Abstract

In order to know about coke phenomena of 130t/h boiler with tangential firing, velocity and valves characteristics of primary and secondary air were measured. Fireworks test and numerical simulation were done at the condition of actual working and uniform air distribution, and the tangential circle diameter of actual working and uniform air distribution were obtained. The results show that the boiler will be satisfied basically with uniform air distribution in four corners on the condition that air velocity is adjusted uniformly in different jet, the ideal aerodynamic field in boiler will be obtained, and it provides reference for hot state run.
