Heat supply for biogas plants. Part I: Heat recovery from effluent and efficiency of digester heating systems

Die Bodenkultur 37(3): 269-285

Heat supply for biogas plants. Part I: Heat recovery from effluent and efficiency of digester heating systems

Heat and energy requirements are discussed for a biogas plant processing liquid cattle slurry at a fresh slurry temp. of 10 degrees C, ambient temp. 0 degrees C and reactor temp. 30 degrees C to produce 20 msuperscript 3 methane after 20 days. Studies showed that small on-farm biogas plants are only economical when the substrate is pre-heated by heat recovery from the warm effluent. Efficiency and reliability of various heat exchanger designs are compared.
