Abstract

Disclosed is a device which uses tail gas waste heat of a cooking stove, including an exhaust pipe(4) which is installed on the rear part of a stove body(1) and is communicated with a smoke vent(3) which is located on the rear side of a stove body heating chamber(2). A heat exchanger(5) is arranged in the exhaust pipe(4), the heat exchanger(5) is composed of serpentine pipes which are installed with heat fins(6) and are provided with a water inlet(7) and a water outlet(8). The device can use the tail gas waste heat of the cooking stove to heat water and produce hot water, so energy can be saved effectively.

Description

Cooking stove using waste heat from tail gas use device

Technical field

The utility model relates to Civil energy-saving cooking stove, further is meant the using waste heat from tail gas use device of cooking stove.

Background technology

In the prior art, the cooking stove that the dining room of family, particularly hotel, restaurant, all kinds of enterprises and institutions all will be used cooking, be cooked.High-temperature tail gas after the fuel combustion of used cooking stove is drained by flue, and the also emptying thereupon of a large amount of heats that tail gas is entrained has wasted.

The utility model content

The technical problems to be solved in the utility model is, the defective at prior art exists designs a kind of cooking stove using waste heat from tail gas use device, and it can utilize the cooking stove using waste heat from tail gas to add hot water and produce hot water, with effective energy savings.

The technical solution of the utility model is, described cooking stove using waste heat from tail gas use device comprises the smoke exhaust pipe that is installed in the stove rear portion and is communicated with the exhaust opening of stove heating clamber rear side, its design feature is, in described smoke exhaust pipe heat exchanger is housed, this heat exchanger is formed by heat transmission fin being housed and being provided with into the coiled pipe of water interface and water outlet interface.

Below the utility model made further specify.

Referring to Fig. 1 and Fig. 2, cooking stove using waste heat from tail gas use device of the present utility model comprises the smoke exhaust pipe 4 that is installed in stove 1 rear portion and is communicated with the exhaust opening 3 of stove heating clamber 2 rear sides, and its design feature is in described smoke exhaust pipe 4 heat exchanger 5 to be housed; As shown in Figure 3, this heat exchanger 5 is formed by heat transmission fin 6 being housed and being provided with into the coiled pipe 9 of water interface 7 and water outlet interface 8.

Burner in the combustion chamber 11 of described stove heating clamber 2 bottoms can be gas burner or oil burner, also can be coal fired combustion or other fuel burner.

Described heat exchanger 5 adopts finned heat exchanger shown in Figure 3, also can adopt the heat exchanger of other suitable structure in the prior art.

Test shows, the exhaust temperature of conventional cooking stove is up to 400 ℃-450 ℃ or higher, after in smoke exhaust pipe 4, finned heat exchanger 5 being installed, the heat exchange efficiency of this heat exchanger is high and can not influence the normal discharging of flue gas, can fully absorb the heat in the tail gas, make the water in the coiled pipe obtain heating, continuously output hot water.Drop to below 100 ℃ through the flue-gas temperature after the heat exchanger heat exchange.

As known from the above, the utility model is a kind of cooking stove using waste heat from tail gas use device, and it can utilize the cooking stove using waste heat from tail gas to add hot water and produce hot water, has effectively saved the energy.
