Now in conjunction with the accompanying drawings the structure of lighter hydrocarbons normal pressure burner is described in detail:

By Fig. 1,2,4,5, liquid level gauge (35) is equipped with in fuel tank (26) left side, and fuel tank cap (36) is arranged at the top, and its inboard is equipped with and is hung sheet (37).The fuel tank lower right side is equipped with output valve (27), this valve (27) right-hand member is connected with petroleum pipeline (29), and fastening with the locking card of spring (28), petroleum pipeline (29) right-hand member is connected with input adapter (4) with oil inlet pipe (6), also uses the locking card of spring (28) fastening; (see figure 4) oil inlet pipe (6) right-hand member is connected with control valve joint (5), is connected in control valve valve body (2) again, and valve body (2) one ends are connected with burner by valve pipe (3), and valve body (2) other end is equipped with handwheel (1) or knob.

By Fig. 1,4,5, valve pipe (3) links to each other with nozzle (21), and needle (22) and spring (23) are housed in the valve pipe (3); Nozzle (21) is connected with the joint (20) of base (9), fire ring (31) closely cooperates and is loaded in the annular groove of base (9), copper mesh cloth combustion chamber (19) closely cooperates and is loaded in the annular groove of fire ring (31), the gap is left in the annular groove of base (9) and fire ring (31) bottom, constitute an oil guide groove (25), fire ring (31) bottom is uniform by 360 °, there is oil seepage hole (24) to communicate with copper mesh cloth combustion chamber (19), interior air-breathing cover (16) places fire ring (31) inboard, and outer air-breathing cover (17) places fire ring (31) outside.

By Fig. 1, burning bucket kuppe (12) is by concentric locating pin (8) and (18) and spring card (11) and (13) (Fig. 1,5) and interior air-breathing cover (16), outer air-breathing cover (17) formation one, and form interior induction chamber (33), outer induction chamber (34) and combustion chamber (30), Choked flow cover (15) and reflector (14) are equipped with in interior induction chamber (33) top, and the expanded metals radiation shield (7) that arc protrudes out is equipped with in burning bucket kuppe (12) top.

By Fig. 3, below, burner right side has a fire hole (32), and the fixing hole (10) by base (9) both sides can be installed on the different supporting systems, forms different burners.

The operation principle of this burner is as follows: (Fig. 1--the burner of a single head kitchen range of 5 expressions.) liquid fuel in the fuel tank (26) is under the effect of potential difference gravity, successively by output valve (27), petroleum pipeline (29), input adapter (4), oil inlet pipe (6), control valve joint (5) enters controlling valve (2), handwheel (1) to anticlockwise controlling valve (2), needle (22) just withdraws from backward, fuel just enters oil guide groove (25) by the aperture in nozzle (21) the place ahead, enter fire ring (31) infiltration copper mesh cloth combustion chamber (19) through the uniform oil seepage hole (24) in fire ring (31) bottom then, light copper mesh cloth combustion chamber (19) with pulse igniter or match by fire hole (32), flame is (30) internal combustion in the combustion chamber just.At this moment, just uniform aperture on interior air-breathing cover (16), outer air-breathing cover (17) circumference enters combustion chamber (30) participation burning to airborne oxygen by interior induction chamber (33) and outer induction chamber (34), make flame become blue and rise and pass the aperture of expanded metals radiation shield (7), make expanded metals radiation shield (7) become red and white, improve ignition temperature, enlarge burning area.The air-flow of interior induction chamber (33) can only quicken laterally to enter combustion chamber (30) under the effect that Choked flow cover (15) are arranged, and makes air-fuel ratio reach optimum state; Reflector (14) then carries out the choked flow reflection to the flame that comes in the scattering, and flame just evenly heats expanded metals radiation shield (7), makes expanded metals radiation shield (7) bring into play the infra-red radiation effect again.Liquid fuel in the oil guide groove (25) is in burner operation after 2 minutes, becomes gaseous state by the heat heating of fire ring (31) conduction and burns away, and improved the thermal efficiency, makes sufficient combustion.

Compared with prior art, light hydrocarbon atmospheric burner has following advantages: 1. need not be equipped with the pressurization of electric pump or air pump, light-hydrocarbon fuel is fully burnt, Make the designs simplification of burner. 2. use upper safe and reliable. 3. because constant pressure makes combustion process very stable. 4. range of application is very extensive. The resident who is applicable to rural area, farm, forest zone or island be used for cooking or Heating makes the resident no longer remove to use plant timber or raw coal, reduces the pollution in the atmosphere. 5. fuel tank places the appropriate location, utilizes potential difference can make lighter hydrocarbons flow into fully burning in the burner.
