Embodiment 1

[0038] See Figure 1-2 , 4-8, 10-11, in the figure (the direction of the arrow indicates the flow of flue gas), the civil coal-fired heating stove of the present invention includes a furnace shell 1 and a top cover 2. The lower part of the sealed chamber formed by the furnace shell is Furnace 3, a grate 4 is provided in the furnace, the middle of the top cover is provided with a coal filling port, and the upper part of the sealed chamber is provided with box-shaped inner and outer water jackets 5, 6 with open lower ends, wherein the top of the inner water jacket To be lower than the top of the outer water jacket, one side of the inner and outer water jackets is connected by a pipe 7. The tops of the inner and outer water jackets are provided with through holes 8, 9 respectively at the coal filling openings, and the lower end of the inner water jacket is fixed to the furnace On the bent frame, the top of the outer water jacket is fixed on the bottom surface of the top cover, the ...

Embodiment 2

[0041] See Figure 5-11 The structure of this embodiment is similar to that of the first embodiment, and the same parts will not be repeated here. The difference is that: the inner wall of the housing described in this embodiment is provided with a heat insulation layer 15. A heat preservation channel 16 is provided between the shell and the heat insulation layer, and the width of the heat preservation channel is 25 mm.

[0042] Compared with the first embodiment, this embodiment can avoid the loss of heat generated by combustion as much as possible during use, and improve the heat utilization rate; moreover, in this way, no matter how the boiler is burned, the outer wall is cool to the touch, which also ensures It is safe to use and prevents children from being burned by accidentally touching the furnace body.

Embodiment 3

[0044] See figure 2 , 5 , 9, 11-12, the structure of this embodiment is similar to the first embodiment, and the same parts will not be repeated here. The difference is: in this embodiment, there is provided between the rear side of the outer water jacket and the furnace shell The smoke exhaust channel 17 has a smoke exhaust port on the top cover corresponding to the smoke exhaust channel. A blocking cover 18 is provided in the smoke exhaust port, two sides of the blocking cover are pivotally hinged on the smoke exhaust port, and a rotating handle 19 is provided on one side of the blocking cover.

[0045] This embodiment is compared with the first embodiment. When in use, because the smoke exhaust channel is set between the rear side of the outer water jacket and the furnace shell, the smoke will be reheated by the outer water jacket through the coal fire secondary circulation channel. The residual heat contained in the gas is already very small, and the exhausted smoke is almos...

Abstract

The invention belongs to the technical field of heating appliances and particularly relates to a civilian coal-fired heating stove. The civilian coal-fired heating stove comprises a stove body casing and a top cover, wherein the lower portion of the inside of a sealed cavity defined by the stove body casing is a hearth, a fire grate is arranged in the hearth, a coal feeding opening is formed in the middle of the top cover, at least two layers of box-shaped inner and outer water jackets with open lower ends are arranged at the upper portion of the inside of the sealed cavity, the tops of the inner water jackets are lower than the tops of the outer water jackets, and one side of each inner water jacket is communicated with one side of each outer water jacket through a pipe. Through holes are formed in the positions, corresponding to the coal feeding opening, of the tops of the inner and outer water jackets respectively, the lower ends of the inner water jackets are fixed to a fire grate frame, the tops of the outer water jackets are fixed to the bottom face of the top cover, central flame paths are formed at the central positions of the inner water jackets, a coal fire secondary circulation channel is formed between the inner water jackets and the outer water jackets, two water outlet pipes are symmetrically arranged at two ends of the rear side of the top cover and communicated with the tops of the outer water jackets, and two water inlet pipes are symmetrically arranged at the lower portions of the inner water jackets and penetrate through the back side of the stove body casing. The civilian coal-fired heating stove is full in heat exchange, high in heating efficiency, ideal in room temperature effect and convenient to operate and use, coal resources are saved, and the heating expenditure is saved.

Description

Technical field [0001] The invention belongs to the technical field of heating appliances, and particularly relates to a civil coal-fired heating stove. Background technique [0002] Nowadays, there are still large areas of rural areas and areas in China that have not achieved central heating, and they are still using heating stoves to heat through the severe winter. Over the years, many manufacturers have continuously improved civilian coal-fired heating stoves, but there are still many problems, such as low efficiency, insufficient heat exchange, coal consumption, and large heating expenses. In order to save coal resources, save heating expenses, protect the ecological environment, and reduce pollution, this heating stove is specially developed. Summary of the invention [0003] The technical problem to be solved by the present invention is to overcome the above-mentioned shortcomings of the prior art, and provide a civil coal-fired heating stove with reasonable structure, suff...
