I've beleived you all along Ian! I'm not so sure that it completely makes up the 30% but it must be contributory. The steam expansion, though greater in volume than the fuel is much slower but at only 90RPM or so It must be a factor IMO
DEAR PREP H re your last comment . Is that not what I have been saying all along. The water content of MSAR in the combustion chamber has to turn into steam . and I am convinced that the steam pressure will provide equally as much power as the 30% fuel oil it replaces . SO THERE !!!!!!!!!!!!!!!!!!
1400, cant see the full list of trades now as don't have level 2, was referring to 2 or 3 circa 100k (volume) trades just prior to my post... all at top of the spread... not huge money... but an indication small pi's still buying. that's all.... wasn't ramping, just an observation
Some interesting stuff. Particularly read the last few paragraphs though...
"My own test's and, as one can see from the patents cited above, much prior art has shown that these fuels produce as much power in a conventional internal combustion engine as stright hydrocarbon fuel alone. Dr. Gunnerman addressed the dilemma by theorizing that additional btu's where being obtained through the catalytic dissociation of hydrogen and oxygen from water. After deciding that this may be a situation where Occam's razor is beneficial.My theory is that what was once wasted heat, everyone knows who has touched a hot exhaust pipe that an internal combustion engine produces copious amounts of, causes the water once in the combustion chamber with the burning fuel to flash into steam and drive the piston along with the other expanding gases. This theory easily explains the increased mileage from the less btu's of fuel. The efficiency of the engine is increased by utilizing the traditionally wasted heat to expand steam."
So does a barrell of MSAR create as much thrust power as a barrell of HFO? I think there's something in this and that with MSAR, Maersk will be partly and beneficially reverting to the age of steam!
Interesting article in the Sunday times yesterday.. http://www.thesundaytimes.co.uk/sto/news/uk_news/National/article1396924.ece 'Diesel Deadlier than Petrol' ..government have 'realised' the dangers of particulates from diesel emissions from older cars which is of course a chance to take revenue. Any less than euro6 vehicle will pay a hefty charge to enter London and other cities from 2020.
It certainly brings the issue of particulates to the fore and on this front, a ship using MSAR could drive down the A13 without concern! ;-)
Ah Nimrod..... Now there's a real engine from the past, opposed piston type with all those cooling hoses. Sadly I never actually sailed with one and always regret not having done so
PrepH I guess your very much on the right track about the pre- heating, unfortunately like much of the Marine MSAR specs and advantages we still have these to be revealed and I guess in the fullness of time all with be will be forthcoming. It will be certainly interesting for those in the field so to speak.
