The specific embodiment
Full premix combustion system to the utility model high efficient heat exchanging is described further below in conjunction with drawings and Examples.Shown in accompanying drawing 1,2, comprise housing 9, place the burner 5 in the housing 9 and the air that is connected with burner 5, the full pre-mixing apparatus 7 of combustion gas, sense flame device 4 and igniter 2, the full pre-mixing apparatus 7 of air, combustion gas constitutes burner 3 with burner 5.Burner 5 and housing 9 coaxial settings are provided with tubular heat exchanger 8 between them, the top and bottom of heat exchanger 8 are drawn water inlet 15 and delivery port 16 respectively.In housing 9, also be provided with upper seal 1, top capping 14, strain component 6, top thermal insulation barriers 13, bottom thermal insulation barriers 10, lower seal 11, bottom capping 12.Wherein heat exchanger 8 places cylindrical shell body 9 inboards, and pass its lower end and the upper end is drawn water inlet 15 and delivery port 16 respectively, burner 5 places heat exchanger 8 middle parts, upper seal 11 and top thermal insulation barriers 13 are pressed in heat exchanger 8 tops by top capping 14 and play sealing and heat-blocking action, lower seal 11 and bottom thermal insulation barriers 10 are pressed in efficient heat exchanger 8 bottoms by bottom envelope 12 and play sealing and heat-blocking action, and top capping 14 and bottom capping 12 are asked by three groups of strain components 6 fastening.In the technique scheme, heat exchanger 8 adopts monometallic aluminum alloy strip finned tube to spiral into the cylindrical screw shape, in more effective absorption obvious heat of smoke, also absorb part latent heat in the flue gas, thereby have higher heat exchange efficiency and have condensation effect, have the high corrosion resistance energy simultaneously; Cylindrical shell body 9 adopts the weldering of aluminum alloy plate materials volume to form, and has in light weight and decay resistance; Top thermal insulation barriers 13 and bottom thermal insulation barriers 10 adopt the ceramic fibre material compacting to form, and have well heat insulation and environment protecting.
Shown in accompanying drawing 1,3, air of the present utility model, the full pre-mixing apparatus of combustion gas comprise motor 71, wind wheel 72, mixed chamber 73, the air lead-in portion 74 that is provided with air intake, mixed gas outlet 76 and the fuel gas supply part 79 that is provided with fuel gas inlet 5, magnetic valve, metastable gas pressure device, gas quantity adjusting device, magnetic valve gas nozzle 10.Wind wheel 72 is installed in the hybrid chamber 73, and the output shaft of motor 71 and wind wheel 72 be coaxial to be connected or by being in transmission connection, hybrid chamber 73 is fixedly connected on the fuel gas supply part 79, and the bottom of hybrid chamber 3 is provided with the mixed gas outlet 76 of air and combustion gas.
The master controller (not shown) is according to inflow temperature, these three groups of data of leaving water temperature that discharge and user set calculate the thermic load size automatically and give the certain magnitude of voltage of motor 71 inputs (under certain thermic load the correspondent voltage value being arranged), motor 71 rotates with certain rotating speed under given magnitude of voltage, the wind wheel 72 that drives in the hybrid chamber 73 produces a certain amount of high-energy air air-flow with the rotating speed rotation of identical or a certain ratio, and this high-energy air air communication crosses that a certain amount of combustion gas of gas nozzle 70 injections enters that hybrid chamber 73 mixes fully after mixed air outlet 76 is sent in the burner 5 burns.The size of the gas quantity of injection is linear change with motor 71 (both wind wheel 72) change in rotational speed, can regulate burner thermic load size by control motor 71 rotating speeds easily.
As shown in Figure 4, burner of the present utility model is made up of burner outer ring 52, burner inner ring 53, guide sleeve 54, capping 51 and connecting flange 55 etc.Burner outer ring 52, burner inner ring 53 become cylindric butt welding to form by the plate circle, and they and guide sleeve 54 coaxial welding are on connecting flange 55, and capping simultaneously 51 is press-fitted the back welding with burner outer ring 52.Burner outer ring 52 along the circumferential direction is provided with the circular and waist shape fire hole 56 of some on certain-length, burner inner ring 53 along the circumferential direction is provided with some and divides pore 57 on certain-length.Combustion gas and air are after full pre-mixing apparatus 7 is mixed fully, export 76 in guide sleeve 54 enters burner inner ring 53 by mixed air, branch pore 57 through being arranged on the burner inner ring 53 arrives burner outer ring 52 again, by be installed in the top capping 14 and with burner 5 keep suitable igniting and sense flame distance igniter 2 and and after sense flame device 4 lights, form smooth combustion flame in the fire hole 56 on being arranged at burner outer ring 52.The main effect of burner inner ring 53 is to make the velocity field of air-flow even, all greater than flame propagation velocity, effectively prevents the generation of tempering phenomenon with the air velocity that guarantees each point under minimum thermic load.The majority amount minor diameter fire hole 56 that is provided with on the burner outer ring 52 makes burner have low thermal intensity of fire port, effectively prevents the generation from the flame phenomenon.Simultaneously because single fire hole diameter less than the critical aperture, effectively prevents the generation of tempering phenomenon.
Combustion gas and air after mixed fully enter in the burner 5, are lighted after-combustion by igniter 2, keep normal combustion after sense flame device 4 is sensed flame.Thermal-flame that fuel gas buring produces and flue gas are passed to the high-performance heat exchanger 8 of being with fin 82 by heat radiation and heat conduction with heat, pass to the current that therefrom flow through by it again, and water is heated up.Because gaseous mixture is to be pressed into burner 8 with certain pressure, the combustion chamber belongs to the malleation chamber, therefore the high-temperature flue gas that produces of burning can only be in the combustion chamber flows downward and enters bottom capping 12 along heat exchanger tube fin 82, enters smoke exhaust pipe by the smoke exhaust pipe interface 18 in the bottom capping 12 again and discharges.Because heat exchanger 8 adopts monometallic aluminum alloy strip finned tube to spiral into the cylindrical screw shape, greatly increase effective heat exchange area, therefore in more effective absorption obvious heat of smoke, also absorb part latent heat in the flue gas, thereby have higher heat exchange efficiency and have condensation effect.The condensed water that produces in the combustion heat-exchange process flows into bottom capping 12, and is discharged by condensation-water drain 17.
