Abstract

The utility model discloses an energy saving heat producing and supplying stove. A hot coal heating device (2) composed of an upper header (7), a water pipe (10) and a lower header (12) is adopted for leading the firing smoke inside the stove to enter a smoke channel (14) in a smoke channel device (1) arranged outside the stove from an inlet (15), and than the firing smoke enter an upper smoke channel from an inlet (24). Moreover, the firing smoke enters an upper and the lower smoke channel communicating pipe and enter a lower smoke channel. Finally, the firing smoke is collected by a chimney (23) and discharged into atmosphere. Thus, the heating area of the hot coal heating device (2) is expanded in multiples and is in the external combustion status with a plurality of heated surfaces. The utility model has the advantages of high heating efficiency, quick hot coal heating, high hot coal temperature and energy saving.

Description

Open fire back-smoke type household air heating stove with coal heater

The utility model belongs to domestic briquet stove heating field, and what relate generally to is the domestic heating stove of the long-pending and flue gas heat energy utilization of a kind of extended surface.

At present, its heating agent heater of existing domestic heating heating stove is still continued to use the water sleeve type structure, is heated because it is confined to one side, so its heat energy utilization is low, thermal waste is big.Some ironwares like fin are long-pending with extended surface though development is in the recent period burn-on on the top of water jacket inwall, and the heat energy utilization of flue gas also is heated because of one side and is restricted.

The purpose of this utility model promptly produces thus, proposes a kind of heating agent device external combustion back-smoke type domestic heating stove, and it is the heat energy utilization of the long-pending and flue gas of extended surface effectively, thereby has saved fire coal, has improved the thermal efficiency.

For achieving the above object, the utility model is achieved through the following technical solutions, the heating agent heater that it mainly is made up of upper header, water pipe and lower collecting box, led the flue device formation that cigarette ring flat-plate and upper, middle and lower flue, last lower flue communicating pipe and chimney are formed, upper header and lower collecting box are independently water tank, by water pipe (several) it is communicated as one therebetween, the water pipe section is provided with and leads the cigarette ring flat-plate between upper header bottom and lower collecting box top, has outlet flue at the corresponding site of this plate; Flue in the flue device is divided into three flues in upper, middle and lower, the smoke inlet that enters upper flue is left on top in middle flue one side, the opposite side relative with it is provided with upper and lower flue communicating pipe, a side relative with lower flue smoke inlet place is provided with chimney, forms the enforceable circuitous discharge of flue gas system.

The utility model reasonable in design, improve the heating agent heater that becomes upper header, water pipe and lower collecting box structure owing to will have the heating agent heater of water sleeve type, thereby expanded the heating surface area in the water jacket outside exponentially, flue gas also transfers enforceable circuitous discharge in flue device to by existing direct discharge, increase the follow row of flue gas in flue and reached 1.4 meters, along with the expansion of heating surface area and make full use of the heat energy of flue gas, thermal efficiency height, heating agent quick heating have correspondingly been produced, heat medium temperature is high and save coal-fired effect.

The utility model has the following drawings:

Accompanying drawing 1 is the utility model profile.

Accompanying drawing 2 is the utility model portfire schematic diagram.

Accompanying drawing 3 is the utility model banking fire tube, lid schematic diagram.

It is as follows to provide embodiment of the present utility model in conjunction with the accompanying drawings:

As shown in Figure 1: the utility model is mainly led the outer girth sheets (25) of cigarette ring flat-plate (26) stove by ash-pit (18) heating agent heater (2) flue device (1) and is constituted main body, heating agent heater (2) is made up of upper header (7) water pipe (10) lower collecting box (12), water pipe and last, lower collecting box adopts and is welded to connect, be positioned at the ash-pit top at stove center, flue device (1) is by on flue (14) lower flue (16) in the upper flue (8), lower flue communicating pipe and chimney (23) are formed, be positioned at the outside of heating agent heater (2), leading cigarette ring flat-plate (26) has exhanst gas outlet (15) and is positioned at water pipe section between stove center upper header (7) bottom and lower collecting box (12) top, stove peripheral board (25) has the outlet of chimney (23), being positioned at the flue device outside is seated at ash-pit top and is connected to form integral body with bolt, the course of work of the present utility model is as follows: the direct interior plate of heating upper header (7) interior plate and lower collecting box (12) in burner hearth of the aflame flame of coal cinder (17) (flue gas) in the burner hearth, the flame in burner hearth (flue gas) rise to that roof of the furnace is run into pressing plate or kettle (4) flue gas enters flue device (1) from two aspects: the one, and make progress or directly enter flue main-inlet (15) (be positioned at and lead the breach that cigarette ring flat-plate (26) is opened); The 2nd, enter time flue entrance place (3), the main effect of this inlet is that the flue gas that will be trapped in roof of the furnace enters the upper flue discharge, the flue gas that enters middle flue (14) by flue gas main-inlet place (15) left, right directly heating eight water pipes (10) that go in ring, upper header (7) bottom circumferential lamella, lower collecting box (12) apical ring plate, flue gas goes in ring and enters upper flue (8) left to the smoke inlet place (24) of upper flue (8), the right directly outer panel of heating upper header (7) that goes in ring, flue gas goes in ring and enters to upper flue (8) exit (9) subsequently, the porch (11) that enters lower flue (16) lower flue communicating pipe left, the right directly outer panel of heating lower collecting box (12) that goes in ring, be included into chimney (23) exit (22) then and enter atmosphere, for ease of the cleaning dust deposit in furnace, can take off the movable flue in cigarette ring flat-plate (26) cleaning of leading, also can open the cleaning door pressing plate cleaning lower flue of stove peripheral board (25) and flue device (1) lower flue (16).

As shown in Figure 2: when needs are cooked, take off the stove that gland or kettle (4) are put into portfire (6) in burner hearth On, can add that also one or two lump coal get final product, portfire has combustion-supporting effect.

As shown in Figure 3, bank up a fire or suppress fire, do not put the banking fire tube in the short stove of time, adjustable banking fire lid (5) directly can be put on the coal cinder of stove, put into banking fire tube (20) in the bank-up fire furnace overnight and add and put adjustable banking fire again behind two lump coal and cover (5) when needs.
