Low-concentration methane gas oxidation system using gas turbine engine waste heat

According to a low-concentration methane gas oxidation system of the present invention, waste heat from a gas turbine engine may be used effectively, and a stable operation may be available by avoiding a burning of a catalyst even in a case where a methane concentration in a target low-concentration...

Beschreibung
Zusammenfassung:	According to a low-concentration methane gas oxidation system of the present invention, waste heat from a gas turbine engine may be used effectively, and a stable operation may be available by avoiding a burning of a catalyst even in a case where a methane concentration in a target low-concentration methane gas rises abruptly. The low-concentration methane gas oxidation system (ST) of the present invention which uses the gas turbine engine waste heat to oxidize the low-concentration methane gas comprises a source of supply (VS) of the low-concentration methane gas which is the target of oxidation, a catalytic layer (15) which oxidizes the low-concentration methane gas by way of catalytic combustion, and an intake damper (45) which is connected to a supply passage (SP) which supplies the low-concentration methane gas from the source of supply to the catalytic layer to guide outside air into the supply passage.
