Furnace body inner cavity, the combustion air being pumped into through air pump enter heat exchanger through cold air pipe, burner are entered from warm-air pipe after heat exchange
As the combustion-supporting gas of combustion gas, a part of channeled air that cold air pipe distributes introduces desorption tube via flue gas injection air hose, high
Fast outer row forms negative pressure, to make the flue gas in furnace body automatically into the cigarette to heat exchanger to the exhaust gases passes of heat exchanging device
Gas channel forms contactless heat exchange with the air for entering heat exchanger, and the flue gas after heat exchange continues natural under the action of negative pressure
Entering desorption tube through pharyngeal canal to arrange with outside channeled air, the negative pressure value that channeled air gas velocity is more formed in exhaust gases passes is bigger,
Correspondingly, the flow velocity of flue gas is also improved, and flue gas enters the power of heat exchanger also with regard to bigger, the flow velocity of flue gas and cold air
The mutual positive association of intake velocity.
Preferably, it is provided with switch valve on flue gas injection air hose.
Preferably, according to from lower to upper air-flow move towards, the desorption tube mainly include pharyngeal canal, along airflow direction caliber by
The big conical pipe of gradual change, section pipe, straight tube, channeled air have larger flow velocity in desorption tube,.
Preferably, cold air pipe, warm-air pipe, flue gas injection air hose are all made of the broken pipe of transverse tube and vertical tube composition.
Compared with prior art, the utility model has the advantage of：It is split type from pre- to provide a kind of active ventilation formula band
The heat exchanger of the seam heating furnace of hot burner, preheating is active ventilation formula, itself has certain negative pressure that can attract flue gas, makes
Flue gas enters heat exchanger and carries out heat exchange, reaches control furnace pressure and reduces flue gas loss, warm-up combustion-supporting air, energy-saving effect
Fruit.What combustion air used simultaneously is pre-heated, helps to improve the fuel value of fuel, reduces energy consumption.
