Industrial fuels are energy sources used primarily in manufacturing and production processes. These fuels include coal, natural gas, oil, and biomass, which provide the necessary energy for machinery, heating, and power generation. They are essential for industries such as steel production, cement manufacturing, and chemical processing. The choice of industrial fuel can impact efficiency, cost, and environmental sustainability. For instance, natural gas is often favored for its lower emissions compared to coal, while biomass is considered a renewable option. Understanding the properties and applications of these fuels helps industries optimize their energy use and reduce their carbon footprint.
