| Abstract: | Aiming at the problems encountered by a 1 025 t/h W-shape flame boiler,such as superheater overheating and poor flame stability etc.,simulation tests on flow characteristics in the furnace were carried out on a cold state test rig.By numerically simulating the distribution ratio of primary to secondary air with software FLUENT,the influence of different air distribution modes on flow characteristics in the furnace of W-shape flame boilers is then obtained. |
