Abstract

The utility model discloses a methane burner used to solve the problems of incomplete combustion and low heat efficiency existing in the present methane stove. The utility model comprises an air duct connected with a methane tank, and a stove connected with the air duct, wherein the stove comprises a stove face, a gas compartment, a mixture gas vent pipe, an air spout assembly, an adjustment sheet and a valve switch. The air duct has the diameter of 15 to 25mm, the stove hole of the stove face has the diameter of 0.4 to 0.8mm, and the hole distance is 3 to 4mm. The stove face has the diameter of 12 to 14cm, the gas compartment has the height of 6 to 8cm, and an air spout has the hole diameter of 4 to 6mm. The utility model can make full use of methane with low firedamp content during the start period of the methane tank and make the methane with normal firedamp content burned more adequately and more fiercely. Simultaneously, the utility model can also save a large amount of high-grade methane, greatly enhance the service efficiency of the methane and save the gas consumption of normal methane by more than 40%. The utility model greatly reduces the time of putting the methane tank into normal operation, obtaining the effects of low pressure, sparse burning and gas saving.

Description

Biogas burner

Technical field:

The utility model relates to a kind of biogas burner.

Background technology:

At present, in the good arm's length standard biogas of fermentation starting, its composition is 40% carbon dioxide and 60% methane, and its combustion heat value is lower, is generally 5000-5700 kilocalorie/cubic meter; In the initial start stage (being generally about 25 days to 30 days) of methane-generating pit, carbon dioxide content is very high in its gas of arranging, and about 50-70%, and the content of methane only has 30-40%, and visible institute calorific value is just lower.Existing biogas stove and accessory can't be lighted, can't use, and main cause is that methane content is too low, like this, always has a large amount of gases only to waste in the period at this section, goes back contaminated air.

In addition in general biogas stove and accessory uses, air pressure need reach 0.2 kg/cm (0.002MPa) when above, and biogas could smooth combustion in stove and accessory, otherwise can not normally use.Existing gas furnace generally is middle and high die mould, so when the pressure of methane-generating pit does not reach the minimum pressure of existing gas furnace, be wasted with regard to the combustible gas that a large amount of pressure are lower, methane content is lower is arranged.

Moreover, existing biogas stove and accessory is just on the basis of original gas stove, the aperture of nozzle is enlarged (being expanded by original φ 0.3-0.4 millimeter is the 0.06-1.0 millimeter), it also is not suitable for the characteristics of biogas, cause incomplete combustion, the thermal efficiency is lower, has wasted a lot of biogas, has reduced the utilization ratio of biogas.

Summary of the invention

The purpose of this utility model provides a kind of biogas burner, to solve the incomplete combustion that existing biogas stove and accessory exists, the problem that the thermal efficiency is lower.

The utility model comprises the wireway that links to each other with methane-generating pit, the stove and accessory that links to each other with wireway, and stove and accessory comprises boiler face, gas compartment, mist breather pipe, injector assembly, adjustment sheet, valve switch; The diameter of described wireway is the 15-25 millimeter; The firehole diameter of boiler face is the 0.4-0.8 mm dia, and pitch-row is that the 3-4 millimeter is uniform; The diameter of boiler face is 12-14 centimetre, and the height of gas compartment is 6-8 centimetre; Nozzle bore is the 4-6 millimeter.

The utility model can not only make full use of the methane-generating pit biogas that methane content is low in the starting period, and can also make that the burning of the normal biogas of methane content is more abundant, firepower is more violent, simultaneously can also save a large amount of high-quality marsh gas, the service efficiency of biogas is improved greatly, make the gas consumption of normal biogas save more than 40%.The utility model has been accelerated the normal time of using of methane-generating pit input greatly, about one month starting period by original, shorten to 3-4 days, and improved the performance of traditional biogas greatly, reach low pressure, lean-burn, province's gas.

The utility model is described in further detail below in conjunction with accompanying drawing.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the vertical view of Fig. 1.

The specific embodiment

The utility model comprises the wireway 7 that links to each other with methane-generating pit, the stove and accessory that links to each other with wireway 7, and stove and accessory comprises boiler face 1, gas compartment 2, mist breather pipe 3, injector assembly 4, adjustment sheet 5, valve switch 6; The diameter of wireway 7 is the 15-25 millimeter; The firehole diameter of boiler face 1 is 0.4-0.8 mm dia (boiler face is made with refractory), and pitch-row is that the 3-4 millimeter is uniform; The diameter of boiler face 1 is 12-14 centimetre, and the height of gas compartment 2 is 6-8 centimetre; Gas compartment 2 is twice than common stove and accessory.Nozzle bore is the 4-6 millimeter.

The diameter of preferred wireway 7 is the 15-20 millimeter; The aperture of boiler face 1 is the 0.4-0.6 millimeter.

Boiler face 1 usefulness refractory is made.Injector assembly is the copper nozzle of belt switch.

Enforcement of the present utility model is very simple, can be only with the enlarged-diameter of the original wireway of from methane-generating pit, exporting, such as being originally that diameter is the 10-12 millimeter, now its wireway that changes the 15-25 diameter into is got final product (what simple eye burner can be with 15 mm dias, the eyes burner can adopt the wireway of 20～25 mm dias).

Claims

1, a kind of biogas burner comprises the wireway that links to each other with methane-generating pit, the stove and accessory that links to each other with wireway, and stove and accessory comprises boiler face, gas compartment, mist breather pipe, injector assembly, adjustment sheet, valve switch; It is characterized in that: the diameter of described wireway (7) is the 15-25 millimeter; The firehole diameter of boiler face (1) is the 0.4-0.8 mm dia, and pitch-row is that the 3-4 millimeter is uniform; The diameter of boiler face (1) is 12-14 centimetre, and the height of gas compartment (2) is 6-8 centimetre; Nozzle bore is the 4-6 millimeter.
