Abstract

The utility model relates to a medium-pressure liquefied petroleum gas furnace with a flue, which is composed of a furnace body, an ejecting tube, a combustor, cooker ring and a control valve. The inner wall of the furnace body is provided with an annular flue connected with a chimney. Water vapor, carbon dioxide, carbon monoxide and smoke gas generated when the furnace works can be exhausted through the flue and the chimney in time, the condition of combustion is improved, environmental pollution is reduced, operation is safe and convenient, and cost is low. A blower is not needed for assisting combustion, and energy is saved. The utility model is suitable for restaurants, hotels, restaurants and the dining rooms of enterprises and institutions to replace oil-burning stoves.

Description

Press petroleum gas stove in the band flue

The utility model relates to a kind of stove and accessory, and especially a kind of is the medium pressure furnace tool of fuel with gas.

It is 94224286.6 middle pressure petroleum gas stove that Patent Office of the People's Republic of China once disclosed a kind of patent No..Generally below 20KW, its duty is open to this stove thermic load, and flue gas freely is thrown into working space, and ratio of combustion is more abundant, can guarantee that carbon monoxide content is lower in the flue gas; If improve its thermic load, because burner dimensions restriction and gas pressure increase, burning is abundant not as the stove and accessory of low heat loads, and carbon monoxide content can not only influence health than higher in the flue gas, contaminated environment, and also security also reduces.Some stove and accessory such as the oil burner of identical thermic load, adopts the air blast auxiliary combustion, although improved combustion position, and big, the many power consumption of noise, contaminated environment, the cost of stove and accessory is also than higher.

The purpose of this utility model provides and a kind ofly can in time give off flue gas, improves the high heat load gas furnace of combustion position, and this Range structure is simple, with low cost, safe and reliable.

For achieving the above object, the utility model proposes following scheme: this stove and accessory includes stove and accessory body, induction tunnel, burner, pot circle and control valve, and the annular flue that is connected with chimney is arranged on the inwall of stove and accessory body.

Gas furnace of the present utility model owing to designed exit flue, has been strengthened air inducing speed, can in time flue gas be arranged to outdoor, and improve burning condition, reduce the generation of carbon monoxide, safe and reliable, simple structure makes that the stove and accessory cost is low, is easy to accept into people.

Be described further below in conjunction with accompanying drawing and embodiment.

Fig. 1 is the utility model front view;

Fig. 2 is the utility model vertical view;

Fig. 3 is the utility model left view;

Fig. 4 is the utility model right view.

Referring to whole accompanying drawings, Fig. 1,2 particularly, gas furnace of the present utility model, form by stove and accessory body, induction tunnel (6), burner (4), pot circle (2) and control valve (7), wherein the stove and accessory body comprises furnace body outer wall (5), inwall (3) and base (8), and an annular flue that is connected with chimney (1) is arranged on the inwall (3) of stove and accessory body.This flue is positioned at the top of inboard wall of furnace body, can not blow back in the furnace chamber after making cigarette enter flue, and the utility model has adopted the flue of the approximate C shape in cross section, and the inlet of cigarette is smaller and the flue chamber is bigger.Concrete way is that inboard wall of furnace body (3) is lower than outer wall (5), the upper surface of inwall inwardly top tilts, the outer wall of body of heater is slightly outwardly-bent, support a pot circle, the bottom surface of the upper surface that the outer wall of body of heater (5), inwall (3) tilt and pot circle (2) upward bent band circular arc has surrounded flue jointly.Owing to pot circle (2) can separate with body of heater, when frying pan is big, can take down a pot circle, frying pan contacts with the whole circle in the upper edge of body of heater, and this moment, said flue was made of jointly furnace body outer wall (5), the upper surface of inwall (3) inclination and the part of frying pan bottom surface.

In the above-mentioned gas furnace, the inwall of body of heater can be made with exotic material such as refractory brick, not only can be used as the component part of flue, but also can lower the influence of heat radiation to the user.In order to reduce the possibility that joint face leaks, burner (4) is made an integral body with induction tunnel (6) by casting; Inlet suction port in the control valve (7), outgassing nozzle were that bulk-breaking connects originally, now changed valve body embryo spare hot-die forging into, used more safe and reliable.Compression ignite steam stove tool in original in addition, body of heater pin height is generally about 30mm, and in the present embodiment, body of heater leg (9) is increased to minimum to more than the 100mm, and the bottom has sufficient air to supply with when making burning.
