HEAT RECOVERY GENERATING SYSTEM AND METHOD OF ITS OPERATION

摘要

PROBLEM TO BE SOLVED: To cope with both fluctuating cold load and power load, in a heat recovery generating system. SOLUTION: A generator 34 is connected to a gas turbine 32. An exhaust heat is generated from the gas turbine and the exhaust heat is guided to an exhaust heat recovery boiler 27 being a steam generating means. A condensing extraction steam turbine 1 is driven by steam generated by the boiler and a compressor 7 is driven by a power generated by the condensing extraction steam turbine. The compressor constitutes a turbo refrigerating machine A. A part of steam extracted from the condensing extraction steam turbine is used as a heating source for an absorption type refrigerating machine 14. A second generator 2 is situated between the condensing extraction steam turbine and the compressor.
