Abstract
Boiler Feed Water Pumps (BFWP) are considered a critical part of boilers in power plant operations. The performance of the pump in a system is estimated by one of these quantifiers in pump performance (power, efficiency, head, and flow). The design and balance of the drum in the boiler feed pump are critical for the smooth flow and optimum efficiency of the pump. The wearing tolerance limits of the drum are correlated with the type of pump and the characteristics of the system in which it is installed. A study was conducted to evaluate the drum design at Saudi Aramco Jazan Integrated Gasification Combined Cycle (IGCC) Power Block Project. The study provided a mechanism for improvement in the design issues associated with the internal clearance of balance drums related to the BFWPs. Furthermore, gradual design improvements were also implemented. Successful performance testing of Boiler Feed Water Pumps (BFWPs) fitted with upgraded balance drums was also performed. This study provides a better understanding of drum design and techniques to improve the balance of the drum.
