More Information
Summary:Provided is turbine plant using methanol as fuel in which working fluid is compressed by compressor 1 and led into combustor 2. A mixture of H2 and CO2 as fuel added with O2 is burned to generate high temperature gas, which works at high temperature turbine 3, flows through heat exchangers 4, 5 and returns partly to the compressor 1 and enters partly low pressure turbine 7 of bottoming system to work. Condensed water from condenser 9 of the bottoming system is pressurized by pressure pump 10 and flows through the heat exchangers 4, 5 to become high temperature steam and to work at high pressure turbine 6. Exhaust gas thereof is mixed into the combustor 2. A mixture of methanol and water is supplied into reformer 13 to absorb heat from the heat exchanger 4 to be reformed into H2 and CO2, which is supplied into the combustor 2. A high temperature portion of the high temperature turbine 3 is cooled by cooling medium extracted from compressor 1 outlet and high pressure turbine 6 outlet thereby reliability of the high temperature turbine 3 is enhanced.
