enrichment level and lance location inside a blast furnace tuyere are also highlighted. INTRODUCTION. The iron blast furnace uses carbon as a fuel to meet the energy requirements of the process as well as a reducing agent for smelting the iron ore to pig iron. The most widespread form of carbon used for this purpose is metallurgical coke.

Reheat furnaces heat the slabs to about 1200 °C, which makes the steel suitable for hot rolling. During this reheating process temperature uniformity within the slab is very important. A detailed understanding of the reheating process is hence, important both from the perspective of product quality and energy use.

In most of the SRRM units, a 4inch pipe is used as a burner for pulverized coal. This 4inch pipe is inserted into the front and side walls of the reheating furnace. Only primary air in ambient temperature is used for combustion in such conventional burners and the airfuel ratio is neither monitored nor controlled.

The most important concern regarding the use of coal combustion in transient processes, as encountered in reheating furnaces, is the justifiable compromise between computational expense and accuracy. Further, to the authors' knowledge, very few works have been reported for simulation with pusher type reheating furnaces [19].
