intermittent reheating furnace

The emission characteristic and average emission concentration of sulfur dioxide from discontinuous coal-burning boiler are monitored with two kinds of smart fume analyzer.

针对间歇式加煤锅炉SO2的排放特性和平均排放浓度测试,结合两种常用的智能烟气分析仪,列举定电位电解法在实际测试中的应用情况以及不同测试分析仪器的功能性特点,指出当前在实际测试过程中存在的人为随意性和易出现的测试误差,提出消除和减少误差的相应对策。

In heating process of the intermittent furnace,flue gas temperature,heat exchanging coefficient of exchanger and air preheating temperature changed continually,so we must calculate heat exchanging area regarding the whole heating process as object.

间歇式炉由于在加热过程中烟气温度不断变化 ,换热器换热系数及空气预热温度也不断变化 ,故必须以整个加热过程为计算对象对换热器进行计算。
