Real time remote monitoring and measurement of loss due to dry flue Gas for an industrial boiler

Abstract

The loss due to dry flue gas is quite considerable in boilers. This paper presents a novel method of wireless and real time monitoring of this loss in an industrial boiler. The proposed system consists of measuring the percentage of CO 2 present in the flue gas, temperature of flue gas and the ambient temperature. All these signals from the sensor are suitably conditioned and then transmitted to the central station using ZigBee communication. ZigBee is a popular wireless protocol used in process industries. At the central station the loss due to dry flue gas is calculated and displayed. At the central station, an ARM7TDMI-S is used for data acquisition and for calculating the boiler loss. In this work, not only the parameters are measured, but also wirelessly communicated to the central station for finding the loss due to dry flue gas. © 2013 Springer Science+Business Media New York.
