Water Injection and cooled exhaust gas recirculation (EGR) could be seen as competitive technologies: it has been demonstrated that at medium load a 40-50 % Water-to-Fuel Ratio (WFR) with Port Water Injection (PWI) has the same effect as an EGR-rate of 10%, which is seen as relatively limited even for petrol engines.

The LMS100 PA gas turbines utilize water injection for NOx control. The LMS100 PB gas turbine uses dry low NOx (DLE) combustors. The LMS100 PB gas turbine uses dry low NOx (DLE) combustors. The first LMS100 PB unit entered commercial operation in 2013.
From the degassing drum water passed to the injection filters. [3] Water was filtered in the water injection filters, one duty and one on standby/backwash. From the filters water was routed to the water injection pumps. The three water injection pumps each had a capacity of 221 m 3 /hr with a differential head of 2068.5 metres (209 bar). The ...
A heated sidewalk in Holland, Michigan Installation of a geothermal snowmelt system on a street in Reykjavík, Iceland.. A snowmelt system prevents the build-up of snow and ice on cycleways, walkways, patios and roadways, or more economically, only a portion of the area such as a pair of 2-foot (0.61 m)-wide tire tracks on a driveway or a 3-foot (0.91 m) center portion of a sidewalk, etc.
Gas turbines with DLE technology were developed to achieve lower emissions without using water or steam to reduce combustion temperature (Wet Low Emission (WLE) technology). [ 1 ] [ 2 ] WLE technology demands cleaning of large amounts of water, is heavy, takes more space and can be difficult to install offshore. [ 1 ]

These gas engines are usually medium-speed engines Bergen Engines Fuel energy arises at the output shaft, the remainder appears as waste heat. [8] Large engines are more efficient than small engines. Gas engines running on biogas typically have a slightly lower efficiency (~1-2%) and syngas reduces the efficiency further still. GE Jenbacher's ...
