The Optimization Test Study for the Vacuum System of Piping Main-Scheme in the 600MW Unit

摘要

The operation mode of dual-pressure condenser directly influences the vacuum, which makes the entire enthalpy change to affect the economy of the unit. In the vacuum system for the dual-pressure condenser, it is different for the vacuum influenced by both the piping-main scheme and the individual running, which gets along with the load. When the load is higher, the piping-main scheme running is suggested. Contrarily, the individual running is done. Compared to the piping-main scheme running, it can make the higher side pressure reduce 0.12 kPa, which is an obvious effect. The method provides the operation references for energy-saving of the plant.
