WNS Series of horizontal internal combustion boiler is the boiler hull type horizontal tri-backhauling internal combustion boiler designed by our technical professionals according to the advanced technology from home and abroad combined with practical experiences. The boiler is fully automatic, the fuel after atomization by the burner forms the flame filling the whole waveform furnace, and via furnace wall to transfer the radiant heat, this is the first backhaulting. The high temperature smog yields from combustion is concentrated inback combustion chamber and turns to the second backhauling, i.e.,whole pope bundle area; After heat exchange by convection, the smog temperature gradually lowers and goes into the front smog chest, and there turning to the third backhauling, i.e.,bare pipe bundle area, and then passes through rear smog chest to chimney, and funally exhausts to the atmosphere.
This series of products are safe, reliable, efficient, energy-saving environmental protection, maintenance convenient, durable, automatic intelligent control, etc.. All the performance indexes are higher than the design requirements, and have reached the advanced level of domestic and international.
key processing technology like material preparation of steel tubes, circling, drilling of tube plate, etc are all adpot advanced CNC machining process to decrease the assemble stress and extend the boiler working life.
The front and rear somke chamber panel adopts CNC plasma cutting machine to cut orderly and beautifully.
The boiler vertical and circular seam adopts advanced unionmelt welding process to ensure the welding quality. All the vertical and circular seams will be done 100% radiographic inspection.
The weld of smoke tube and tube plate will be pre-expanded first to remove the gap between tube and tube plate. And then adopt argon arc automatic welding process. This may relief stress effeciently and extend the boiler woking life.
Adopt high-class aluminium silicate fibre. Use refractory mortar to keep the furnace temperature under 45° and control heat loss effeciently.
Font and rear smoke chambers are filled with multilayers of aluminium silicate fibre and be insulated by high temperature refractory mortar. This may increase thermal resistance and decrease heat loss effeciently to improve heat efficienct.
Asufficient steam stoage and heating surface make the boiler to generate bigger thermal power and high quality steam output.
The smoke chamber door is hinge structure and open like window so that it is easy to maintain, detect and clean.
This series boiler adopts whole corrugated furnace.
Reinforce the disturbance of flue gas as well as improving the heat transfer effect of unit area and unit volume effectiently.
Increase the strength and elasticity of furnace. Prevent the pressure parts from being damaged because of the increase of stress effectiently during the thermal expansion procedure.
Add condensator. Use the waste heat of flue gas exhausted from the end of boiler to increase the water inlet temperature and decrease the exhaust gas temperature. This makes the boiler heat efficiency reach above 98% and save the operating cost;
Condensator adopts finned tubes to increase heating area, heating transfer efficiency and decrease the volume;
Finned tube adopts ND steel or stainless steel to avoid low temperat¬ure corrosion of steel.
Fully automatic operation, combustion、water level、 temperature and steam pressure are adjusted automatically and self protected.
Advanced manufacturing process. Adopt assembly line automatic spinning work;
Strengthen heat transfer to improve boiler heat efficiency;
Thread smoke tube is efficient heat transfer component researched by our company for years. After constantly optimization, the selection of thread groove depth and pitch could reach the following result: when meeting the lowest flow resistance, heat transfer coefficient is 1.2 times higher than common smoke tube.
