摘要

The purpose of this study was the development of briquetting technology for biomass fuel by using three agro-forestry wastes (cultivation bag waste (CBW), flaxboard (FB), and rice straw (RS)) as raw materials. After solidification processing, the manufacture of solid biomass fuel briquette, as well as the analysis of related properties, and then carries on charcoalization processing to make the solid fuel charcoal briquette. The efficiency of solid biomass fuel charcoal briquettes; (ESBFCBHV (%)) after charcoalization for solid biomass fuel briquette were analyzed. The volatile combustible matter of three raw materials were between 74% and 79%. Carbon and hydrogen chemical element content were 61~66%. The volume spring-back of specimens showed steady state after fifth day during experimental duration. The largest volume spring-back of CBW and RS specimen were in the thickness direction, and the FB showed in the width direction. The hardness and compressive strength showed the RS ＞ FB ＞ CBW. and the FB ＞ CBW ＞ RS (0.05 level ),respectively. The charcoal yield of specimens significantly decreased with increasing the charcoalization temperature and retention time. Low- temperature (300℃) is higher than the high-temperature (900 ℃). Also the ash and the pH value increased with increasing the charcoalization temperature. The tendency of the volume shrinkage and the density loss percentage increased with increasing the charcoalization temperature and retention time, especially the high-temperature charcoalization. Charcoalization processing can promote the heating value of the specimens, and increase with increasing the charcoalization temperature. There are showed linear regression significantly positive correlation. In the same charcoalization temperature, the heating value also increased with increasing the retention time. After charcoalization, the efficiency of solid biomass fuel charcoal briquettes (ESBFCBHV (%)) for three biomass fuel char briquettes showed the CBW 25.1~112.6%, the FB 48.2~105.6% and the RS 25.0~145.3%, respectively. And also the tendency of charcoalization temperature of the order is 900℃＞700℃＞500℃＞300℃.
