What type of fuel is most commonly used in boilers?

Natural gas is the most commonly used fuel in boilers due to its advantages over other fuel types. It burns more cleanly than coal and oil, producing fewer emissions of harmful pollutants such as sulfur dioxide and particulate matter. This characteristic makes natural gas a preferable choice in emission-controlled environments and places with stringent environmental regulations.

Additionally, natural gas is often available through established pipeline infrastructure, allowing for convenient and efficient delivery to facilities. Its high energy content and ease of combustion contribute to more efficient operation in various types of boilers, making it an optimal choice for both industrial and residential applications.

While coal, electricity, and oil are also utilized as fuel sources, they present various challenges, such as higher emissions, greater storage needs, and fluctuating costs. Therefore, the widespread adoption of natural gas for boiler operations aligns with trends towards cleaner energy and efficient heating practices.
