Abstract

Abstract: In order to achieve high efficient green power generation and reduce mercury emissions from coal-fired power plants, according to the requirements of “Pilot Experiment of Mercury Control in Coal-Fired Power Plant” issued by the Ministry of Environmental Protection of China, testings on mercury control technique with fly ash based sorbent spray are carried out in Guohua Sanhe Power Plant on the basis of mercury emission concentration measurement. Through the testing, the feasibility of fly ash based sorbent spray method is verified. As a technology of high mercury removal efficiency, it can lower the mercury emission concentration further by 30%~50% with the mercury removal efficiency reaching as much as 75%~90% by taking advantage of the existing pollutant control equipments such as desulfurization, denitrification, dust removal and mercury removal. In this way, the mercury emission concentration in the flue gas can be lowered down far less than the national standard. Hence, the application of fly ash based sorbent spray method shows a prospect of popularization.

Key words: thermal power plant, modified sorbent, mercury removal, fly ash
