The oxygen value read by the probe is continuously compared with the set point value set on the curve. Any deviation between the 2 oxygen values (read/set point) generates a correction signal, which is transmitted to the combustion air servomotor or, if present, to an inverter that will adjust the air flow rate. Oxygen correction occurs continuously and automatically and guarantees high combustion efficiency and lower levels of harmful emissions. By continuously measuring the O2 content in the flue gas, the system is able to automatically compensate for all environmental and mechanical combustion disturbance factors, thereby ensuring a consistently high combustion efficiency. Experience in the field shows that using the O2 control can achieve an overall 3% improvement in the efficiency of the thermal unit.
