Abstract

<p>Based on the FIT（Feed in Tarif）act enforced in July 2012, Chuetsu Pulp & Paper Co., Ltd. Sendai mill started a power generation business using 100% wood fuel as of thinning wood and general wood from November 2015. It was realized by taking advantage of the rich forest resources in south Kyushu and our traditional efficient wood harvesting system. The problems such as facility rising troubles and output reduction phenomenon were solved, total operation has been stabilized finally. After that we tried to reduce equipment’s own power consuming ratio to maximize the external power sales volume. As a result of taking actions ⑴ installing appropriate inverter system, ⑵ replacement of fan and pump to the efficient type, ⑶ setting improvement of each system, the own power consuming ratio reduced from 10.7% to 10.1% and we achieved sales increase. In this paper we introduce the power saving method in the wood biomass generating facility’s operation, implementation cases for each equipment and finally the result of electric power saving.</p>
