Stephen R. Reid, PE President and Principal Engineer TG Advisers, Inc. Gas Conversion Projects Environmental pressures have caused most US power generation owners to reevaluate both short and long term options for their coal generation assets. Retirements, repowering, upgrading emissions control technologies and conversion from coal to natural gas are the main options that are […]
Dan Skedzielewski Bill Robbins Stephen Reid, PE TG Advisers, Inc. Background The potential failure of generator rotor fan vanes and blower blades has been identified as an area for detailed risk assessment in the electric power generation industry. Liberation of fan component has caused catastrophic damage to both the rotor and stator components on a […]
Thomas R. Reid Engineering Manager Gas turbine maintenance intervals are determined by hours, starts, or a combination of both. The latter is often referred to as equivalent operating hours (EOH). The increasing integration of renewable energy sources into generation portfolios has meant changes in dispatch, and many traditionally base-loaded assets are being forced to load […]
Thermally sensitive generator rotors tend to bow and increase bearing vibration. In some cases, a rotor rewind is required to restore the unit to acceptable operating vibration amplitudes. Thermal sensitivity is usually a symptom of generator rotor winding uneven heating or uneven growth. In this article, we discuss the causes and offer general advice for […]
OPERATOR CONSIDERATIONS, BEST PRACTICES AND OPTIONS FOR OPTIMIZATION Market dynamics are dictating increased unit cycling—are you ready? By Thomas R. Reid, P.E., Manager of Engineering, TG Advisers, Inc. and John A. Moreci, MS, PMP, Principal Consultant, TG Advisers, Inc. Regardless of age or design of steam turbines, there are industry best practices to help prepare […]
Dispatching requirements for many combined cycle plants (CCP) have pushed design limits for fast starts, load and on-off cycling operations.
Based on a recent assessment of nuclear and fossil generating stations in Europe, TG Advisers identified various levels of torsional vibration concerns in more than 25 units.
Control and governor valves operate under severe service conditions. Exposure to high temperatures, erosion, water induction and low- and high-cycle fatigue can significantly reduce valve life.
