What are the most common boiler fuel types?

Boilers are often distinguished by fuels that power them. The kind of fuel makes an essential difference in operating costs and environmental impact, so it’s important to learn about the various types of boiler fuel.
Coal, is a common boiler fuel. It dominates the global energy arena due to its abundance, affordability and wide distribution across the world. The most commonly used coal fuels include anthracite, bituminous coal, sub-bituminous coal, lignite and peat.
There are also a large number of gas/oil fired boilers. Natural gas, for instance, contains a mixture of several substances, including methane, propane, and butane. Meanwhile, oil-fuel boilers may require diesel, gasoline, or other types of petroleum-based fuels.
Finally, some boilers choose biomass as fuel. These are less common fuel types applied by environmentally progressive companies that utilize items like wood chips, rice husks, and various plant materials that surprisingly can be used to fuel boilers.
When it comes to selecting a boiler based on the fuel it uses, it’s best to find a boiler that can operate on more than one type of fuel.Meanwhile, ZOZEN’s WNS series of boilers can run on natural gas, biogas, of #2 fuel oil, giving you several fuel options.
One of the top benefits of a boiler that can run on multiple types of fuel is that it can help you to make adjustments to changing fuel costs. Prices can fluctuate so much that it's sometimes difficult to commit to one type of fuel all the time. When it comes to fuel for your boiler, it's always best to have options.
