The significance of this study is rooted in the need to enhance the energy efficiency of seawater desalination processes, which not only reduces costs but also benefits the environment. A key component of this efficiency lies in understanding how brine boilers perform. The thermal efficiency of these boilers is a pivotal element in the desalination of seawater, a process vital for addressing freshwater shortages globally. The performance of desalination facilities heavily relies on the efficiency of the boilers used. Critical factors include the thermal value of the energy and the temperature of the gases produced during combustion. High thermal value energy can boost heat production, thereby improving boiler efficiency. Additionally, the temperature of combustion gases influences the heat recovery process, impacting the overall efficiency of desalination stages.
The thermal value of the energy and the temperature of the gases produced significantly affect the efficiency of seawater desalination boilers. Utilizing high thermal value energy enhances the process due to superior energy quality. Furthermore, elevated gas temperatures aid in the preheating of seawater, thereby optimizing efficiency. In thermal desalination processes like Multi-Effect Distillation with Thermal Vapor Compression (MED-TVC), considering ocean water temperature and salinity conditions can further enhance energy efficiency and performance. Hence, advancements in energy quality, gas temperature, and operational standards can profoundly influence the efficiency of desalination facilities.
Calculating thermal efficiency is crucial for assessing boiler performance and its effectiveness in converting and utilizing thermal energy. Consequently, examining the impact of the thermal value of energy and gas temperature on the efficiency of the Zliten brine factory's boiler was essential.
The analysis of available data and the discussion of potential outcomes from applying the total thermal value of energy and gas temperature were vital for achieving optimal boiler efficiency. The efficiency of the brine boiler at the station was determined to be 82%, based on real data from the facility, reflecting its actual performance. The relationship between boiler efficiency, the heat generated by energy, and the combustion temperature was thoroughly examined. The findings revealed that the calculated efficiency closely matched the actual efficiency, confirming the accuracy of the methods and equations used. These results are invaluable for assessing and understanding the factors influencing seawater boiler efficiency.
