Novel fire coal stove

Abstract

The invention relates to a novel coal-fired furnace, belonging to the technical field of coal-fired furnace structure. The novel coal-fired furnace comprises a substrate at the bottom of the furnace body, wherein, the substrate is connected with a furnace cavity by a grate; and an outer bladder is arranged on the periphery of the furnace cavity. The novel coal-fired furnace is characterized in that a dust storage tank surrounds the lower part of the furnace body, and is provided with an exhaust port and a dust blowing port; the upper part of a combustion chamber is provided with a conical reflection chamber formed by a dust return cone at the side and a reflector board at the top; the reflection chamber is communicated with a water purifying bladder above the reflection chamber by a filter at the top of the reflection chamber; a plurality of heat pipes are arranged inside the water purifying bladder; a front chamber with a dust removal port at the top of the furnace body is separated from the upper part of the water purifying bladder by a front chamber board; a plurality of heaven and earth pipes are arranged between the front chamber and a water splint of the dust storage tank; aplurality of heat-transfer pipes surrounding the periphery of the combustion chamber are arranged in the outer bladder. The invention solves a plurality of defects of the existing coal-fired furnaces, has the advantages of reasonable structure, convenient operation, low energy consumption, high thermal efficiency, small volume, environmental protection, good operating environment and heat supply,and can simultaneously boil drinking water, thereby truly realizing the aims of safety, environmental protection, high efficiency, energy conservation and one furnace with multiple purposes.

Description

1. Technical field [0001] The invention relates to a coal-fired furnace, in particular to an energy-saving and environment-friendly coal-fired furnace, which belongs to the technical field of coal-fired furnace structure. 2. Background technology [0002] At present, the coal-fired furnace is mainly based on the sequential firing method. While the coal is burning in the furnace, it is necessary to use a smoke exhaust device to discharge the smoke and dust generated by the combustion, but the discharge of the smoke is accompanied by the loss of a large amount of heat energy. It not only pollutes the atmosphere, but also carries a large amount of combustible tiny coal particles. Coal-fired furnaces using the sequential firing method consume a lot of coal, have low thermal efficiency and pollute the environment. Although there are different improvement measures for the shortcomings of this type of coal-fired furnace, such as installing a dust removal device on the smoke exhaust...

AI Technical Summary

Problems solved by technology

Coal-fired furnaces using the sequential firing method consume a lot of coal, have low thermal efficiency and pollute the environment. Although there are different improvement measures for the shortcomings of this type of coal-fired furnace, such as installing a dust removal device on the smoke exhaust device, they have not been fundamentally overcome. Disadvantages of Shun firing method

Moreover, the existing coal-fired furnace is bulky because the furnace body has a smoke exhaust device, which makes installation difficult and inconvenient to move.

Because the furnace body of the existing coal-fired furnace is mostly not insulated, the heat flow in the furnace leaks out, and the coal consumption causes the operating environment of the boiler room to deteriorate, and the phenomenon of dizziness and burns of the operator often occurs
