Abstract
The utility model discloses a heating furnace which comprises a furnace shell and a flue, wherein the furnace shell is internally provided with a furnace mouth, a hearth, a grate and an ash storage chamber in sequence from top to bottom, wherein the top of the furnace shell, i.e., the periphery of the furnace mouth, is provided with an upper water jacket; the upper water jacket and a water jacket of the hearth form an integrated structure; a plurality of downwards-extending communication pipes are arranged on a position on the bottom wall of the upper water jacket, close to the furnace mouth; and the communication pipes are communicated with the lower part of the water jacket of the hearth. Through the additional arrangement of the upper water jacket, the radiation heat exchange area of a high-temperature region above the hearth is increased, and the heat exchange efficiency is increased; in addition, the upper water jacket is not only communicated with the upper part of the water jacket of the hearth, but also communicated with the lower part of the water jacket of the hearth through the communication pipes, so that water at the lower part inside the water jacket of the hearth sufficiently absorbs heat to further increase the heat exchange efficiency, and then, a coal-saving effect is achieved and the heating cost is reduced.

Technical field
The utility model 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 the furnace shell, is provided with water jacket between furnace shell and the burner hearth; Water jacket is the identical cylindrical water jacket of diameter up and down, and water jacket heating surface area up and down is consistent, causes high-temperature region, burner hearth top radiation heat transfer area little; Heat exchange efficiency is low, has increased the heating cost.
Summary of the invention
Thereby the technical problem that the utility model will solve provides a kind of economizing on coal reduces the heating stove of heating cost.
For solving the problems of the technologies described above, the utility model comprises furnace shell and flue, and furnace shell inside is provided with fire door, burner hearth, fire grate, ash storing chamber from top to bottom successively; Ash storing chamber one side is provided with opening, and furnace shell is provided with can be with the air door of the closure of openings of ash storing chamber, and burner hearth is communicated with flue; Be provided with hearth water sleeve between furnace shell and the burner hearth; Hearth water sleeve is provided with water inlet pipe and outlet pipe, and its design feature is that the fire door periphery of said furnace shell is provided with upper water sleeve, and upper water sleeve and hearth water sleeve are into a single integrated structure; And the upper water sleeve diapire is being provided with the communicating pipe of stretching under many near the fire door place, and communicating pipe is communicated with the hearth water sleeve bottom.
After adopting said structure, through setting up upper water sleeve, high-temperature region, burner hearth top radiation heat transfer area increases; Heat exchange efficiency is improved, and upper water sleeve not only is communicated with hearth water sleeve top, also through being communicated with the hearth water sleeve bottom communicating pipe; The water of bottom in the hearth water sleeve is fully absorbed heat; Further improve heat exchange efficiency, thereby reach effect of coal saving, reduce the heating cost.
Said communicating pipe is 6, is provided with along the burner hearth periphery, guarantees the fully heat exchange of water of bottom in the hearth water sleeve, improves heat exchange efficiency.
Said flue is provided with the flue water jacket, and the flue water jacket is communicated with hearth water sleeve, and outlet pipe is arranged on flue water jacket top, makes full use of the heat of flue gas, reduces the consumption of coal.
Said inboard wall of burner hearth is built has refractory material furnace lining, and furnace lining top and upper water sleeve keep at a certain distance away, and the height that furnace lining is provided with, heating stove heat up slow but cooling is also slow; It is low that furnace lining is provided with, and heating stove quick heating still cooling is also fast, so can be according to the design height of actual conditions choose reasonable furnace lining.
The outside of said furnace shell is provided with shakes grey bar, shakes grey bar and is connected with fire grate, is provided with the gripper shoe that is used to support furnace lining between furnace shell internal furnace and the fire grate, the convenient ashes of removing on the fire grate.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further explain:
Fig. 1 is the structural representation of the utility model;
The sketch map that Fig. 2 analyses and observe along the A-A line for Fig. 1;
Fig. 3 is the another kind of embodiment of flue.
The specific embodiment
Extremely shown in Figure 3 like Fig. 1; Heating stove comprises furnace shell 1 and flue 2; Furnace shell 1 inside is provided with fire door 3, burner hearth 4, gripper shoe 5, fire grate 6, ash storing chamber 7 from top to bottom successively, and ash storing chamber 7 is provided with opening, and the ashes after the burning drop to ash storing chamber 7 and remove ashes from opening from fire grate 6; Furnace shell 1 is provided with can be with the air door 8 of the closure of openings of ash storing chamber 7, through the duration and degree of heating of control air door 8 openings of sizes control heating stove.Burner hearth 4 is communicated with flue 2, is provided with hearth water sleeve 9 between furnace shell 1 and the burner hearth 4, and flue 2 is provided with flue water jacket 16; Flue water jacket 16 is communicated with hearth water sleeve 9, and hearth water sleeve 8 bottoms are provided with water inlet pipe 10, and flue water jacket 16 tops are provided with outlet pipe 11; The heat that water jacket can make full use of flue gas also is set on flue 2; Reduce the consumption of coal, flue 2 can use straight pipe type also can use bent-tube boiler, and the bent-tube boiler flue can be symmetrical set two outlet pipes 11 above it to improve the heat exchange effect.Be provided with in the outside of furnace shell 1 and shake grey bar 13, shake grey bar 13 and be connected, make the ashes on the fire grate 6 fall ash storing chamber 7 through shaking grey bar 13 with fire grate 6.Furnace shell 1 top is that fire door 4 peripheries are provided with upper water sleeve 14, and upper water sleeve 14 is into a single integrated structure with hearth water sleeve 9, and upper water sleeve 14 diapires are establishing the communicating pipe 15 of stretching under 6 near fire door 4 place's uniform ring, and communicating pipe 15 is communicated with hearth water sleeve 9 bottoms.Burner hearth 4 inwalls are built has refractory material furnace lining 12; Gripper shoe 5 supports furnace lining 12; The diameter of a circle that the internal diameter of furnace lining 12 surrounded into less than all communicating pipes 15 is that furnace lining 12 coats communicating pipe 15; Furnace lining 12 tops and upper water sleeve 14 keep at a certain distance away, and the height that furnace lining 12 is provided with, heating stove heat up slow but cooling is also slow; It is low that furnace lining 12 is provided with, and heating stove quick heating still cooling is also fast, so can be according to the design height of actual conditions choose reasonable furnace lining.
