Research on Clogging Problem and Treatment of Air Preheater after Denitrification of Boiler
Under the background of increasingly strict modern environmental laws and regulations and increasing environmental awareness,the denitration transformation of coal-fired power plants has become an inevitable trend.Selective Catalytic Reduction(SCR)technology has been widely used because of its efficient and economical denitration effect.After the denitration reformation,the blockage of air preheater(hereinafter referred to as air preheater)has become an important problem that affects the normal operation of boiler and the denitration effect.Based on this,the common causes of clogging of boiler air preheater are analyzed,and the treatment strategies of clogging of boiler air preheater after denitrification transformation are discussed in combination with specific cases.
