Abstract the densification process is broadly categorized into two different types: hot and high-pressure densification and cold and low-pressure densification. under these two broad classes different aspects of densification, such as machinery for densification, mechanism of densification, factors affecting densification, raw material preparation, binders, and the like, have been discussed.
Abstract. all kinds of biomasses pull carbon out of the air as they grow. waste biomass can be made into usable fuel by densification. these biomasses can then replace some coal in power plants, which will reduce carbon emissions and greenhouse gas effects. densification of low-density biomass (agricultural and agro-industrial waste) is called biomass.
Additionally transportation costs are minimized with the higher density of coal. to utilize biomass effectively in combustion processes developments are needed to allow biomass to be processed and handled more similarly to coal. densification of biomass into small pellets or briquettes is believed to be a good first.
Attempts to overcome the poor handling properties of biomass, i.e. its low bulk density and inhomogeneous structure, have resulted in an increasing interest in biomass densification technologies, such as pelletization and briquetting. the global pellet market has developed quickly, and strong growth is expected for the coming.
