输煤间水雾除尘对锅炉燃烧效率的影响

Influence of water spray in coal unload cabinet on combustion efficiency of boiler

对某燃煤电厂地下卸煤间的测试结果表明 :当燃煤全水分为 11%时 ,即使不采取水雾除尘措施 ,卸煤间内粉尘浓度也可达到国家职业安全卫生标准。结合该电厂实测数据 。

Measurements in underground coal unload cabinet of a coal fired power plant indicate that the dust concentration in the cabinet can meet national labour safty and health standards even without water spray precipitator if the coal contains 11% or more water.According to the measurement data,the influence of water content in coal on combustion efficiency of boiler is estimated using a computer program.
