保持沸腾炉正常运行的关键，在于正确控制沸腾层的送风量、风室静压和沸腾层的温度。１ 送风量的控制一般情况下，燃烧直径小于８ｍｍ的煤粒时其风量必须保持１８００ｍ３／（ｍ·ｈ）。风量过小，难以正常沸腾，时间长了有结渣的可能性。风量过大排烟温度升高，排烟热损失增
The key to maintaining the normal operation of the boiling furnace lies in the correct control of the blowing volume of the boiling layer, the static pressure of the plenum and the temperature of the boiling layer. 1 Control of air supply volume Generally, when the coal particles with a diameter less than 8 mm are burned, the air volume must be maintained at 1800m3/(m·h). When the air volume is too small, it is difficult to normally boil, and there is the possibility of slagging for a long time. Excessive airflow increases the temperature of exhaust fumes and the heat loss of exhaust fumes increases
