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.

A gas stream with a reduced oxygen concentration relative to ambient air is used to vaporize a liquid fuel or liquified higher hydrocarbon gas, or is mixed with a vaporized gas, and the reduced oxygen vaporized fuel gas is fed to a combustion device such as a premixed or diffusion combustor. Preferably, the oxygen content of the gas stream is less than the limiting oxygen index. By mixing the fuel with a gas stream that has an appropriately reduced oxygen content, auto-ignition prior to the flame front can be avoided. In some embodiments, the reduced o...

What is claimed is: 1. A method for operating a combustion device, the method comprising the steps of: producing a fuel gas using a liquid fuel comprising hydrocarbon molecules and a first gas stream with an oxygen content less than that of ambient air; premixing the fuel gas and a second gas to produce a gas mixture at a location upstream of a combustion zone of a combustion device, the second gas including oxygen; and combusting the gas mixture in the combustion zone of the combustion device, whereby auto-ignition of the gas mixture upstream of the combustion zone is substantially suppressed. 2. The method of claim 1, wherein the gas mixture has an amount of oxygen sufficient to support combustion of the gas mixture. 3. The method of claim 1, wherein the gas mixture is a lean mixture with an equivalence ratio less than 1. 4. The method of claim 1, wherein at least 50 weight percent of the hydrocarbon molecules of the liquid fuel have at least two carbon atoms. 5. The method of claim 1, wherein the oxygen content of the first gas stream is below a limiting oxygen index of the liquid fuel. 6. The method of claim 1, wherein the combustion device includes a fuel metering system configured for natural gas. 7. The method of claim 1, wherein the first gas stream is supplied by an air separator. 8. The method of claim 7, wherein the air separator produces the first gas stream using adsorption. 9. The method of claim 1, wherein the reduced oxygen gas stream is supplied from an exhaust of a pre-burner. 10. The method of claim 1, wherein the reduced oxygen gas stream is supplied from an exhaust of the combustion device. 11. The method of claim 1, wherein an equivalence ratio of the gas mixture is less than a minimum equivalence ratio at which methane could be combusted under equivalent operating conditions. 12. The method of claim 1, wherein the liquid fuel is diesel fuel. 13. The method of claim 1, wherein the liquid fuel is heating oil. 14. The method of claim 1, wherein the liquid fuel is butane. 15.
