S1a and M2 Automatic

[nw-mailing-list at nwhs.org]

I'm no mechanical engineer, but lessee, at, lessay, 25 pounds/scoop, that'd be 20 scoops/hour. The next question I'd ask would be how active would the engine be in that hour? Dunno how feasible that 500 lb.'s/hr. is, but it sounds feasible depending on the usage rate/load methinx  IMHO. Still, I've only fired oil burners. My $.02

  Jim,

  Thanks but I don't think this could be accurate.  I am sure you remembered what you heard but this level of coal consumption is under 8% of the maximum firing rate of the engine.  I find this to be a highly unlikely value.   But thanks for giving me what you had.

    The capacities resulted from the designers seeing how big a tender they could put on that frame  and still allow clear vision to the back.. Incidently, the frame on both tenders under consideration was the same one. (from a USRA 12,000 gallon tender) At the time, I think I heard someone in Bluefield say an S1a burned 500 pounds an hour, so the 15 ton bunker would last 48 hours or more at that rate.

    All,

    Some questions/clarification:
    First on the coal side:
    The S1a had a 15 ton tender.  this was designed around 24 hours? or 12?
    The M2 Automatic had 20 ton tender.  I read it was designed around 2 days of fuel 48 hours?  Is this true? 

    Second Water:
    The S1a had 13,000 gallons in tender.  what time span was this based on. 2 fills per coal fill? 3
    The M2 Automatic 11000 gallons.  Any ideas?

    Thanks,

    John Rhodes
