Abstract

Boiler feedwater pumps are among the most energy-intensive auxiliary parts in steam boiler plants. Maintaining high availability and reliability has traditionally dominated the optimal design of the boiler feedwater pumping system. The operation of thermal power plants under variable load, e.g. due to the introduction of intermittent renewable energy sources, imposes additional energy losses on the pumping systems. This study aims to establish an algorithm to optimize energy consumption, consequently, life cycle costs of the boiler pumping system under cyclic operation. A mathematical model is presented for the analysis and optimization of various boiler pumping systems, including single and multiple pumps in constant or variable speed. The results indicate considerable potential for energy savings up to 20% by the optimization of stage numbers, pump numbers in parallel, booster pump characteristics, and drive's speed.
