Greetings to all forum participants. I"d like to share some some smail progress I"ve made on me project.Over the summer, I managed to get a steam engine running using compressed air.

When starting with a compressor producing of pressure 5 kg\ cm..I was able to get 77-78 rpm in forward gear,I got 82-84 rpm. All my subsequent adjustments failed to increase forward RPM. In addition?when pressure is applied to the first HP cylinder, strong condensation occurs and oil drip heavily from the a box. Even though I use a lot of oil. Rust builds heavily in the HP cylinder itself.There"s no rust in the LP cylinder.

I want to continue about my problem. It"s clear that condensation is occurring,and water is appearing. But why so mach water? I couldn"t imagine that such f quantity of water would be seeping through tht HP cylinder valve seal. Is this normal? Would be grateful for answers and recommendations. Ingvar.

Hello Ingvar,
the sole purpose of compressed air on steam engines is to check whether the engine runs smoothly and rotates properly.
The engine is only truly adjusted with steam, and only with steam, since its behavior differs significantly from that of compressed air.
Regarding rotational behavior in different directions - this is determined, among other things, by the design of the reversing rockers at one end.
If you want an engine that runs equally well in both directions, you must at least mount the rocker in the middle. This is done, for example, on harbor tugs.

Greetings to the forum participants! Thanks to Dietrich for the feedback, which has inspired optimism. All that remains is for me to implement your recommendation and build a boiler that produces approximately 400 kilograms of steam per hour at 10 bar. It's a challenging task. As I understand it, is it correct to assume that 10-10.5 square meters of heating surface for the Wilcox boiler tubes is sufficient? SBA Services Limited. Water Tube Boilers. The prototype of this boiler has a heating surface of 3.5 square meters. I want to use this design as a basis, more than doubling the heating surface to 10-10.5 square meters.
Merry Christmas and Happy New Year to everyone. Ingvar.
