ABSTRACT
The cupola is a refractory lined shaft furnace and the basic fuel is coke. The main objective of the present work is the utilization of waste material (Rice husk briquette) of low C.V. to 50% eq. of split coke charge. Bed coke remains unaltered due to breakdown of rice husk briquette on heating in a cupola. The experiment was carried out in a single blast cupola 23-inch internal diameter (ID). Four charges were tested out of eight charges. There was no change in composition, melting rate, spout temperature, and slag chemistry, but SO2 emission was reduced to 23.13%. Some smoke is coming through charging door due to high volatile matter (60%), which may be overcome by introducing excess O2/Divided Blast Cupola.
