TG Advisers offers state of the art start
TG Advisers goal is to reduce cold start times while maintaining or improving the safety margin of the start
Our OEM background ensures critical startup parameters are not violated and that improved industry knowledge of aged rotors is incorporated. Key elements to include are: ensuring rotor hold speeds are compliant with LP blade frequencies, high temperature rotor embrittlement is accounted for; fracture mechanics flaw growth per cycle allows remaining life targets is met, and steam superheat and allowable steam to metal temperature mismatches are not violated. TG Advisers incorporates lessons learned from industry testing on aged high temperature rotors and increases the Fracture Appearance Transition Temperature (FATT) in the embrittle zone of rotors. This ensures acceptable material fracture toughness prior to introducing significant stresses to the rotor.
