The invention relates to a device and a method for thermal treatment of a raw material in an oscillating hot gas flow of a pulsation reactor, comprising a burner, which is supplied with a mass flow, via at least one pipeline, for forming at least one flame, which produces the oscillating hot gas flow, wherein the flame is arranged in a combustion chamber, and wherein a reaction chamber follows the combustion chamber downstream of the combustion chamber. In order to be independent of the dimension of the device, it is proposed to provide the mass flow that is supplied to the flame with an externally impressed pulsation. The combustion chamber and/or the reaction chamber can then be varied in geometry to avoid resonances.

A pulse jet system and method is disclosed. In an example, the pulse jet system includes a combustion chamber, intake ports to deliver combustion agents to the combustion chamber, an expansion chamber to cool a combustion product following combustion of the combustion agents in the combustion chamber, and an exhaust to exit the cooled gas from the expansion chamber. In another example, the pulse jet system includes a combustion chamber with intake ports to deliver combustion agents to the combustion chamber, wherein the combustion chamber is part of a four cycle engine. The pulse jet system also includes an expansion chamber to cool a combustion product following combustion of the combustion agents in the combustion chamber.

Disclosed herein is a use of pulsed combustion to convert chemical energy to usable heat. For example, in boilers, heat is generated by burning fuel at burners and transferring the heat to water or other fluids, including air, through heat exchangers. In one form, these heated fluids may then be utilized to assist in removing oil from oil sand reservoirs.

This invention refers to the energy sector and can be applied in heating systems, in particular in water heaters or boilers; in disposal systems operating on associated gas flaring. The pulsating combustion device comprises a combustion chamber and, connected thereto, an air and fuel gas supply unit and a flue duct. Said flue duct comprises at least one resonance pipe connected to the combustion chamber and at least two Helmholtz resonators located successively downstream of the at least one resonance pipe. Each of said resonators consists of a flue chamber and a flue pipe arranged downstream thereof, and natural resonance frequency of each of the Helmholtz resonators is less than combustion pulsation frequency. The invention allows to increase the pulsating combustion device efficiency with a simultaneous reduction of the noise level.
