What are the fuels of new energy boiler?

Common fuels for new-energy/clean-energy boilers

• Natural gas/LPG/LNG: Widely available, low SOx/PM, supports ultra‑low NOx with correct burner/controls. Often the fastest route to coal replacement.
• Electricity: Electric resistance or electrode boilers deliver zero on‑site emissions and near‑instant start/stop. Overall carbon intensity depends on the grid or on-site renewables.
• Biomass: Wood chips/pellets, agricultural residues. Renewable and often cost‑effective where supply chains exist; requires ash handling and fuel prep/logistics.
• Biogas/landfill gas/sewage gas: Renewable gaseous fuels from AD and waste streams; composition variability requires suitable gas treatment and burner design.
• Alcohol-based clean fuels (e.g., methanol, ethanol, DME): Low-sulfur, cleaner combustion; attractive where these fuels are abundant or incentivized.
• Hydrogen or H2‑blends: Zero-carbon at point of use; requires compatible burners/controls and attention to flame speed and NOx mitigation.
• Waste heat/heat recovery: Using high‑temperature process exhaust (kilns, furnaces, incinerators, glass/steel/chemicals) to generate steam or hot water without extra fuel.
• Thermal oil systems with clean fuels: Use gas, electricity, or biomass to heat thermal fluid for precise process temperatures where steam isn’t ideal.
• Geo/solar-assisted systems: Typically supplement rather than replace boilers, reducing the boiler’s duty when integrated with heat pumps or solar thermal.

How to choose

• Fuel availability and price stability
• Emissions limits (NOx, CO2, VOC, PM) and permitting
• Steam/hot-water load profile, pressure/temperature, turndown needs
• Space, electrical capacity, and utility interconnections
• O&M capabilities (ash handling for biomass, gas treatment for biogas, water treatment)
• Lifecycle cost and decarbonization roadmap (e.g., future switch to H2 or biogas)

ZOZEN Boiler recommendations by fuel/application

• Natural gas/LPG/LNG
  • WNS series gas/oil-fired condensing steam and hot-water boilers (horizontal, packaged). High efficiency, compact footprint, low NOx burners.
  • SZS series gas/oil-fired water-tube boilers for higher capacities/pressures and fast load response.
