BIDRUM BOILERS- (AFBC & BFBC)
Emperor Bidrum boilers are the Process cum Power necessity
-
When air or gas is passed through an inner bed of solid particles such an sand supported on a fine mesh of grid, the air initially will seek a path of least resistance and pass upward through the sand.
-
With further increase in the velocity, the air bubbles through the bed and the particles attain a state of high turbulence
-
Under such conditions, the bed assumes the appearance of a fluid and exhibits the properties associated with a fluid and hence the name “Fluidized Bed”.
These type of boilers can easily take the variation of load fluctuation without affecting the Overall performance & efficiency of the boiler.
Operating Range
-
Capacity: 8 to 25 TPH
-
Firing Mode : Fluidized bed Combustion ( AFBC,BFBC with over bed & under bed)
-
Pressure : Upto 32 Kg/cm2(g)
-
Steam Temperature: Saturated & super heated upto 380° C
-
Fuel : All type of Coal/ Rice Husk/ Lignite/Agro waste/ Wood chips
-
Application: All process heating Industries like Co generation Power plants, Process plants as Paper, Food Process, Rice Mill, Rubber Pharmaceutical, etc.
Special Features
-
Extreme precise optimum fluidization velocity, optimum resistance time & free board height, which leads to instant steam generation
-
For very high ash fuels like Dolochar, washery rejects, etc. Open/Hopper bottom type furnace can be given
-
Multi fuel firing
-
Special drum internals High sulphur, high ash and low CGV fuels can be burnt.
-
Minimized un burnt carbon loss and hence high boiler efficiency.
-
Compartmentalized combustion chamber. Hence better turn down ratio of 1:4.
-
High turbulence of the bed facilities quick start up and shut down.
-
Low SOX and NOX emissions.
-
Under bed and over bed feeding options
-
All necessary safety interlocks for safest operation
-
Very effective steam generation since boiler is designed with suitable evaporation areas for bed coil, water wall, bank tubes.
-
The well-built design effectively brings down maintenance needs that in turn ensure uninterrupted operation.
