Hello Sir,

Boiler manufacturers have the charts you need and could tell you specifics. There are lots of steam charts out here on the net, as this is well old stuff ; so its well documented. Google it. When you see a chart , You might can figure it out with a little more info as that you have to get to a working steam, to do real work you will need very dry steam which equates to very high heat. If a turbine is chosen to do the work you must choose between Impulse and reaction turbines. They require different properties from your steam in the velocity and the pressure requirements. Like so does a External combustion engine.

Perhaps, you may need to also know before you search :

What is the drive engine horse power ?

What is the duration of the run time ?

And what is the fuel type ? As that you will get specific BTU's ,from each fuel type differently.

Some Carolina Boys have a great information , calculators & reference materials online and a lesson or two available about steam, you might should search . Their link is:

I use this one a lot. I Hope , some of this helps you.

Here are some other links for steam learning

Obviously you must mean the size of the microturbine needed to turn an alternator or dynamo? Unfortunatetely I cannot find a commercially marketed steam microturbine this size. I suppose it must be custom made.

I would be grateful for a reference from anyone who knows a producer of this animal?

First decide which turbine you are going to use - condensing or backpressure. In case of backpressure turbine do the calculation in reverse order from turbine outlet to inlet assuming 70% isentropic efficiency. In case of condensing turbine assume inlet condition & calculate power generation and match the result based on iterations.
