At a wood energy conference in Alaska last week it occurred to me that the number of small scale "industrial" gasifiers is growing. They are now available worldwide and there are many reports of good customer service. Gasifiers that were only available in Europe are now being installed in North America.
Wood chip and pellet gasifiers in the 40-125 kWe range are now running 7000 hours or more. Some suppliers: Spanner <http://www.holz-kraft.de/en/> - 600 units Volter <http://volter.fi/> - 100 units Holzenergie <http://www.holzenergie-wegscheid.de/?lang=EN> - 60 units Burkhardt <http://burkhardt-energy.com/hp604/Wood-Gasifier-V-3-90.htm> - 100+ (wood pellets) These units all have tight fuel requirements: pellets (Burkhardt) or dry (13-15% MC), and properly sized fuel for reliable operation. Some suppliers offer sizing and drying equipment. They are all expensive so they require applications where there is high value for the heat and the power. What has been the owner-operator experience of running these systems? Tom
