摘要
Abstract
To prevent high temperature corrosion of water walls in boiler furnace and reduce NOx emission from a Russian-made 530 MW unit coal fired boiler,the non-symmetrical high speed closing-to-wall air system was designed and applied.Moreover,the corresponding combustion adjusting tests were carried out.The results show that,after the technical transformation and the combustion adjusting tests,the atmosphere close to the water wall was improved obviously,the high temperature corrosion on the water wall was dramatically prevented,the NOx concentration at the SCR reactor inlet can be kept between 150 mg/m3 and 170 mg/m3,and the boiler efficiency can be increased by 0.2％.The operating security,economy and environmental protection performance of the boiler improved obviously.The results have a demonstration function for NOx emission control and prevention of high temperature corrosion on water walls of the wall type opposed firing boilers.关键词
