O-19 資源有効利用率を考慮した地域バイオマスエネルギーシステムの設計

抄録

This study aims to design the regional biomass energy system considering effective utilization rate of resource and fossil fuel reduction rate. First of all, energy density maps in Koriyama city are drawn, and the demand buildings are selected from higher heat density area. As heat demands, the fuel consumption of space heating and hot water are estimated. The district heating network is designed instead of traditional individual heating system, and the total heat pipe length is 1,787 m. Woody biomass are collected from Koriyama city, and average transportation distance is 23 km. As results, the chip boiler has the largest fossil fuel reduction rate 0.85, and the gasification CHP has the smallest CO₂ reduction cost 38,000 JPY/t-CO₂.
