Fossil Energy Study Guide 300 Million Years Ago

Th e process of converting coal into electricity has multiple steps and is similar to the process used to convert oil and natural gas into electricity 1. A machine called a pulverizer grinds the coal into a fi ne powder. 2. Th e coal powder mixes with hot air, which helps the coal burn more effi ciently, and the mixture moves to the furnace. 3.

How How Is Coal Controlled Or Processed

The major emission source in the fine or coarse coal processing phases is the air exhaust from the air separation processes (air tables). For the dry cleaning process, these emissions are generated when the coal is stratified by pulses of air. Particulate matter emissions from this source are normally controlled with cyclones followed by fabric ...
