项目摘要

Bioenergy is expected to become one of the energy resources to cope with global warning and exhaustion of fossil fuels. In Europe, the electricity power generation system and the heat supply system by bioenergy resources is very developed.As the plantation area has expanded after World War II in Japan, afforestation has progressed to mountainous regions located in local towns and the plantation area occupies more than one-third of the whole area of Japan. Recently the thinning and treatment for it are needed, but they are not executed enough by the reasons of low utility and low-price of logs. And it is added ; in the local towns the pollution of the water quality by the livestock-wastes bccome to be serious problem. The continuance of the local towns become strictly important and necessary with requirement of new solution fiom the viewpoint of global warning, exhaustion of fossil fuels and water environment preservation.The objective of this project is to seek the applicability of bio … More energy by wood residues (included the thinned logs) and the livestock wastes realizing the CO2 circulation and water environment preservation into Japanese local towns.In the study periods, several study trips were conducted in Japan and foreign countries, that is Sweden, Germany, Switzerland, Astoria and New Zealand, and Okayama, Miyazaki, Iwate prefecture and Hokkaido. The focuses of the study trips in the foreign countries were followings ; wood production and treatment activities, collecting and using methods of wood and wood residues as bioenergy resources, collecting cost of fuel and its price for fuel and the Biomass energy system in the town. From these we recognized the whole wood biomass utilization system from forest to end-user.The experimental and theoretical studies on combustion characteristics in a free board of an internal fluidized-bed fumace for development of steam-driven power generating system-using livestock-wastes as fuel were conducted. And the co-firing with wood waste and livestock waste was analyzed. The results show that the fuel gases are completely burned in the furnace, maintaining the furnace at high temperatures.In Japan, the test analyses for wood waste and Livestock wastes utilization were conducted in Hita city, Ohita Pref., Miyazaki Pref. and Ashoro town in Hokkaido. In all cases the Biomass energy resources are existed enough to create the new energy supply system by biomass and its applicability's were recognized to be high sufficiently.We held the seminars in Hita city, Oita pref. (July 2000) and Ashoro town, Hokkaido (January 2002) for the citizens. Totally more than four hundreds citizens participated in these seminars. And the research reports are published in December 2000 and March 2002. Less

生物能源有望成为科普全球变暖和化石燃料枯竭的能源之一。在欧洲，利用生物能源的发电系统和供热系统非常发达。在日本，由于第二次世界大战后种植园面积扩大，植树造林已发展到位于当地城镇的山区，种植园面积占日本全国面积的三分之一以上。近年来，人们对木材进行间伐和处理是很有必要的，但由于木材利用率低、价格低等原因，间伐和处理还没有得到很好的实施。在当地城镇，畜禽粪便对水质的污染已成为严重问题。从全球变暖、化石燃料枯竭和水环境保护的角度来看，当地城镇的持续发展变得非常重要和必要，并需要新的解决方案。本项目的目标是寻求生物技术的适用性。 ...更多信息在研究期间，在日本和国外，即瑞典、德国、瑞士、阿斯托里亚和新西兰，以及冈山、宫崎、岩手县和北海道进行了多次考察。国外考察的重点是：木材生产和处理活动，木材和木材剩余物作为生物质能源资源的收集和使用方法，收集燃料成本和燃料价格以及城镇生物质能源系统。本文对以畜禽废弃物为燃料的蒸汽动力发电系统的开发中所采用的内循环流化床锅炉的燃烧特性进行了实验和理论研究。并对木质废弃物和畜禽废弃物的混烧进行了分析。结果表明，燃气在炉内完全燃烧，使炉内保持高温。在日本，在大分县日田市进行了木材废弃物和牲畜废弃物利用的试验分析，宫崎县和北海道的阿肖罗镇。在所有情况下，生物质能源的存在足以创建新的能源供应系统的生物质和它的适用性被认为是足够高的。我们举行了研讨会在日田市，大分县（2000年7月）和旭路镇，北海道（2002年1月）为市民。共有400多名市民参加了这些研讨会。研究报告分别于2000年12月和2002年3月发表。少
