Abstract: Abstract:The working principle of denitration system was introduced. The influences of the denitration system on the boiler equipments and the dust collection efficiency of the electrostatic precipitator were analyzed. The feasibility of using SCR denitration technology to improve efficiency of electrostatic precipitator was discussed. In operation of SCR dnitration system, the escaped NH3 and SO2 and the SO3 formed in catalytic conversion are useful for reducing the specific resistance of the dust and improve the adhesiveness of the dust, which are useful for improving the efficiency of electrostatic precipitator theoretically.
