Gas blending technology improves CHPs
New equipment has been developed from ETW Energietechnik GmbH that blends two gas streams of different qualities to fuel CHPs. Precisely blending the two gases to a homogeneous fuel mixture the equipment 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 automated 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 start-ups the CHP receives the perfectly balanced fuel, preventing start-up 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.
