Efficient biofuel casting furnace and method of improving thermal efficiency

Abstract

The invention discloses an efficient biofuel casting furnace and a method of improving thermal efficiency, relates to an industrial casting furnace, and particularly relates to an aluminium product casting furnace using a novel fuel. The casting furnace is characterized in that the method of improving the thermal efficiency adopts a flowing air layer for surrounding a combustion furnace, the dissipated hot air is recycled to reduce heat loss and the water temperature is improved by the waste heat of burned stove ash; meanwhile, the air flow on a water surface is accelerated, the water vaporization is quickened, and the vaporized water is mixed with air in a combustion flame; liquid water can absorb a lot of heat during the vaporization, the heat loss is reduced, and the density and the specific heat capacity of the air in the combustion flame are increased, finally the combustion flame and the air in the combustion flame, the flowing air surrounding the combustion furnace and the recycled dissipated hot air are collected together, and the combustion temperature and the combustion thermal efficiency are improved. According to the invention, a bio-particle combustion material is adopted, so that the emission of sulfur dioxide, nitrogen dioxide, PM2.5, black smoke and the like is greatly reduced; the sustainability of energy sources is realized; the fuel temperature and the production efficiency are increased; and the energy consumption and the production cost are reduced.

Description

technical field [0001] The invention relates to an industrial melting and casting furnace, in particular to a new-type fuel aluminum melting and casting furnace. Background technique [0002] Most of the current industrial melting and casting furnaces use non-renewable resources such as petroleum gas and coal as combustion materials. As we all know, the resources of petroleum gas and coal are very limited, and the price of petroleum gas and coal is rising day by day, which directly affects the cost of downstream industries. Second: Combustion will release harmful gases such as sulfur dioxide and fine dust PM2.5, which will seriously affect the ecological environment and human health. Third: The high exhaust temperature will aggravate the greenhouse effect. Energy saving and emission reduction have become industrial boilers and industrial casting furnaces. New issues and severe challenges facing the future development of the industry. [0003] There are also boilers in the ...

[0002] Most of the current industrial casting furnaces use non-renewable resources such as petroleum gas and coal as combustion materials. As we all know, the resources of petroleum gas and coal are very limited, and oil The rising price of gas and coal will directly affect the cost of downstream industries. Second: combustion will release harmful gases such as sulfur dioxide and fine dust PM2.5, which will seriously affect the ecological environment and human health. Third: the exhaust gas temperature is high. Intensifying the greenhouse effect, energy saving and emission reduction have become new topics and severe challenges for the future development of the industrial boiler and industrial casting furnace industry

[0003] There are also boilers using wood pellet biomass fuel as fuel in the current market. Wood pellet biomass fuel uses wood pellets as biofuel. Smoke emission, fine dust PM2.5 emission exceeds the standard, and the combustion temperature is too low, which seriously affects the quality and production efficiency of the product
