Bowland Bioenergy is an SME manufacturing woodchip biomass and selling it in Lancashire. Based in a Grade 2 listed barn and associated farm infrastructure the old silage store and shippon now form fuel stores which also house the Fliegl batch chip dryer. The use of woodchip as source of fuel is a growing option to mitigate greenhouse emissions. The drying process however remains not sufficiently efficient owing to the emission of volatile organic compounds, dusts and hot air. This project investigates the design options to filter the airflow and harvest energy it contains. These options are anticipated to affect the processing time and performance of the drying process. The quality of dried chips and heat recovery will be assessed both experimentally and by modelling based on the design and operating parameters.The use of woodchip as source of fuel is a growing option to mitigate greenhouse emissions.
