Blast Furnace RAFT

"

I Want The Formulae For RAFT calculation For Blast Furnace With or Without PCI.

And What Are The Ways through which we control RAFT of the furnace."

YOU ARE ASKING A BASIC QUESTION???

RAFT-RACEWAY ADIABATIC FLAME TEMPERATURE

DIRECTLY PROPORTIONAL TO- HOT BLAST TEMP, OXYGEN INJECTION

INDIRECTLY PROPORTIONAL TO-COAL INJECTION, STEAM INJECTION, OIL INJECTION

RAFT PUT ON AUTO CONTROL MODE WILL MATAIN FURNACE AT STABLE OPERATION AS THE FLAME TEMPERATURE IS ALWAYS PUT CONSTANT.

FLUCTUATING FLAME TEMPERATURE WILL MOVE THE DRIPPING & COHESIVE ZONE INTURN RESULTING IN UNSTABLE FURNACE
