Agricultural Anaerobic Digesters: Design and Operation

The biogas fuel supply to the boiler was adjusted according to digester-heating needs by regulating gas pressure at the burner with a throttling valve. The pressure was manually adjusted between 0.8 and 5 in (20 and 125 mm) water gage which corresponded to 35 to 95 ft 3 /hr (1 to 2.7 m 3 /hr) of biogas depending on outside temperatures and ...
