Optimizing air-to fuel ratios by balancing coal distribution to all burners and secondary airflow distribution, evens the burner flames across the furnace thus yielding a homogeneous temperature profile and eliminating reducing atmospheres thus optimizing combustion and reducing emissions. This demanding application requires a rugged airflow measurement system designed to meet the customers’ needs for installed boilers in the system. Air Monitor offers engineered solutions that can be installed where there are very low velocities and even when there are limited straight run duct work available.
