我厂现有四台蒸汽锅炉,其中北京锅炉厂生产的 SIP10—13型锅炉原燃烧方式是机械风力抛煤机加手摇翻转炉排,炉内是层状和悬浮的综合燃烧,大颗粒煤落在炉排上作层状燃烧,小粒煤沫被吹入炉膛空间呈悬浮燃烧。由于稍大的颗粒来不及燃尽就被引风视送出烟道排向大气,所以除了飞灰机械不完全燃烧损失较大外,其烟气黑度超标,一般在林格曼2～3级,至于人工拨火和清炉时,烟气黑度就更大,这不仅浪费能源,而且严重污染环境,工厂的职工和附近的居民深受其苦。为此厂里决定对其进行改造以消除烟尘污染。
I plant the existing four steam boilers, which Beijing Boiler Factory production of SIP10-13-type boiler is the original way of burning coal mechanical wind mill plus flip flip grate, the furnace is layered and suspended combustion, large coal particles Fall in the grate for stratified combustion, small coal was blown into the furnace space was suspended combustion. As the larger particles are too late to burn out by the induced draft as the flue gas discharged to the atmosphere, so in addition to the fly ash mechanical incomplete combustion loss, the flue gas blackness exceeded, usually in Ringermann 2 to 3, As far as artificial fire collection and furnace cleaning are concerned, smoke blackness is even greater. This not only wastes energy but also seriously pollutes the environment. The factory workers and nearby residents are greatly affected. As a result, the factory decided to rebuild it to eliminate soot pollution.
