The secondary air duct for W-shaped flame boiler of 300 MW unit in Shaoguan Power Plant has been calculated and analysed by using Fluent numerical simulation and computational software.Through simulation and computation under four operating conditions of the secondary air duct
the causes leading to deviation of air flow rate on the front and back wall have been found
and retrofit scheme of secondary air duct structure being put forward.After retrofitting
the air flow rate on the front and back wall is reasonably distributed
optimizing the combustion performance in the furnace.
