Optimized Energy Control for Steam Generators

Abstract

This paper introduces an advanced model for optimizing energy management in steam generators used for steam production, focusing on controlling the air to fuel ratio across the entire firing curve and during transient operations. In today's world, environmental issues such as pollution and global warming are increasingly prominent due to the widespread use of electrical devices, electric vehicles powered by conventional electricity sources, and rising energy consumption. Despite these challenges, steam generators offer significant advantages such as high efficiency, reliable operation, low emissions (with regular maintenance), and flexibility in fuel sources. However, traditional maintenance practices often overlook critical parameters like the air to fuel ratio, which is crucial for achieving environmental sustainability, efficiency, and minimizing fuel consumption. The steam generator system is simulated using Simulink/MATLAB to explore its operation under various load conditions and to analyze how the air to fuel ratio changes with power output. This work has been implemented in the field on various types of burners and igniters that differ in design and fuel usage. We observed a significant improvement in the air-to-fuel ratio and a noticeable increase in efficiency. Our ongoing efforts aim to further enhance these results and improve the response time in adjustments based on the oxygen and carbon monoxide levels measured from the boiler's flue.
