Investigation on a Flue Gas Flow Rate Measuring Method for Draft Regulation on Boiler Operation

Abstract:

The present research targeted the measurement of flue gas flow rates in industrial boiler applications, to improve boiler efficiency in Sri Lanka. This study discussed three methodologies for flow measurement and placed significant emphasis on the benefits of thermal mass flow meters, given their accuracy and reliability, especially within low flow rates. A thorough literature review was conducted to pinpoint critical parameters involved in the generation of boiler performance: flue gas composition and draft regulation. This research spotlights the deficiency in the current measurement practices, hence, a systematic approach to develop, a cost-effective and regionally adaptable solution is presented for the flue gas flow measurement. The investigation validates the proposed measurement techniques by using a combination of theoretical analysis and CFD simulations and demonstrates that the simulated flow rates are close to calculated values, with minimum differences of 0.000461 kg/s. results imply that the optimization of flue gas flow measurement can result in significant enhancements in combustion efficiency. The research ultimately contributes to the betterment of boiler operation practices in Sri Lanka by providing recommendations for future studies and practical implementations to enhance resource management and environmental sustainability within the industrial sector.
