How much does a micro gas 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.
Where is the LM6000 used?
Application examples for the LM6000 include military amphibious ships, floating production offloading vessels and LNG carriers.
What is Sprint LM6000?
SPRINT (SPray INTercooling) increases the power output of the LM6000 gas turbine by cooling the combustion air, resulting in a higher mass flow through the low-pressure compressor (LPC) and the high-pressure compressor (HPC).
How much electricity do gas turbines produce?
A large single-cycle gas turbine typically produces 100 to 400 megawatts of electric power and has 35–40% thermodynamic efficiency.
Are microturbines efficient?
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 a micro gas turbine?
Micro-gas turbines are small combustion gas turbines with power output ranging from 30 kW to over 200 kW. Hence micro-gas turbines often operate at very high shaft speed (up to 100 000 rpm) and use electronic power inverters for power conditioning to generate a.c. voltage and at grid frequency.
How does an LM6000 work?
The LM6000 provides 54,610 shp (40,720 kW) from either end of the low-pressure rotor system, which rotates at 3,600 rpm. The SPRINT system injects demineralized water into the engine either upstream of the low pressure compressor or between the low pressure and high pressure compressors.
What is the difference between aeroderivative and industrial gas turbine?
The heavy frame industrial gas turbines consume more fuel and more air than the aeroderivative units. They are exposed to a greater quantity of the contaminants in air that cause corrosion. Today aeroderivative gas turbines offer 10-15% more efficiency compared to heavy frame industrial type gas turbines.
What fuel is used in a gas turbine?
natural gas
Customarily, combustible fuels for gas turbines encompass natural gas, process gas, low-Btu coal gas and vaporized fuel oil gas (Boyce 2002). Natural gas is the most preferred conventional fuel for propulsion of gas turbines.
