Reheating furnaces After the continuous casting (see Fig. 1), the metal is split into slabs, billets or booms, which must be reheated in reheating furnaces up to 1250 Â°C before milling. An example of recent furnace, with digital control and lateral burners is shown in Fig. 3. Fig. 3. Example of reheating furnace for slabs, with lateral burners.

PDF Swirl Burner for Pulverized Coal Fired Reheating Furnace

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.

Combustion Using OxygenLancing in a Reheating Furnace

Using 100% O 2 as an oxidizer has been applied to batchtype furnaces for fuel economy. The 100% O 2 using combustion technology, however, has some disadvantages such as the corrosion of a furnace perimeter wall or high NO x concentrations in the case of the surrounding air intrusion into the batch furnace. However, the O 2 concentration in the combustion air is optimal near 30% because the ...
