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

Improved methods for the destruction of methane gas within a colliery ventilation stream are provided that include the efficient utilization of the energy obtained from the oxidation of the methane gas. In practicing the methods, a colliery vent gas, containing a dilute concentration of methane in air, is oxidized within a matrix bed of heat resistant material to convert the methane to oxidation products with the simultaneous release of heat energy. The heat energy is recovered to thermally heat a working fluid used to operate a steam turbine to produce ...

청구항

[ What is claimed is:] [1.] A method for destroying methane within a colliery ventilation stream with a concomitant recovery of energy, comprising:(a) directing with a ventilation fan a colliery vent gas comprising methane in an amount below about 3% by volume and air to an inlet of a plenum of a flameless oxidizer, wherein the ventilation fan is closely coupled to the plenum inlet, and the plenum is located upstream of a matrix bed of inert heat resistant material and has sloping sidewalls such that the cross sectional area of the plenum increases in th...
