Description

Biomass fuel cooking water heating and kang ventilation integrated furnace

Technical Field

The invention relates to a biomass fuel cooking water heating and kang ventilation integrated furnace, and belongs to the field of civil biomass stoves.

Background

Most biomass stoves on the market still adopt the form of traditional coal stove at present, and the fundamental principle is that fuel is sent into furnace chamber combustion chamber through the filler hole and is burnt, and the flue gas is discharged outdoors by the flue, and partial stove type supplies indoor heating through heat radiation, and in addition, partial stove type flue, the stove section of thick bamboo are around designing annular water jacket, and water jacket design inlet outlet, hot water access heating circulation system after the heating, and this kind of stove mainly is used for winter heating, and some heightening furnace body also can be used for cooking.

The biomass particle heating fireplace is used in part of regions, biomass particles are conveyed from a bin to a fuel combustion chamber intermittently or continuously through an automatic feeding system, and heat generated by biomass particle combustion is conveyed to a heating region in a hot air mode through a ventilation system.

In addition, a class of biomass stove is reformed transform by traditional firewood kitchen to cooking is leading, and partial stove type utilizes flue gas waste heat, is furnished with the water tank, and hot water only is used for daily use, does not regard as the heating to use, and this type of stove generally is used for outdoor cooking to use.

In recent years, biomass particle stoves integrating multiple functions such as cooking and heating are developed successively, biomass particle materials are conveyed to a fuel combustion chamber continuously or intermittently by using an automatic feeding system similar to a heating fireplace, a gasification combustion mode is mostly adopted, flames come out through a fire outlet and then heat a boiler body, through water tanks are distributed around a boiler body and a flue, and water is heated by absorbing heat to be used by a heating system.

The biomass stove in the traditional coal stove form has the defects of single function, lower fuel combustion efficiency and comprehensive utilization efficiency, larger heat loss, easy scald caused by high temperature on the surface of the stove body and the like. Because the calorific value of the biomass fuel is much lower than that of fire coal, the biomass fuel has good inflammability and is not burning-resistant, and the purpose of slow burning of heating and fire banking is difficult to realize, most of the stoves have low automation degree, cannot provide a continuous automatic feeding function, and are troublesome to use.

In recent years, biomass stoves which integrate multiple functions of cooking, heating and the like are developed successively, biomass particle raw materials are taken as main materials, and automatic feeding multifunctional mature stoves suitable for massive biomass fuels are not available. Such conditions arise primarily because: compared with a pressing material, the particle size of the particle material is smaller, the material type is more uniform, automatic conveying is facilitated, the purposes of pushing, reverse burning prevention and the like can be achieved by adopting spiral conveying, and the particle material is small in diameter and not easy to clamp; the diameter of the briquetting material block is larger, generally more than 2-3cm, the briquetting material block is influenced by factors such as briquetting process and equipment, the length is extremely uneven, and the briquetting material block is obviously not suitable for feeding in the manner. Meanwhile, the existing furnaces are difficult to be in an automatic feeding structure, the size of biomass particles is generally required to be below 8mm, the length of the biomass particles is required to be below 3cm, large-block-diameter hard impurities cannot be mixed in the biomass particle raw materials, otherwise, the feeding system can be damaged, the furnaces have high requirements on the raw materials, and the raw materials are not high in applicability. However, the requirements of biomass granulating raw materials, processes, equipment and the like are more complex than those of briquetting, the processing cost is high, and the use economy is lower.

Therefore, there is a need to provide a new biomass fuel stove for cooking, heating and kang ventilation to solve the above technical problems.
