摘要
Using selective catalytic reduction (SCR) denitrification reactors in boiler can affect air preheater working characteristic.This article analyses the influence of air preheater with a SCR denitration reactors operation through thermal equilibrium calculation in different working condition.It is showed that after installating SCR denitrification reactor in boiler, which can make the flue tail air preheater happen ammonium sulfate and acid hydrogen ammonia of condensate and deposition and make the air preheater happen corrosion, jam and heat transfer function reduces.It is necessary for considering antisepsis to the air preheater modification with SCR denitration reactors, another influnce is pulverized coal drying in pulverizing system and pulverized coal combustion in furnace, because of the air temperature reducing out the air preheater.
