The WNSXXXXQY series fullautomatic oil (gas)fired steam boiler ,the structure all adopt to annoy three return journeys ,
undee hearth whole wet back .the fuel is combusting under tiny pressure in a hearth ,the hot smoke follows a heath
back ward through return to room of combustion into the first smoke way controls through oppressing ,the smoke turn
of type 1800, and go in the second to smoke tubes,rear row to go into the atmosphere after changing the heat
through convection .To use the design thoughts of the three return journey symmetry structure ,three return journey
steam boiler with bigger capacity . Biggest characteristics in this kind of inside the structure of the canister and the
partiality fire box .it is advantageous to improve on the enough radiation area to be subjected to the hot side .But the
convection is made up of fire tube the second return journey and three return journey. Returning room of fire
connect with the plank and a hearth conjunctions, the back plank adoption spheroid to seal ,the head and tube after
returning room of fire plank .The returning smoke room of the second return journey and the third return journey
turned the smoke room to constitute the smoke box , here temperature of smoke id already lower than 5000Cs.
Therefore ,fire-proof of the smoke box adopt light form of the structure .
Flue add condenser at the end
Rear flue additional condenser Additional rear flue condenser using flue gas condenser absorbs latent heat and sensible heat , improving the water temperature of the boiler , reducing the exhaust gas temperature, the thermal efficiency of the boiler increased to more than 98%.(Note: The process of using the boiler ,condenser out of the water valve must be normally open).
