1.引言地球上存在着大量的木质资源,它们易收集,是一种较易利用的能源。木质燃料着火性好、灰分少,含S、N较低,燃烧时排放的烟尘,SO_2和NO_X较少。利用废木材时价格便宜,具有较好的经济性。木质燃料的缺点是含水量高、单位发热量低,因此不能用在要求高温和能耗量大的场合。木质燃料的来源还有季节性变化,必须设法保持稳定供应,如长期存放需要采取防腐措施。本文介绍大分县山村产业公司使用木材锅炉的情况及其节能效果。
1. INTRODUCTION There is a large amount of wood resources on the earth. They are easy to collect and are a relatively easy-to-use energy source. Woody fuel has good ignitability, low ash content, low S, N content, and smoke and soot emissions during combustion, with less SO_2 and NO_X. The use of waste wood cheap, with good economy. The disadvantage of woodfuel is the high water content, low unit heat, it can not be used in demanding high temperature and energy consumption of large occasions. There are also seasonal variations in the sources of woody fuels and efforts must be made to maintain a steady supply and anticorrosive measures should be taken for long-term storage. This article describes the case of using a wood boiler in Oita Mountain Village and its energy-saving effect.
