Alcohol-based fuel gasification combustion stove

Abstract

The invention provides an alcohol-based fuel vaporizing combustion furnace, which belongs to the technical field of a combustion furnace and aims at solving the problems that in the prior art, the blockage can easily occur, and the heated temperature difference is great, so that the furnace is damaged, the starting time is long, and the noise is great. The alcohol-based fuel vaporizing combustion furnace comprises a backflow heat-resistant filtering unit, a vaporizing unit, a fire intensity control unit, a heating starting unit, a fire spraying unit and a preheating unit, wherein the vaporizing unit is communicated with the backflow heat-resistant filtering unit through a material supply pipe; the fire intensity control unit is communicated with a vaporizing cavity branch pipe vaporizing unit; the heating starting unit and the fire spraying unit are communicated with the fire intensity control unit; the fire spraying unit comprises a fire spraying head and a fire spraying cavity; the fire spraying head comprises a fire distribution cap and a connecting rod; the fire distribution cap is in contact with a conical surface arranged at the upper end of the fire spraying cavity, so that the lower part of the cavity forms a gas spraying chamber, and the upper part of the cavity forms an annular spray nozzle; the lower end of the connecting rod is connected with the lower end of the fire spraying cavity through screw threads; a plurality of fire spraying grooves are uniformly distributed in the circumference of the lower end of the fire distribution cap; a gap is formed in the fire spraying cavity and the vaporizing cavity for forming an air distribution opening; an ignition needle is arranged in any position of the air distribution opening; the preheating unit is connected with the lower end of the fire spraying cavity of the fire spraying unit through screw threads.

Description

technical field [0001] The invention belongs to the technical field of combustion stoves, in particular to an alcohol-based fuel vaporization combustion stove. Background technique [0002] Now the renewable alcohol-based clean fuel mainly based on methanol has been recognized and widely used in the world. It has the characteristics of simple production process, wide range of sources, low price, good combustion emission, and easy degradation. In terms of safety, environmental protection, and economy, it is an excellent fuel, especially alcohol-based fuels are widely used in the catering industry and heating industry. [0003] For many years, the realization of vaporization combustion of alcohol-based fuels has been a dream of people. During the process of vaporization and combustion, because the vaporization temperature cannot be controlled, a large amount of charcoal is sucked out along with pyrolysis when the fuel is vaporized at high temperature, which leads to blockage ...
