TL;DR: In this article, the authors present an overview of research related to mercury control technology for coal-fired power plants and identify areas requiring additional research and development, including the chemistry of mercury transformation and control; progress in the development of promising control technologies: sorbent injection, control in wet scrubbers, and coal cleaning; and projects costs for mercury control.

TL;DR: In this paper, the authors describe three advanced high-efficiency power systems for which the EERC has performed supporting research and development: (1) a coal-fired supercritical steam boiler with advanced emission controls; (2) an indirectly fired combined cycle using compressed air as the working fluid in a gas turbine (GT), fired either on coal alone or on coal and natural gas; and (3) two versions of a hybrid gasifier-pressurized fluidized-bed combustor (PFBC) system.

TL;DR: Ash behavior research in fluidized-bed combustion systems has been conducted to determine the effects of coal quality and operating conditions on bed agglomeration and deposition on heat transfer and other surfaces as mentioned in this paper.

TL;DR: The Air Quality III Conference on Mercury, Trace Elements, and Particulate Matter was held September 9-12, 2002, in Arlington, Virginia as mentioned in this paper, bringing together leaders from research, industry and government to address air quality issues concerning health and ecosystems, emission prevention and control, measurement methods, and atmospheric reactions and modeling.

TL;DR: The Air Quality Conference as mentioned in this paper reviewed the state of science and policy on the pollutants mercury, trace elements, and particulate matter (PM) in the environment and highlighted the role and importance of sound science to establish environmental policy.
