Jenbacher gas engines – Overview 1
A leading manufacturer of gas-fueled
reciprocating engines for power
generation.
• Power range from 0.25MW to 3MW,
4 platforms / 10 products
• Fuel flexibility: Natural gas or a variety of
renewable or alternative gases
(e.g., landfill gas, biogas, coal mine gas)
• Plant configurations: Generator sets,
cogeneration systems, container solutions
• Delivered engines: about 8,000 units / 9,000 MW

Experiences with Wood gasification
•Harboore / Denmark;
Woodgas; H2: 15 - 18%; CO: 25-28%; LHV = 6.8 MJ/Nm³
•Güssing / Austria
Woodgas; H2: 35 - 40%; CO: 20-25%; LHV = 10.5 MJ/Nm³
•Spiez / Switzerland
Woodgas; H2: 12 - 15 %; CO: 18-20%; LHV = 5.4 MJ/Nm³
•Kokemäki / Finnland
Woodgas; H2: 15 - 18%; CO: 18 - 20%; LHV = 6.1 MJ/Nm³
•Skive / Denmark
Woodgas; H2: 15 - 18%; CO: 18 - 20%; LHV = 6.1 MJ/Nm³

Crucial points in the utilization of
wood gas
- Gas cleaning technology
- Fulfillment of emissions
Installed woodgas plants

Summary
wide range of H2 gases can be used in gas engines
key factor is laminar flame speed
main technical barriers:
gas contamination (tar, humidity....)
CO- emissions
