How much does a micro turbine cost?
Microturbine capital costs range from $700–$1,100/kW. These costs include all hardware, associated manuals, software, and initial training. Adding heat recovery increases the cost by $75–$350/kW. Installation costs vary significantly by location but generally add 30-50% to the total installed cost.
How efficient are micro turbines?
Efficiency. Microturbines have around 15% efficiencies without a recuperator, 20 to 30% with one and they can reach 85% combined thermal-electrical efficiency in cogeneration.
What is PCD on gas turbine?
Compressor discharge pressure (PCD) is a key factor in gas turbine performance. Beta’s MAO service determines the deviation in PCD from a baseline relationship with gas producer speed, N1. In the case shown here, PCD looks unremarkable, but the deviation in PCD tends to be jump between -7% and -3%.
What is temperature control mode in gas turbine?
Controlling the temperature of a gas turbine limits the temperature of the exhaust gas by reducing the fuel flow, as the air flow decreases with the speed of the shaft. For a given gas turbine, the reference temperature is 513°C.
What is a Frame 6 gas turbine?
The GE Frame 6B type gas turbine is a 40 MW class gas turbine, designed for 50/60 Hz power generation and 50,000 hp class mechanical drive service. With its high-rated reliability, it is a popular choice for low installed cost power generation or prime movers in midrange service.
