The use of multiple types of fuel in boilers is essential for ensuring flexibility and efficiency in different applications. Boilers can be designed to operate on various fuel sources including gas, oil, coal, and biomass, making them adaptable to both residential and industrial settings.

Gas and oil are common fuels due to their relative ease of use and high-energy content. Coal, while less favored in some regions due to environmental concerns, still plays a significant role in power generation and industrial processes. Biomass, which includes organic materials like wood, agricultural residues, and other biological products, is gaining popularity due to its renewability and lower emissions.

Electricity and solar energy, though mentioned as alternative energy sources, do not traditionally fall under the category of fuel types that are directly burned in a boiler to produce steam. Instead, these are more often used in electric boilers or solar thermal systems, which operate differently from conventional fuel-burning boilers.

By encompassing a broad range of fuel options, boilers can meet varying energy demands while supporting sustainability goals. This versatility is why the selected answer is accurate.
