概要

Digestion gas derived from drainage is renewable in nature and thereby does not contribute to the net atmospheric concentration of the green house gas carbon dioxide. Digestion gas composition is 60% methane, 40% carbon dioxide, a small amount of siloxane, hydrogen sulfide in general. Especially, siloxane is harmful compound that is volatile organic silicone compounds derived from shampoo, hair rinse, etc. The conversion of organic silicone components to the abrasive inorganic solid in SiO_2 in combustion would cause damage on liner, turbine impeller, etc. MGT co-generation unit with de-siloxane unit was running under continuous maximum power up to 80kW. Operation pattern was DSS (Daily Start and Stop), or continuous running. Periodic inspections at each 500hrs by approx. 3000hr were conducted. No affect by siloxane were observed at each inspection.
