着火稳定性现今对大容量蒸汽机组的基本要求是: ——增大调节范围,降低最低负荷线; ——燃烧含灰量不断增大的燃料。对此,为了保证固体燃料及时着火和稳定燃烧,常用油助燃。着火的稳定性是煤粉燃烧要求的基本条件。当火焰接近燃烧器口、着火前沿保持在稳定的位置和所有运行条件都尽可能只出现微小的变化时,煤粉火焰是稳定的。 Ignition Stability Today’s basic requirements for high-volume steam turbines are: - Increasing the adjustment range and lowering the minimum load line; - Burning fuel with increasing ash content. In this regard, in order to ensure the timely burning of solid fuel and stable combustion, commonly used oil combustion. The stability of the fire is the basic requirements of coal combustion requirements. The pulverized coal flame is stable when the flame is near the burner port, the fire front is held in a stable position and all operating conditions are as subtle as possible.
