Abstract

The invention discloses a low-flow resistance double-back pressure condenser with a combining intermediate water chamber. The condenser is characterized by comprising a condenser A and a condenser B which are arranged at left and right sides of a turbine shaft in the horizontal direction; a connecting neck A is arranged on the top of a shell of the condenser A; a steam turbine connecting port is arranged on the connecting neck A; a water outlet-side water chamber is arranged at the left side of a shell of the condenser A; a connecting neck B is arranged on the top of a shell of the condenser B; a motor connecting port is arranged on the connecting neck B; a water inlet-side water chamber is arranged at the right side of the shell of the condenser B; and the shell of the condenser A and the shell of the condenser B are communicated through the intermediate water chamber. The condenser disclosed by invention has the advantages that an arrangement mode that the center line of a cooling pipe of the condenser is parallel to the axis of a steam turbine is adopted and is distinguished from an arrangement mode that the center line of a conventional cooling pipe is perpendicular to the axis of the steam turbine; on the premise of guaranteeing the operation performance of the double-back pressure condenser, the condensers are returned to the water chamber and combined; the flow resistance of condenser is effectively reduced; the length of the cooling pipe is shortened; a circulating water communicating pipe is not needed; and the plant layout space is saved.

Description

technical field [0001] The invention relates to a low-flow-resistance double-back-pressure condenser combined with an intermediate water chamber, which is suitable for an important device for maintaining the back pressure of a steam turbine and condensing the exhaust steam of a low-pressure cylinder in a heat recovery system of a thermal power unit. Background technique [0002] In modern large-scale power station equipment, the condenser is an important part of the condensing steam turbine, and its operation status will not only greatly affect the economy of the unit, but also may affect the reliability of the operation of the steam turbine unit. The main function of the condenser is to establish and maintain a certain degree of vacuum (back pressure) at the exhaust port of the steam turbine, and to condense the exhaust steam of the steam turbine into water. [0003] At present, the condensers of large-capacity units mostly adopt double-back pressure and double-shell conden...
