CLASSIFICATION OF BINDERS IN BRIQUETTE PRODUCTION TECHNOLOGY

Abstract

The production of biomass briquettes often entails the collection, transportation, storage, processing, and compaction of loose biomass that meet specific quality parameters. The densification process often involves the addition of binders to improve the cohesive strength of the briquette material. Briquetting is the process of densification of biomass to produce homogeneous, uniformly sized solid pieces of high bulk density which can be conveniently used as a fuel. In this process, the raw material is pressed together at an elevated temperature and forced through an orifice. In a pure briquetting process, the pressure and temperature make the material bond with the help of its own lignin which acts as a binder. In some process utilizing a lower pressure or a lignin poor raw material, a separate binding material may be added.
