Background technology
While normally operation after boiler startup, the flow of flue gas of discharge is through air preheater, air preheaterAdd heat primary air, Secondary Air, wherein a wind enters into pulverized coal preparation system and takes from the coal pulverizer of pulverized coal preparation systemBand coal dust flows out, and enters into hearth combustion, the heating surface in the high-temperature flue gas heating boiler that burning produces,Flue gas utilizes its waste-heat air preheater after discharging, and so circulation is to maintain boiler combustion and to ensure oneThe temperature of the needs that inferior wind reaches. Boiler is during from cold start, because self does not also produce hot flue gas,Air preheater can not, to a wind heating, therefore arrange separately an oil burning boiler as starting pot conventionallyStove carries out heat supply, or steam air heater (auxiliary vapour header is taken from the vapour source of steam air heater heating) is set, by warmWind device to the heating of wind so that wind is restarted igniting after reaching predetermined leaving air temp. At temperatureUnder low territorial environment, often undercapacity and cause an air temperature not reach firing temperature of steam air heater,Cause starting ignition smoothly; And the igniting of boiler also has difficulties in the time that coal-fired volatile matter is lower, thisTime need to improve the temperature of a wind. In addition, boiler need to be in burner hearth and burner hearth in the time of cold startHeating surface heating, to reduce thermal stress, this heating process is also to be added by a wind that enters burner hearth conventionallyHeat, need to expend a large amount of auxiliary vapour.
Therefore while, needing better technical scheme to start with solution boiler cold-state, be difficult for lighting a fire, need largerThe auxiliary thermal source of capacity and need to expend the technical problems such as a large amount of auxiliary vapour.
