Incomplete Combustion in Coalfired Power Plants

Incomplete combustion occurs in a coalfired unit's furnace when insufficient oxygen (O 2) is available during fuel combustion. "Excess Air" is the amount of O 2 available for combustion. Coal requires a relatively high amount of excess air to burn completely, quickly, and in the furnace compared to other types of fuel.

How a Coal Plant Works

How a Coal Plant Works. Coalfired plants produce electricity by burning coal in a boiler to produce steam. The steam produced, under tremendous pressure, flows into a turbine, which spins a generator to create electricity. The steam is then cooled, condensed back into water and returned to the boiler to start the process over. Here's a real ...

A coalfired power plant converts the stored chemical energy in the coal to thermal energy by burning it. That thermal energy produces steam which spins turbines (turning it into kinetic energy) for giant generators. These generators produce the electricity we use. Coal to Electricity Process The first step is unloading the coal from the train.
