The invention relates to a high-efficiency low-pollution metal fiber pulsation combustor. The metal fiber pulsation combustor is characterized by comprising an air inlet pipe, a combustion cavity anda tail pipe, wherein the two ends of the combustion cavity are respectively connected with the air inlet pipe and the tail pipe, an upper gas distribution sleeve and a lower gas distribution sleeve are symmetrically distributed in the combustion cavity, gas inlet holes are uniformly distributed in the upper gas distribution sleeve and the lower gas distribution sleeve, a metal fiber net is arranged on the inner surface of the combustion cavity, a high-pressure discharge igniter is arranged in the combustion cavity, a fuel gas inlet pipe is arranged on the combustion cavity, and the combustionheat release position of the fuel gas inlet pipe is located at one quarter of the inner tube formed by the air inlet pipe and the tail pipe. According to the metal fiber pulsation combustor, the surface of the metal fiber is combined with the lining type pulsation combustion, the advantages of the metal fiber surface combustion and the lining type pulsation combustion are fully combined, the structure is simple, the whole device does not have a moving part, high in combustion efficiency, large in heat exchange coefficient, low in tail gas pollutant content and the like, and metal fiber pulsation combustor is a high-innovation ground pulsation combustion device.
Description
technical field [0001] The invention belongs to the technical field of pulsation combustion, relates to a pulsation burner, in particular to a metal fiber pulsation burner with high efficiency and low pollution. Background technique [0002] With the deepening of my country's energy-saving and emission-reduction work, the requirements for production processes and production equipment in all walks of life have been further improved, and the demand for advanced energy-saving technologies and supporting equipment has continued to increase. The process of converting fuel chemical energy into heat energy in various industries must be realized through burners, so the research on high-efficiency burners has become the focus of attention. Pulse combustion and metal fiber surface combustion are two high-efficiency and low-pollution combustion methods. [0003] Pulsating combustion refers to a periodic combustion process that occurs under acoustic shock conditions. In the pulsating ...
