Oxygen Sensors for Boiler Applications | SST Sensing - YouTube

May 27, 2021 · An oxygen sensor placed in the boiler stack can be used to control the VFD. The sensor detects the excess oxygen in the stack, and if it exceeds a set percentage, the VFD will switch the boiler fan to a lower setting to decrease the airflow. This will optimize boiler combustion efficiency. boilers.
