ABSTRACT:
An improved process for recovering a combustible gas including a first means for measuring the relative concentration of combustible gas and combustion-supporting gas before the gaseous mixture enters a gas recovering apparatus, and a second means for determining the relative concentration of combustible gas and combustion-supporting gas after the gaseous mixture leaves the gas recovering apparatus. The first gas detecting means prevents a gaseous mixture containing a combustible gas in a concentration less than the U.E.L. from entering the gas recovering apparatus. The second detecting means controls the gas recovering apparatus to insure that the concentration of combustible gas never falls below the upper limit of the detonation range.
