Hi Tom and list,
The Bionear gasifier is very interesting, but it is difficult to get a grip on it. The man in the video is the inventor himself, Timo Heimonen. I have met him several times and also seen several of his systems in operation during the last few years. The gasifier in the video is located in Lestijärvi, Finland where it primarily serves a district heating system. The turbine has earlier served as a diesel powered emergency power station at bank of Finland and has been modified for use on producer gas. On the same site in Lestijärvi where Turos teams unit now is operating, another gasification plant was in operation for a few years. This previous gasifier had earlier been located in Tervola in Finnish Lapland and then modified for service in Lestijärvi. The operation in Tervola was unsuccessful. In Lestijärvi the plant was in operation, but there were problems with gas quality. The rapeseed oil press and the drying facility, were already on the site when Turos Team came into picture. The gasifier in the video is the first of Turos teams units that is running as a real installation, not “at home” for them. I visited the plant in Lestijärvi two days ago. At that time the turbine was not in operation due to too little heat load at the time (+4 C). The district heating system was in operation and run on producer gas. The unit is over dimensioned for the site and a portion of the produced gas also was flared. Based on the color of the flare, the gas seemed to be of real good quality. Not entirely soot free, but with a flame looking like when clean tar free wood gas burns in a flare. Previously I have had the opportunity to see flares and also smell dripping condensate from another of Turos teams smaller units. The concensate was like spring water. For heat sold to customers in a district heating system in Finland, one can typically take a price of about 70-80 €/MWh. For electric power delivered to the grid, one gets the Nordpool FI price minus a margin. This price varies, but it usually is within the range of 30-50 €/MWh. At the moment it is about 35 €. This means that it mostly is clearly more interesting to produce heat than power. In the entire building in Lestijärvi, there was no smell of tar or smoke, and the process seemed to run very smoothly. Time by time one could hear small amounts of wood chips being fed to the gasifier. As is mentioned in the video, there is no access to the interiors of the gasifier except the two 2” plugs on the side. In the gas piping there is a small trap for flyash, but it this is not really designed for removing much anything. The gasifier was fed with wood chips with a humidity of about 30 % and according to the inventor additional water was added at a rate of 10 l/h. The statements of how much fuel was measured to be consumed per produced MWh were not believable, 200 litres of wood chips/MWh. This is about one fourth to one fifth of the amount that should be needed. Mr. Heimonen was very aware of this himself too. I have been dealing with gasification for many years and seen and heard unbelievable statements before too. When something is too good for being true, it tends to show up that it also is not. Water did not burn in Reisijärvi either despite earlier statements made by another company… This unit in Lestijärvi is the most impossible unit I have seen so far, but it seems to work. I can not believe the efficiency statements and the presented values, but I can see that the unit produces a clean gas and that the process seems to run very smoothly. Measurements made by VTT (Technical research centre of Finland) on one of the earlier units also showed impossible values. The construction of the gasifier is a well kept secret. No patents or other documents on this are available. I keep my thumbs for Turos team and Mr. Heimonen! Gasification suffers from too many failures, success stories are needed! The laws of nature are hard to break, but also if the values are not true, a well functioning system is worth a lot.
