Hydraulic Shocks

Hydraulic shocks and instabilities occurring in condensate feed systems associated with large steam turbine generating plants have been investigated and found to be diverse in origin and character. In service instabilities are attributed, inter alia, to powerful interstage cavitation in centrifugal condensate pumps, to the penetration of unstable zones of pump suction water level, to swiftly stroking valves, to inventory shifts and the placing of pressurized systems in communication with voided systems. Shock is attributed to pumping into evacuated systems. Sustained heat transfer in steam-water and water-water heat exchangers has caused system over-pressurization during off-service conditions. Some difficulties encountered during operations are described and discussed. Recommendations are made for the elimination or minimization of trouble in existing systems and for the avoidance of trouble in future systems.

The allocation of feedwater heating in regenerative heaters is one of the important points related to the thermo-economy analysis of thermal power plants. Optimizing the allocation of feedwater heating can obtain obvious economic benefits without additional equipment investment or material consumption. Based on a modified particle swarm optimization (PSO), this paper proposes a numerical model for feedwater heating allocation problem in selecting the optimum feedwater heating allocation of large capacity steam turbine unit. A real case of a 600 MW steam turbine unit shows that the optimized results are significantly better than the original design value. The proposed method is convenient for analyzing and solving the problem of optimum feedwater heating allocation, and the results presented in this work should have important implications in the design and tapping energy-saving potential of large capacity steam turbine unit.
