Cool Producing Systems Based on Burning and Gasification of Biomass

This paper introduces utilizing of biomass for production of cool. Two different thermal systems are considered as sources of a driving thermal energy, namely burning and gasification of biomass. Burning of biomass produces a hot water or steam used as a driving heat source for an absorption cycle. The mixture of water and LiBr is considered as an appropriate working medium in absorption systems. Different parameters of the absorption system were tested and compared. Gasification in an atmospheric fluidized bed reactor connected with a trigeneration unit is considered as another thermal system utilizing primary energy of biomass. The system enables to use together an absorption cooling cycle and a vapor-compressor cooling cycle. Efficiency of both systems are calculated and compared. Parameters of the gasification process were derived from measurements carried out on the experimental gasifier at the Brno University of Technology.
