Vaporization combustion furnace for alcohol group fuel tool workflow of the present utility model is:
One, first, close state before using front each valve all should be in, heating rod 503 and ignition electrode 10 are all in off-position.
Two, appropriateness opens superpressure backflow inlet valve 101, allow liquid fuel through filter chamber cavity 102, inject in vaporizer 202 through feeder sleeve 103 again, the handle 406 be now connected with valve rod 404 in appropriate firepower control unit 4 of outwarding winding, after allowing flow in fuel expire vaporizer 202, firepower control unit 4 is flowed through again through vaporization chamber arm 204, fill priming chamber 502 successively again, nozzle chamber 605, cover point igniter cap 608 again until allow liquid fuel flow full bocca 604 through flame groove 603 and overflow, the fluid fuel now overflowed can be subject to Action of Gravity Field and wander in preheating box 701 through air distribution outlet 8, in time flowing into the about 10-15ml of the liquid fuel in preheating box 701, the handle 406 of firepower control unit 4 is closed.
Three, heating rod 503 switch is opened, heating rod 503 power supply protects control circui by time delay temperature, carry out time delay heating, then pin ignition switch and allow ignition electrode 10 discharge igniting, at this moment the liquid fuel in bocca 604 and on point igniter cap 608 is lighted, and the fuel expanded by heating lighted to flow in preheating box 701 and the fuel ignited in preheating box 701.Preheated web 703 flame cavity 602, from air distribution outlet 8 to combustion chamber 9 combustion, heats by flame in preheating box 701 like this, and preheated web 703 can transfer heat to the fuel in preheating box 701 after being heated, by the fuel accelerated combustion Fast exothermic heated.Again because flame cavity 602 lower surface has multiple absorber plate 606 fast endothermic to rise soon by the temperature of flame cavity 602, at this moment the fuel in nozzle chamber 605 and priming chamber 502 heats up and vaporizes, gradually bocca 604 has gaseous fuel ejection, the gaseous fuel of ejection is scattered at flame groove 603 mouthfuls of places, fully mix together with the air stream from air distribution outlet 8 during scattering, reach the object of burning completely.Just flame is had in combustion chamber 9 during self-ignition, so vaporization chamber inner sleeve 203 is constantly in heat absorption, the liquid fuel temperature rise volume in vaporizer 202 is made to expand and vaporize, at this moment increase by carburretion volume and affect, the pressure of vaporizer 202 can be higher, and the liquid in vaporizer 202 can flow into hopper from feeder sleeve 103 and superpressure backflow inlet valve 101 by higher pressure.
Four, when bocca 604 has gaseous fuel to spray combustion, the handle 406 of firepower control unit 4 can be rotated, first have liquid fuel to flow through when just opening, it is heat vaporized that liquid fuel meeting gravitate falls into priming chamber 502, and the gaseous fuel after vaporization can supply nozzle chamber 605 through appendix 405.Just have after liquid fuel flows through and flow through from vaporizer 202 gaseous fuel, gaseous fuel can pass through appendix 405, directly supplies nozzle chamber 605 spray combustion.This process room is complete, namely starts end.
In addition: a mode for preheating flame cavity 602 during power failure, can be taked also can to start.
When having electricity, can also only start separately with startup chamber.
Five: after stove and accessory starts, the handle 406 of adjustment firepower control unit 4, controls the flow of gaseous fuel, reach control the intensity of a fire must object.
Now, vaporizer 202 also produces the gaseous fuel needed for the various intensity of a fire along with the size of the intensity of a fire, forms a complete vaporization combustion flow process.
Six, backflow phenomenon is had because of stove and accessory normal combustion with in starting, can the solid impurity chip of can not vaporizing that vaporizer 202 wall comes off be entered in filter chamber cavity 102 through feeder sleeve 103 during backflow, chip is after reflux and filter net 105 leaches, be deposited in sewage draining exit valve 104 place suitable for reading, regularly can open sewage draining exit valve 104 and discharge.
