Research on Ultra-low Emission Key Technology for Circulating Fluidized Bed Boiler and Its Engineering Application
摘要
Abstract
Traditional technologies in circulating fluidized bed (CFB) such as in-furnace desulfurization and low-temperature fractional combustion can not meet environmental protection requirement of near zero emission (that is ultra-clean emission), therefore, on the basis of combining control practices of pollutant emission of CFB boiler, this paper presents technical lines of adopting flue gas desulfurization technology of in-furnace desulfurization+tail wet desulfurization, combined denitration technology of selective non-catalytic reduction+selective catalytic reduction and wet electrostatic precipitator (WESP) technology so as to realize near zero emission of the CFB boiler, that is to reach the emission level of current gas turbine generators.Near zero emission technology is more favorable to fully exploit peculiar advantage of the CFB boiler of burning inferior and high-sulfur fuel, which is a necessary development trend of large-scale CFB boilers in future.关键词
