Abstract

The utility model relates to a cooking range with air preheaters, which solves the problem that cool air is directly utilized to engage in combustion in the known cooking range, which easily results in insufficient combustion and fuel wasting. The technical scheme includes: a combustor is arranged in the cooking range body, a cooker ring is arranged on the cooking range body, a flue is arranged in the cooking rang body, smoke exhaust holes open to the flue are arranged in the cooker ring, an annular air preheater is arranged between the combustor and the flue and is communicated with the combustor, further, an annular air preheater is arranged at the outside of the flue and is connected with the air preheater between the combustor and the flue. The utility model can be applied to various cooking ranges for kitchen work.

Description

Cooking stove

Technical field

The utility model relates to a kind of cooking stove, particularly a kind of cooking stove that has air preheater.

Background technology

Cooking stove is the kitchen range that are used for cooking in people's daily life.Cooking stove includes body of heater, is provided with burner in body of heater, and body of heater is provided with the pot circle, when cooking stove uses, pot is placed on the pot circle, and fuel is in the burner internal combustion, and the heat of generation heats pot.In the present known cooking stove, air blast is directly connected on the burner, air is blown into burner to provide fuel combustion required oxygen; The hot flue gas that the burning back produces directly enters air.In known cooking stove, because directly entering burner, cold air participates in burning, cause combustion efficiency bad, fuel can not completing combustion; And the hot flue gas that the burning back produces directly enters air, and heat energy wherein is wasted.Known cooking stove existence wastes energy and the air-polluting problem.

In industrial boiler, much all equipped air preheater, mode by heat exchange is discharged thermal energy transfer in the flue gas to boiler in the air that enters boiler, to the heat recovery in the flue gas, and improved the air themperature that enters boiler, improve the working condition of boiler, make fuel combustion more complete, energy savings also reduces air pollution.The air preheater complex structure that uses on the Industrial Boiler, cost height, volume are big, are difficult to be suitable in Civil energy-saving cooking stove.

Summary of the invention

Participate in burning directly in order to solve existing cooking stove cold air, combustion efficiency is bad, cause to waste energy and the air-polluting problem, the utility model provides a kind of cooking stove that has air preheater, and the waste heat in the hot flue gas that this cooking stove utilization burning back produces adds hot-air; Waste heat in the flue gas is recycled, improved the temperature of the air that enters burner, improved combustion position; Energy savings has also reduced air pollution.

The technical scheme that its technical problem that solves the utility model adopts is:

Burner is arranged in body of heater, and body of heater is provided with the pot circle; Flue is set in body of heater, the exhaust smoke hole that leads to flue is set in the pot circle, the annular air preheater is set between burner and flue, air preheater is communicated with burner; An annular air preheater is set in the flue outside again, and is connected with air preheater between burner and the flue.Chimney is set is connected, blast pipe is set is connected with air preheater with flue.

When using this cooking stove, air enters air preheater from blast pipe, enter burner after in air preheater, being heated and participate in burning, the hot flue gas that burning produces enters flue through exhaust smoke hole, contact with the outer wall of air preheater, air in the heating air preheater is discharged through chimney then.Because it is higher to enter the air themperature of burner, better when combustion position directly enters than cold air, fuel combustion is more abundant, has avoided unburnt situation, has reduced air pollution.High temperature air also makes the less fuel of burner dissipated can reach the higher temperature that satisfies instructions for use, has reduced fuel consumption, energy savings.When the heat in the flue gas passed through air preheater, a part of heat had been reduced the temperature of discharging flue gas by the absorption of air in the air preheater, has reduced thermal pollution.

The beneficial effects of the utility model are:

Improved the air themperature that enters burner, improved combustion position, reduced the temperature of discharging flue gas, energy savings reduces and pollutes; Simple in structure, make easily, cost is low.

The specific embodiment

Fig. 1, Fig. 2, Fig. 3 are the schematic diagram of the utility model embodiment one.As shown in the figure: burner 3 is arranged in body of heater 1, and burner 3 is provided with fuel feed pipe 4 and air compartment 5; Be provided with flue 6 in the body of heater, chimney 8 links to each other with flue 6; Pot circle 2 is set on body of heater 1, in the pot circle, is provided with exhaust smoke hole 7, lead to the flue 6 in the body of heater; Between flue 6 and burner 3 air preheater 10 is arranged, air preheater 10 communicates with the air compartment 5 of burner 3, and air preheater 10 is provided with blast pipe 9.When using cooking stove, air enters air preheater 10 by blast pipe 9, is heated the laggard air compartment 5 of going into, and is blown into burner 3 then and participates in burning; The hot flue gas that burning produces enters flue 6 by exhaust smoke hole 7, to air flowing heating in the air preheater 10, discharges through chimney 8 then.Present embodiment has improved the air themperature that enters burner 3, has improved combustion position, has reduced the temperature of discharging flue gas, has energy savings, reduces the effect of polluting; Present embodiment is simple in structure, making is easy, cost is low.

Fig. 4, Fig. 5, Fig. 6 are the schematic diagram of the utility model embodiment two.As shown in the figure: burner 3 is arranged in body of heater 1, and burner 3 is provided with fuel feed pipe 4 and air compartment 5; Be provided with flue 6 in the body of heater, chimney 8 links to each other with flue 6; Pot circle 2 is set on body of heater 1, in the pot circle, is provided with exhaust smoke hole 7, lead to the flue 6 in the body of heater; Between flue 6 and burner 3 air preheater 10 is arranged, air preheater 10 communicates with the air compartment 5 of burner 3; In flue 6 outer setting air preheater 11 is arranged, air preheater 11 communicates with air preheater 10, and air preheater 11 is provided with blast pipe 9.When using cooking stove, air enters air preheater 11 by blast pipe 9, enters air preheater 10 after the first heating, heats the laggard air compartment 5 of going into once more, is blown into burner 3 then and participates in burning; The hot flue gas that burning produces enters flue 6 by exhaust smoke hole 7, to air flowing heating in air preheater 10 and the air preheater 11, discharges through chimney 8 then.Present embodiment has increased an air preheater 11 than embodiment one, and the air preheat better effects if has further improved energy savings and reduced the effect of polluting.
