Adams 10x10 steam engine question

Anonymous-0 · Feb 9, 2010

I have an Adams 10"x10" stationary steam engine.Does anyone know what RPM it was designed to run at?

steam engines are not the most efficient at higher speeds as you cant push enough steam through the steam chest very fast. Figure less than 1000 rpm, probably closer to 500 rpm or less max, but it is wholly dependant upon its application! Remember, a steam engine has power both on the up-stroke and the down-stroke, so it can produce alot of torque at low rpms as long as your steam is hot & dry and up to pressure

It has a 4' and a 3' pulley on the crankshaft, maybe 200-300 RPM would be fast enough.

Lower the stroke, the lower the RPM. If ran too fast the cross head will want to rock in the way and the rod gets a lot of up and down force at 1/4 stroke from TDC. Steam engines are more about torque than horsepower anyway.

Steam has the same power at 5RPM as ti does at 500 RPM.
