Abstract
The invention discloses a spiral-flow type combustion furnace. The spiral-flow type combustion furnace comprises a furnace body; the bottom wall of the furnace body is provided with an air inlet; the air inlet is connected with an air blower via an air charging pipe; the combustion furnace is characterized in that a partition plate is arranged inside the furnace body and is used for dividing the inner chamber of the furnace body into an air chamber and an combustion chamber; the air chamber is positioned between the partition plate and the bottom wall of the furnace body; the partition plate is connected with a burner nozzle which is connected with an oil pipe; the oil pipe is connected with an oil nozzle in the sidewall of the furnace body; the partition plate is also provided with a plurality of air outlets; the air outlets are arranged clockwise; the included angle between each air outlet and the partition plate is 30 to 50 degrees. By utilizing spiral-flow type combustion and lengthening the combustion chamber, the combustion furnace disclosed by the invention has the advantages of prolonging the flame rise time, prolonging the heating time and improving the thermal efficiency.
Description
Technical field
The present invention relates to a kind of combustion furnace, specifically a kind of spiral-flow 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 air blast 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, air blast 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.Air blast passes through air blast 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 air effect, owing to the air of this combustion furnace is streamlined flow, connect with fuel
Contacting surface is amassed little, and again almost without combustion chamber, fuel is short with the air contact time, causes fuel combustion abundant not, energy
Amount conversion ratio is low.
Summary of the invention
In order to solve the problem that prior art exists, the present invention provides a kind of spiral-flow type combustion furnace, and this spiral-flow type combustion furnace utilizes
Air swirl heats, and makes fuel combustion more abundant, improves capacity usage ratio.
The present invention adopts the following technical scheme that spiral-flow type combustion furnace, including body of heater, the diapire of body of heater has air inlet, enters
Air port is connected with air blast by blast pipe, it is characterised in that: have dividing plate in body of heater, dividing plate body of heater inner chamber is divided into air compartment with
Combustion chamber, air compartment, between dividing plate and body of heater diapire, dividing plate connects and has burner, burner to be connected with oil pipe, oil pipe
Being connected with the oil nozzle on sidewall of the furnace body, dividing plate also has several air outlets, described air outlet is arranged clockwise, air-out
Mouth and dividing plate angle are 30～50 °.
During use, the air that air blast is sent enters air compartment from blast pipe, then enters combustion chamber through air outlet, fluid (or combustion
Gas) enter oil pipe from oil nozzle, subsequently into burner, burn under air effect, owing to air outlet is to tilt, so
Air, when blowing out from air outlet, can blow on the sidewall of combustion chamber, then be burned room sidewall and stop and turn back, and so circulates,
Form eddy flow, promote flame also to become cyclonic flame, simultaneously because extend combustion chamber, extend the time that flame rises, increase
Add heated time, improve the thermal efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing combustion furnace.
Fig. 2 is the schematic diagram of the spiral-flow type combustion furnace of one embodiment of the invention.
Fig. 3 is the schematic diagram of the dividing plate of the spiral-flow type combustion furnace of one embodiment of the invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings embodiments of the invention are described specifically:
Spiral-flow type combustion furnace, as in figure 2 it is shown, include body of heater 22, the diapire of body of heater 22 has air inlet, and air inlet leads to
Crossing blast pipe 21 to be connected with air blast, have dividing plate 25 in body of heater 22, body of heater 22 inner chamber is divided into air compartment 26 He by dividing plate 25
Combustion chamber 28, air compartment 26, between dividing plate 25 and body of heater 22 diapire, dividing plate 25 connects and has three burners 24,
Burner 24 is connected with oil pipe 23, and oil pipe 23 is connected with the oil nozzle 27 on body of heater 22 sidewall, and dividing plate 25 also has six
Individual air outlet 29, air outlet 29 is centered around around burner 24, and described air outlet 29 is arranged clockwise, air outlet 29
It it is 45 ° with the angle of dividing plate 25, as shown in Figure 3.
The foregoing is only a kind of optimum embodiment of the present invention, not limitation of the present invention, every utilize the present invention's
The equivalent transformation that mentality of designing and principle are made, or directly or indirectly it is used in other relevant technical fields, the most in like manner include
In the scope of patent protection of the present invention.
