Reheating furnace in steel plants Steel that is transported from a production plant to another location, for instance a facility for annealing, requires reheating as they are transported cool. The two reheating furnaces at SSAB operate at a rate of 300 t/h of steel and at MW. The steel is rolled in from one end of the

The injection of pulverized coal was introduced at blast furnace 9 in December 2015. In November 2016, the pulverizedcoal consumption reached kg/t, with coke consumption of kg/t of hot metal. Technical constraints have prevented higher levels. Since both technologies are in use at blast furnace 9, various comparisons are possible.

The finer the grinding of coal, the more efficient its combustion. The total time required from entry of a coal particle to a furnace to combustion of the particle is very short. This time, however, is dependent on various factors. The heart of a pulverized coalfired boiler is the pulverizer, also known as the mill.

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.

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.

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.

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.
