equivalent time, the source of raw materials must be controlled. B. The ash content of the raw materials is high: for instance, the ash content of rice husks, straws, weeds, etc. is comparatively large, therefore the ash content of the charcoal is comparatively large. Generally speaking, the charcoal can't be utilized in barbecues. The industry can only be utilized in industry. C. High carbonization temperature: If the temperature within the carbonization process is just too high, the carbon element will escape with the mixture of hydrogen and oxygen. during this way, the carbon is going to be relatively light, and therefore the ash won't escape, which suggests that the ash content of the carbon Relatively increased. D. Warming up time is just too long: an equivalent as above.

6. Reasons for insufficient carbon heating value: There are many specific reasons, like high ash content, the low carbon content in raw materials, high volatile content, insufficient carbonization, insufficient carbon temperature, etc. Solution: The temperature didn't reach the specified temperature during the carbon refining. Generally, the charcoal can shrink well only the temperature of charcoal reaches 800 degrees or higher. the upper the temperature of charcoal, the higher the shrinkage. However, the upper the temperature, the lower the speed of charcoal and therefore the higher the value . it's generally recommended to boost the temperature to 800 degrees.
