Abstract (en)
[origin: WO2008025158A1] A check valve installed in an exhaust stack prevents the ingress of atmospheric air which would otherwise be mixed with fugitive gases supplied as a fuel source to an engine. An accumulator is positioned within the ducting which conveys the fugitive gases to the engine from the source of fugitive gases thereby to prevent excessive flow fluctuations of fugitive gas to the engine. Measurement and control of the fugitive gases and engine operation is enhanced.
