The specific embodiment
As shown in Figure 1, 2, the utility model combustor comprise housing 2, be located at housing 2 one sides blower fan 1, be located at blower fan outer guard 12 and igniter 13, the burner of being located at the housing port of export, main admission line 14 and ever-burning flame admission line 11.Described burner is located at the little combustion barrel 17 of large-scale combustion tube bottom by large-scale combustion tube 16, and the combustion gas of being located at little combustion barrel bottom divides part 9, and the airduct 5 of being located at the combustion barrel periphery constitutes with the combustion chamber 4 of being located at little combustion barrel upper end.The external diameter of large-scale combustion tube 16 is little than the internal diameter of airduct 5, and its top is provided with quoit 21 and accepts mutually with airduct 5.The step place that airduct 5 is located at flange 3 is connected with housing 2.Large-scale combustion tube 16 and the combustion chamber 4 sidewalls plurality of rows inclination air gap 18,22 that evenly distributes, rectangular seam shape air gap 18,22 tilt in the same direction and equidistantly arrange.Combustion gas divides the bottom of part 9 to join with main admission line 14 and is communicated with, and the top of main admission line 14 is provided with external screw thread for one section, and it can divide part 9 to be spirally connected with tapped combustion gas.Combustion gas divides part 9 sidewalls to be provided with combustion gas venthole 20, and it generally is made as more than four, and the utility model is established six combustion gas ventholes 20.Little combustion barrel 17 sidewalls are evenly distributed with some air inlets hole 19, and an inverted combustion chamber 4 is established in the port of little combustion barrel 17, and this combustion chamber 4 is cylindric, and its sidewall is established plurality of rows air gap 22, and this air gap 22 is a premix gas venthole.Thereby a screw rod 8 passes the center screw-in combustion gas of combustion chamber 4 divides the top of part 9 that combustion chamber 4 is fixing.The bottom that large-scale combustion tube 16 is passed at ever-burning flame admission line 11 tops is close to igniting pin 10.First the entering in the little combustion barrel 17 from air admission hole 19 of air-flow that is driven by blower fan is pre-mixed with the combustion gas that enter from combustion gas venthole 20, premix gas enters in the large-scale combustion tube 16 along clockwise direction from the air gap 22 of combustion chamber sidewall, this premix gas mixes with the air that air gap 18 from large-scale combustion tube 16 sidewalls enters in the counterclockwise direction in large-scale combustion tube 16 more once more, so just form a circle cold airflow at the inner surface of large-scale combustion tube 16 and the outer surface of combustion chamber 4, effectively isolated combustion flame, prevented that combustion barrel and combustion chamber from being hardening cracked, being out of shape.Significantly reduce the possibility of tempering simultaneously, prolong the service life of burner.Combustion gas mixes through twice with air in addition, reaches abundant burning, and waste gas content is significantly less than national standard.
In addition, strong for flame is concentrated, establish a fire-collected ring 7 at the top of burner, flame is led.Because helical form flame can form a hollow shape low-temperature space in the centre,, make uniformity of temperature profile in the combustion chamber so a circle premix gas venthole 24 is set at the top of combustion chamber 4.Housing 2 vertically is provided with rubbish settling chamber 25 in the part bottom, and the rubbish that falls from burner accumulates in the rubbish settling chamber 25, away from blower fan, is beneficial to blower fan and runs well.
The course of work of the present utility model is as follows: connect power supply, blower fan is started working; Click button ignition switch, electronic ignition work is also delayed time a period of time; Open the ever-burning flame valve, combustion gas is lighted by electronic ignition from the top ejection of ever-burning flame admission line 11; Open main air valve, combustion gas mixes in the premixer from the air that combustion gas divides combustion gas venthole 20 ejection of part 9 sidewalls and air admission hole 19 from little combustion barrel 17 to enter, then from the shape ejection and lighted in the shape of a spiral of the air gap 22 of combustion chamber sidewall by ever-burning flame, from the air gap 18 of large-scale combustion tube 16 sidewalls be reverse acting spiral shape leaked-in air with from the air gap 22 of combustion chamber sidewall in the shape of a spiral the premix gas of shape ejection mix, it is fully burnt.
