Re: oil burners

I am assuming you want a pressurized fuel tank for a vaporizing burner (air pressure over the oil forces oil to the vaporizer), similar to a Stanley Steam Automobile setup. Two options: 1. a portable compressed air tank sold at automobile supply houses to fill tires without use of a pump, Harbor Fre...

Re: Miles per Gallon (Litre etc.)

From the 1907 Paper: “ The engine is a two cylinder vertical cross compound, fitted with plain slide valves moved by Stephenson link motion controlled by a hand lever at the side of the operator. It also has a simpling device (9), (10), and (11) fig. 7, controlled by a foot pedal, which is always us...

Re: From napkins to fabrication VFT boiler design

Valves with a rating, say "125 SWP" means that the valve is rated for "125 PSI Steam Working Pressure". 125 SWP and 150 SWP are fairly common, and other pressures can also be had. The SWP rating is needed, because many valves have seals and packing that cannot take the steam temperatures. Ebay has v...

Re: Miles per Gallon (Litre etc.)

farmerden's boat comes up to 2.9 to 3.7 MPG, not too far from the numbers developed earlier. My 20 foot sidewheeler gets about 4 MPG on Propane fuel, but the heat value of Propane is only about 66% of the heat value of No. 2 oil, (Die-sel). I think farmerden's numbers would be more representative. A...

Re: cut off

Cutoff at 50-60% of stroke will give better steam economy, and that would be the typocal cutoff values for an economic design. Running the engine with cutoff at a greater percentage of stroke will give a little more power, but will use much more steam. Most steam valve gear allows the operator to se...

Re: Miles per Gallon (Litre etc.)

In the above metnioned tests, the dimensions of the 1907 model White Steam Engine were not given. Does anyone know the bore / stroke data for this engine?

Re: Miles per Gallon (Litre etc.)

I have a few steam plant tests conducted by Massachusetts Institute of Technology (MIT) in the early 1900’s. These tests were done with then state of the art equipment, and were in pursuit of advanced engineering degrees, not sanctioned by the manufacturers, so we get a look at how the steam plants ...
