Studies on biomass densification and Corrosion thermal conductivity and Coating analysis of piston type Briquetting machine die

Abstract

This study is undertaken to examine the development and characterization of sawdust briquette as well as the enhancement of the life of the briquetting machine die with high quality of briquettes. The global environment is polluted from biomass waste which is being derived from agriculture and woodworking industries. Generally, high quality briquette is produced from sawdust of saw mills. Hence, the vast production of briquette has resulted in high demand for sawdust as southern India is experiencing very high cost in this respect. Due to this high demand and cost of briquette, a lot of agriculture bio-waste was used for reduction in sawdust utilization. As this biomass waste mixture along with sawdust is utilized for making briquette, their selection, collection, drying up, and proper sizing are very much significant in the pre-treatment processes for turning the mixture into briquette. However, in briquette making processes, volatile matter, ash content, moisture content, carbon and heating value shall be considered as testing parameter. On the basis of test report, it can be stated that in the briquette making process cashew nut shell, neem leaf and sawdust are considered as the best bio-waste mixture. Further, the cost of briquette making could be reduced by using the apt mixture of bio- wastes. Piston press, screw press, palletting press are some of the common methods for manufacturing briquettes. The density of the sawdust is increased by applying high pressure which leads to the generation of high temperature. The quality of the briquette is an influence of the density. Concentrating on certain factors such as heating value, burning speed, etc. can increase the performance of briquette. Durability of the briquette is increased based on the increase in moisture content newline
