Description

Technical Field

[0001] The utility model belongs to the technical field of material spreading boxes, in particular to a material spreading box for a preheater. Background Art

[0002] The exhaust gas at the outlet of the preheater is mainly composed of three parts. The first part is the theoretical flue gas volume generated by the combustion of pulverized coal, which is mainly determined by the heat consumption of clinker burning. The higher the coal consumption, the greater the calorific value, and the greater the theoretical flue gas volume generated by combustion. The second part is the amount of CO2 produced by the decomposition of raw materials. The third part is the amount of excess air, which is mainly related to the air leakage of the system and the operating air. If the operating air is reasonable, the system is well sealed and leak-proof, and there is little air leakage, then the excess air volume must be very small. The heat taken away by the exhaust gas at the outlet of the preheater is mainly determined by the air volume and air temperature at the outlet of the C1 cylinder. The less the outlet exhaust gas volume and the lower the temperature, the less heat loss will be caused.
