Abstract

Numerical simulation of hot flow field in the furnace of a supercharged boiler is conducted with FLUENT software. Velocity field, temperature field and composition concentration field are obtained in the furnace with single burner on front wall and with double burners on front & back wall, respectively. Through comparative analysis, it is concluded that combustion and heat transfer performance of double burners is better than that of single burner. These conclusions can provide reference for the design and operation of supercharged boiler.
