What are the parameters that affect the operation of circulating fluidized bed boilers?

(1) Changes in coal type. It mainly refers to changes in calorific value, ash content, and volatile matter. (2) Influence of feed particle size and moisture. Feed particle size affects combustion and desulfurization efficiency, while moisture affects bed temperature and heat loss. (3) Effect of the excess air coefficient. It affects combustion efficiency. (4) Effect of changes in fluidization wind speed. The fluidization wind speed affects the heat transfer coefficient, material circulation rate, suspended particle concentration, combustion efficiency, and cyclone separator efficiency. (5) Effect of changes in cycle rate. It affects combustion efficiency and the energy consumption of the unit. (6) Effect of bed temperature. It affects combustion efficiency and carbon monoxide emissions. (7) Other influencing factors. The influence of the buried tube heating surface and return material temperature on bed temperature.
