- Abstract
To take 1 single capacity 58MW pulverized coal fired hot water boiler manufactured by Shanxi Lantian Environmental Protection Equipment Co., Ltd as research object, by using FLUENT fluid calculation software to carry out numerical simulation calculation on the velocity field, temperature field, the concentration of oxygen inside the chamber combustion boiler which equipped hedge rotational flow burner. The calculation results showed that: when the boiler was at high load, perturbation action of stream field was more obvious with the increase of inner secondary air and outer secondary air ratio, when the boiler was at low load, the variation of the inner secondary air and outer secondary air ratio almost didn't affect the perturbation action of stream field; when at the same load, fly ash carbon content of furnace outlet was less with the increase of the inner secondary air and outer secondary air ratio, pulverized coal burning rate increased correspondingly.
