Grant E. Dunham is a Senior Research Engineer and Emissions Control Team Lead at the EERC, where he leads bench- and pilot-scale test projects to evaluate simultaneous NOx and particulate control, mercury control, and particulate sampling. Other responsibilities include equipment design and procurement; data analysis, interpretation, and reporting; and modeling of particle reentrainment. He received M.S. and B.S. degrees in Mechanical Engineering from the University of North Dakota. Prior to his current position, Mr. Dunham worked at the EERC as a Research Specialist in Energy Systems, where he was involved in the Catalytic Fabric Filtration for Simultaneous NOx and Particulate Control project and in Combustion Systems, focusing on the mathematical modeling of the formation of N2O in fluidized-bed combustion of coal. He also worked on modeling the fluid flow regimes of fluidized beds. Prior to the EERC, Mr. Dunham was an Energy Conservation Engineer in Lakehurst, New Jersey, where he was responsible for development and management of energy conservation projects as well as maintaining energy consumption data. Mr. Dunham’s principal areas of interest and expertise include methods of simultaneous NOx particulate and mercury control and methods of particulate sampling. He is a member of the Tau Beta Pi and has coauthored numerous publications.
