Turbomachinery Package Specification Titan 250 Generator Set For combustion, the gas turbine requires approximately one-fourth of the total air it compresses. The excess air is mixed with the combustion products to reduce the gas temperature at the turbine first stage-inlet. The cooling air also keeps metal temperatures in the combustor and turbine assembly relatively low to ensure a long service life. Figure 4. Typical Combustion Process 3.1.2 SoLoNOx Combustion System The Titan 25

Turbomachinery Package Specification Titan 250 Generator Set Any variations in bus potential will also be sensed and corrected by this circuit. After voltage builds, the generator accelerates to 100% speed and excitation and voltage control is assumed by the CGCM. A crosscurrent-compensating transformer provides the signal to the CGCM for reactive loadsharing between multiple paralleled units. It should be noted that the generator rotor windings rotate and the generator armature is station
