Gasification of fuels as a highly efficient and low-emission way of generating energy from biomass
PolyHeld delivers an exceptionally efficient heat supply solution, catering to low output ranges from 400 kW to 3 MW. By integrating a counterflow gasifier and precision staged combustion, we attain efficiencies surpassing 92%. Its unique design eliminates the need for supplementary flue gas cleaning, leading to substantial savings in operational costs. Notably, the PolyHeld system boasts an outstanding partial load capacity of as low as 25%. The PolyHeld system is particularly suitable for generating warm water, hot water and steam as well as for heating thermal oils.
Fuel versatility: wood and forestry residues and most woody fuels (with a moisture content of up to M45)
Efficiency: >92% (a 5% improvement over traditional systems)
NOx: 25% lower than conventional systems
Dust: <20mg/Nm3; 11% O2 (without additional exhaust gas cleaning)
Output range: 25-100%
Low maintenance costs
The cornerstone of the ReGaWatt-developed Kombi Power System is its counterflow gas generator, capable of delivering thermal outputs of 990 kW to 20,000 kW. This robust and durable gasification technology boasts numerous advantages:
Extensive fuel versatility: biogenic residues such as waste wood, screenings and bark
Capable of operating at part-load (as low as 20%) and adjustable within minutes
No pre-drying necessary (w30 – w55)
Complete burnout = clean ash
With its modular design, the Kombi Power System offers customisable solutions tailored to each customer’s requirements, facilitating the versatile production of power, heat, cooling, steam and synthesis gas for direct gas utilisation. Additionally, it yields bio-oil with a calorific value comparable to heating oil, ideal for heat generation and temporary storage to offset peak demands (can be stored for up to 6 months).
