| Abstract: | Cold model tests are carried on in 300MW low NOx opposing concentric tangential firing boiler about flow field in furnace and concentration field near burner nozzle. The aim of this paper is to study the effect of the secondary air deflection angle, velocity pressure ratio of secondary air to primary air, velocity pressure ratio of OFA to primary air and layout form of over fire air on the relative diameter of the tangential firing, turbulence magnitude, mixture of the primary air and the secondary air and the force of penetration of OFA. The effects of these factors on the performance of boiler are analyzed. Figs 7, tables 4 and refs 6. |
