Abstract: A low-concentration methane gas oxidation system is provided which effectively uses exhaust heat from a gas turbine engine and is able to avoid burnout of a catalyst etc. to enable stable operation even when a methane concentration in a low-concentration methane gas which is a treatment target is rapidly increased. In a low-concentration methane gas oxidation system which oxidizes a low-concentration methane gas by using exhaust heat from a gas turbine engine, a supply source of the low-concentration methane gas which is an oxidation treatment target, a catalyst layer configured to oxidize the low-concentration methane gas by catalytic combustion, and an intake damper connected to a supply passage through which the low-concentration methane gas is supplied from the supply source to the catalyst layer and configured to introduce an air from an outside into the supply passage, are provided.

Abstract: A fluid mixing device includes a hollow tubular main body (41) to mix an exhaust gas (G4) and a warming gas (G5) within it, a first inflow port (43) provided in an upstream end portion of the main body (41) and through which the exhaust gas (G4) flows, a mixing promotion body (38) of a tubular shape disposed inside the main body (41) and having a longitudinal axis (C1) extending in a direction conforming to a direction of flow of the exhaust gas (G4), and a second inflow port (45) provided in a peripheral wall of the main body (41) and through which the warming gas (G5) flows towards an outer peripheral wall of the mixing promotion body (38). The exhaust gas (G4) flows outside and inside the mixing promotion body (38).
