Locomotive steering mechanism charcoal charcoal production technology comprehensive analysis

Locomotive steering mechanism charcoal charcoal production technologies now on Tanji do a comprehensive analysis of the technical aspects of charcoal has become a hot topic, a lot of people want to know about the whole process of charcoal, so here we come to introduce the next . Burning charcoal whole process of dealing with the heat. How many calories, we can be measured by specific "temperature" Here we have the raw material, molding, carbonization, finished to analyze what is the relationship between carbon and temperature. First, the mechanism charcoal technology - material is dried: We want to ensure the quality of carbon, carbon rods have to do. In addition to great good or bad depends on the equipment, technology, should also depend on the size of the water contained in the raw material. General requirements for raw materials, moisture content less than 12%, but also more than 6%. Therefore, we first step is to dry feedstock. When we first dry feedstock moisture content of the raw material in large open-air drying yard in dry or sun for 1-2 days, allowed surface moisture evaporation, to reduce heat drying time and fuel consumption. We will then feed into the granularity qualified in dry hot air dryer to a moisture content less than 12% of the dry material, drying temperature is generally about 160 ℃ -250 ℃. Second, the mechanism charcoal technology - rods raw rods is done in charcoal machine (or system of rods) inside. Outside tube forming machine has three heating coil, which enables the temperature rises to about forming drum 350 ℃. To ensure the density of carbon stipends of large, smooth surface, no obvious cracks. We can according to the type and moisture content of the raw materials used to select the appropriate molding temperature. Its field-tested to determine the level of talent. Generally speaking, if we assume that the propeller is qualified, and raw material moisture content between 6-12%, then we may be forming a final temperature of sawdust, wood sawdust, wood shavings and bamboo raw materials control in 260-320 between ℃. Third, the charcoal technology - carbonized material was formed if we end product is carbon, then we should stipends by carbonization furnace or kiln firing (or calcining) a qualified carbon. Low-temperature carbonization process of carbon generally be divided into three temperature ranges. 1, the drying phase starting from the ignition to the furnace temperature rose to 160 ℃, the moisture contained in the case stipends rely mainly on external heat and heat generated by the combustion itself stipends were evaporated. Chemical composition stipends almost unchanged. 2, charring the initial stage of this phase depends mainly on the stipends own combustion heat, the furnace temperature rises to between 160-2800C. In this case, wood thermal decomposition reaction, the composition began to change. Wherein the composition is unstable, such as hemicellulose decomposed CO2, CO, and a small amount of acetic acid and other substances. 3, a comprehensive carbonization temperature of this phase 280-400 ℃, at this stage, the woody material is thermally decomposed rapidly, generating a large amount of liquid product acetic acid, methanol and wood tar. It also produces methane, ethylene and other flammable gases, flammable gases in the combustion of these. Thermal decomposition and combustion gases generated a lot of heat, so that the furnace temperature rises. Wood materials under high temperature carbonization into carbon. To calcination temperature charcoal, in addition to the above three stages, we have to increase the heat, the temperature of the furnace continues to rise to more than 700 ℃. Thus, we can release any remaining volatiles in charcoal, charcoal increase the amount of carbon-containing carbon graphite structure so that an increase in conductivity is enhanced. From the above, we are in charcoal technique - charcoal Throughout this process, all the time not to deal with the heat, that is to say, we have to consume some energy to improve carbon economic value and use value.
