Pulverized coal boiler

Fluidized Bed Boilers Introduction, fuel adaptability. It can burn high-quality coal, can burn a variety of low-grade fuel. Heat

 Fluidized Bed Boilers Introduction   Fluidized Bed Boilers with fluidized bed combustion boiler referred the 1980s developed a new type of combustion equipment, fuel adaptability of this boiler capable of burning with low calorific value of 1000 to 7000 kcal / kg (coal about 4187 ~ 29308KJ/kg) of low volatile fuel, not only good coal available, and especially other boiler can not burn discarded gangue, oil shale, the net calorific value of only 1000 kcal / kg (4187KJ about the coal / kg) can fire normal and stable combustion in a fluidized bed furnace, this boiler energy shortages and rising fuel prices today, has a very prominent reality and social significance.   Boiling boiler has the following advantages:   1, fuel adaptability. It can burn high-quality coal, can burn a variety of low-grade fuel. Heat value in 6281 ~ 10468kJ/kg (1500 ~ 2500cal/kg) oil shale, coal, coal gangue, bituminous and anthracite blended layer burning boiler slag unburned.   2, the furnace unit sectional heat load is high, high heat transfer coefficient of the bed, the combustion efficiency is high (up to 90 ~ 95%).   3, fuel pre-broken into 8mm particles continuously fed into the fluidized bed coal feeder, adjustable speed, constantly churning strongly burning coal particles by high pressure air. Fuel long residence time in the furnace, burning full, so it is suitable for burning a variety of low-value fuel.   4 (850 ~ 950 °C), lower combustion temperature in the combustion process to control the production and emission of NOx and SOx, is a "clean combustion technology.   5, a wide range of load regulation, good regulating performance.   6, ash softening is not easy or bonded, to facilitate the comprehensive utilization.
