Description

A kind of stove and accessory

Technical field

The utility model relates to the especially stove and accessory of synthol base class liquid fuel evaporation burning of a kind of liquid fuel.

Background technology

The stove and accessory that use in existing hotel and kitchen, hotel, only being fit to diesel oil is fuel, produces required big firepower by the blower fan vaporization combustion, its weak point is, the use cost height, and flue gas is big, the flue dust that splashes is many, contaminated environment and food, and inactive gap can not stay the little flare of restriking; This stove and accessory synthol base class liquid fuel that also is not suitable for burning; And the stove and accessory of existing burning synthol base class liquid fuel, because firepower is little, fuel consumption is big, discharge rate is difficult to shortcomings such as control, is not suitable for hotel and kitchen, hotel again and uses.

The utility model content

The purpose of this utility model will overcome above-mentioned deficiency exactly, provides a kind of and is particularly suitable for that synthol base class liquid fuel is used in hotel and kitchen, hotel, use cost is low, firepower is big, no flue dust splashes and peculiar smell, Environmental Safety, fuel saving, discharge rate are easy to control, can stay the stove and accessory of the flare of restriking in of short duration inactive gap.

For achieving the above object, the technical solution of the utility model is, this stove and accessory comprises furnace shell and the flue of establishing within it, leaves the wind chamber between this furnace shell and flue, and this wind chamber is communicated with the ajutage of air blast, described flue open topped, the lumen of described flue is the combustion chamber, has some ventilating openings that connect vented cavity and combustion chamber on described furnace wall, and the nozzle that is communicated with fuel conductor is located on the middle part, described flue bottom surface, outside this nozzle, be covered with nozzle casing, on this nozzle casing, have mouth.

As improvement of the present utility model, the fuel ejiction opening of described nozzle is opened the top at this nozzle, and the mouth on the described nozzle casing is opened on this nozzle casing upper portion side wall, and the height of described nozzle casing is the high 60-100% of described furnace wall.

As another kind of improvement the of the present utility model, the madial wall of described flue is a male and fomale(M﹠F), and the rhythm ventilating opening is oblique on the described furnace wall enters described combustion chamber from this convex surface respectively.

As another kind of improvement the of the present utility model, the interior diameter of described flue is 70-120mm.

As another kind of improvement the of the present utility model, the diameter summation of all ventilating openings is 100-120mm on the described furnace wall.

As another kind of improvement the of the present utility model, above described flue, be provided with the lid that heats of the logical burner of band.

The utility model stove and accessory is according to the characteristics of synthol base class carburretion burning, in order to reach the utility model purpose, nozzle is located on the middle part, flue bottom surface, and its fuel ejiction opening opened in its top, make the fuel of its ejection upwards rush at the high-temperature region on nozzle casing top, thereby carburretion is fast and abundant, helps burning, increases firepower; Nozzle casing of the present utility model is higher, makes its top be in the high-temperature region on top, combustion chamber, can significantly improve the temperature in the nozzle casing, makes the carburretion that sprays upward fast and abundant, helps burning and increases firepower; In addition, the utility model inboard wall of furnace is a male and fomale(M﹠F), can prevent from effectively that fuel vapor in the combustion chamber from directly being blown to spill; Its flue interior diameter is 70-120mm, make this stove and accessory both reach hotel, the needed big firepower in kitchen, hotel, has realized fuel savings again, has reduced the purpose of use cost; The summation of each the ventilating opening diameter on its furnace wall is 100-120mm, helps fully burning and increases firepower and can stay the flare of restriking in inactive gap; Uncovered top is provided with the lid that heats of the logical burner of band on its flue, and it is abundant to help in the combustion chamber fuel and air mixed combustion, can significantly improve firepower.

Because the result of above-mentioned comprehensive function, make the utility model stove and accessory be particularly suitable for hotel and kitchen, hotel use synthol base class fuel, has big, the fuel saving of firepower, use cost is low, no flue dust splashes and peculiar smell, Environmental Safety, discharge rate is easy to control, can stay remarkable advantages such as the flare of restriking in of short duration inactive gap.

Description of drawings

This accompanying drawing is the utility model cutaway view.

The specific embodiment

As shown in the figure, this stove and accessory comprises furnace shell [1] and installation flue [3] within it,

Leave wind chamber [2] between furnace shell [1] and the flue [3], wind chamber [2] is communicated with the ajutage [8] of air blast by furnace shell [1] bottom, flue [3] open topped, the lumen of flue [3] is combustion chamber [4], the madial wall of flue [3] is a male and fomale(M﹠F), on its convex surface, have some ventilating openings that connect vented cavity [2] and combustion chamber [4], the lower central that is combustion chamber [4] on middle part, flue [3] bottom surface is equipped with nozzle [6], this nozzle [6] is fixed in flue [3] bottom, and bottom flue [3], be communicated with fuel conductor [7], top at nozzle [6] has the fuel ejiction opening, outside nozzle [6], be covered with nozzle casing [5], on nozzle casing [5] top week sidewall, have some mouthfuls, above flue, be equipped with and heat lid [9] with some logical burners.

Of particular note, in order to determine the reasonable altitudes of the utility model nozzle casing [5], in on probation, be provided with it and highly be no more than more than 10%, 30%, 60%, 80%, 90% and 100% etc. high groups of flue [3] wall, the result is with between 60% to 100%, and its upper temp is higher, and vaporization of fuel is fast and fully in it, help to increase firepower, thereby the height of nozzle casing of the present utility model [5] is got the high 60-100% of flue [3] wall.

What specify is more again, in order to determine in the interior diameter size (being the size of combustion chamber) of the situation lower furnace [3] that guarantees enough big firepower and the relation of fuel saving, the utility model be provided with the flue interior diameter be respectively 30,50,70,80,90,100,110,120,130 and plurality of specifications such as 140mm try out, though the result is less than the fuel saving of 70mm, but firepower is not enough, and the fuel consumption more than the 120mm is excessive, and vaporization combustion is undesirable, thereby the utility model flue [3] interior diameter is selected 70-120mm for use.

What another point specified is, in order to determine that the utility model stove and accessory is guaranteeing that carburretion sufficient combustion and inactive gap can stay under the prerequisite of the flare of restriking, ventilating opening size and rational ventilation amount on its flue [3] wall, tried out on flue [3] wall each ventilating opening diameter summation respectively and be 60,70,80,90,100,110,120,130,140 and plurality of specifications such as 150mm, the result is that 100-120mm is better with each ventilating opening diameter summation, thereby each ventilating opening diameter summation adopts 100-120mm on the utility model flue [3] wall.

When using the utility model stove and accessory, this stove and accessory is placed supporting prefabricated kitchen range hall, start blower fan, open ajutage and fuel conductor switch, get final product the ignition combustion chamber, then regulate air quantity and fuel inlet by switch respectively, will produce the spiralling big flare that blazes, as need suspending big fire with fuel saving falling of short duration gap such as dish, and don't think all flame-out causing igniting trouble again, can close P cock and only stay the flare of restriking, convenient, suitable.
