| Abstract: | In order to stably lower combustion load, a concept of quasi constant temperature combustion based on movable heat insulate layer is put forward for pulverized coal. The feasibility of the quasi constant temperature combustion is discussed by using a thermodynamic model. The effects of the quasi constant temperature combustion on flue gas and steam temperature, stable combustion ability and combustion efficiency are analyzed in detail. The results show that the quasi constant temperature combustion can greatly improve overall performances of a boiler. |
