An electronic sensor is inserted into the boiler flue, near the boiler, ahead of any dampers or other sources of air leakage into the boiler or flue. The sensor is connected to a control panel that measures oxygen and sends a signal to a control damper on the burner air supply. From the Hays Cleveland OXY-MIZER™ data sheet:

In order to achieve optimum control, both steam and feedwater flow values should be corrected for density. Notes: The three-element system provides tighter control for drum level with fluctuating steam load. Ideal where a system suffers from fluctuating feedwater pressure or flow; More sophisticated level of control

A very common control problem, and one used in many examples elsewhere, is that of controlling the level in a boiler drum. Many industrial plants have boilers for generating process steam, and of course boilers are central to thermal power generation. The boiler drum is where water and steam are separated.
