Gas turbine generator system

Harnessing the Hidden Potential of Our Natural Gas Distribution System Many of the innovations in green energy involve the recapture of otherwise wasted energy. Regenerative breaking systems on hybrid automobiles recapture the kinetic energy inherent in the motion of the vehicle. In a conventional automobile, as the brakes are applied, friction in the braking system converts this kinetic energy to waste heat.

Small volume production, commercial prototypes now. Courtesy of California Distributed Energy Resources Guide on Microturbines Microturbines are small combustion turbines approximately the size of a refrigerator with outputs of 25 kW to kW.

They evolved from automotive and truck turbochargers, auxiliary power units APUs for airplanes, and small jet engines. Most microturbines are comprised of a compressor, combustor, turbine, alternator, recuperator a device that captures waste heat to improve the efficiency of the compressor stageand generator.

The figure below illustrates how a microturbine works. How a microturbine works. Types of Microturbines Microturbines are classified by the physical arrangement of the component parts: The machines generally rotate over 40, revolutions per minute.

The bearing selection—oil or air—is dependent on usage. A single shaft microturbine with high rotating speeds of 90, torevolutions per minute is the more common design, as it is simpler and less expensive to build.

Conversely, the split shaft is necessary for machine drive applications, which does not require an inverter to change the frequency of the AC power.

Microturbine generators can also be divided into two general classes: Unrecuperated or simple cycle microturbines—In a simple cycle, or unrecuperated, turbine, compressed air is mixed with fuel and burned under constant pressure conditions. The resulting hot gas is allowed to expand through a turbine to perform work.

Recuperated microturbines—Recuperated units use a sheet-metal heat exchanger that recovers some of the heat from an exhaust stream and transfers it to the incoming air stream, boosting the temperature of the air stream supplied to the combustor.

Further exhaust heat recovery can be used in a cogeneration configuration. The figures below illustrate a recuperated microturbine system. Recuperated microturbine View enlarged diagram Courtesy of EPRI Cogeneration is an option in many cases as a microturbine is located at the point-of-power utilization.Capstone Turbine Corporation® is the world’s leading producer of low-emission microturbine systems.

The methane-fueled Capstone CR microturbine installed at Fallowfield Gas Processing Plant produces kW of low-emission power.
