Design of a Biomass Burner/Gas-to-gas Heat Exchanger for Thermal Backup of a Solar Dryer

The solar drying process is interrupted during the cloudy or rainy days and also at night. Thus, a combination of mixed mode dryer using solar as main input and biomass burner as auxiliary source of thermal energy will compensate for the absence of the solar radiation. This study describes a detaile...
