Abstract
The utility model relates to a waste heat utilization device of a combustion furnace. The waste heat utilization device comprises a front-end furnace body (1a), a middle furnace body (1b) and a rear-end furnace body (1c). A combustor (2) is connected to the front-end furnace body (1a), and the combustor (2) is connected with a combustion air fan (3) and gas (8) respectively. Each furnace body on the front side of the rear-end furnace body is connected with a cooling tower (4) through a water inlet pipe (6) and a water returning pipe (7). The waste heat utilization device of the combustion furnace is characterized in that the rear-end furnace body is connected with the combustion air fan (3) through a combustion air pipe (5), and the rear-end furnace body is further connected with the combustor (2) through the combustion air pipe (5). The waste heat utilization device of the combustion furnace has the advantages that the waste heat utilization device can be used on a small combustion furnace, the structure is simple, design is reasonable, waste heat of the combustion furnace is mainly used for heating combustion air, and therefore the combustion efficiency is improved and production cost is reduced.
Description
Technical field
The utility model relates to a kind of combustion furnace, particularly a kind of combustion furnace residual heat using device.
Background technology
Existing combustion furnace is of a great variety, and residual-heat utilization method is also respectively to have feature.Because the waste heat of Small Combustion stove is not very large, its utilization is not taken seriously, and when at long time integration in the situation that, Small Combustion stove also can produce a large amount of waste heats, because it is ignored, so cause the waste of many heats, is virtually improving production cost.Through extensively retrieval, not yet find comparatively desirable technical scheme.
Utility model content
The purpose of this utility model is in order to solve the present stage shortcoming that is not used appropriately of the waste heat that produces of Small Combustion stove, and a kind of combustion furnace residual heat using device proposing.
To achieve these goals, the utility model has adopted following technical scheme:
A kind of combustion furnace residual heat using device, comprise one group of body of heater, body of heater comprises front end body of heater, middle body of heater and rear end body of heater, on front end body of heater, connect burner, burner connects respectively combustion fan and combustion gas, on each body of heater of body of heater front side, rear end, be all connected cooling tower by water inlet pipe with return pipe, it is characterized in that: described rear end body of heater connects combustion fan by combustion-supporting airduct, rear end body of heater also connects burner by combustion-supporting airduct.
Original combustion furnace is that burner passes through combustion-supporting airduct and is directly connected with combustion fan, and each body of heater is connected cooling tower with return pipe by water inlet pipe, utilize cooling tower to think that each body of heater provides the cooling water of circulation, body of heater is cooling, due to the body of heater of final section from burner flame away from, and the material of body of heater is stainless steel, through constantly experiment, this joint body of heater can not add chilled water unit, the utility model is connected to final section body of heater by combustion air pipeline exactly, utilize the heat preheated-combustion-supporting wind of this joint body of heater, after preheating, combustion air temperature reaches 60 DEG C of left and right, when after combustion air and the contacts fuel gas of lighting, combustion gas is fully burnt, thereby improve efficiency of combustion.
The utility model has the advantage of: this device can use on Small Combustion stove, and it is simple in structure, reasonable in design, it is mainly to utilize the waste heat of combustion furnace to heat combustion air, thereby improves efficiency of combustion, reduces production costs.
Brief description of the drawings
Fig. 1 is basic structure schematic diagram of the present utility model.
Detailed description of the invention
As shown in Figure 1, a kind of combustion furnace residual heat using device that the utility model provides, comprise three joint bodies of heater 1, body of heater 1 comprises front end body of heater 1a, middle body of heater 1b and rear end body of heater 1c, on front end body of heater 1a, connect burner 2, burner 2 connects respectively combustion fan 3 and combustion gas 8, front end body of heater 1a is all connected cooling tower 4 by water inlet pipe 6 with return pipe 7 with middle body of heater 1b, it is characterized in that: described rear end body of heater 1c connects combustion fan 3 by combustion-supporting airduct 5, rear end body of heater 1c also connects burner 2 by combustion-supporting airduct 5, combustion air has combustion-supporting airduct 5 to pass into burner 2 after rear end body of heater 1c heating.
Claims (1)
