Abstract

The utility model relates to a stove burning liquid fuel or gas fuel, comprising a housing, a liquid fuel tank, a pressurization system, a burner, and a main gate valve. The stove burning liquid fuel or gas fuel is suitable for cities and countryside. The stove burning liquid fuel or gas fuel adopts the swirl burner which is designed according to the Venturi principle and uses combustible gas fuels or liquid fuels, and the structure is novel. The thermal efficiency is largely increased.

Description

Stove burning liquid fuel or gas fuel

The utility model relates to a kind of home-use stove and accessory.

The stove and accessory kind of making fuel with liquefied petroleum gas is a lot, but owing to be subjected to the restriction of fuels sources, is difficult for promoting, and general family popularizes difficulty.The stove and accessory of single combustion of liquid fuel also has multiple, novel liquid fuel stove and accessory (CN2037038U) is exactly wherein a kind of, molten fuel tank of this stove and accessory and stove and accessory are one, the structure of tangential admission vortex strip wind is adopted in the combustion chamber, the transfer the fuel voltage-stabilizing system, adapted dedicated liquid fuel, but this stove and accessory only limits to combustion of liquid fuel, inapplicable again to gaseous fuel.

The purpose of this utility model just provides a kind of stove and accessory that uses the novel burner of liquid fuel, gaseous fuel and use this burner.

Design of the present utility model is: burner adopts vortex, according to the venturi law, uses for reference the principle of aero-engine and designs.Burner is connected with appendix, woven hose, air jet pipe, comes the quantity combusted of fuel metering by the control of gate valve.Liquid, gaseous fuel pass through burner combustion.

Elaborate below in conjunction with accompanying drawing:

Fig. 1 is a schematic top plan view of the present utility model;

The utility model integral layout is by the symmetrical structure that Figure 1 shows that two burners.Liquid fuel tank 1 is being supported by woven hose 16 and is vertically exceeding boiler face.Respectively there are two branch roads on woven hose 16 both sides in stove and accessory housing 3, and a branch road links to each other with annular economizer bank 9, annular economizer bank 9 one termination sparge pipes 22, and another branch road links to each other with a liquid valve 13.The appendix 4 that housing 3 edges are equipped with three-way pipe 15 and are attached thereto.The support 27 that supports preheating dish 11 is housed on the stove and accessory housing 3, and preheating dish 11 is screwed on support 27.Preheating dish 11 is an annular, is used to adorn the liquid fuel that preheating is used.Burner 8 is placed on the preheating dish 11.

The utility model has compression system, comprises the storage pressure cylinder 24 of electric booster 18, stove and accessory central authorities, two gas receivers 2, Boost bicycle pump 14, the air gauge 19 of symmetry.Storage pressure cylinder 24, gas receiver 2 usefulness tubules are connected both available electric booster 18 electronic superchargings, also available Boost bicycle pump 14 hand superchargings.Compression system is connected with total gate valve 5 by air jet pipe 21.

Fig. 2 is the partial structurtes schematic diagram of stove and accessory;

Fig. 3 is the axial section schematic diagram of burner;

Fig. 4 is the schematic top plan view of burner;

Fig. 5 is the burning cover structural representation;

The main inventive point of the utility model is cylinder burner 8 according to the venturi law, uses for reference the aero-engine principle, in cylinder inside, with metallic plate be separated with one up and down wide, middle narrow axial cross section be butterfly shape eddy combustion chamber 23, as shown in Figure 3.Burner 8 inner radial have the swan-neck 10 of a band burner port 29, and swan-neck 10 is communicated with combustion chamber 23, and the mouth of pipe is 23 the narrowest positions over against the combustion chamber.Burner 8 sides are provided with nozzle 25 by following appropriate location, and nozzle 25 connects combustion chamber 23.From the fuel of nozzle 25 spirts in the combustion chamber 23 the narrowest receipts wounds.Total gate valve 5 is suspended in the nozzle 25, and appendix 4, air jet pipe 21, sparge pipe 22 insert total gate valve 5, is subjected to gate valve control with fuel metering and air inflow.There are many burner ports 28 that communicate with combustion chamber 23 burner 8 upper ends.Circular venting plate 12 is placed on the burner 8, the burning cover of using when being placed with four side band mesh for combustion of liquid fuel on the venting plate 7.During burning gases fuel, do not need burning cover 7.

As shown in Figure 2, the annular section of annular economizer bank 9 is arranged on burner 8 bent intermediate pipes 10 tops.Annular economizer bank 9 one termination woven hoses 16, the other end links to each other with sparge pipe 22.Point liquid valve 13 is installed in preheating dish 11 tops, makes the liquid fuel in the woven hose 16 flow into preheating dish 11 just through a liquid valve 13.

The course of work of the present utility model:

Burning gases fuel: fuel enters stove and accessory through appendix 4 from three-way pipe 15, is subjected to total gate valve 5 controls.Open total gate valve 5, fuel enters combustion chamber 23 from nozzle 25, lights with electronic lighter 6.Fuel is in burner port 28 and burner port 29 burnings.

Combustion of liquid fuel: at first the plug 26 of electric booster 18 is connect power supply or gives gas receiver 2,24 inflations of storage pressure cylinder with Boost bicycle pump 14, be charged to 2.5 atmospheric pressure, observe from air gauge 19, inflation once can be used one day.Open liquid case switch 20, fuel is divided into two branch roads along woven hose 16, and a branch road flows to a liquid valve 13, and another branch road is flowed through annular economizer bank 9, sparge pipe 22 to total gate valve 5.Open a liquid valve 13, make small amount of fuel flow into preheating dish 11, close close point liquid valve 13 immediately.With the ignited fuel in the preheating dish 11, open total gate valve 5 with electronic lighter 6, connect the pressed gas in the air jet pipe 21 of compression system and enter nozzle 25 simultaneously through the fuel that annular economizer bank 9 preheatings flow into sparge pipe 22.Under the effect of pressed gas, through the liquid fuel of preheating, in combustion chamber 23, carry out the high speed vortex and receive wound, atomizing at the narrowest position, then from burner port 28, burner port 29 ejections, burning immediately.The flame of burner port 29 mainly is preheating annular economizer bank 9.

The utility model has the advantages that: burner is to be designed to vortex according to the venturi law, both can burn liquid fuel, and the burning gas fluid fuel improves the thermal efficiency significantly again, and city, rural area are all applicable.

Embodiment:

Liquid fuel tank 1 capacity is 15 liters, and 6 millimeters copper pipes of annular economizer bank 9 usefulness diameters curve.Burner 8 is high 55 millimeters, 80 millimeters of external diameters, and 23 the narrowest positions, combustion chamber, 27 millimeters apart from burner 8 upper ends, combustion chamber 23 width at narrow place is 2 millimeters.The inwall gradient that burner 8 contacts with swan-neck 10 is 8.5 degree.
