Which fuel source is commonly used in steam boilers?

Natural gas is a commonly used fuel source in steam boilers due to its efficiency, availability, and cleaner burning characteristics compared to other fossil fuels. When burned, natural gas produces a high flame temperature and a significant amount of heat energy, which is essential for generating steam efficiently. This efficiency translates into lower operational costs and reduced greenhouse gas emissions, making natural gas a preferred choice in many industrial and commercial applications.

Additionally, natural gas systems can be easily controlled and adjusted to meet varying load demands, which is vital for maintaining the desired steam output. The widespread infrastructure for transporting and distributing natural gas also contributes to its popularity as a fuel source in steam boiler operations. Other fuels such as coal or wood pellets may still be used, but they often come with higher emissions and operational complexities.
