three-phase generator set / biogas

Biogas can be used as fuel in electrical power generators (gensets), consisting of a standard diesel engine modified for biogas use, and an alternator. Such electrical power generators are on the market in various capacities from small units of less than 100 kW all the way up to 1700 kW.



This becomes all the more interesting as many countries have now introduced legislation which results in a payment by the utility companies of a premium for these green kWs, over and above the normal kW price for power generated by the use of fossile fuels.

In order to secure a trouble-free operation of these gensets, and minimize their maintenance costs (engine oil changes, ), the manufacturers/suppliers have imposed a number of conditions on the quality of the biogas. Prominent among those conditions, apart from a minimum calorific value (CH4 content), are maximum allowable sulphur content and % humidity.
