CLEAN COAL TECHNOLOGY RESEARCH REPORTS
IEA Clean Coal Centre provides unbiased information on the clean and efficient use of coal world-wide, including subjects related to clean coal technology. Funded by member countries and industrial sponsors IEA CCC products include in-depth topical reports available in PDF form, a range of workshop series, the Clean Coal Technologies Conference, and online databases of coal information and resources. IEA CCC also provides direct advice, facilitation of R & D and networks.
From 1 January 2013, our reports are available as free downloads for residents of member countries or employees of sponsoring organisations. Six months after publication reports are freely available to all. Non-members can purchase reports for £100 in the first 6 months after publication. Everyone wishing to obtain a report must be registered with the IEA Clean Centre before proceeding with the download. Registrants will be notified by email when their registration is accepted (normally within one working day). Registration form.

Recent developments in particulate control, CCC/218
Research Report: CCC/218Electrostatic precipitators (ESP) are the dominant type of particulate control in pulverised coal combustion (PCC) plant; fabric filters (FF) play a smaller role. Environmental pressures and subsequent tighter regulations have lowered emission limit values (ELV) for particulate matter from PCC plant, and they are now extending to specific toxic metals, such as mercury. Lower ELV are generally met by increasing the efficiency of the existing particulate control via numerous enhancements. However, the existing fleet is ageing, various restrictions on site limit what work can be done and PCC plant is progressively operating under non-design conditions. Despite this, further developments in technology have led to significant improvements in collection efficiency and regulations have been met. New hybrid ESP/FF systems aim to become more viable than the individual technology by utilising the advantages of both technologies. The purpose of this report is to review the technical and economic considerations of enhancements in particulate control for PCC plant over the last decade.
