excess air for wood fired boilers

Oxygen Control | CleanBoiler.o

The probe has an accuracy of ± 2% net excess oxygen and a response time within one second. The probe failure reading is above 16%, where other less accurate and stable probes fail to 0%. The OXY-MIZER™ failure reading eliminates confusion between probe failure and boilers operating with low excess air.

How to Run a Coal Fired Boiler at the Best Efficien

Pulverized coal fired boilers the total losses account to about 12 to 14 %. Roughly 50% of the losses can be tuned to the optimum and the other 50 % is governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions. The main two losses in boiler that can be tuned by operator are carbon loss and dry gas loss.
