Abstract

A method and system are disclosed for achieving reduced mercury emissions from a power plant at a minimum cost. The parameters of the combustion chamber and a sorbent injector are manipulated to control the residual carbon in ash and the injected sorbent. These two elements combine to reduce mercury in the exhaust gas to an acceptable level.
