SYSTEM AND METHOD FOR IMPROVED HEAT RECOVERY FROM FLUE GASES WITH HIGH SO3 CONCENTRATIONS

摘要

Disclosed is a power generation system for high sulfur fuel combustion and a method of generating power from high sulfur fuel. The system includes a boiler for combusting a sulfur containing fuel to form a sulfur containing flue gas, a heat exchanger arranged and disposed to transfer heat from the sulfur containing flue gas to combustion air, a sorbent injector arranged and disposed to inject sorbent into the sulfur containing flue gas, and a second stage heat recovery mechanism arranged and disposed to transfer heat from the sulfur containing flue gas.
