버너Windbox의 설계기술에 관하여

An experimental study for the improvement of combustion air distribution in the exit of burner windbox is carried out. Since the distribution of combustion air in the burner directly affects the stability and the shape of flame, it should be as uniform as possible. Furthermore multi-burner windbox should be designed to supply the suitable quantity of combustion air for each burner. For these purposes, thin splitting plates are installed in the windbox, which make the flow control and setup the circumferentially uniform pressure field at each windbox exit. The effect of splitters on the velocity distribution of combustion air is investigated by the use of a small sized two-burner windbox model having a dynamical similarity to the prototype. Even though not the best one, a configuration of splitters which seems to give a practically useful result is suggested.
