Boiler burners are categorized based on the type of fuel they use, falling into four main groups: gaseous fuels, liquid fuels, solid fuels, and new energy/specialty fuels.
1. Gaseous Fuels (Gas Burners)
These offer clean, eco-friendly operation and high combustion efficiency, making them the primary choice for both industrial and residential boilers.
Natural Gas: The most common type, consisting primarily of methane (includes piped natural gas, LNG, etc.).
Liquefied Petroleum Gas (LPG): A mixture of propane and butane.
Manufactured Gas / Coke Oven Gas / Blast Furnace Gas: Industrial by-product gases or municipal gas.
Biogas / Landfill Gas: Combustible gases produced through fermentation.
Hydrogen and Hydrogen Mixtures: Emerging, clean, low-carbon or zero-carbon fuels.
2. Liquid Fuels (Oil Burners)
Characterized by high calorific value, these are frequently used for independent heating, large-scale industrial systems, or as a backup energy source.
Light Fuel Oils: Such as diesel or kerosene (feature good fluidity and are easily atomized).
Heavy Fuel Oils: Such as heavy oil or residual oil (highly viscous; typically require heating to reduce viscosity and facilitate atomization before combustion).
Alcohol-based Fuels: Such as industrial-grade methanol.
3. Solid Fuels (Biomass/Pulverized Coal Burners)
These offer relatively low costs and are widely used in small-to-medium heating systems or specific industrial and mining enterprises.
Biomass Pellets: Eco-friendly fuel pellets compressed from materials like wood chips, crop stalks, or rice husks.
Coal: Including bituminous coal, anthracite, and lean coal (typically pulverized for swirl or direct-flow combustion, or utilized via grate firing or fluidized-bed combustion).
4. Other / New Energy Fuels
Electricity (Electric Heating): Uses electric heating elements to heat the medium directly (commonly used in small electric boilers or thermal storage systems).
