Abstract

본 발명은 폐열회수보일러에서 발생된 중압증기의 일부를 가스터빈 사이클의 연소기내에 분사시켜 가스터빈의 동력을 증대시킬 수 있는 석탄가스화 복합발전시스템을 제공한다. 본 발명의 석탄가스화 복합발전시스템은 석탄가스를 생성하는 가스화기(2)와, 생성된 석탄가스를 연소기(5)를 통해 연소시켜 이 연소가스에 의해 동력을 발생시키는 가스터빈(7)과, 가스터빈(7)에서 배출된 연소가스를 유입하여 고압증기와 중압증기 및 저압증기를 발생시키는 폐열회수보일러(9)와, 폐열회수보일러(9)에서 발생된 고압증기와 중압증기 및 저압증기를 각기 유입 팽창시켜 동력을 발생시키는 고압증기터빈(27)과 중압증기터빈(28) 및 저압증기터빈(29)으로 이루어진 증기터빈(10)을 구비하여, 폐열회수보일러(9)의 중압증기의 일부를 연소기(5)내에 분사시켜 석탄가스와 함께 연소시킴으로써 가스터빈(7)의 동력을 증대시킨다.The present invention provides a coal gasification combined cycle power generation system that can increase the power of the gas turbine by injecting a part of the medium pressure steam generated in the waste heat recovery boiler into the combustor of the gas turbine cycle. The coal gasification combined cycle power generation system of the present invention includes a gasifier (2) for generating coal gas, a gas turbine (7) for generating power by the combustion gas by burning the generated coal gas through a combustor (5), High-pressure steam, medium-pressure steam, and low-pressure steam generated from the waste heat recovery boiler (9) and the high-pressure steam, medium pressure steam and low pressure steam by introducing the combustion gas discharged from the gas turbine (7). A part of the medium-pressure steam of the waste heat recovery boiler 9 is provided with a steam turbine 10 composed of a high-pressure steam turbine 27, a medium-pressure steam turbine 28, and a low-pressure steam turbine 29, each generating and expanding power. Is injected into the combustor 5 and combusted with coal gas to increase the power of the gas turbine 7.
