Introduction of the SPRINT™ (Spray Inter-cooled Turbine) SYSTEM

The LM6000 gas turbines are controlled by using various parameters like the rotational speed, temperature, pressure, and other parameters. For example, compressor outlet air temperature is used as one of those parameters. This parameter is important because the compressor outlet temperature is needed to be lower than the threshold value in consideration of the cooling performance. The extracted air from the compressor is used for cooling high pressure turbine system. For example, if the intake air temperature is high, the compressor outlet temperature will also be high. At this time, the fuel supply flow is limited in order to keep the compressor outlet temperature not to be exceeded the threshold temperature, but it will also cause the power output decrease.

 

The SPRINT™ SYSTEM works to spray water at the inlets to the low-pressure compressor (LPC) and high-pressure compressor (HPC), which decreases the temperature at compressor outlet by depriving the heat of vaporization(evaporation).

 

In addition, the SPRINT™ SYSTEM enables to increase 12% power output at ISO condition when the amount of additional fuel is supplied and the temperature drops below the threshold value, or to increase 30% power output at ambient temperature of 32℃ at same condition.
