Selection of an industrial natural-gas-fired advanced turbine system - Task 3A

摘要

The task objectives are to identify a gas-fueled turbine and steam system which will meet the program goals for efficiency and emissions. The goals for the Advanced Turbine System Program (ATS) where outlined in the statement of work for five basic categories are: Cycle Efficiency - System heat rate to have a 15% improvement over 1991 vintage systems being offered to the market. Environmental No post-combustion devices while meeting the following parameter targets: (1) Nitrous Oxide (NOx) emissions to equal 8 parts per million dry (ppmd) with 15% oxygen. (2) Carbon monoxide (CO) and unburned hydrocarbon (UHC) emissions to equal 20 parts per million (ppmd) each. Cost of electricity to be 10 percent less when compared to similar 1991 systems. Fuel Flexibility Have to ability to burn coal or coal derived fuels without extensive redesign. Reliability, Availability, Maintainability Reliability, availability and maintainability must be comparable to modern advanced power generation systems. For all cycle and system studies, analyses were done for the following engine system ambient conditions: Temperature - 59 deg F; Altitude - Sea Level; Humidity - 60%. For the 1991 reference system, GE Aircraft Engines used its LM6000 engine product offering for comparison of the Industrial System parameters developed under this program.
