A gasifier for disposing of biomass and other waste materials through a gasification and combustion process. The gasifier includes a primary chamber for receiving and holding biomass or a selected waste product. A heat transfer chamber is disposed adjacent the primary chamber. A burner is associated with the gasifier for generating heat and heating the gasifier during various phases or portions of the gasification and combustion process. In the gasification process, the heat transfer chamber is heated and the heat is transferred to the primary chamber where the biomass is heated. During the gasification process, biomass material is volatized generating fumes and gases that later react and release heat through exothermic reactions. Once the gasification process has been concluded, the process enters a combustion phase where the biomass is actually burned. During the gasification-combustion phases, the amount of heat supplied by the burner will vary. Generally the amount of energy or heat supplied by the burner will decrease throughout the process because the biomass itself will supply substantial amounts of heat through exothermic reactions.

The invention refers to the method for the utilization of low-concentration mixtures of a combustible gas and air with the stable recovery of heat and the flow-reversal device for the embodiment of the method. The method consists in the combustion, with heat recovery, of the mixtures in the flow-reversal device having at least a single pair of combustion sections, each of which has the structural packing of monolith blocks with small channels characterized by low pressure drop, provided with an internal heating device, temperature and composition sensors and the elements of the automatic control system, supplied with the low-concentration mixture with the combustible component and connected with the heat recovery apparatus through the pipeline, wherein the quantity of energy transferred in the heat recovery apparatus (22) is stabilized by supplying additional fuel to the flow-reversal device, selecting the flow reversal moment, and selecting the flow rate for hot gas supplied by the pipeline to the heat recovery apparatus (22). Additional fuel in the form of highly concentrated fuel mixture is introduced as an admixture to the stream of low concentrated mixture containing the combustible component, supplied to the flow-reversal device or to the internal heating device (7). The device according to the invention, in its combustion sections (I, II) is provided with symmetrical temperature sensors (T.sub.I, T.sub.II) and an additional supply of highly concentrated combustible mixture (17) connected to the supply system for low-concentration mixture (15) with the combustible component or to the internal heating device (7). The combustion sections (I, II) are packed with heat-accumulating material (1,2) of small porosity of the specific surface area below 30 m.sup.2/g, and advantageously below 1 m.sup.2/g.
