Dr. Johnson received B.S. in Mechanical Engineering from Rowan University in 2003. He later received an M.S. and PhD in Mechanical Engineering from Drexel University in 2008. His research area is combustion engineering, emissions control and measurement and testing. Prior to starting professional work, Dr. Johnson worked as a guest researcher in the combustion groups at the NAVSEA and Argonne National Labs.
Over the past 9 years, Dr. Johnson has worked in the development and application of technologies for controlling emissions from combustion systems. This activity has included the design and testing of systems at 2 to 3 MBtu/hr, 20 to 100 MBtu/hr, and large industrial and utility boilers. One of these systems was a low temperature dioxin catalyst (based on conventional SCR catalysts which improved activation in relatively low temperature zones (200ºC or lower). This achieved superior processing of dioxins in low temperature zones. He has experience with combustion systems for pulverized coal, oil, natural gas, wood waste, refuse derived fuel, mass burning of municipal solid waste (MSW), and coal and oil fired diesel engines. These systems have been coupled with in-furnace NOx control, selective non-catalytic NOx reduction (SNCR), selective catalytic NOx reduction (SCR), CO oxidation and dry sorbent injection for SO2 and HCl reduction.
