SUSTAINING NEW BUILD COAL FUELED POWER WITH AIR QUALITY CONTROL SYSTEMS

摘要

Coal plays a key role in providing reliable power given its availability, output and ability to improve electrification, particularly in developing regions such as sub-Saharan Africa (SSA). However, the continued development and implementation of new build coal fueled power stations bring increased focus on environmental impacts and regulatory requirements for air emissions. Although coal fueled power generation remains a viable energy solution for Africa and other regions to help support continued economic and population growth, maintaining its position requires the implementation of air quality control (AQC) systems as part of new build generation plans and environmental considerations. The benefits of AQC implementation will help further coal’s position as an economical and reliable energy source with minimized environ- mental impact. This paper reviews available and ideal configurations of AQC systems to help minimize emissions for planned coal fueled power plants in the SSA region as well as other locations in Africa, referencing anticipated global, regional and national air pollution standards. This paper also reviews considerations for operating AQC systems with regard to reagents used, byproducts generated and operating best practices for air emissions compliance.
