Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of agricultural and forestry waste biomass resource utilization technology, especially relates to an environmental protection and energy saving coal stove. BACKGROUND

[0002] With the continuous growth of global energy demand and the increasing awareness of environmental protection, developing environmentally friendly and energy-saving energy utilization technology has become an important issue in today's society. Agricultural and forestry wastes, such as straw, rice husk, waste bamboo, and branches, are a rich source of biomass resources with natural carbon neutral properties. After proper treatment, these wastes can be converted into efficient and clean energy to contribute to sustainable development. In this context, coal stoves, which can mix and burn agricultural and forestry wastes and combustible coal to improve combustion efficiency and reduce environmental pollution, have emerged and are widely used in industrial production, domestic heating, and other fields.

[0003] Currently, the coal stoves on the market usually include fuel inlets, hearths, water tanks, flues, and smoke outlets. The working principle is to directly send agricultural and forestry wastes and combustible coal into the hearth for combustion. The high-temperature flue gas generated during combustion heats the water inside the water tank, and finally the flue gas is discharged outside the furnace. However, this traditional coal stove has many defects in use:

[0004] First, the existing coal stove usually directly sends agricultural and forestry wastes and combustible coal into the hearth for combustion, lacking mixing and crushing treatment of the two fuels. The physical and chemical properties of agricultural and forestry wastes and combustible coal differ greatly, and direct mixing and combustion can easily lead to incomplete combustion of agricultural and forestry wastes, producing a large number of unburned particles. At the same time, the combustion efficiency of large-volume agricultural and forestry wastes and combustible coal is relatively low, which not only wastes energy but also increases the risk of environmental pollution.

[0005] Secondly, the existing coal stove also has deficiencies in flue gas treatment. After the flue gas heats the water inside the water tank, it is usually directly discharged into the atmosphere, and cannot be used to dry agricultural and forestry wastes and combustible coal.

[0006] Therefore, it is necessary to invent an environmentally friendly and energy-saving coal stove. UTILITY MODEL CONTENT
