Description

High efficiency stove for heat supply

The utility model relates to a kind of home furnace, specifically a kind of heating, cooking multipurpose furnace.

Present all kinds of patent heating stove has many forms, and a kind of structure preferably is to be surrounded by water jacket outside burner hearth, and return pipe passes furnace shell and is communicated with water jacket, and outlet pipe is communicated with water jacket and chimney water sleeve, and lower furnace portion is provided with fire grate, air door and ash bucket.Owing to be added with chimney water sleeve, many one exchange of reheating is so increase the thermal efficiency of this type of stove and accessory.But in actual use, as with the radiator more than four groups the time, it is painstaking that this type of stove just shows, the one, and coal consumption strengthens, and another is that the heating-up temperature of radiator just reduces.

The purpose of this utility model just provides a kind of Heating stove that relies on multiple heat to exchange to improve the thermal efficiency, to satisfy the actual needs that use.

The utility model is achieved in that at this type of hearth water sleeve and adds on the stove and accessory basis of chimney water jacket, the steam generator of packing on hearth water sleeve top, the steam outlet pipe that joins with generator passes furnace shell and enters chimney water sleeve, join with return tube again, return tube enters water jacket, be wound into the water jacket bottom, and lead to the jetted hole on the hearth wall.Owing in two water jackets, all there is the steam pipe of heat to pass through, increased by twice heat exchange, the outlet temperature of recirculated water is increased.The steam that feeds at last in addition in the burner hearth is met thermal decomposition, also plays combustion-supporting effect, and combustion temperature in hearth is raise, and has both improved the thermal efficiency, further makes the recirculated water heat temperature raising in two water jackets simultaneously again, thereby reaches the purpose that satisfies practical needs.

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is a surface structure schematic diagram of the present utility model.

As shown in Figure 1 and Figure 2, the top of body of heater connects chimney water sleeve 5, and the interior water jacket of outlet pipe 4 and return pipe 2 and furnace shell is communicated with, and outlet pipe also is communicated with chimney water sleeve 5.Steam outlet pipe 9 joins with return tube 10 at an upper portion thereof through behind the chimney water sleeve.In body of heater, steam generator 8 is equipped with on the top of water jacket 1 of cladding burner hearth, and its structure is that the end face at a toroidal shell has a plurality of inclined tubes and standpipe, and there is a ring tube that is communicated with all inclined tubes and standpipe inclined tube and standpipe intersection, and steam outlet pipe 9 is communicated with toroidal shell.Because this steam generator is positioned at the fire door place, heating-up temperature is the highest, makes the water vapor evaporation.Return tube 10 passes furnace shell 3 sidewalls and water jacket wall enters water jacket 1, and in water jacket coiled coil, the recirculated water in the water jacket is heated once more.Return tube is around connecting communicating pipe to water jacket bottom back, and communicating pipe communicates with jetted hole 12 around burner hearth sidewall, makes steam finally spray in the burner hearth combustion-supporting 24 by jetted hole.In lower furnace portion fire grate 6, air door 11 and ash bucket 7 are arranged.Bottom of furnace body is located by the leg three-point support.

For further improving the efficiency of combustion of stove and accessory and utilizing the distinctive steam power of this stove and accessory, also installed the automatic Blast mechanism of steamturbine additional in the body of heater bottom.It is combustion-supporting promptly to promote the blade air blast with steam.Its concrete structure is to be connected to threeway 13 on return pipe 10, is communicated with bypass steam pipe 14.The fire grate bottom in the burner hearth is led in bypass steam pipe 14 bottoms, and socket axle sleeve 16, and axle sleeve is fixed on by bearing 17 in the bearing block 18 that joins with furnace shell 3, and axle sleeve 16 ends connect fan blade 15 and have the oblique side opening that points to fan blade.Steam sprays from oblique side opening, drives the fan blade rotation to burner hearth air blast and steam, makes burning more abundant.

Chimney water sleeve 5 sides of being of this stove and accessory are barrel-shaped among Fig. 1, and its sidewall connects water inlet pipe 19 and conduit 20, and conduit 20 other ends connect steam generator 8, for steam generator provides the water source.On water inlet pipe, also can install the water level meter additional, so that safe indication to be provided.

For preventing in the stove and accessory use, flue gas is to people's infringement, the bell 21 that hides on the burner hearth made be the round box shape shape, and its bottom surface has sieve aperture, and 815 cleansers are equipped with in inside, so that flue gas is discharged through disinfecting the back.

Also accompanying asbestos heat-insulation layer 22 between furnace shell and water jacket, is vermiculite heat-insulation layer 23 in the furnace shell of lower furnace portion, thus body of heater further is incubated, and prevents that heat scatters and disappears, and improves recirculated water water temperature in the water jacket.

The utility model makes that by installing the automatic Blast mechanism of steam generator and steamturbine additional the recirculated water in hearth water sleeve and the chimney water sleeve has increased the heat exchange number of times, uses the saliva temperature and improves, and drives more groups of radiator operate as normal.Blast mechanism and burner hearth spray vapour system have all promoted burning, have improved the thermal efficiency.Sterilization mechanism makes the use of stove and accessory more safe and reliable.Under family expenses three times on the one cooking, the winter situation with four groups of radiator work, the temperature-averaging in four rooms is four blocks of standard cellular coals at 18 ℃ with coal through actual measurement, has realized energy-conservation, purpose efficiently.
