J420 Landfill site Bootham Lane; Doncaster, UK

Fuel Engine type Electrical output Thermal output Commissioning

Landfill gas 2 x J420 2,666 kW - 05/2001 (a), 12/2002 (b)

a) 1st engine b) 2nd engine

At this site, the methane content of the landfill gas can drop as low as 35 %. The fluctuations in the methane content can be handled easily by the Jenbacher engines due to the patented LEANOX* lean mixture combustion system. Thus these variations do not cause any reduction in the high output level of our power systems. The installation is operated by United Utilities Green Energy Limited.

At this greenhouse facility, the Jenbacher cogeneration system provides power for artificial lighting, heating and CO2 to increase the chrysanthemum production capabilities. The CO2 produced from the engine’s exhaust gas is used for the fertilization of the greenhouses, whereas the operator gains additional economic benefit due to the supply of the generated electricity to the local grid.

J420 Containerized solution Biogas plant SBR; Kogel, Germany

Fuel Engine type Electrical output Thermal output Steam production Commissioning

Biogas 1 x J420 1,413 kW 751 kW 1,037 kg/h at 3 baror 698 kW output

10/2003

This biogas plant utilizes leftover food from hospitals, hotels and canteens as well as organic residual waste from the food industry for producing biogas that fuels our gas engine. The electricity generated is entirely fed into the public grid, and the exhaust gas from the engine is used for steam production. The steam serves for the pasteurization of the waste, which can then be used as sterilized fertilizer.
