A vapor recovery system in which gasoline vapors or other flammable vapors are withdrawn from the vicinity of a like, and are disposed of by combustion in a burner system, preferably consisting of two burners selectively usable for burning vapor-air mixtures of different B.T.U. contents. The vapors may be temporarily stored by adsorption onto an adsorbing substance, and then be removed from that substance by conducting a flow of air therepast.
