4000kg 4 ton industrial biomass coal fired steam boiler prices for rice mill
new DZH biomass steam boiler is a single fire tube boiler.The combustion equipment is movable grate.The water cooling walls on the left and right sides of the furnace are radiant heating surfaces, and the flue pipes on the two wings and the threaded flue pipes in the pot barrel are convective heating surfaces.The front and rear furnace walls and the water cooling walls on both sides are constructed with firebrick.
The technology of arched tube plate and threaded flue pipe is adopted to solve the problems of tube plate crack, drum bulge, low thermal efficiency and poor fuel quality adaptability of shell boiler.
Structure
Combustion process:
The fuel enters the furnace and burns on the grate. The flue gas from the production enters the convection tube bundle on both wings along the bottom of the boiler barrel through the smoke outlet on the middle partition wall, enters the threaded smoke pipe through the front smoke box, passes through the dust collector, and is pumped and discharged into the atmosphere through the chimney by the induced draft fan.
Technical characteristics
1. Reasonable smoke speed design, the heated surface does not accumulate dust, does not wear, the boiler heating surface can maintain high efficiency, full load and safe operation for a long time under the condition of no soot blowing.
2. All independent circuit design, for the hot water boiler also uses a reasonable ejector cycle, the medium flow rate in the heating surface circuit is higher than the national standard requirements.
3. Inertial separation of soot from the boiler furnace outlet, effectively reducing the dust concentration of the exhaust and reducing the wear on the rear heated surface.
4. Compact structure, smaller installation volume than other types of boilers of the same capacity, shortening the installation period and reducing the cost of the boiler room.
5.The boiler has a large volume of water, which is conducive to power failure protection and has a strong ability to adapt to load changes.
