In order for a boiler to convert water to steam, a fuel source must release its energy in the form of combustion in the boiler furnace. Fuel systems play a critical role in the performance of a boiler. The most commonly used fuels in power boilers are natural gas, fuel oil, coal, and wood (biomass). Each of these fuels have different physical properties that require delivery systems that are unique to that fuel. Fuel systems should be properly operated and maintained to run efficiently.
