Foundries
Accurately monitoring airflow to maintain the proper oxygen-to-fuel ratio in metalworking foundry furnaces is complicated. Air Monitor provides engineered solutions for airflow measurement for foundries that can increase efficiency and reduce costs.
Increase Process Efficiency
Optimizing furnaces and other heating equipment in foundry applications can increase process efficiency and reduce the cost of large amounts of excess oxygen or fuel.Reduce Maintenance Costs
Reduce furnace maintenance time and costs associated with blower or burner wear with Air Monitor’s accurate Combustion Airflow Management System (CAMS™).Increase Process Control
In a fully metered Combustion Air Control System, accurate airflow measurement allows a much higher degree of control so operators can closely match the optimal air-fuel ratio.AUTO-purge III
The AUTO-purge III is designed to keep flow probes or stations clean when continuously exposed to airborne particulates, which might impair measurement accuracy. The AUTO-purge III can be programmed to periodically purge the probe arrays or stations with a high-pressure, high-volume air stream purge at the desired frequency for optimum performance of the airflow measurement system.
CAMS™ - Combustion Airflow Management System
The CAMS™ is designed as a reliable and accurate means of foundry airflow monitoring and other combustion flow applications. CAMS™ incorporates the power of the AUTO-purge III and the CAMM™ (Combustion Airflow Management Module) into a single engineered package to offer accurate combustion airflow measurement while reducing maintenance time and costs to help optimize furnace performance in industrial facility processes.
CA - Combustion Air Station
The CA (Combustion Air) Station is an engineered flow system designed for and commonly used for combustion airflow applications like optimizing furnaces and other heating equipment in foundry applications. The CA Station is ruggedly constructed with both a custom integral probe array and airflow processing cells that minimize the effect of directional airflow to get highly accurate airflow measurement in limited straight duct runs.
VELTRON DPT-Plus
The VELTRON DPT-Plus can be paired with the CA Station for ultra-low flow accuracy, direct mass flow measurement, and reliable airflow measurement in the challenging combustion airflow found in foundries.
More About Foundry Airflow Monitoring
Foundries are metalworking factories where metal is heated and formed into products. It’s valuable to have the equipment that is heating the metal working more efficiently. Usually, heating equipment like furnaces are powered through combustion.
To make the combustion process more efficient, the burners in the furnace need to be tuned for the optimal air-to-fuel ratio using a combustion control system. In a common type, the parallel positioning (PP) system, the position of the air damper is physically linked with the position of the gas valve to maintain an acceptable air-to-fuel ratio based on a process set point. PP systems eventually tend to drift away from the set point and lose accuracy.
In contrast, a fully metered combustion air control system includes measurement devices for both fuel and airflow to provide instant feedback for maintaining the air-to-fuel ratio at its most efficient point. Air Monitor’s airflow measurement technology provides highly accurate airflow measurement ideal for this process.
