Description

High-efficiency cyclone superposing type combustion furnace

Technical field

This utility model relates to a kind of combustion furnace, specifically a kind of high-efficiency cyclone superposing type combustion furnace.

Background technology

The structure of existing heating furnace is as it is shown in figure 1, by the body of heater 12 of tubular, oil inlet pipe 13 (or air inlet pipe), burner 14 and aerator blast pipe 11 form, be provided with wind deflector 15 in body of heater 12, wind deflector 15 and body of heater 12 inwall surround air compartment 16, aerator blast pipe 11 communicates with air compartment 16, and burner 14 is located on wind deflector 15, burner 14 and oil inlet pipe 13 (or air inlet pipe) communicate, oil inlet pipe 13 (or air inlet pipe) and the oil-in 17 (or air inlet) on body of heater 12 outer wall Connect.Aerator passes through aerator blast pipe 11 air intake in air compartment 16, fuel oil (or combustion gas) by oil inlet pipe 13 (or Air inlet pipe) enter burner 14, burn under Cold air mass influence.Owing to this combustion furnace is to burn under Cold air mass influence, combustion Burning temperature is low, and cold air can take away again a part of heat, and energy consumption is big, and it is insufficient to burn.

Utility model content

In order to solve the problem that prior art exists, this utility model provides a kind of high-efficiency cyclone superposing type combustion furnace, this burning Stove utilizes air swirl, makes fuel combustion more abundant；Utilize superposing type to heat, improve furnace exit temperatures；By air Preheat, reduce the heat that cold air is taken away, greatly reduce energy consumption.

This utility model adopts the following technical scheme that high-efficiency cyclone superposing type combustion furnace, including external furnace body and body of heater, interior stove Body is enclosed within external furnace body, and body of heater has deep bead with the top of external furnace body, has between diapire and the diapire of external furnace body of body of heater Having dividing plate, dividing plate and external furnace body jointly to surround the first airtight air compartment, dividing plate, external furnace body, inner furnace body and deep bead enclose jointly Becoming the second airtight air compartment, be arranged with some guide ducts in the second air compartment, the outlet of guide duct is close but does not contact deep bead, The import of guide duct communicates with the first air compartment；Having air inlet on the diapire of external furnace body, air inlet passes through blast pipe and aerator Connect；Having single-stage combustion mouth on inner furnace body diapire, inner furnace body diapire has several one-level air outlets, one-level air outlet encloses It is wound on around single-stage combustion mouth；Have two grades of air outlets on inner furnace body sidewall, inner furnace body sidewall has several stepped The multistage combustion mouth arranged, single-stage combustion mouth and multistage combustion mouth be connected with the oil-out of oil pipe, the oil-in of oil pipe and outer stove Oil nozzle on body sidewall connects.

During use, the cold air (cold wind) that aerator is sent enters one-level air compartment from blast pipe, then enters two grades through guide duct Air compartment, owing to the outlet of guide duct is turned back through deep bead stop near deep bead, cold air, gone out from one-level air outlet or two grades Air port enters combustor, and fluid (or combustion gas) enters oil pipe from oil nozzle, subsequently into burner, fires under Cold air mass influence Burn；When, after heating a period of time, inner furnace body sidewall is also heated, and now, cold air is during reflux, with inner furnace body side Wall carries out heat exchange, makes cold air become hot-air, and enters combustor from the first air outlet or the second air outlet, participates in combustion Burn, the heat that the heat taken away due to hot-air is taken away well below cold air, make the effective temperature rising that burning produces；Again Person, inner furnace body sidewall has the multistage combustion mouth of arranged in step shape, when single-stage combustion mouth burns, can produce a theory Ignition temperature (identical with actual combustion temperature), preheats the air in combustor simultaneously；When secondary firing mouth fires During burning, owing to secondary firing mouth is in by the pre-warmed air ambient of single-stage combustion mouth, and the burning of secondary firing mouth also can be produced A raw theoretical temperature combustion, through superposition, the actual combustion temperature of secondary firing mouth is certainly higher than the reality of single-stage combustion mouth Ignition temperature；Equally, the actual combustion temperature of three grades of burners again can be higher than the actual combustion temperature of secondary firing mouth, the most often The actual combustion temperature of the burner of many one-levels is all higher than the actual combustion temperature of its previous stage burner, thus realizes temperature and fold Add, make the actual outlet temperature at furnace exit raise, meanwhile, the ring that the fluid (or combustion gas) of multistage combustion mouth burns Border temperature is higher, and burning is more abundant, and energy transformation ratio is high.

One-level air outlet is arranged clockwise, and one-level air outlet is 30～50 ° with the angle of inner furnace body diapire, two grades of air outlet edges Inner furnace body sidewall up time is arranged, between air outlet and inner furnace body sidewall, angle is 30～50 °.Owing to one-level air outlet and two grades go out Air port is all to tilt, so air (wind) is when from one-level air outlet or two grades of air outlet blowouts, can blow to inner furnace body On sidewall, then turned back by the stop of inner furnace body sidewall, so circulate, form eddy flow, promote flame also to become cyclonic flame, extend The time that flame rises, add heated time, improve the thermal efficiency.
