Pulverized coal (pulverized fuelpf) has been fired in rotary cement kilns (see Kilns) and boiler furnaces (see Boilers).The latter are basically boxes lined with tubes in which water is evaporated and contain a water/steam mixture. The coal is pulverized to a fine powder, usually so that 70% is less than about 75 μm in size, before being carried by part of the combustion air stream to the ...

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 ...
