At present, the combustion gas for being used to cook or fuel oil Chinese meal stove that hotel, restaurant etc. generally use, all can in use
Substantial amounts of high-temperature residual heat and high-temperature tail gas are produced, these high-temperature residual heats and high-temperature tail gas generally are had no to utilize direct from the chamber of a kitchen range
Surrounding and chimney in exclude, it not only causes the waste of energy, also result in the pollution to environment.
Through retrieval, in the prior art, Application No. CN200510102240.3 application for a patent for invention discloses a kind of ring
Guarantor's type energy-saving water heating system by recovering waste heat of air conditioner, including the outdoor heat exchanger provided with refrigerant inlet and refrigerant exit, outdoor exchange
Device includes heat exchanger, and heat exchanger is provided with refrigerant inlet, refrigerant exit, water inlet and delivery port, wherein, water inlet connection carries
The cold water pipe of cooling water, the water supply installation that delivery port can outwards be supplied water by recirculation return pipe connection.Due to through compressor of air conditioner
High temperature refrigerant after compression is cooled by cold water in a heat exchanger, and air-conditioning prevents hot gas from polluting without outwardly air heat release again
Environment；At the same time, cold water is heated to form hot water in a heat exchanger, and supply people live, needed for work, efficiently make use of

Circulating water pipe connects, and is provided with what is connected with circulating water pipe between the water inlet and the delivery port of steam-water separation water tank of waste heat exchanger
Water pump, steam-water separation water tank connect with steam pipeline.
However, above-mentioned do not account for the influence caused by aerator during range burner in the prior art.For example,
For the current unit that the crowd is dense boards and lodge and group, such as school, army, prison, hospital, dining room cooking stove heat waste and stream
It is extremely serious to lose phenomenon.Because the working method of dining room cooking stove is to be supplied with air blower as oxygen master, this mode causes largely
Heat losses.By taking a diameter of 80cm cooking stoves in dining room as an example, when cooking stove does not open air blower aerator, its thermal efficiency may be up to
More than 70%, but can not meet the needs of dining room is to firepower.Typically increase 550W, flow 20m3The aerator of/minute,
According to airflow balance principle, also can correspondingly be given off more than 20m out of burner hearth3600-700 DEG C of the high-temp waste gas of/minute.
Stove thermal efficiency now is only 40%, and the heat equivalent to 60% or so is discharged with high-temp waste gas.
