    Dual Fuel Generation

    Thanks all for your input. I've come back to ABC in Belgium do a 2500MW dual fuel engine Wartsila smallest engine is 5.8MW so was way too big for us. Will try Hyundai (thanks TugboatEng). Have a good weekend. Signing out......

    Thanks all I have approached CAT. they only produce an engine that takes a 70% gas and 30% diesel blend so a non-starter or derates by 50% on gas only. Regards fuel gas compostion we will install a fuel gas conditioning skid to drop out any liquids etc and ensure compatibility with whatever...

Our engines need to run on both natural gas and diesel. The natural gas has a predominantly methane base and comes from cleaning up associated gas that...

The obvious choice is gas engine but I need to also be able to operate on diesel in the event that the fuel gas system fails. So I'm in the market for 4 x 2.5MW; 400V; 50Hz gas/diesel reciprocating machines. To date...

    ESP/VFD Issues

    I have a number of ESP drive trains that are powered from island generation at 400V;50Hz through a 450kVA VFD and a 525kVA step-up transformer to 2600V then down hole cables of varying lengths from 1000m to 2600m to a 225kW pump motor. The VFD has an output filter. The VFD operates as a 6 pulse...

    Thyristor Controlled Heater vs Diesel Genset

    I have a 226kW heater that's controlled through a 12 pulse thyristor unit. This has caused system instability on our small network causing the main power generator (Gas Cat with Woodward Electronic Governor) to hunt. Changed the control card in the thyristor unit to proportional control...
