CN2318531Y - Liquid gas stove and gas stove with bladder - Google Patents

Abstract

The utility model relates to a liquid gas stove and a gas stove with a bladder, and is characterized in that a plurality of simplified device structures are additionally arranged before and after an original gas stove with the functions of insulating heat and guiding the heat exchange in gas. The utility model can effectively improve the heat efficiency of the gas stove, has fierce flame and shortened cooking time, and can reduce the pollution to the environment, through a slight change of the structure of the existing gas stove.

Description

The liquefied gas furnace and the gas burner of band courage

The utility model relates to the domestic cookers technical field.

Structurally there are two shortcomings in present household liquified steam stove and gas burner, and the one, flame is to multi-faceted radiation; The 2nd, combustion air is a normal temperature.So the present liquefaction stove and the radiation loss of gas burner are big, the combustion mechanism of fuel gas is poor, and particularly under the impure situation of the makings of liquefied gas, incomplete combustion is separated out a large amount of carbon, causes the bottom of a pan black, and pot is placed on the there, just the there is done and has polluted.Therefore, a large amount of at present liquefied gas furnace and gas burners that use are a kind of energy consumption height, and efficient is low, can produce the cooker of pollution sometimes again.

The purpose of this utility model is that a kind of flame that makes of design can only be towards the bottom of a pan direction, simultaneously again can preheated air, reach energy-saving and cost-reducing effect thereby improve combustion mechanism.Simultaneously simple again existing liquefied gas furnace and gas burner done some structural change.

Realization of the present utility model is the spray of existing liquefied gas furnace and gas burner combustion mouth cover, as individual reverse electric light cover; Make a big heat-insulating room at the bottom periphery of spray combustion mouth in addition; Place the heat insulation loop of an internal diameter greater than the some sizes of external diameter of cover in the top bit of cover, in addition, all spray combustion mouth holes are straight up.

Below in conjunction with accompanying drawing given the utility model embodiment is further described, as shown in the figure, the mixing tube 2 that fuel gas is entered a convergent-divergent shape by conduit 1 when liquefied gas furnace and gas burner are lighted, flow velocity caused variation when fuel gas was managed by convergent-divergent shape, produce siphonage, hot-air is all around entrainmented in the convergent-divergent pipe fully mix with fuel gas.Mixed gas is in hole 4 completing combustions of spray combustion mouth.Covering the heat that the cover 5 of spray combustion mouth 3 absorbed this moment is absorbed by hot-air mobile between heat-insulating room 6 and cover 5 again.When flue gas will leave pot 8 outer surfaces, meet, form countercurrent heat exchange with the cold air that enters heat insulation loop 7.

Be used for covering being and throwing the face hollow body of spray combustion mouth, this body plays burnt light action, among full Jiao of all flame on the bottom of a pan, prevent that flame from reducing the astigmatism loss towards unnecessary direction radiation, improve the temperature of combustion zone simultaneously, help burning of mist, reduce loss of the inadequacy burning for chemistry mechanics reason, also have the heat storing and heat preserving effect.Because cold air, hot-air, carbon dioxide etc. exist the severe difference to utilize these severe difference and siphonage between them, make gas produce very complete available natural gas circulation, cold air severe maximum at first, it constantly moves downward from the gap on heat insulation loop and heated pot limit, the carbon dioxide flue gas gentlier moves upward, form the heat exchange of adverse current, cold air be heated (heat absorption) for the first time and the hot flue gas that will leave the bottom of a pan lowered the temperature (being heat release) reduced exhaust gas temperature like this, reduce flue gas loss.When first heated air flows through from the gap of the outer surface of parabolic hollow body and heat-insulating room inboard, owing to be the strong combustion zone of burning in the parabolic body, its hull-skin temperature height, first so heated air is once heated again.Twice heated hot air heated enters in the convergent-divergent pipe under the effect of siphonage fully mixes with fuel gas, and the activation energy of fuel gas is increased severely, and has improved the mechanism of fuel combustion.(dividing so that the mobile division of overdraught is just general) spray combustion mouth hole is to avoid the flame forward to wash away cover straight up, but directly to the bottom of a pan.

The liquefied gas furnace and the gas burner that facts have proved the utility model band courage have the reduction exhaust gas temperature, stop distributing of flame, improve the activation energy of fuel.Therefore compare with the gas furnace that generally uses now and have thermal efficiency height, energy-saving and cost-reducing advantage can also overcome the carbon of analysing that causes because of fuel is impure simultaneously, reduces emission amount of carbon dioxide protection environment, and faster and better the eating of the ripe meal of the not only violent but also prosperous cooking of flame.

Claims (1)

1. The liquefied gas furnace and the gas burner of band courage is characterized in that the spray of gas furnace is fired mouth hole (4) straight up; On spray combustion mouth, covering a parabolic hollow body (5); Fence up with heat-insulating room (6) around the portion of spray combustion gonys; Near the top of cover, place the heat insulation loop (7) of an internal diameter greater than the some sizes of cover (5) external diameter.
