COMBUSTION SYSTEM

WIPO Patent Application WO/2017/154519

A1

The purpose of the present invention is to implement a biogas combustion system that can obtain a stable output and has low energy consumption. Provided is a combustion system provided with a separation unit 14 for eliminating carbon dioxide from a gas to be processed, which comprises a mixed gas that includes methane as a primary component and carbon dioxide, so as to obtain high purity methane gas wherein at least the amount of carbon dioxide is reduced, and a combustion unit 15 for combustion of methane gas, wherein the separation unit 14 has a first processing chamber 11 and a second processing chamber 12 partitioned by a separation membrane 13, and the separation membrane 13 selectively allows carbon dioxide in the gas to be processed that is supplied to the first processing chamber 11 to permeate through to the second processing chamber 12 so as to obtain a first separated gas in the first processing chamber 11 that has higher purity methane than the gas to be processed and a second separated gas in the second processing chamber 12 that includes the carbon dioxide in the gas to be processed.
