How the calciner works Decomposition furnace is a new type of thermal equipment in which fuel combustion, heat exchange and decomposition reaction are carried out simultaneously; its types and forms are various. The basic principle is: the preheated raw meal, a certain amount of fuel and an appropriate amount of hot gas are fed into the decomposition furnace at the same time, and the raw meal is in a suspended or boiling state in the furnace; below 900 C, the fuel burns without flame.Vacuum heat treatment of high-speed turning tools At the same time, the heat transfer and calcium carbonate decomposition process are completed at a high speed: the burning time of the fuel and the time required for the decomposition of calcium carbonate take about 2 to 4 s, and the decomposition rate of calcium carbonate in the raw meal can reach 85% to 95%. Vacuum heat treatment process of TC11 titanium alloy pipe The temperature of the preheated material is 800~850°C. Solid, liquid or gas fuel can be used in the calciner. In my country, pulverized coal is mainly
