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 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 dual fuel vent free gas heater having at least one gas burner with a plurality of gas outlet ports. The gas outlet ports are in flow communication with at least one pilot flame burner. At least one fuel injector feeds fuel to the burner providing for introduction of more than one fuel to the burner. Optionally, an oxygen detection system, manual control valve, linkage, and/or shut off control system may be incorporated into the dual fuel vent free heater.

The invention claimed is: 1. A dual fuel gas heater comprising:a gas burner,a first pilot burner,a control valve situated to delivery either a first fuel or a second fuel to the gas burner and to the first pilot burner,a temperature sensor located adjacent the first pilot burner that generates an electrical voltage deliverable to the control valve upon being heated by a pilot flame emitted by the first pilot burner,a normally closed thermal switch located inside or in proximity to the gas burner that is located in the electrical flow path between the tem...
