  • Bituminous: Soft coal is often used for electric power generation and steel production. Caloric Value (BTU/lb): 17,000 – 24,000.
  • Lignite: Lowest rank of coal with the highest moisture content. It’s used for electricity production. Caloric Value (BTU/lb): 9,000 – 14,000.

Storing coal may not be exciting, but it’s where all the thrill is!

Coal Storage and Preparation

Coal storage and preparation are essential before combustion. To guarantee fuel quality, it must be stored properly and go through a cleaning process.

  1. Coal arrives by truck or train and is placed in a storage facility near the power station.
  2. The coal is then put into large stockpiles, usually on the ground.
  3. In order to burn, the coal is crushed and blended with water, creating a slurry.
  4. This slurry is filtered to remove rocks, dirt, and other impurities.
  5. The cleaned slurry is sent via conveyor belts or pipelines to the power station for combustion.

The quality of the fuel entering the combustion chamber is dependent on the preparation beforehand. Different coal forms require different preparation methods, such as coal for steel production needing more heating than coal for electricity generation. We can observe that, despite all the technological changes, the principles of storing and prepping fuel stay the same.

The combustion of coal is intense – it’s hot but not always pretty.

The Combustion Process of Coal Furnace

The combustion of coal in a furnace is all about the heat. As this fossil fuel is rich in carbon, it releases tons of energy when burned. Flames heat up air or water that flows through the furnace.

Sadly, burning coal also releases some nasty gases like sulfur dioxide, nitrogen oxides, and carbon monoxide. To protect our environment, furnaces have measures to limit their emissions.

To get the most out of the combustion process, temperature, airflow, and fuel quality must be kept under control. Furthermore, regular maintenance is key, as cleaning ash and inspecting components can help avoid breakdowns and optimize efficiency.

In conclusion, understanding the combustion process of a coal furnace is essential for utilizing its benefits successfully and promoting better energy production and conservation.
