Abstract
A biogas combustion system that obtains a stable output and saves energy is realized. A combustion system comprises a separation portionthat removes carbon dioxide from a treatment target gas containing a mixture gas containing methane as a main component and containing carbon dioxide to obtain methane gas of a high purity in which at least a content of carbon dioxide has been reduced, and a combustion portionthat combusts the methane gas. The separation portionincludes a first treatment chamberand a second treatment chamberseparated from each other by a separation membranetherebetween. The separation membraneselectively allows the carbon dioxide in the treatment target gas supplied to the first treatment chamberto pass therethrough to the second treatment chamberto obtain a first separation gas having a higher methane purity than the treatment target gas in the first treatment chamberand a second separation gas containing the carbon dioxide in the treatment target gas in the second treatment chamber
