Difference Between AFBC Boiler and CFBC Boiler AFBC ...

1. Velocity. AFBC= 1.2 m/sec to 3.7 m/sec CFBC= 3.7 m/sec to 9 m/sec. 2. Heat Transfer Surface. AFBC= Heat is extracted within the the bed CFBC= Heat transfer occur outside of combustion zone i-e Convection section water walls and at the exit of the riser. 3. Size of Coal. AFBC: 6-10 mm CFBC: 6- 12 mm. 4. Combustion Air Supply. AFBC: 3 - 5 psig CFBC: 1.5 - 2 psig

Mar 17 2015 · Steam Boiler and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.

The air path was divided in three ways around the outside of the swirler through the air swirler and a small amount inside the cap plate over the atomizer. Data was obtained for two different spray angles 60 ~ and 80 ~ at the full power rating of the burner which was approximately 1 ton/hr.

The velocity of air leaving the compressor is 100 m/s. Neglecting the velocity at the entry of the compressor determine the power required to drive the compressor if the mass flow rate is 15 kg/sec. Take Cp(air) = 1 kJ/kgK and assume that there is no heat transfer from the
