Waukesha Gas Engine FG Specifications

Waukesha Gas Engine FG Specifications

(OP)
Hi All
Can anyone share waukesha gas engine fuel gas specifications, in my company we don't have it as installtion of these gas engines are very old.
Regards

RE: Waukesha Gas Engine FG Specifications

Here is a copy of fuel spec for most natural gas engines that Waukesha built. However, Waukesha built a lot of engines for use on fuels other than "standard", such as biofuels, coal seam gas, mine methane and syn gas. Since you didn't provide much other info this is about the best answer you can get right now.

If you need further info your best bet will likely be your local Waukesha dealer.

Hope that helps, MikeL

Hi Catserveng,
These gas engines are back installed in 1960s by ESSO in Libya for compression facilities,over the time passing gas composition has been changed. our maintenance team facing frequent maintenance related issues. In Libya no local sales office is available.
Hope you have good idea to understand my question.

RE: Waukesha Gas Engine FG Specifications

So actually a fairly common problem with older sites.

How were your engines originally setup? Was the fuel treated to "pipeline" quality? Or were the engines setup to run on wellhead fuel?

When you say composition has changed, in what way? Has BTU value gone down or up?

What kinds of maintenance problems are you having? Rough running, poor performance or stability problems? Or engine failures, like burnt valves?

How are the engines being tuned? For older engines you could get away with a vacuum gauge (on natural aspirated engines, pressure gauge on turbocharged engines) and adjusting the power valve until you got best performance. If you had a large change in fuel composition, the carburator components like the fuel valve, diaphragm spring and orifice may no longer be correctly sized. A really big change in fuel quality may also require modification to the fuel pressure regulator, usually just pressure setting and maybe a spring change, but sometimes an orifice change as well.

Clarke Energy has an office in Tunisia, and they have service engineers and technicians with Waukesha expertise, so they may be able to provide some assistance in your area,

Hope that helps, MikeL.

Fuel gas is not pipeline quality, it is from separator. mw weight is 23~25 and water contents about 150 lb/mmscf.
I'm process engineer and I don't for setting of fuel gas system. My manager told to me to get waukessha gas engine fuel gas specification for fuel gas conditioning system. I hope may be my company will install some fuel gas conditioning system now.
Regards

RE: Waukesha Gas Engine FG Specifications

Gas engines dont require hydrocarbon dewpoint conditioning, so that makes the configuration of the fuel gas system simpler. However, supply piping to the gas engine should slope back continuously to the fuel gas scrubber, else a local KOD at the gas engine will be required. Believe natural gas in Libya is high H2S, so check Waukesha gas engine fuel gas specs for max permissible H2S concentration limits.

RE: Waukesha Gas Engine FG Specifications

Hi george,
Thanks for your valuable input, H2S in gas is .5% while waukesha fuel gas specification is max 0.1%. I discussed with waukesha service engineer in pakistan and they told me same as you suggested.
Best Regards
