Coal-fired power plants utilize a highly charged electric field, with the help of an electrostatic precipitator (ESP), to trap ash and other particulates. This keeps the amount of ash escaping from the plant very low. However, mercury can also be found in coal, and the ESP’s are less adept at capturing it.
In order to solve this problem, Clack has developed a method that works in tandem with an ESP, reducing the amount of mercury emitted into the air while at the same time not adding a separate process to an already complex power plant system.
Clack’s research focuses on the study, characterization, and enhancement of fluid, thermal, and mass transport processes, primarily associated with combustion and combustion emissions control.
