In this thesis, the common agricultural and forestry wastes Jiangsu poplar sawdust as raw material, which carbonized charcoal obtained by Young , adding the right amount of adhesives and igniting agent prepared fast burning charcoal. Of the final carbonization temperature , holding time, the type of adhesive , Yang charcoal moisture content, particle size , igniting agent and its added amount , plastic carbon ratio, the molding pressure , forming time and the forming method and other factors added loess for fast burning charcoal performance. Forming flammable adhesive developed toner powder fuel can be used for other molding . Process for preparing fast burning charcoal as follows: the water content of about 15%, particle size lt; 0.250mm Yang charcoal and 5% of its ignition agent C were mixed and then with combustible corn starch adhesive prepared to 0.6:1 carbon ratio of the plastic uniformly mixed in a molding pressure of 25MPa under pressure for 2min, 5s can be obtained rapidly ignited , the combustion smoke , odorless, quick burning charcoal. The fast burning charcoal burning moderate speed , uniformity is better not touch , will not spread , combustion residue content of 11.96% , the burning time last 9.00min · g-1, compression factor of 6.29N · mm- 2. 30g charcoal burning speed of the heat released over longer periods of time so that the water temperature maintained at a certain temperature range. Combined TGA , elemental analysis and the actual combustion of charcoal burning speed the performance of system. Obtained using the differential method of fast burning charcoal fire point , and through data analysis of the TG curve fast burning charcoal burning process.
