FGD using ammonia instead of lime or limestone can achieve higher levels of SO2 removal while eliminating liquid and solid wastes.

Risk at a nuclear power plant can take many forms. Operators are concerned about factors that impact consistent, efficient energy production. Engineers are concerned about component reliability, compatibility and quality. All are focused on safety on the job. As a result, plant managers seek methods of mitigating risk. Any technique that is able to transform an “unknown” into a “known” factor is considered highly beneficial.

The continued planning, construction, and operation of combined cycle power plants (and other energy and industrial facilities) is introducing many new personnel to numerous water-related issues, including those related to cooling. A critical unit operation at many of these facilities is energy transfer in one or more cooling towers.

Across the US power markets, there are needs for new peaking capacity. Some may value peaking differently; however all markets value the main characteristics of a peaking facility: quick start/ramp rate, emissions compliance, flexible operation, and output.

Using a single primary fuel, combined heat and power (CHP) projects, often referred to as cogeneration projects, have been stalwart, self-serving suppliers of electricity and another thermal energy form to manufacturing industries for over a century.
