Embodiment Construction
[0020] Such as figure 1 As shown, this burner based on flue gas preheating air includes a smoke exhaust pipe 2 arranged under the furnace 1. The smoke exhaust pipe 2 can be made of materials that are easy to exchange heat or heat insulating materials. The smoke exhaust pipe 2 is equipped with There is a heat exchange tube 4 with an air channel 3 inside and made of heat-conducting material. The upper end of the heat exchange tube 4 is closed and the lower end is connected with an air intake mechanism 5 that allows outside air to enter the air channel 3. The wind mechanism 5 is provided with an air distributor, through which the air can be evenly distributed in the air channel 3 to obtain sufficient heat exchange. A combustion chamber 6 is provided below the furnace 1 and the combustion chamber 6 communicates with the fuel pipe 7 , the combustion chamber 6 communicates with the upper end of the air passage 3, so that the air in the air passage 3 can enter the combustion chamber ...

The invention belongs to the technical field of kitchen ranges, and particularly relates to a burner preheating air through smoke and an application method thereof. A heat exchange pipe which is internally provided with an air channel and made from a heat conductive material is arranged in a smoke exhaust pipe, the upper end of the heat exchange pipe is closed, and the lower end of the heat exchange pipe is connected with an air inlet mechanism capable of enabling outside air to enter the air channel. A burning chamber is arranged under a hearth and communicates with a fuel pipe. The burning chamber communicates with the upper end of the air channel. A burning chamber outlet communicating with the hearth is formed in the upper end of the burning chamber. An annular smoke channel is formed between the smoke exhaust pipe and the heat exchange pipe, and the upper end of the smoke channel communicates with the hearth. The smoke channel is located on the periphery of the air channel, and heat exchange between the smoke channel and the air channel can be achieved through the heat exchange pipe. The lower end of the smoke channel is connected with a smoke exhaust mechanism capable of discharging smoke out of the smoke exhaust pipe. Compared with the prior art, the burner has the advantages that the design is reasonable, the burning efficiency is high, the heat utilization rate is increased, and the influence on the environment can be reduced.
Description
technical field [0001] The invention belongs to the technical field of stoves, and in particular relates to a burner for preheating air based on flue gas and a use method thereof. Background technique [0002] At present, most cookers on the market install the burner on the cooker body. The compatibility between the burner and the cooker body in terms of combustion and heat exchange is relatively low. Because the combustion air is not preheated or the preheating is unreasonable, the combustion efficiency of the burner is relatively low. [0003] For example, the Chinese patent literature discloses a stove burner [Application No.: 201510237022.4]. The casing is a sealed hollow structure. The groove is equipped with a horizontal air guide plate, which separates the groove into a lower premixing chamber and an upper combustion chamber. The air guide plate is provided with air outlets that penetrate up and down, and the housing is respectively equipped with The air inlet pipe ...
