Monitoring Topics Covered in August 24 Hot Topic Hour
In the hot topic hour on August 24 Mcilvaine covered several subjects important to the monitoring industry. Debbie Fox analyzed the impact of the CSAPR vacatur. Pictures of presenters and of exhibitor stands were accompanied by discussions of process monitoring in waste to energy plants, the multi metals analyzer, the MATS condundrum, boiler combustion optimization , a rapid measurement for particles in ambient air, and protocol gases, and a new SO3 monitor

Boiler MACT? - Prelude to Utility MACT by Robert Fraser, AECOM - Hot Topic Hour February 17, 2011
Robert (Bob) Fraser, QEP, Senior Technical Director for Power Generation Services at AECOM Environment, reported that the Utility MACT rule is likely to follow the form of the Industrial MACT rule which is now most likely to be issued on February 21st. EPA is using the same general procedures to develop both sets of standards. One of the concerns is the organics limits for both the Industrial and Utility MACT may be inversely rather than directly proportional to the CO. During startup and shut down there are high levels of CO and this could be a problem. It may be better to address dioxins and furans under work practice standards rather than limits.

Robert (Bob) Fraser, Senior Technical Director at AECOM Environment, discussed AECOM’s experience to date with the boiler MACT. He indicated that no one plant is now demonstrating the ability to meet all the pollutant requirements. There is very little data on CO and dioxins. It may be necessary to install back end CO and dioxin controls. These could be quite expensive. Minimizing the time at which the gas is in the 800-460 degrees F range by quenching should be effective in avoiding dioxin formation, but this is not an option where downstream fabric filters are being operated. One big question is whether a source which switches fuels to meet the MACT would then be a “new MACT source.” If a new permit is required because of fuel switching, then it is very possible that the source would be considered “new.”

Biography of Robert Fraser - AECOM Environment - Hot Topic Hour September 9, 2010
BIO: Robert (Bob) Fraser, QEP, is a Senior Technical Director for Power Generation Services within AECOM Environment. He is a Mechanical Engineer with 33 years of experience (including ten years working in industry with solid fuel combustion systems). In addition to hundreds of BACT and RACT control technology studies, he has prepared successful 112(g) case-by-case MACT demonstrations for new PC and CFB boilers, as well as MACT compliance strategy projects for over 100 solid fuel-fired industrial boilers. Bob is currently leading AECOM’s national boiler and utility MACT consulting practice.

Robert (Bob) Fraser, QEP, a Senior Technical Director for Power Generation Services within AECOM Environment, believes the proposed Boiler MACT is a prequel to the Utility MACT. Since the best utility units are better controlled than their industrial counterparts he expects a more stringent utility rule. If low CO levels are required because CO is a surrogate for organic HAPs then there may be a problem meeting NOx limits. Oxidation catalysts have not been proven for solid fuel applications with the possible exception of the Babcock regenerative catalyst for wood-fired boilers. Incinerators control dioxins using ACI, but with lower quantities of dioxinsit may be hard for the utility industry to achieve comparable percent efficiencies.
