Gas Turbine Generator (GTG) in combined cycle power plant

Instrumentation for process safety and availabilty

Commercially available turbines may be either derivatives of jet engines, or heavy-duty industrial engines (typically used in Simple and Combined Cycle Power Plants). They are flexible in their operation and include features such as fast starting and load ramping, low turndown: their high full- and part-load efficiencies deliver improved plant performance. The gas turbine is the prime power source in the combined cycle using mainly gas and oil as fuels. Modern gas turbines provide more data and create far more actionable information, making them much more efficient than in the past. Advanced sensors and smarter instrumentation provide additional opportunities to utilize ‘big data’ in the form of informational and actionable analytics. Leveraging and driving these trends, KROHNE has grown its portfolio of instrumentation, software and analytics offerings to meet the needs of the digital plant of the future.

Fuel gas skids condition the fuel gas in terms of humidity and pressure regulation and incorporate necessary safety functions. Often natural gas is used as the primary energy source. The amount of fuel gas consumed needs to be measured and recorded, to meet local or national standards. ALTOSONIC V12 and OPTIMASS 6400 flowmeters, compliant to MID, OIML, AGA or other requirements, are often part of such fuel gas skids. KROHNE offers sophisticated instruments and solutions, varying from single flowmeters to complete systems like flow computers or complete fuel gas skids.
