Circulation fluid bed Hot Water Boiler
fuel：coal/biomass
capacity ：10-100t/h
usage：supply steam/power plant
Introduction :
The circulating fluidized bed hot water boiler[1] is the latest generation of patent product developed by Henan province sitong boiler co., ltd. This product adopt the latest advanced CFB technology, [2] the structure of boiler film heating surface and parallel baffled of convection tube. So the boiler is more reliable, simple, compact as a whole. The boiler body consists of coal feeder, combustion equipment, water cooling system, high temperature cyclone separator, economizer, steel, appendage, furnace wall, etc.
Structure feature
1. This series boiler adopts whole steel structure on floor, greatly save the investment of boiler basic construction . The boiler has a low thermal inertia, pressurization and air supply time is fast.
2. Hanging membrane wall furnace adopts the structure of diaphragm wall light tube furnace wall which have the feature of reliable collision avoidance, tight sealing, best performance of heat transfer.
3. Lower supporting part of fluidized bed using the structure of all steel shell heavy furnace with tight sealing and simple structure.
4.The upper chamber and lower fluidized bed adopt the expansion structure with reliable connection and sealing.
5. Heat-resistant alloy cast steel bar embedded countercurrent cap to achieve dust-tight, even air distribution and long service life.
6. The most reliable and mature dual cyclone separator match with diaphragm wall insulation water-cooled tent and smoke chamber structure with diaphragm wall water cooling tent.
7. Double drum, multipass, vertically washing convection bank can eliminate the convection bank plugging ash and abrasion.
Advantage:
1. Widely burning adaptability.External circulating fluidized bed boiler can burn high quality coal, also can burn inferior coal. Combustion technology is environmental protection.
2. Simple feed back system, high combustion efficiency.
High temperature material under the entrainment of air get into material collector, the collected material enter into back feeder, then through return feeder back to the combustion chamber. Through multiple circulation burning, the combustion efficiency is very high.
3. Large range of load regulation, rapid load change ability. And in the bed does not put the heating surface of immersed tubes.
