Title: WMO burners: How many KWH per gallon?
Post by: Number21 on October 18, 2009, 11:38:10 AM

I'm just curious those of you that have burned WMO in your generators, approximately how many KWH are you generating from a gallon of fuel?

right at 10kwatt hours burning a mix of 50/50 (15/40 and pump diesel)
in a S195 idi changfa

and i think it is possible to get to 11kwatt hours per gallon under specific conditions
in a very well setup unit optimized to to burn wmo in higher ratio's of oil

Bob,
Are you saying 11KWHrs/gal of the mix or per gallon of  WMO?

I run primarily WVO, but I have run about 10 gallons of WMO in a test recently and it produces close to the same output as WVO.  In my metro 6/1, I get about 3 hours run time putting out 3-3.5 KW.  The test was run on 100% WMO.  I don't know how happy the engine will be long term running straight WMO, but it seemed to run smoothly without any apparent ugly noises.

May I add, that the test was done with startup and shutdown on diesel, I used a cheap 12v auto fuel pump to get fuel from the tank (mounted below injection pump level) to the IP, and used a fattywagon type line heater.  Normally the line heaters supplied are around 30" and you use about 6" per line on a 5cyl mercedes.  I used the whole length wrapped spiral around my 6/1 injection line.  That has GOT to add a bunch of heat in the long line of slow moving fuel.  I figured that as long as the IP can handle the thicker fuel, atomization should be reasonable with the warm engine, and a really hot injection line.

Or I could be an idiot destroying my engine........ time will tell :)

It's the same as diesel or veg oil but I don't see it makes much difference as it's free any way.
For there to be much difference between diesel and wmo, the engine wouldn't be running right and possibly being damage.
