Taking control of air flow
Efficient and optimal process control requires precise and reliable process information. This is particularly true for the air flow distribution in a thermal steam generating unit. The challenge is to achieve perfect mixing of the air and the fuel at the individual burners, as this has strong repercussions on efficiency, emissions and combustion quality. Conventional air flow measurement technology reaches its natural limits when equipping an entire boiler. Not only is it too costly to install, the maintenance burden is very high, and, above all, the readings are not as accurate and robust as required over the entire operating range.
This is where EUsoftair steps in, a next generation virtual sensor. Essentially, it is a clever piece of software that continuously determines the complete air flows from readily available DCS data. By using all relevant information EUsoftair provides a robust signal that can be used to replace conventional air flow measurement technology. This approach not only applies for steam generating units but for every application where air or other gaseous media are measured.
