Environment-friendly hot air furnace using renewable fuels and biomass fuels

Abstract

The invention discloses an environmentally friendly hot blast stove that can use renewable fuel oil and biomass fuel, including a furnace body, a bio-regenerated fuel tank and a wet electrostatic precipitator. The lower end of the bio-regenerated fuel tank is provided with an oil supply pipe. The tube is connected with a regenerative fuel oil burner, and the interior of the furnace body is respectively provided with a combustion chamber and an array tube heat exchanger, the combustion chamber and the array tube heat exchanger are connected, and the side wall of the furnace body is provided with a furnace shell After the air supply mesh plate, the upper end of the furnace body is connected with the wet electrostatic precipitator through the flue gas discharge pipe. Environmentally-friendly hot air stoves that can use renewable fuel oil and biomass fuels can use renewable fuel oil burners to spray combustion flames for heating, and can also use biomass fuels such as straw briquettes, biomass particles, straw coal, etc., and fill them directly from the solid fuel furnace door Combustion on the cast iron bars in the hearth generates heat and expands the utilization rate of straw and other biomass, which is beneficial to the management and environmental protection of the prohibition of straw burning in the open air.

Description

technical field [0001] The invention belongs to the technical field of hot blast stoves, and in particular relates to an environment-friendly hot blast stove which can use renewable fuel oil and biomass fuel. Background technique [0002] my country is a big agricultural country, and the state supports the production and application of agricultural machinery. Grain purchase, storage, processing and other enterprises, agricultural professional cooperatives, and family farms all use grain dryers in large quantities, and the quality requirements for grain dryer machinery are getting higher and higher. [0003] The main heating equipment of traditional grain dryers provides hot air for heating equipment such as fuel oil, coal, chaff, electric heating, steam boilers, and heat-conducting oil furnaces. The hot air provided by the traditional fuel burner mainly uses non-renewable diesel and kerosene as energy. Coal-fired hot air stoves and coal-fired boilers also use non-renewable...

AI Technical Summary

Problems solved by technology

Coal-fired hot air stoves and coal-fired boilers also use non-renewable energy, and will generate large air pollution. In the case of direct heating, it will even pollute the dried grains.

Although electric heating equipment, such as heat pumps, use environmentally friendly energy, the initial purchase investment is huge, even higher than the price of the main body of the supporting grain dryer
