The mechanism charcoal machine firing mechanism The charcoal process is in full contact with the heat, and the calorific value is much higher. We can accurately measure it through the high-temperature temperature measuring instrument.
1. Drying of raw materials:
To ensure the quality of charcoal, we must make a good mechanism for carbon rods. The excellent removal of carbon rods depends on the equipment, process, but also depends on the amount of moisture in the raw materials. It is generally required that the moisture content of the raw material is less than 10%. Therefore, our first step is to dry raw materials. When we dry raw materials, we can first dry raw materials with large water content in the open air drying or drying for 1-2 days so that the surface water can evaporate to reduce the heat drying. Time and fuel consumption. Then, we put the qualified raw materials into a hot air dryer and dry them to a dry material with a moisture content of less than 10%. The drying temperature is generally about 140°C to 300°C.
2, sticks
Raw material sticks are made in the stick maker. The heating rod is formed outside the forming sleeve of the rod maker, which can increase the temperature of the forming sleeve to about 350°C. In order to ensure that the surface of the rod is smooth, dense, and free of cracks, we can choose the right molding temperature based on the type of raw material and the moisture content. Its level must be field tested to determine. Generally speaking, our screw propeller is qualified, and the raw material moisture content is between 6 and 10%. Drying temperature: varies according to the shape of the material and the heater type, generally between 140°C and 500°C; : The length of the drying pipeline can be adjusted and the air volume distribution can be used to control the temperature of the material, generally not exceeding 55°C to 70°C.
3, carbonization (coal burning)
Low-temperature carbon charring process. During the drying stage, from the start of ignition until the temperature of the furnace rises to 160°C, the moisture contained in the mechanism rod relies on the amount of external heating and the heat generated by the combustion itself to evaporate. The chemical composition of the mechanism rod has hardly changed.
