3-2-2 A Cascade Biomass CHP for Bamboo Utilization

Abstract

A Biomass CHP system was completed by Bamboo Energy Co., Ltd. in Nankan Town, Kumamoto Prefecture, in March 2019, as the first full-scale Organic Rankine Cycle in Japan using bamboo for biomass. It has a capacity of about 1 MW electricity, 2.8 MW thermal oil supply, and 4 MW warm water supply, with total energy efficiency of about 70%. The well-known difficulty of burning bamboo has been successfully solved by burning it with bark based on fundamental research for a long time. In this report the development from pilot tests to full scale plant is outlined.
