Abstract
In order to provide a technique for enriching a combustible gas that allows enrichment of the combustible gas to a higher concentration in an efficient manner with minimization of loss of a source material, there are provided an adsorption tower charged with an adsorbent, a feeding/discharging means for feeding a source gas containing a combustible gas and air, a collecting means for desorbing the combustible gas adsorbed to the adsorbent and collecting the desorbed gas, a controlling means for sequentially effecting a combustible gas adsorption process and a combustible gas desorption process, a detecting means for detecting the concentration of the combustible gas in the source gas, and an operation condition setting section for varying an adsorption completion timing for the controlling means to complete the adsorption process, based on the combustible gas concentration detected by the detecting means.
