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.

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 °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.

A pulverized coalfired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup) that is blown into the firebox.. The basic idea of a firing system using pulverised fuel is to use the whole volume of the furnace for the combustion of solid fuels.

For a reheating furnace, an analysis of thermal efficiency depends on precise investigations of the combustion and flow characteristics inside a furnace. Especially, the flow field of the hot gas has significant influence on heating slabs. The slabs are heated up to the temperature over 1500 K, and then they are transported to the rolling mill.

Using O 2 as an oxidizer has been applied to batchtype furnaces for fuel economy. The 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 ...

The ultimate and proximate analysis of the fuel used for CFD modelling purposes is shown in Table 1 along with the fuel particle size distribution. The actual plant fires the fuel at a 99 % maximum continuous rating (MCR) with an excess air ratio of %.As the plant turns down from full load the excess ratio is increased to ensure sufficient air and fuel mixing in the furnace.
