高温腐蚀锅炉水冷壁还原性气氛多组分同步测试试验
Experiment on Multi-Component Synchronous Test of Reducing Atmosphere Adjacent to Water Wall of High Temperature Corrosion Boiler
摘要
Abstract
In order to reveal the correlation between H2S concentration and the concentration of CO,H2 and other reducing atmosphere near the water wall of the boiler,a multi-component synchronous test of reducing atmosphere adjacent to water wall was carried out on a 300 MW high temperature corrosion boiler.It is found that when CO volume fraction is between 3.5%and 13%,there is a strong positive correlation between CO concentration and H2S,H2 concentration.The correlation is negative between CO concentration and CO2 concentration.In addition,the positive correlation between CO concentration and H2S concentration is related to the location of the measuring point.With the increase of furnace height,the positive correlation between the two gradually decreases.In the reducing atmosphere,in addition to CO,a large amount of H2 is also observed,with the maximum H2 volume fraction of 4.7%.There is also a strong positive correlation between H2S concentration and H2 concentration.Finally,according to the results of synchronous test,the correlation equations between CO concentration and H2S,H2 concentration were given respectively,which could be used as a reference for operators.关键词
