Product synopsis:
 
This product is a horizontal single drum longitudinal layout three return fire and water tube boiler, furnace tube light on both sides of water wall and airfoil flue, drum inside decorate a group of pipe, boiler drum, induced draft fan with mechanical ventilation, using small scales grate combustion equipment, especially suitable for combustion of biomass granule.
Fuel since the vibrating feeder vibration feeding, after burning flame, through the back wall to combustion chamber, state upwards into the airfoil flue, then the former smoke box thread smoke tube, and then through the economizer (optional), air preheater (optional), dust catcher by induced draft fan smoke again to the chimney into the atmosphere.
 
Product use:
Biomass steam boiler is mainly used for saturated steam.
 
 
Product advantage:
 
1, through the header on the two sides are part of the riser pipe to protect the chamber, then introduce the drum side lower part supplemented by drum at the bottom of the heat insulation of integral casting molding top heating surface, with novel furnace structure successfully solved the drum at the bottom of the direct flame radiation under high temperature, avoid to produce the "bulge" defects.
 
2, the two wings of flue Settings, smooth flue gas in the top smoke box, make the tube plate temperature is the same as before, to avoid the tube plate cracking due to thermal stress.
 
3, drum in return by the single threaded pipe, enhanced heat transfer effect, threaded pipe has since soot cleaning function at the same time, to avoid the smoke tube soot formation.
 
4, 10 t/h boiler series before and after the arch adopts the whole structure of the water wall tube as support, the formation of permanent arch. Low and long after the arch, export to tilt, arch Angle 45 ° before and after the arch photograph echo, obvious "alpha" flame, is advantageous to the inferior coal combustion and coal adaptability is strong.
 
5, grate side sealing structure of advanced design is reasonable, avoid the side seal card grate and grate wind uneven and burn out side seal on both sides of the cloth defects. And 4 t/h boiler use sealing side of cold plus Angle of the plate reinforcing bar structure, more than 6 t/h boiler seal structure under the contact side sealing.
 
6, are independent regulation under the fire grate wind room, into the wind on both sides; Adopt new crank arm screw adjusting structure, so that the air venting area ratio reached 100%; Flexible adjustment, cloth uniform wind. Design push-pull type damper soot cleaning device, gate of heat-resisting cast iron finishing sealing structure, so as to effectively prevent the deformation of the secondary combustion and grate air leakage.
