Power Generation Markets
Turbomachinery
Control Solutions, LLC has experience with control retrofits on numerous
steam and gas turbines in power generation applications, including utility
and cogeneration. We have experience retrofitting the following types
of turbines: Elliott, Worthington,
Turbodyne, Dresser-Rand, GE, Westinghouse, Siemens, Mitsubishi, ABB, and
Allis-Chalmers.
The following is a
list of typical turbine applications and control modes. The list is not
meant to be all-inclusive but rather an overview of applications which
TurboControls can provide expertise and proven product solutions.
