Depending on their design and intended application, boiler burners primarily utilize four major categories of fuel: gaseous fuels, liquid fuels, solid fuels, and new/alternative energy fuels. Different types of fuel require specific, dedicated burners—or, in some cases, multi-fuel burners capable of handling various fuel types.
The following is a detailed classification of fuels and their common varieties: 1. Gaseous Fuels (Gas Burners): Clean and environmentally friendly, these fuels boast high combustion efficiency and currently represent the mainstream choice for both industrial and residential boilers. Examples include: Natural Gas (the most widely used), Liquefied Petroleum Gas (LPG), Manufactured Gas / Coke Oven Gas, and Biogas.
2. Liquid Fuels (Oil Burners): Characterized by high calorific values, these fuels are frequently employed in independent heating systems, large-scale industrial facilities, or backup power systems. Examples include: Light Fuel Oils (such as diesel and kerosene); Heavy Fuel Oils (such as heavy oil and residual oil—which are typically highly viscous and require preheating to facilitate atomization and combustion); and Alcohol-based Fuels (such as industrial methanol).
3. Solid Fuels (Biomass/Pulverized Coal Burners): These fuels offer relatively low costs and are widely utilized in small-to-medium-scale heating systems or specific industrial sectors. Examples include: Biomass Pellets (compressed from materials such as wood chips and straw, constituting an eco-friendly solid fuel source); and Coal (such as bituminous coal, anthracite, and lean coal—which typically requires pulverization into fine powder for use in swirl or fluidized-bed combustion systems).
4. New and Alternative Energy Fuels: As environmental regulations become increasingly stringent, a growing number of novel fuels and dual-fuel combustion systems are being deployed. Examples include: Hydrogen (a clean energy source with zero carbon emissions); and Dual-Fuel Burners (capable of seamlessly switching between liquid fuel and gaseous fuel, thereby ensuring the stability and reliability of the energy supply).
