The invention discloses a liquid fuel porous medium combustor with a cold flame pre-evaporation function, and belongs to the field of micro energy. The liquid fuel porous medium combustor comprises apressure swirl nozzle, a cold flame gasifier fixing ring, a cooling water outlet, a combustion chamber water cooling channel, a combustion chamber shell body , a cooling water drainage channel, a fluegas channel water cooling channel, a cooling water inlet, a combustion chamber heat insulation layer, a combustion section porous medium, a preheating section porous medium, a cold flame gasifier anda cold flame gasifier heat insulation layer, an air inlet, a combustor upper cover and the like. According to the liquid fuel porous medium combustor, the cold flame pre-evaporation technology and the micro-combustion technology are combined, the combustion efficiency of the combustor can be improved, pollutant emission is reduced, and the wide combustor power adjusting range and the wide combustion equivalent ratio range are achieved. A user only needs to supply liquid fuel to the pressure swirl nozzle to obtain energy generated by combustion, and the liquid fuel porous medium combustor hasthe advantages of being environmentally friendly, efficient and portable. The liquid fuel is pre-evaporated and combusted to generate energy, and the energy can be used as an energy source of micro-miniature equipment.
Description
technical field [0001] The invention relates to a liquid fuel porous medium burner with cold flame pre-evaporation, in particular to a porous medium burner using liquid fuel and having pre-evaporation capability, which belongs to the field of micro-energy. Background technique [0002] With the development of science and technology, micro-device processing technology has become more mature, and people are paying more and more attention to micro-device. At the same time, using liquid fuel as an energy source has the advantages of easy storage and high energy density compared with general gaseous fuel. However, as the micro-equipment matures and the demand expands, new requirements are put forward for the power supply equipment. Using the micro-combustion equipment as the energy source of the power supply equipment is one of the choices, and the micro-combustion equipment is also required to have a shape It has the characteristics of small size, low pollutant emission, wide ra...
