In order to improve the peak regulation and new energy consumption ability of the power grid

the depth peak regulation carried out by coal-fired power plants has become an inevitable trend. In this study

a 600 MW supercritical concurrent boiler is taken as an example. Through the steady combustion analysis of the burner structure

the balance adjustments of air and pulverized coal

and the analysis of the hydrodynamic characteristics

combined with the security constraints on key combustion parameters of the combustion process in a deep peak load regulation furnace

the boiler achieves the expected target of peak regulation to 20% of the rated load under non-combustion modes

which provides a reference for the same type boiler of depth peak regulation.
