Electrostatic Precipitator Upgrade Opportunities
The results of stack emissions testing conducted at several coal-fired power plants during the past three years have provided useful guidance for plant operators who are required to meet new federal guidelines regarding the release of particulate matter. The data and guidelines presented here will assist those who operate plants with electrostatic precipitators to develop a strategy for filterable particulate emissions control.

Steam Turbine Rotor Vibration Failures: Causes and Solutions
Steam turbine rotors bend during operation, but the bearing and supports are designed to keep the static and dynamic forces under control. However, bending can cause impact between stationary and rotating parts—often cascading impacts. An operator of many utility-scale steam turbines shares its extensive field experience identifying the root cause of failures as well as […]

NYISO Deems Reliability in New York Safe—With Caveats
A reliability plan approved by the board of directors of the New York Independent System Operator (NYISO) on Friday concludes that additional transmission and generation resources will be needed during the study period (2013–2022) to meet system reliability criteria, but several factors could raise new impacts on reliability. These include retirement of more generation units for economic or environmental reasons, or if the Indian Point reactor’s licenses were not renewed.

Seven EU Members Faulted for Breaching NOx, SO2 Emissions Ceilings
Seven European Union (EU) member states exceeded the EU National Emissions Ceiling (NEC) Directive air pollutant limits in 2011, the European Environment Agency (EEA) said last week. The European Commission is reportedly considering initiating infringement proceedings against the countries for exceeding emissions limits for nitrogen oxides (NOx), sulfur dioxide, volatile organic compounds, and ammonia.
