Remarks We installed the high performance boilers "Multifire" made in Austria where advanced in biomass technology.
There are only 4 units of "Multifire" in Japan. Ours are the 3rd and 4th units in Japan.
Those boilers could make the electricity, the frequency of ash handling pretty smaller.
We could reduce the construction cost for wood chip silo by using available high ground (height 1.6m) in parking lot.
