ETW Energietechnik developed a new gas blending technology for CHPs
Innovative solution that improves the feasibility of land-fill gas and other CHPs.
Moers, 8th August 2016: ETW Energietechnik GmbH developed a new equipment that
blends two gas streams of different qualities to fuel CHPs. This equipment precisely
blends the two gases to a homogeneous fuel mixture and is indicated for landfills that
struggle with shrinking heating values and volumes of biogas along their lifetime. This
shrinking heating value can be compensated by gradually enriching biogas with natural
gas (NG). The blending is completely automatized and designed to consume the
lowest possible amounts of NG. Almost any CHP can easily be upgraded.
There are several advantages for the operator. At startups the CHP receives the perfectly
balanced fuel, preventing startup problems caused by low CH4 concentration.
That enables the operation of CHPs even with CH4 concentration lower than 30%,
increasing its lifetime and availability, thus its economic feasibility. The CHP can be
operated independently from the land-fill gas supply.
