연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

초록

A system and method for recovering heat from dirty gaseous fuel (syngas), wherein the pressure of clean fuel gas is elevated to a pressure higher than that of the dirty syngas and then the pressurized clean fuel gas is fed to a heat recovery unit for heat exchange with the dirty syngas. Consequently, in the event of a leak in the heat recovery unit, the flow is from the clean fuel side to the dirty syngas side, thereby avoiding the possibility of contamination of the clean fuel gas.

What is claimed is: 1. An integrated gasification power plant including: a heat recovery unit comprising a heat exchanger for recovering heat from produced gaseous fuel, in advance of gaseous fuel purification with a gaseous fuel purifier to produce clean fuel gas, by elevating the temperature of the produced clean fuel gas through heat exchange with the gaseous fuel, a compressor for elevating the pressure of said clean fuel gas upstream of the heat exchanger to a pressure greater than a pressure of the gaseous fuel in the heat exchanger such that, in ...
