Kawasaki Delivers First Woody Biomass Gasification Cogeneration System
Aug. 22, 2006
Tokyo, August 22, 2006 — Kawasaki Heavy Industries, Ltd. announced today that it has delivered its first gasification cogeneration system using woody biomass to the Azai factory of Sekisui House, Ltd. in Shiga Prefecture.
Kawasaki’s system, utilizing its advanced gasification technology, generates electricity by processing the wood waste from timber production to supply power to the Azai factory itself. It will be used in a bioenergy demonstration project being jointly conducted by Sekisui House and the New Energy and Industrial Technology Development Organization (NEDO).
The system’s gas engine generates electricity from refined CO and H2 gases that are produced when Kawasaki’s low-tar pyrolysis gasification furnace processes solid wood waste. The exhaust heat from the engine will be recovered by a heat exchanger and used for the Sekisui facility’s wood driers, as well as for office utilities. The cogeneration system will supply 1,750 kWh a day (10 hours) from 2.2 tons of wood waste, equivalent to 30 percent of the factory’s electric power demand.
