EFFECT OF SECONDARY AIR ON SOOT NUCLEUS PRODUCTION IN STOKER-FIRED BOILERS

Abstract

Black smoke emission and soot nucleus production in a stoker-fired boiler by secondary air are studied numerically and experimentally. Temperature field, flow field, and soot nucleus concentration are predicted numerically. It reveals that the secondary air gives about 10% reduction of the soot nucleus production, and the black smoke emission is controlled evidently.
