What type of fuel is most commonly used in power boilers?

Natural gas is the most commonly used fuel in power boilers mainly due to its efficiency, lower emissions, and cost-effectiveness compared to other fuel types. It burns cleaner than coal and oil, producing significantly fewer pollutants such as sulfur dioxide and particulate matter, which makes it more environmentally friendly.

Moreover, the infrastructure for natural gas has expanded in recent years, allowing for easier access and delivery, which increases its practicality in many regions. Natural gas power boilers are also capable of achieving high efficiencies and can respond quickly to changes in power demand, making them a flexible option in modern energy systems.

While coal, diesel oil, and biomass have been traditional fuel sources, they generally have higher carbon footprints and face more regulatory challenges due to environmental concerns, which makes them less favorable in current power generation practices.
