Gas Turbines - Mechanical Drive
GE’s innovative E-class gas turbines are an excellent fit for many mechanical drive applications because of their robustness, fuel efficiency, Dry Low NOx (DLN) fuel flexibility, high mean time between maintenance, low cost per horsepower, and high power density. With heavy duty, aeroderivative and hybrid industrial gas turbines, and steam turbine offerings, GE can tailor an integrated solution to fit almost any offshore or onshore application.
How it works
A gas turbine is used to provide power to drive a rotating machine, typically a gas compressor. The gas turbine compresses air and mixes it with fuel. The fuel is burned and the hot air-fuel mixture is expanded through turbine blades, making them spin. The spinning turbine drives a compressor which converts the spinning energy into fluid pressure.
• Fuel is burned in the gas turbine
• The resulting energy in the gas turbine turns the compressor shaft
• The compressor increases the fluid pressure
For steel mill applications, a 9E Gas Turbine can drive a gas compressor that compresses low calorific and low pressure gases to the appropriate pressure required by the gas turbine combustion system. The 9E Gas Turbine provides mechanical torque to compress the steel mill gas on one side, electricity via a generator on the other shaft side and process steam via the heat recovery steam generator.
