Performance of Coal-Gasification-Reheat Combustion-Turbine Power Cycles Using Dry Cooling. Final Report (Texaco Oxygen-Blown Gasifier and British Gas Corporation Slagging Gasifier)

摘要

A study was conducted to explore the near-term performance potential of coal-gasification combined cycles that use reheat combustion turbines and dry cooling. The major finding is that these cycles can have coal-to-bus-bar efficiencies close to 40% if the components are properly matched. The study assumes that reheat gas turbines with inlet temperatures of about 2370 exp 0 F could be developed. The addition of an ammonia cooling loop in the condenser system improved the efficiencies and reduced the cooling tower sizes. 30 figures, 55 tables. (ERA citation 08:035031)
