Fossil Fuel Fired Boiler Plant Configuration

For fossil fuel fired boilers this requires a very large furnace in which to burn fuel at a high mass flow rate. The fuel, whether solid or liquid, has to be finely divided and mixed with air to promote rapid combustion. For coal fired plants, the coal must be pulverised to a fine powder in suitable pulverising mills.

Typical Causes of Slagging and Fouling Problems in Boilers

The No. 1 cause of furnace slagging is low furnace oxygen content. Most boilers are designed for 115% to 120% theoretical combustion air. This is generally expressed as 15% to 20% excess air. For coal furnaces, the oxygen levels would be 3% to 3.8%.

Lean and clean: why modern coal-fired power plants are

Jun 21, 2016 · At the heart of coal-fired electricity generation lies the steam cycle. Typically, pulverised coal is fed into a giant industrial furnace surrounded by boiler tubes filled with water. The burning coal heats the water to create steam, which is transferred at high-pressure to turbines linked to a generator.
