EFFICIENT AND SAFE OPERATION OF POWERPLANT AND PROCESS BOILERS
PARAMETERS REQUIRED TO BE MAINTAINED STRICTLY FOR EFFICIENT OPERATION OF AFBC BOILERS — Bed Height/FD Air Pressure — Primary Air Pressure — Bed Temp./Furnace Temperature — Fuel Size — Bed Material size & Specifications — Air & Fuel ratio — BED HEIGHT/FD AIR PRESSURE — Static height for AFBC Boiler is to be maintained 300 to 325 mm during initial light up of boiler. — Expand bed height for AFBC boiler is to be maintained 500 mmwc to 600 mmwc. — FD Air discharge Pressure is to be maintained 600 to 650 mmwc. — Wind box or Air Box pressure is to be maintained 500 to 600 mmwc. NOTE: High W.B. pressure increases the erosion of bed coils & low W.B. stops fluidization. PRIMARY AIR PRESSURE — P.A. fan air header pressure for AFBC boiler is to be maintained 1000 to 1150 mmwc. — Difference of primary air pressure & F.D. wind box pressure is to be maintained approximately 500 mmwc. NOTE: High P.A. pressure increases the bed coil e
