Pass through return pipe joining water box.
By using above-mentioned technical proposal, the interlayer of Rose Box is provided with interlayer cavity, drop nitrogen filtered by water cooling
Device is cooled, because in discharge, for general temperature at 150 DEG C, cooling can form the condensation of impurity in also flue gas to flue gas
Water, so as to which further nitrogen effect drops in increase.
As the improvement of the present invention, smoke exhaust pipe includes horizontal part and vertical portion, and the horizontal part is provided with drainpipe, described
Drainpipe connects an exhausted bath box.
By using above-mentioned technical proposal, condensed water can be flowed back under gravity, and horizontal part is flowed to by vertical portion, by
In being provided with drainpipe on horizontal part, by drainpipe by the condensation water collection of backflow to exhausted bath box.
As the improvement of the present invention, the opening upwards of the free end of the horizontal part convex to form water fender.
By using above-mentioned technical proposal, in the condensation flow of the anti-backflow of setting of water fender to boiler.
In summary, the invention has the advantages that：It is enclosed in because blower fan is fixed in chamber, blower fan is to spray
Negative pressure can be formed during fiery cover delivery of fuel gas in chamber, now, is in communication with the outside by ventilation duct, combustion gas is existed with air
It is sufficiently mixed in chamber, burning is more abundant, plays the effect of energy-conservation, and the flue gas after burning is discharged out of exhaust duct, due to
Contain substantial amounts of nitrogen oxides in flue gas, and due to smoke exhaust pipe and chamber, a flue gas part is back in heater box
Combustion heating again, so as to reach control flame temperature, burning is set to be unlikely to too fast, the generation of such nitrogen oxides can also become
Few, the efficiency of flue gas recirculation is very high, and experiment shows, often reclaims 1/5th or so flue gas, the discharge capacity of nitrogen oxides can
To reduce a quarter, remaining flue gas can be discharged into air, and drop nitrogen filter is additionally provided with before air is put into, is made
Its secondary drop nitrogen, further reduces nitrogen discharge.
