Field Demonstration of Reduced Load Selective Catalytic Reduction Operation
Because of low natural gas prices, many coal plants are being asked to operate at low loads, which may present technical challenges for selective catalytic reduction reactors used for NOx control. Vendors set a minimum operating temperature to protect the catalysts in the reactors. The objective of this research was to demonstrate that the reactors […]

Case Studies in Flexible Operations of Combined-Cycle and Simple-Cycle Plants—2015 Update
Increasing renewable generation has forced combined-cycle and simple-cycle fossil plants to start more frequently, operate over a greater load range, and provide load-balancing. This report updates a 2014 report with two additional plant case studies on flexible operation strategies and technologies.

Rapid Response Absorber
Commercially available acid gas removal systems can capture CO₂ from the gas stream of coal-fired power plants, but they are designed for baseload operations. This report assesses an improvement in the system design that could result in more operating flexibility. The results are a first successful step to develop a rapid response CO₂ absorber for […]
