Flue gas waste heat recovery cooker

Abstract

The invention relates to a flue gas waste heat recovery cooker which comprises a combustion chamber arranged in a cooking bench and a combustor located in the combustion chamber. The flue gas waste heat recovery cooker further comprises a heat exchange device for heat exchange between high-temperature flue gas exhausted from the combustion chamber and air. The heat exchange device is provided with a flue gas inlet and an air outlet. The upper portion of the combustion chamber is connected with the flue gas inlet through a pipeline, and the air outlet is communicated with the interior of the combustor. According to the flue gas waste heat recovery cooker, the high-temperature flue gas generated through combustion in the combustion chamber and waste heat on the inner wall of the combustion chamber are used for secondary heating on oxygen-bearing air, so that the initial temperature of oxygen-bearing air entering the combustion chamber is greatly increased, fuel can be saved and the flame temperature can be increased; an interlayer is arranged in a heating cavity, the travel of high-temperature oxygen-bearing air in the heating cavity is increased, and the heat exchange effect of high-temperature oxygen-bearing air is improved; a waste gas treatment device is arranged, waste gas pumped out of an exhaust fan is absorbed and treated through waste gas treatment liquid, zero emission of pollutants is achieved, and environmental protection is achieved.

Description

technical field [0001] The invention relates to the field of kitchen and bathroom equipment, in particular to a stove for recovering waste heat from flue gas. Background technique [0002] Existing kitchen stoves have low combustion efficiency, high-heat flue gas escapes at high speed, and the heat conduction loss of the furnace wall is large, resulting in a great waste of energy and serious waste discharge. The energy-saving stoves on the market do not save energy significantly, and the exhaust gas is directly discharged into the atmosphere without treatment, which has a great impact on the surrounding environment. It is the most significant equipment in the stove with high energy consumption and high emissions. Contents of the invention [0003] The purpose of the present invention is to solve the above problems, and to provide a flue gas waste heat recovery cooker capable of recovering the heat energy of waste gas generated by combustion in the furnace, which is specifi...

AI Technical Summary

Problems solved by technology

[0002] Existing kitchen stoves have low combustion efficiency, high-heat flue gas escapes at high speed, and there is a lot of heat conduction loss on the furnace wall, which results in a huge waste of energy and serious waste discharge during combustion

The energy-saving stoves on the market do not save energy significantly, and the exhaust gas is directly discharged into the atmosphere without treatment, which has a great impact on the surrounding environment. It is the most significant equipment with high energy consumption and high emissions in the stove.
