A method for purifying the gas-air mixture of a gas turbine unit and a waste-heat boiler is considered [1-3]. This work describes the principle of a gas-turbine plant and a waste-heat boiler operation using a catalytic afterburner, with the help of which a more complete process of carbon dioxide and nitrogenous compounds release occurs. Also, as a result of the exhaust gas-air mixture deeper cleaning process, there is a decrease in emissions within the maximum admissible concentrations (MAC), namely, by the amount of nitrogen and carbon oxides [4–7]. That allows to reduce the number of harmful substances, oxides of nitrogenous and carbon compounds, emitted into the environment. A scheme for cleaning a catalytic afterburner using rotary mesh devices, followed by disposal of carbon deposits and soot substances from the cleaning chamber is shown. This makes it possible to perform a stable ion exchange process, reducing the exhaust gases combustion products amount. It is proposed in this article to use mesh devices in the afterburner, treated with active substances by the method of ion implantation, as one of the most promising methods for modifying mesh surfaces. These processes occurring when the gas-air mixture passes through the afterburner, can reduce MAC emissions for various options for utilizing the discharge fuel mixture of a gas turbine unit (GTU) and heat supply to the waste heat boiler.
