Numerical Calculation And Strategy On Air Distribution Of Supercritical Boilers

The air distribution of the power station boiler affects the combustion conditions and economy of the boiler, in order to save resources and reduce emissions, this paper established the model of supercritical 350MW coal-fired boiler, used CFD software for numerical calculation. The standard inlet opening under typical load is determined based on the NOx emissions and combustion conditions. The change in the amount of oxygen at the outlet has been calculated when the inlet increases and decreases under different loads. Based on the calculated data, guide the adjustment of the inlet opening of the 350MW boiler during operation.
