Abstract

Acid dew point is one of the important parameters in boiler design and operation. Its height is closely related to the flue gas temperature, boiler efficiency, coal consumption and the utilization of flue gas waste heat at the tail of the boiler. In this paper, from the point of view of the sulfur content of coal, the concentration of SO3 and the content of water vapor after burning, the common acid dew point estimation formula is used to estimate the corresponding acid dew point value, and the results are analyzed. The results show that the acid dew point and sulfur content coal, coal combustion and SO3 concentrations of water vapor basic related, compared with the A.G.Okkes formula, .A.Bapahoba formula for estimation of the error is small, the former Soviet Union of the empirical formula of acid dew point value is low.
