<p>PROBLEM TO BE SOLVED: To provide a denitration method capable of simplifying the device and treatment after denitration by executing denitration treatment in the absence of a catalyst and capable of improving gas turbine operation efficiency by lessening pressure drop for low temperature combustion waste gas, especially gas turbine waste gas. SOLUTION: In the denitration method for the combustion waste gas containing nitrogen oxide, the denitration treatment of the waste gas is executed at a specified temperature region in the absence of the catalyst after injecting ammonia or methane to the waste gas. In the denitration system of the waste gas, an injecting means for supplying the ammonia or the methane is provided downstream of a gas turbine discharging waste gas by burning fuel gas, and a denitration device is provided just after the injecting means.</p> |
