The improved water heating stove is characterized in that a hot-blast main pipe is arranged at the outside of the stove liner; the upper end of the hot-blast main pipe is communicated with the upper part of a hearth; the lower end of the hot-blast main pipe is exposed at the outside of the outer shell of the stove body, and an adjusting wind cap is arranged on the outer shell of the stove body; a drop pipe is connected between the discharging pipe and the water inlet pipe of the water jacket. The utility model is mainly used for families to heat and has the advantages of sufficient combustion, high thermal efficiency, good water cycling performance, etc.

Description

Hot-blast combustion-supporting water furnace

The utility model relates to a kind of service water radiator of economizing on coal.

At present, the resident who does not realize collective's heating, no matter be city or rural area, mostly bring into use the service water radiator, this class warming stove is to adopt hot-water heating basically, in burner hearth water jacket is set and finishes, can realize the multiple function of cooking, heat up water, warm oneself, make things convenient for the user.From long-term operating position, there is the shortcoming of incomplete combustion in this class warming stove, not only wastes fuel, and causing indoor dirty malarial region gas, discharged flue gas has also been polluted atmospheric environment, therefore, a lot of people have also made a lot of improvement in this respect, as application number is 88219650, and name is called the patented technology of " endless tube twin flue hot-water heating stove ", adopts two upper flues to control burning, the utilization rate that improves coal has been obtained effect preferably, but, this furnace construction complexity, practical operation is wayward.

The purpose of this utility model is to provide a kind of service water radiator of improved sufficient combustion, and is simple in structure, easily control, and the cycle performance of water number.

The purpose of this utility model can realize in the following manner:

The combustion-supporting hot-water heating stove of hot blast, it is a kind of improvement service water radiator, mainly comprise stone or metal plate for standing a stove on as a precaution against fire, bell, body of heater shell, water jacket, furnace lining, grate, ash bucket, mouth, it is characterized in that there is a warm-air pipe in the furnace lining outside, the upper end of warm-air pipe passes to upper furnace, the lower end of warm-air pipe is exposed at the outside of body of heater shell, and the accent blast cap is arranged on it.

The purpose of this utility model can also realize by following scheme:

The combustion-supporting hot-water heating stove of described hot blast is characterized in that being associated with down-comer between the outlet pipe of water jacket and the water inlet pipe.

Upper and lower water jacket of the present utility model for well, certainly, also can be other shape, as square with circle.Tedge between the upper and lower water jacket can have 4～12, determines with the caloric value size of stove.

In addition, convenient for the manufacturing and the maintenance of stove, body of heater shell and whole combustion chamber are designed to two body structures, and suit connects.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1, cutaway view of the present utility model

Among the figure: 1 transfers blast cap, 2 to transfer wind adapter, 3 warm-air pipes, 4 upper water sleeves, 5 stone or metal plate for standing a stove on as a precaution against fire water jackets, 6 string water pipes, 7 outlet pipes, 8 down-comers, 9 tedges, 10 body of heater shells, 11 return pipes, 12 grates, 13 lower water jackets, 14 furnace linings.

Embodiment:

Stone or metal plate for standing a stove on as a precaution against fire water jacket 5 is in the top of stove, and its water jacket cavity communicates with upper water sleeve 4, is communicated by six roots of sensation tedge 9 between upper water sleeve 4 and the lower water jacket 13, and tedge 9 is close to the outer wall of furnace lining 14, is associated with down-comer 8 between outlet pipe 7 and the return pipe 11.Water is from return pipe 11 process lower water jacket 13 successively, tedge 9, upper water sleeve 4, string water pipe 6, stone or metal plate for standing a stove on as a precaution against fire water jacket 5, flow to outlet pipe 7, deliver to radiator then, wherein current heat successively through lower water jacket 13, tedge 9, upper water sleeve 4, string water pipe 6, stone or metal plate for standing a stove on as a precaution against fire water jacket 5, the current of outlet pipe 7 place's water temperature deficiencies continue heating from down-comer 8 to return pipe 11.

Hot-fluid airduct 3 is in the outside of furnace lining 14, and its upper end passes to upper furnace, and the lower end is by transferring wind to take over 2 outsides that are connected to body of heater shell 10, again with transfer the blast cap socket.By regulating blast cap 1, can control the flow of hot blast, thereby adjust combustion case.Grate 12 is positioned at the lower end of whole combustion chamber.

Leave corresponding hole on the body of heater shell of the present utility model, so that corresponding with the hot blast mouth of pipe and the backwater mouth of pipe on the whole combustion chamber, to realize that body of heater shell 10 and whole combustion chamber are two body structures, suit connects.

The utility model compared with prior art has the following advantages:

(1) stove in use, air enters burner hearth by grate, coal in the burner hearth is in combustion process, because the thermal decomposition effect produces free carbon, carbon black, hydrogen etc., some does not participate in burning, perhaps burn, but exist the intermediate products such as a part of co in the combustion product that generates, these combustibles together enter upper furnace, the hot-air of discharging with warm-air pipe meets (transfer blast cap 1 can regulating air volume), can burn away and emit heat, energy savings, reduce again the discharge of black smoke, alleviated the pollution to environment.

(2) Secondary Air is compared than cold air with hot blast, and preferably with the effect of flame, warm-air pipe is simple in structure, and combustion-supporting effect is good. The adjusting of hot blast rate is only regulated by the accent blast cap of warm-air pipe lower end and finished, and is easy to operate.

(3) the utility model has been set up down-comer in the water circulation pipe of stove inside, water can be in stove circulating-heating to sufficient temp, conserve energy, quick heating, and improved the water circulation performance of stove inside.

(4) body of heater shell and whole combustion chamber are two body structures, and suit connects, and it is all very convenient to make and keep in repair.

(5) characteristics of the technical program can be used in the large-scale stove, for a new approach has been opened up in the improvement of large-scale stove.
