Mixture of Natural Gas, Air, and Biogas Interchangeable to Town Gas

CAM supplied a variable capacity venturi mixing unit (2 variable venturi mixers) that uses Natural Gas as motive gas. A specific flow of Air and Biogas is aspirated by the mixers. The final result is a mixture with the same Wobbe Index of Town Gas. An air blower is necessary to create the correct blend of Air and Biogas, since Biogas is available at a pressure of 150-200 mbar.
