Description

technical field [0001] The invention relates to an online simulation system for a cement decomposition furnace and a method for establishing the same, belonging to the technical field of cement production simulation. Background technique [0002] The calciner is a device that disperses and suspends raw meal powder in the airflow, so that the fuel combustion and calcium carbonate decomposition process can occur within a short time (generally 1.5 to 3 seconds). It is a high-efficiency direct combustion solid-gas phase heat exchange device. [0003] What is carried out in the cement calciner is a process of continuous production and complex and changeable working conditions, which is the core link of cement production. This link mainly completes the tasks of pulverized coal combustion and decomposition of raw meal. In this process, the decomposition of carbonate requires a relatively stable temperature. If the temperature is too high, the preheater will easily cause blockage;...
