Development of High Response NOX Analyzer for Coal-fired Power Plants.

Engineering Development of Coal- Fired High Performance Power Systems

The current computational fluid dynamics modeling technique is capable of identifying the optimal reagent injector locations for SNCR systems. However, this technique cannot quantify NOx reduction and ammonia slip. ABB carried out a research project to investigate various computational fluid dynamics (CFD) models and the chemical kinetics of nitrogen species during coal combustion. An enhanced ...

Advanced Emissions Control Technologies for Coal-Fired Power Plants

Mercury Control Alternatives for Coal-fired Power Plants

Coal-fired power plants in the United States may have to reduce their mercury emissions by up to 90% by 2007 2009 due to proposed regulations that could affect up to 1,100 utility boilers. Air pollution control system components such as electrostatic precipitators, baghouses, NOx reduction catalysts, SO2 scrubbers, and their various configurations in utility applications significantly impact me...

Technologies for Reducing Emissions in Coal-Fired Power Plants

ly coal combustion, are major contributors to air pollution. Concentrations of suspended particles and sulfur dioxide (SO2) in the air of many cities in developing countries exceed World Health Organization standards1. The effects of this pollution on human health can be devastating and in the most seriously affected countries the economic costs are estimated to be a significant percentage of G...

Mercury policy and regulations for coal-fired power plants.

INTRODUCTION Mercury is a high-priority regulatory concern because of its persistence and bioaccumulation in the environment and evidence of its having serious adverse effects on the neurological development of children. DISCUSSION Mercury is released into the atmosphere from both natural and anthropogenic sources. Coal-fired utilities are considered to be one of the largest anthropogenic mer...
