A combined cycle power generation plant includes a boiler for producing steam, the boiler including a furnace for combusting first fuel to produce flue gas, a back-pass for receiving the produced flue gas and a flue gas duct for passing the flue gas from the back-pass to the environment, a process gas supply for supplying processed gas to the furnace, a steam turbine for receiving and being driven by the steam to generate power, a combustor for combusting a second fuel to produce exhaust gas, a gas turbine for expanding the exhaust gas from the combustor to generate power and for passing the exhaust gas to the process gas supply. The boiler is designed to provide effective steam production and low emissions to the environment in first operating conditions of the combustor when using exhaust gas alone or as a major portion of process gas being supplied to the boiler. |
