Efek Penekanan Dan Pemanasan Pada Proses Pembriketan Biomassa Hasil Torefaksi Terhadap Kualitas Briket

Torefaction is one method of utilizing biomass waste into fuel through a thermal process that takes place at atmospheric pressure with a temperature range of 200-350 ℃ to a solid quality fuel equivalent to sub-bituminous coal. Densification aims to increase biomass mass density. The combination of densification and torrefaction is an attractive process option to get high quality briquette and pellet fuel. Making briquettes with the hot printing method is able to eliminate the adhesive material so that the process of making briquettes is faster, direct briquettes can be used without a drying process and are able to maintain the calorific value of raw materials. The purpose of this study is to examine the effect of suppression and heating on the briquetting process of torefaction results on the quality of briquettes based on the physical properties of the drop test, water resistance, combustion temperature and length of combustion. The best quality briquettes found were 8 tons of briquettes with a temperature of 150 ℃, where the briquette drop test did not lose much material. In water resistance testing, the water absorbed in 8 ton briquettes with temperature of 150 ℃ is quite low, and when testing the combustion of briquettes is also quite good.
