A well built COMPOUND Steam Engine

[dampfspieler]

Hi,

a very well-built compound steam engine is currently being offered on eBay Germany. The engine has a Klug reversing valve gear. It has a direct driven wet air pump and a boiler feed pump.
A few basic specifications:
HP 75 mm
LP 125 mm
Stroke 100 mm
Calculated speed: 500 rpm
The projected power at 500 rpm and 8 bar pressure in the HP valve body is 10 kW.
The engine is suitable for an 8-10 m long steamboat.

A suitable boiler should be able to produce 80–100 kg of steam per hour. A water-tube boiler should have a heating surface of 2 m².

A nice looking engine and I suspect that you have had some influence on the builder. That looks like your feed water heater solution that you posted some years ago. Very neat. For my taste, I would have rather less of the bare aluminium but that is very much a matter of cosmetics not engineering.

Looking at the other pictures on eBay, it is exquisite and what we in the UK would think of as 'the Best German Engineering'. I doubt if it will be heading in this direction though. The SBA website sales have had lots of first class kit available which is either not going or being offered at very low prices.

Hello Peter,

... I suspect that you have had some influence on the builder.

no, not at all. I found the ad while browsing ebay..

I have to agree with you about the prices for such engines, but these aren't the times for them.
I was just able to purchase a STUART No. 1 for €1,100 including shipping and import duties, which is slightly less than the current price of the casting kit from STUART Models.

Regards
Dietrich
