As in secondary airflow measurement applications, there are usually multiple burners used to distribute heat across the furnace and airflow must be fine-tuned for each burner to create the optimal air to fuel ratios on a burner-by-burner basis. A balancing act, this allows you to carefully stage combustion and stoichiometric ratios with micro measurement readings needed to achieve overall boiler emissions levels and efficiency. Key challenges associated in reading the dynamic airflow in this environment are caused by the mixing inherently required by a low NOx burner: vortices, angularity, and profile stratification. Air Monitor meets these challenges by offering custom individual burner airflow measurement solutions calibrated in an AMCA certified wind tunnel.
