Low concentration methane gas oxidation system using exhaust heat of gas turbine engine

摘要

Low-concentration methane gas oxidation that makes effective use of exhaust heat from a gas turbine engine and that can operate stably even if the methane concentration in the low-concentration methane gas to be treated suddenly increases, avoiding catalyst burnout, etc. Provide a system. In a low-concentration methane gas oxidation system (ST) that oxidizes low-concentration methane gas using exhaust heat of a gas turbine engine, the low-concentration methane gas supply source (VS) to be oxidized and the low-concentration methane gas as a catalyst A catalyst layer (15) that is oxidized by combustion, and a supply passage (SP) that supplies the low-concentration methane gas from the supply source to the catalyst layer, and an intake damper (external air introduced into the supply passage) 45).
