A liquid fuel porous medium burner with cold flame evaporation

Abstract

The invention discloses a liquid fuel porous medium burner with cold flame pre-evaporation, which belongs to the field of micro-energy. The invention includes a pressure swirl nozzle, a cold flame gasifier fixing ring, a cooling water outlet, a combustion chamber water cooling channel, a combustion chamber shell, a cooling water drainage channel, a flue gas channel water cooling channel, a cooling water inlet, and a combustion chamber thermal insulation layer. Porous medium in combustion section, porous medium in preheating section, cold flame gasifier, insulation layer of cold flame gasifier, air inlet and burner upper cover, etc. The liquid fuel porous media burner combines cold flame pre-evaporation and micro-combustion technology, which can improve the combustion efficiency of the burner, reduce pollutant emissions, and has a wide burner power adjustment range and combustion equivalence ratio range. Users only need to supply liquid fuel to the pressure swirl nozzle to obtain the energy generated by combustion, which has the advantages of environmental protection, high efficiency and portability. The present invention generates energy by pre-evaporating the liquid fuel and then burning it, and can be used as an energy source for 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, belonging to the field of micro-energy. Background technique [0002] With the development of science and technology, the processing technology of micro-devices has become more and more mature, and people are paying more and more attention to micro-devices. At the same time, using liquid fuel as an energy source has the advantages of easy storage and high energy density compared with general gas fuels. However, while the micro-devices are becoming more mature and the demand is expanding, new requirements are also put forward for the power supply equipment in them. Using the micro-combustion device as the energy source of the power supply device is one of the choices, and the micro-combustion device is also required to have a shape. Small size, low pollutant emission...
