What type of fuel is often used in industrial boilers?

Natural gas is commonly used in industrial boilers due to its efficiency, availability, and cost-effectiveness. It burns cleanly and produces high temperatures necessary for various industrial processes, making it a preferred choice for many facilities. Additionally, natural gas systems can be integrated with existing infrastructure, allowing for easier upgrades and maintenance.

Wood pellets, while a renewable source of energy, are less common in large industrial applications compared to natural gas due to limitations in scalability and efficiency for high-demand situations. Solar energy, although a sustainable option, generally requires significant space and investment in technology that may not be viable for all industrial operations. Electricity, while a clean energy source, is often more expensive and less efficient for large-scale heating processes when compared to direct natural gas heating. Thus, natural gas remains the most practical and widely used fuel in industrial boiler applications.
