    Short of the fact that the machines already exist, there is little to recommend burning oil in a steam engine, rather than in a diesel. If the fuel is suitable for diesel combustion, then the efficiency difference will be immediately apparent.

    There is rather less need for a fireman in the crew, though, as fuel transfer can be more easily automated.

    IÉ oil-burners were identified by large white discs on the smoke-box door and the sides of the tenders.

    Coal is a more economic option. Apart from the practical issues mentioned above, the cost of conversion, maintenance if the apparatus, greater maintenance requirements and so on, the running costs of a diesel would be less.

    Hi

    Check out L.D.Porta, he transformed the ould steam engine into a high efficiency, multi fuel burning system in Argentina back in the late 40's. His efforts were stunning but very little accepted by British loco engineers- they never even heard of him. Some of his small locos still run today....

    Flash steam boilers are the one, though its not the same as shovelling coal or burning black oil, but very efficient, generating more steam than required to run a loco. These systems are very small would fit in any loco boiler and made of modern stuff. Currently used in modern heating systems for large buildings. They are also portable.

    On the preservation side of things Alan J Haigh loc engineer and others have designed high efficiency furnace & boiler systems for some of the preserved locos in the UK, one loco they did in North Wales runs it's trip on one bucket of coal where before its modern restoration it required several for the same trip.

    Thanks, that's very interesting stuff guys. One question, did operators using oil not put in place procedures to raise boiler temps more gradually when using oil to bring locos up to operating temperatures, and therefore avoid the problems highlighted above?

    Only reason I posed question about oil/kero was as an option for preserved steam locos in light of perceived high coal costs.

    That's a case of 'Now' and 'Then'

    If a new build was to be designed anything is possible, all dependant on the group doing it- lets go authentic! or lets go modern and efficient!

    The Festiniog used a by product of refining for bitumen known in the trade as LMD. Its a high sulphur product that can only be used for external combustion, eg. boilers, on land but works very well in ship engines of most types. The sulphur is not a problem once off shore!
