Abstract
The utility model discloses a heating furnace which comprises a furnace shell and a flue. A furnace opening, a hearth, a fire grate and an ash storage chamber are arranged in the furnace shell from top to bottom. The hearth is communicated with the flue. A hearth water sleeve is arranged between the furnace shell and the hearth. A water inlet pipe and a water outlet pipe are arranged on the hearth water sleeve. The hearth is in a big-end-up frustum shape. The furnace shell is in a big-end-up frustum shape. Due to the fact that temperature of outer flame is highest during coal combustion, the hearth is in a frustum shape, the furnace shell is in a frustum shape, water on the upper portion in the hearth water sleeve can be completely heated by the outer flame, water temperature is raised quickly and is high, heating can be better achieved, and meanwhile the effect of coal saving can be achieved, and heating cost is lowered.
Description
Technical field
The present invention relates to a kind of heating stove.
Background technology
Coal heating stove economy is material benefit again, is widely used in not having the rurbania of central heating condition and vast rural area.Present heating stove comprises furnace shell, is provided with burner hearth in furnace shell, is provided with water jacket between furnace shell and burner hearth, and the burner hearth up and down is isometrical, and water jacket is also the isometrical cylindrical water jacket in up and down, and it is slow that the water heat exchange efficiency in this kind structure water jacket is not high, water heats up, and the heating cost is higher.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of heating stove that can reduce the heating cost.
For solving the problems of the technologies described above, the present invention includes furnace shell and flue, furnace shell inside is provided with fire door, burner hearth, fire grate, ash storing chamber from top to bottom successively, burner hearth is communicated with flue, be provided with hearth water sleeve between furnace shell and burner hearth, hearth water sleeve is provided with water inlet pipe and outlet pipe, and described burner hearth is lower large little frustum, and furnace shell also is lower large little frustum.
After adopting said structure, during due to coal combustion, the temperature of flame envelope is the highest, burner hearth is frustum, furnace shell also is frustum, and the water of hearth water sleeve internal upper part can be heated by flame envelope fully like this, and the water programming rate is fast, water temperature is higher, can better warm oneself, can reach effect of coal saving simultaneously, reduce the heating cost.
The angle of described burner hearth sidewall and horizontal plane is 75 °, and the water programming rate in this kind structure hearth water sleeve is very fast.
Described flue is bent-tube boiler, and described flue is provided with water jacket of flue, and water jacket of flue is communicated with hearth water sleeve, and outlet pipe is arranged on the top of water jacket of flue, and the inwall of the vertical pipeline of flue is provided with the polylith deflection plate.Water jacket of flue is set on flue, and on the inwall of the vertical pipeline of flue, the polylith deflection plate is set, can allow high-temperature flue gas in flue fully with water jacket of flue in the water heat exchange, thereby reach effect of coal saving, reduction heating cost.
Be evenly equipped with the ash-falling hole that diameter is 1cm on described fire grate, prevent that the insufficiently burnt coal cinder of bulk from dropping, and fully burns coal.
Description of drawings
Below in conjunction with the drawings and the specific embodiments, the present invention is described in further detail:
Fig. 1 is structural representation of the present invention.
The specific embodiment
as shown in Figure 1, heating stove comprises furnace shell 1 and flue 2, furnace shell 1 inside is provided with fire door 3 from top to bottom successively, burner hearth 4, fire grate 5, ash storing chamber 6, burner hearth 4 tops are communicated with flue 2, be provided with hearth water sleeve 8 between furnace shell 1 and burner hearth sidewall 7, hearth water sleeve 8 bottoms are provided with water inlet pipe 9, flue 2 is bent-tube boiler, flue 2 is provided with water jacket of flue 11, water jacket of flue 11 is communicated with hearth water sleeve 8, outlet pipe 10 is arranged on the top of water jacket of flue 10, the inwall of the vertical pipeline of flue 2 is provided with three deflection plates 12 from top to bottom, the width of deflection plate 12 is 4/5ths of flue 2 internal diameters.Water jacket of flue 11 is set on flue 2, and on the inwall of the vertical pipeline of flue 2, polylith deflection plate 12 is set, can allow high-temperature flue gas flue 2 interior fully with water jacket of flue 11 in the water heat exchange, thereby reach effect of coal saving, reduction heating cost.Being evenly equipped with diameter on fire grate 5 is the ash-falling hole 13 of 1cm, prevents that the insufficiently burnt coal cinder of bulk from dropping, and fully burns coal.
Burner hearth 4 is lower large little frustum, and furnace shell 1 also is lower large little frustum, and burner hearth sidewall 7 is identical with the angle of inclination of furnace shell 1, and the angle of both and horizontal plane is 75 °.During due to coal combustion, the temperature of flame envelope is the highest, and burner hearth 4 is frustum, and furnace shell 1 also is frustum, the water of hearth water sleeve 8 internal upper parts can be heated by flame envelope fully like this, and the water programming rate is fast, and water temperature is higher, can better warm oneself, can reach effect of coal saving simultaneously, reduce the heating cost.
