Title:
APPARATUS FOR TREATING EXHAUST GAS OF COMBINED CYCLE POWER PLANT
Document Type and Number:
WIPO Patent Application WO/2021/251630
Kind Code:
A1
Abstract:
An apparatus for treating the exhaust gas of a combined cycle power plant, of the present invention, comprises a spray nozzle, a reducing agent supply unit, and a control unit, wherein the reducing agent supply unit comprises a hydrocarbon-based reducing agent supply part, an ammonia-based reducing agent supply part and a mixer, the mixer has one end connected to the spray nozzle, is positioned between the ammonia-based reducing agent supply part and the spray nozzle and is positioned between the hydrocarbon-based reducing agent supply part and the spray nozzle, a heat exchange part comprises one heat exchange module and another heat exchange module, a denitrification catalyst is positioned between the one heat exchange module and the other heat exchange module, and the control unit performs control so that the reducing agent supply unit supplies a hydrocarbon-based reducing agent and an ammonia-based reducing agent to the spray nozzle at 300-500°C, which is the temperature of nitrogen oxide-containing exhaust gas between a gas turbine and the heat exchange part. According to the present invention, the exhaust gas of a combined cycle power plant can be very effectively treated.
