High Temperature Turbine Technology: Summary of Four Integrated Gasification and Overall Plant Design Descriptions

摘要

Four industrial gas turbine manufacturers were contracted by the US Department of Energy to perform Phase I, Program and System Definition, of the High Tempeture Turbine Technology Program. Each contractor prepared an Overall Plant Design Description of a combined cycle power plant with integrated coal gasification. These combined cycles employed a primary cycle gas turbine with firing temperatures in the range of 2600 exp 0 F to 3000 exp 0 F through the use of advanced turbine combustors and turbine blade cooling techniques. Conventional steam plant technology was applied in the bottoming cycle whih together with the primary cycle gas turbine showed promise for coal pile to bus bar thermal efficiencies ranging from 40 to 47%. These plants are described, and the material and energy balances are presented. (ERA citation 04:053140)
