A Experimental Study on the Uneven Flow Distribution in the Windbox of an Oil-Fired Boiler

유류 연소 발전용 보일러에서 공기 공급 계통의 불균일성에 관한 실험적 연구

In the multi-burner power plant, uneven supplies of combustion air to multi-burner are induced by unbalanced flow distribution in the windbox. These flow patterns tend to make flame unstable, increase the formation of pollutants and lower the overall combustion efficiency. To prevent these disadvantages, flow patterns in the windbox should be investigated and made to be distributed uniformly, In this study, scaled windbox model was used for tests and measured the velocities at the exit of the each burner and compared those with the CFD results.
