Liquid fuel vaporization combustion device

Abstract

The invention relates to a liquid fuel vaporization combustion device which comprises a vaporization device (1), a vaporization device liquid inflow pipe (11) and a vaporization device gas outflow pipe (12) which are connected with the vaporization device (1), a preheating device (2), a preheating device liquid inflow pipe (21) connected with the preheating device (2), and a vaporization nozzle (13) connected with the gas outflow pipe (12), wherein the vaporization device (1) is annular, and a bottom wall (14) of the vaporization device (1) is recessed inwards to form 2 to 18 conic or truncated-cone-shaped bottom wall protrusions (15); a circle of liquid inflow groove (16) is fixed to the upper half portion of the side wall of the vaporization device (1) and the position, corresponding to each bottom wall protrusion (15), of the liquid inflow groove (16) is provided with a chute (17); and the gas outflow pipe (12) is connected to the top of one end of the vaporization device (1). By the adoption of the liquid fuel vaporization combustion device, liquid fuel can be completely vaporized and fully burnt, and combustion efficiency is improved.

Description

technical field [0001] The invention relates to a liquid fuel gasification combustion device, which belongs to the field of combustion devices. Background technique [0002] Some existing liquid fuel stoves are prone to incomplete combustion, resulting in carbon deposits, peculiar smells, and black smoke. Liquid fuel stoves mostly use vaporization devices, some of which use vaporization tubes installed at the bottom of the burner, and use the method of opening holes in the burner to let a part of the vaporization gas spray out to burn and heat the vaporization tube, which will affect the intensity of the main flame and reduce the thermal efficiency; some The vaporization tube is installed horizontally on the top of the burner, causing the main firepower to be split into two halves, reducing the thermal efficiency; Chinese Patent Publication No. CN2079290 discloses a liquid fuel furnace (stove) burner, which discloses a tube type vaporization combustion The device is prone t...

[0002] Some existing liquid fuel stoves are prone to incomplete combustion, resulting in carbon deposits, odors, black smoke, etc.

Liquid fuel stoves mostly use vaporization devices, some of which use vaporization tubes installed at the bottom of the burner, and use the method of opening holes in the burner to let a part of the vaporization gas spray out to burn and heat the vaporization tube, which will affect the intensity of the main flame and reduce the thermal efficiency; some The vaporization tube is installed horizontally on the top of the burner, causing the main firepower to be split into two halves, reducing the thermal efficiency; Chinese Patent Publication No. CN2079290 discloses a liquid fuel furnace (stove) burner, which discloses a tube type vaporization combustion The device is prone to partial vaporization in the tube, which will cause the local pressure in the vaporization tube to rise, and the liquid fuel will be ejected, resulting in incomplete vaporization and reduced combustion efficiency.
