LOW-CONCENTRATED METHANE GAS OXIDATION SYSTEM USING THE HEAT OF EXHAUST GASES OF A GAS-TURBINE UNIT

摘要

1. The system of oxidation of low-concentration methane gas for oxidation of low-concentration methane gas by using the heat of the exhaust gases of a gas turbine unit, and the oxidation system of low-concentration methane gas contains: a source of supply of low-concentration methane gas, which is the object of oxidative treatment; a catalyst layer made with the possibility of oxidation of low-concentration methane gas catalytic combustion; and an inlet valve connected to the supply channel through which the low-concentration methane gas is supplied from the supply source to the catalyst bed and which is configured to introduce air from the external environment into the supply channel when the methane concentration in the supply channel is higher than a predetermined value. The low-concentration methane gas oxidation system according to claim 1, wherein the supply channel is connected to an exhaust valve configured to release gas in the supply channel to the external environment when the methane concentration in the supply channel is higher than a predetermined value. The low-concentration methane gas oxidation system of claim 1, wherein the gas turbine unit is a lean-fuel gas turbine using low-concentration methane gas supplied from a supply source as a working gas, with an inlet valve connected to the downstream side of the nodal point, which branches off from the supply channel an auxiliary supply channel for supplying low-concentration methane gas to the gas turbine unit. 4.
