Course overview

The startup process for boiler fan operation systems vary from plant to plant. However, most plant standing operating procedures share a similar set of activities. Pre-start preparation and post-start monitoring of the fan operation system are important pieces of an operator's job. The Combustion Air and Flue Gas System Startup training course describes the steps performed when putting the boiler fan operation system into service. This online course focuses on ID and FD fan preparation, ignitor and boiler preparation, starting the FD fans, boiler purge, and air preheaters. This course is part of the Combustion Air and Flue Gas System training series.
