CHP a success second time round
June 1st 2007

One of the great claims of micro turbine is its ability to harness the power of biogas.

Just one year after installation at Welsh Water's Wastewater Treatment Works in Chester, operated by United Utilities Operational Services (UUOS), the NewEnCo Turbec is demonstrating it can cope with variations in methane gas quality and quantity and provide an efficient solution which protects the environment and produces low cost renewable energy.

NewEnCo has been developing and proving the Turbec T100 on biogas since 2002 and now has over 25,000 operational hours on its lead biogas installations.The Turbec T100 microturbine has a single moving part and, as the lubrication oil is isolated from the combustion process, the technology is very tolerant of both H2S and siloxanes, unlike traditional reciprocating gas engines - overcoming the reliability issues Welsh Water had had when it tried CHP units in the past.

Welsh Water reports that the plant has operated very successfully since the installation of the units, with average availability figures exceeding 95 per cent.The siloxane and H2S components of the gas have had no adverse impact upon the operation of the CHP units.
