Numerical simulation of Ramin's combustion chamber to investigate the factors affecting the production of carbon monoxide and nitrogen oxide

The boiler is one of the most vulnerable parts of a power plant, which is responsible for producing steam for moving turbines.  In order to increase the thermal efficiency of the power plant, it is necessary to prevent heat loss in the boiler combustion chamber and simultaneously control the environmental pollutant parameters such as NOx and CO.  Failure to control environmental pollutants will increase fuel consumption, rupture of water and wastewater, and, as a result, an unplugged unit of the plant, which will cause a lot of economic damage to power plants and the environment.  Therefore, in this research, it has been tried to study the environmental parameters of the combustion chamber output and its effect on the shape of the flame and the heat output of the boiler as well as the amount of CO and Nox contaminants due to changes in the conditions of operation (Applying  The excess air to the furnace - the change in the inlet air flow - the change in the outlet air flow - is measured and monitored.  The results of this work are that by controlling the oxygen level, adjusting the fuel paths to the burner, the flow rate in the fuel paths, measuring and controlling the initial air flow and blower air, accurate control of the air to fuel ratio, mechanical oscillation of the burners and damper,  The quality of the fuel consumed is estimated by the amount of pollutant production and effective planning to reduce the production of NOx and CO pollutants.
