SYSTEM AND METHOD FOR REMOVING MERCURY IN EXHAUST GAS

摘要

A biomass feeding unit (11) feeds biomass to a boiler (1). A hydrogen-chlorine monitoring unit (12) measures hydrogen-chloride content in flue gas fed to a desulfurization equipment (2). A mercury monitoring unit (13) measures mercury content in treated flue gas emitted from the desulfurization equipment (2). A feed-amount instruction unit (14) instructs proper feed amount of the biomass to the biomass feeding unit (11) based on measurement values obtained by the hydrogen-chlorine monitoring unit (12) and the mercury monitoring unit (13).
