Ammonia Turbine Search

[Peter1476]

Searching for ammonia turbines for a closed loop with outputs from 50kW to 50MW. Can anyone point me to a manufacturer's directory or a specific company? The lower range (50kW - 1MW) is the most difficult.

I remember some from the late 70's that were part of a closed loop solar energy conversion system. Part of a SBIR DOE project. Can't remember more but should be enough for start o a search.

I have never worked with ammonia turbines, but ammonia cooling units (industrial refrigerators and large air conditioning plants) used to be regularly based on ammonia asa fluid.

Wouldn't the companies that make/made those large ammonia pumps have a turbine branch? Or at least have a former turbine branch or division?

Thank you Rich and Rackoope for your comments, with the turbine shaft speed of over 20,000rpm and ammonia vapor as the working fluid, not many companies touch this. Also and more importantly for manufacturers, there isn't a big market at the moment. However, this turbine will allow higher cycle efficiencies and will attract attention.

As I recall, Capstone and Solar ( owned by caterpillar) turbine are offering microturbines for refrigerant-based cycles. The Capstone style solid state method of synching a 20,000 rpm turinbe to the grid is used to advantage in these applications. Basically , the refrigerant expansion valves are replaced with an expansion micro-turbine, to great improvement in net efficiency.

Try contacting Atlas Copco Mafi Trench, as they have built radial inflow turbines for ammonia service.
