HVOF Coating Case Study for Power Plant Process Control Ball Valve Applications
This is a case study of the failure of the coating on an on-off metal-seated ball valve (MSBV) used in supercritical steam lines in a power plant. The valves are exposed to rapid high-pressure and -temperature variations resulting in cracking and cohesive failure of the high velocity oxygen fuel (HVOF) 80/20 Cr3C2-NiCr coating. It was found that carbide precipitation is a major factor causing embrittlement of the coating.

Under the Proposed Clean Power Plan, Natural Gas, then Renewables, Gain Generation Share
In June 2014, EPA issued its proposed Clean Power Plan to regulate CO2 emissions from existing power plants. In May 2015, the Energy Information Administration (EIA) issued an analysis of the impacts of the proposed rule, along with this summary. According to EIA’s analysis, the main compliance strategy will be to increase natural gas-fired generation to displace coal-fired generation. Later, after 2020, as more wind and solar capacity are added, renewable generation will also surpass coal-fired generation.

Purpose of Minimum Flow by Randal Ferman, EKWESTREL - Hot Topic Hour September 11, 2014
Randal Ferman of EKWESTREL discussed the purpose of identifying “minimum flow:” 1) The lowest continuous flow the pump is permitted to operate, 2) Without reference to a specific vibration limit or other criteria, 3) The ‘default’ pump manufacturer’s recommendation. The main purposes of minimum flow are to establish permissible vibration and impeller cavitation erosion life.

Coal to Natural Gas Electric Utilities Repowering: Consequences for Valve Usage and Replacement
US power generating plants are converting from coal to other fuels in large numbers. In some cases the existing infrastructure is (to the extent possible) retained, with only the combustible material being altered. In the “middle” are plants that "repower" by using an existing turbine to run on steam from a heat recovery steam generator (HRSG) that draws (recycles) exhaust heat from a new gas turbine, together forming a combined cycle. At the other end of the scale are newly constructed power plants, which are predominantly gas-fueled. Each of these three repowering alternatives requires a different quantity of new valves, often of varying types.

Measuring Ammonia Slip from Post Combustion NOx Reduction Systems
In many facilities there may be room for process improvement that could reduce operating costs or provide revenue enhancement opportunities. Operating SNCR or SCR technology closer to its limit offers these benefits but increases the risk of high ammonia slip. The risk could be abated with the use of ammonia monitoring technology. But, except for gas-fired plants, continuous ammonia slip monitoring technologies have not been available at a practical price to facilitate these cost-saving or revenue enhancing improvements. Conditions that exist in high dust, high temperature, high NOx and/or high SO2 environments make most analyzer methods of continuously measuring ammonia unsuitable for application to coal plants. An overview of the technologies available for measuring ammonia in the high dust region downstream of a Nox reduction system and the status of their development is provided.

Constellation Energy installed SNCR systems at the CP Crane Station, units 1 and 2. These SNCR systems use continuous ammonia slip analyzers that work on the principle of tunable diode laser (TDL) spectroscopy and provide continuous, real-time indication of ammonia slip in the duct. These analyzers facilitated optimization of the SNCR system to avoid high ammonia slip transients that are the principal contributors to downstream problems normally associated with ammonia slip.
