Thanks Fredrik,

Gasification list, Turos Team HKG Bionear and Bioneer have nothing to do with each other as far as I know. HKG Bionear does not produce tarry updraft gas that is cracked with the help of an external reformer like did Bioneer. The mentioned gas composition H2 ~25 %, CO ~45 % is not achievable when using only air as oxidant. Water and air is used, but from where is the needed energy taken? The dripping clear and smell free condensate I mentioned earlier came from a temporary experiment installation, an installation like that that can be seen on other youtube clips on internet with an insulated gasifier and a gas burner burning in open air. On that video the gas line contains many components. One of these is a small MHD generator for testing, not as such essential for the process. http://www.youtube.com/watch?v=hfIgxzd1rHA In the video a catalyst is stated to be used and heavy hydrocarbons to be recirculated into the process. With lower moisture content in the wood fuel than 50 - 60 %, water is added to the process. Turos Team (Bionear)state that they remove not more than a couple of litres of ash and soot per week from one trap, and no condensate at all. The rest of the ash is stated to be gasified and leave the gasifier in gaseous form. When unfiltered gas burns at the flare in Lestijärvi, no sparks or flyash can be seen in the flare, but otherwise the flare looks pretty much like I´m used to see clean unfiltered and not cooled producer gas burn in open air. Clean filtered gas burns, as we all know, with a pure blue flame invisible in daylight. Filtered and cooled blue burning gas burns very well, I asked a friend of mine to extinguish burning gas being blown from my wood gas trailer a few days ago. Despite trials to press the end of the gas hose towards ice and snow on ground, he could not get the flame go out, nor could I. It might seem odd that heat can be more valuable than electric power for an owner of a power plant, but this is the case for power delivered to the grid here in Finland. In Finland roughly 1/3 of an end customers power price is the electricity itself, 1/3 is transfer costs and the last third taxes. Fredrik Ek
