A Powerful & Sustainable Heating Solution: Hot Water Biomass Boilers up to 1.5MW

Wood biomass boilers are heating systems that burn wood chips or wood pellets as a fuel to produce heat. Thay provide and efficient renewable energy solution for both small and large scale heating applications, making them well suited for a variety of uses in industrial processes, commercial buildings, and heating systems across New Zealand.

Wood chip biofuel is a type of solid biofuel made from chipped wood, typically sourced from forestry residues, wood processing waste or purpose grown energy crops. It is widely used for heat and electricity generation in industrial boilers, power plants, and district heating systems.

Wood pellet biofuel is a compressed biomass fuel made from sawdust, wood shavings, and other wood residues. It is widely used for heating and power generation due to its high energy density and efficient combustion.

Wood chips and wood pellets are both biomass fuels, but they differ in processing, efficiency, and cost. Wood chips are less processed, have higher moisture content, and are typically more affordable, making them ideal for large-scale industrial boilers. Wood pellets, on the other hand, are highly compressed with low moisture content, ensuring more efficient combustion but at a higher price due to processing. Fuel choice depends on heating requirements, budget, and system compatibility.

Businesses and institutions making use of wood biomass boilers benefit from several advantages:

1. Renewable & Environmentally Friendly Energy: Wood biomass are a carbon-neutral fuel source, meaning they release only the CO₂ that was absorbed during the tree’s growth. Unlike fossil fuels, wood biomass are sustainably sourced from forestry byproducts, reducing reliance on non-renewable resources while significantly lowering carbon emissions right here in NZ.
2. Cost-Effective Heating for Large-Scale Applications: Wood biomass is often more affordable than gas, diesel, or coal, particularly when sourced locally within New Zealand. Since they are a byproduct of our forestry and timber processing industries, their availability remains stable, reducing the risk of fuel price fluctuations.
3. High Efficiency & Performance: Modern wood boimass boilers operate at high thermal efficiency, often exceeding 90%, meaning they maximise energy output while minimising waste. These boilers also feature advanced combustion technology, ensuring efficient burning with low emissions and thereby contributing to a healthier environment for all Kiwis.
4. Automated Fuel Handling & Operation: Wood biomass boilers are designed with automatic fuel feeding systems, with integrated controls that store, transport, and feed wood chips into the combustion system as needed. This reduces manual handling and ensures a consistent, hassle-free heating process, perfect for large-scale operations in New Zealand.
5. Scalable & Customizable for Different Applications: With models ranging from small commercial units to large-scale industrial systems, wood chip boilers can be customised to meet your specific heating demands of a facility.

The operation of a wood biomass boiler follows a straightforward yet highly efficient process:

• Fuel Storage & Feeding: Wood chips or pellets are stored in a silo or bunker and are automatically transported to the boiler’s  stoker using a conveyor or auger system.
• Combustion & Heat Generation: A stoker automatically feeds the fuel into the boiler furnace, where it undergoes continuous combustion driven by radiant heat. Combustion controls regulate both the fuel supply and combustion air, optimizing burning efficiency to extract the maximum energy from the wood chips to produce thermal energy. The thermal energy produced during the combustion process is efficiently transferred to the boiler water though the boiler material. This process generates hot water, making it ideal for various commercial and industrial applications.
• Heat Distribution: The heated water is then circulated in a closed loop system that circulates heated water various points in a building, industrial facility and secondary processing equipment.
• Ash Collection & Cleaning: The minimal ash generated during the combustion process is gathered is in an easy-to-clean compartment. For enhanced convenience automated cleaning systems available, reducing maintenance requirements and ensuring smooth operation.

Wood biomass boilers are an excellent choice for any heating demands across New Zealand. They are particularly well-suited for:

• Industrial process heat.
• Hospitals and healthcare facilities.
• Schools, universities, and large educational institutions.
• District heating networks.
• Commercial buildings and office complexes.
• Agricultural and greenhouse heating.
