The adaptability of coal pulverizing systems when the fired coal changed was comparatively analyzed.On this basis
the improvement ways and technical measures were put forward for each pulverizing system
when the high-volatile coal is burned or co-fired.The intermediate coal pulverizing system with hot air blowing has poor adaptability to high-volatile coal and mix coals.For this type of boilers
when highvolatile coal is used
the hot primary air heater should be added to decrease the primary air/fuel temperature.Compared with the cold air blending technology
this hot primary air heater scheme has obvious energy saving effect.
