Biomass cooking heating furnace

Abstract

The invention relates to a biomass cooking heating furnace. The biomass cooking heating furnace can be formed by one water heating unit and multiple cooking units to achieve multiple purposes. By adopting the double-mode design of natural air distribution and constraint air blasting, various firepower requirements can be met. By combining oxygenizing limiting and multi-stage oxygen supplying and combusting, according to the concentration of combustible gas, the amount of the oxygen supplying can be automatically optimized. According to step combining of oxygen supplying pipes with different shapes and apertures, the higher turbulence disturbance effect can be generated to prompt the sufficient degree of oxygen fuel gas mixing. Due to a fin type heat exchanger, the heat-exchange area is greatly increased. Due to special combining of a cooking combustor and a transverse exhaust gas channel, a hollow burning pot can be used inside, and efficient water boiling is carried out. Due to the wide adaptive capacity on the biomass fuel, the biomass cooking heating furnace can be used in the wide agricultural and pastoral area, can be matched with biomass forming fuel to replace a coal-based furnace which has the polluting emission, and can be popularized in cities and towns.

Description

technical field [0001] The invention relates to a biomass cooking and heating stove. Background technique [0002] Extensive use of fossil energy has caused serious environmental pollution, destroyed the ecological balance, induced various diseases, and damaged people's health. And fossil energy is non-renewable, and its depletion has gradually restricted economic development and increased people's living costs. Energy saving and emission reduction and the development of renewable energy are the general trend. [0003] Biomass energy is both a traditional energy source and a renewable energy source, and its total consumption is second only to non-renewable coal, oil and natural gas. Since biomass energy is mainly the energy accumulated by plant photosynthesis, plants absorb carbon dioxide from the atmosphere when they grow, and then release the absorbed carbon dioxide when they are burned. This is a carbon cycle that does not increase the carbon dioxide in the atmosphere, ...

Problems solved by technology

[0009] In order to overcome the defects of the above-mentioned biomass stoves such as that fans cannot be used, fans must be used, chimneys must be used, chimneys cannot be used, pellet fuel must be used outdoors, or pellet fuels must be used, the technical problem to be solved by the present invention is to provide Such a biomass cooking and heating stove can adapt to various biomass fuels such as straw, firewood, cattle and sheep dung, densely formed briquettes and granules, and can use fans or neither fans nor chimneys. The situation where the chimney must be used is limited to indoor use for the sake of absolute safety. It can be perfectly combined with various biomass boilers on various occasions. It can cook and heat. Not only the operation method is the same as the traditional rural stove Strong firepower and full combustion can still be achieved even without the use of fans and chimneys
