I saw an EvoWorld wood chip boiler at the Albany, NY home show tonight. I couldn't really get it straight. It seems a couple of US guys partnered with EvoWorld, which used to be EvoTherm from Austria, and they are making certain mechanical and pressure vessels at the Troy (NY) Boiler Works (ASME) stamp. I'm really unclear on the whole arrangement, but they had a wood chip boiler there that had lambda control, variable speed forced and induction fans, variable feed rate, self-cleaning (the turbulator tubes are autumatically moved up and down periodically). They said the pellet boiler is (will be) similar. They got some NYSERDA funding. Not sure about the Austrian tie-in or anything, but it sure looked like a nice unit. They recommend a buffer tank.
Here is the EvoWorld partners site:

It looks like EvoTherm was bought out since the website now forwards to Greentech:
