Description

Self-heating filtering type gasification combustion method and device for combustible liquid atomized particles

The technical field is as follows:

the invention belongs to the technical field of liquid fuel combustion, and particularly relates to a self-heating filtering type gasification combustion method and a device for combustible liquid atomized particles.

Background art:

the combustion method of alcohol stove is to pour the liquid fuel into a containable open container for ignition and combustion, and the defect of small flame height is that the liquid fuel is burnt in the container. The later development is in holding the even little gas pocket of splendid attire container bottom setting, utilizes the fan blast to blow high flame, has reached operation requirement. However, these techniques have obvious disadvantages, and 1, the container needs to be provided with a return pipe hole to limit the amount of fuel in the container. 2, the requirement on the levelness of the cooking bench is high, the levelness exceeds the limit, and the combustible liquid can flow to the lower side of the plane of the container, so that the container can overflow to cause safety accidents. 3 after starting ignition, waiting for fuel to flow into the bottom plane of the container, and having a certain time course, after closing the ignition, the flame is not extinguished immediately, but the residual materials in the container can be continuously burnt.

The combustion method of the atomizing furnace is that the pressurized liquid fuel passes through a nozzle with small aperture to form granular atomization and then is ignited for combustion. The disadvantages are as follows: the atomized incomplete combustion and partial particles are scattered and do not participate in combustion, and the fuel is wasted greatly and is eliminated. The later stage is through setting up first combustion chamber and reaching the purpose of abundant burning through modes such as blast air, sets up a plurality of fire holes around the first combustion chamber top, sets up the second combustion chamber, and the flame column that will follow fire hole spun gathers the cage together. The scheme is a mature combustion scheme at present and is widely applied to restaurants and kitchen houses. The disadvantages are that the stove cannot be applied in the household field because of the large volume of the stove, the large material consumption of the stove, the high cost and the like.

The electrothermal gasification stove is a new technology which is currently emerging and can be applied in the household field in a miniaturized way, a metal body is heated by a heating coil, and liquid fuel flowing through the metal body is gasified, expanded and sprayed out through an air hole arranged to ignite and burn. The advantages are that: the thermal power can be obtained by injecting the gasified expanded gas at a high speed without using a blower and mixing the gas with air for combustion. Meanwhile, the defect is obvious, when the burner is used, the burner metal body needs to be preheated to about 180 ℃ by the commercial power, the ignition can be started, and the process needs about several minutes. The long-term use of the commercial power energy is large in energy consumption and not beneficial to energy conservation.
