DuPont™ Energy Efficiency: Emission Control & Ash Handling is part seven of the DuPont™ Energy Efficiency 16-part training series featuring DuPont owner-operator content.
The course introduces the categories of emissions and discusses the methods used to control and/or collect the most prevalent and most commonly regulated primary pollutants and by-products emitted by the combustion process in industrial-fired boilers and process equipment.
Course objectives include:
- Exercise proper safety precautions when operating emission control systems
- Classify the three basic categories of emissions
- Remove ash from the furnace using pneumatic or hydraulic systems
- Remove fly ash from the stack gases in boilers using mechanical collectors, electrostatic precipitators, and baghouses
- Understand the three general approaches used to control sulfur dioxide emissions
- Control the emission of nitrogen oxides produced in the combustion process
- Apply specific best practices to manage the energy consumption of emission control systems.
