Hi Japottinger, I'm just quoting. I've checked that I have done so correctly, and from there on I have to leave the most technical stuff to others. But a diagram I am now looking at, shows a triple exp. engine configuration with the two pipes placed exactly as the one visible above the grating, and the one indicated below here. I could read up on the matter, but I am still hoping some steam engineer will sort out this piping question. Stein
That is the inlet to the engine . It is I think a Quadruple Steam Engine and the inlet normally goes in to a chest ( i take to be H ) between the Hp ( forward of H ) and 1st IP Cylinder ( J ) and then to the 2nd IP ( Q ) the LP cyliner not being shown in the pic.
Conversley it could be a triple . In any event H is a chest not a cylinder. The HP is forward of H ; J is the next cylinder and the final cylinder shown is Q .
I agree . It is therefore a Triple expansion with the Inlet to the Hp not seen . The exhaust from Hp to Ip is Via the pipe shown to the Slide valve chest H and the exhaust from Ip to Lp is as described via pipe N below the grating to the Lp slide valve chest L . Exhaust to conderser not shown .
