Combustion Using OxygenLancing in a Reheating Furnace

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 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.

Pulverized coalfired boiler Wikipedia

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.

Pulverized Coal Furnaces

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 ...
