Gas turbine efficiency and ramp rate improvement through compressed air injection

Performance Improvement of a Regenerative Gas Turbine Cycle Through Integrated Inlet Air Evaporative Cooling and Steam Injection

Like many developed countries, energy efficiency and environment impact are the most important process in the development of power generation policy in India. A high ambient temperature reduces the air density and makes inlet air cooling (IAC) and steam injection gas turbine (STIG) attractive power augmentation method for existing regenerative gas turbine. With a high back work ratio and a high...

Case Study Gas Turbine and Duct Burner Load Control for High Ramp Rate Ancillary Services

Integration of steam injection and inlet air cooling for a gas turbine generation system

The temperature of exhaust gases from simple cycle gas turbine generation sets (GENSETs) is usually very high (around 500 C), and a heat recovery steam generator (HRSG) is often used to recover the energy from the exhaust gases and generate steam. The generated steams can be either used for many useful processes (heating, drying, separation etc.) or used back in the power generation system for ...

Influence of Altitudes and Air Humidity to the Minimum Gas Injection Rate in Air Underbalanced Drilling

Three aspects, such as the optimization of calculation model for the minimum gas injection rate, the effect of elevation on the minimum gas injection rate, the effect of air humidity on the minimum gas injection rate, have been reviewed in this paper. Considering the influence of altitude and air humidity, correction factor for gas injection rate is calculated. The value of gas injection for al...

Compressed air injection technique to standardize block injection pressures.

PURPOSE Presently, no standardized technique exists to monitor injection pressures during peripheral nerve blocks. Our objective was to determine if a compressed air injection technique, using an in vitro model based on Boyle's law and typical regional anesthesia equipment, could consistently maintain injection pressures below a 1293 mmHg level associated with clinically significant nerve injur...
