Abstract
The utility model relates to a throat of a condenser of a steam turbine, which is applied to the home-made introduction type 300MW steam turbine. The utility model is formed by the surrounding of steel plates, bracing pipes with 5-6 layers are lined inside the steel plates, flow guide plates are fixed on the bracing pipes and are arranged between the bracing pipes of a first row and a second row and between the bracing pipes of a third row and a fourth row in a tilting way. The flow guide plates with molded lines are arranged in a direction which is perpendicular to a central line of the steam turbine, and the plane flow guide plates are arranged in a direction which is in parallel with the central line of the steam turbine. The flow guide plates are additionally arranged on the product, the molded lines of the flow guide plates are transformed, the heat load of a copper pipe of the condenser is even, the vacuum degree of the condenser is enhanced, the efficiency and the output of an assembly is enhanced, and accordingly, the service life of the bracing pipes of the throat of the condenser and the copper pipe of the condenser is enhanced.
Description
The utility model relates to a kind of home-made imported type 300MW turbine condenser throat.
At present this kind steam turbine is not established guide ring because low pressure (LP) cylinder has adopted radially exhaust structure again in the diffuser pipe part, simultaneously the throat of vapour condenser also cross setting a large cylinder, in adorn 7
#And 8
#Low-pressure heater, thus make vapour condenser inlet flow field extremely inhomogeneous.Its shortcoming has two: 1, shortens working life of condenser throat stay tube and condenser copper tube in the steam discharge main flow area; 2, make the heat load of condenser copper tube inhomogeneous, reduced the degree of vacuum of vapour condenser, promptly reduced the efficient of unit and exert oneself.
The purpose of this utility model provides the turbine condenser throat that a kind of condenser duty is even, degree of vacuum is high, and it can effectively improve the working life of condenser copper tube.
For achieving the above object, the technical solution of the utility model is: a kind of turbine condenser throat, surround by steel plate, liner 5-6 layer stay tube, fixing guide plate on stay tube, guide plate is arranged between the stay tube and is inclined to set first row and second row, the 3rd row and the 4th, has the guide plate of molded lines perpendicular to the setting of steam turbine centerline direction, is parallel to the steam turbine centerline direction plane guide plate is set.
The utility model has been set up guide plate owing to adopt said structure, conversion the molded lines of guide plate, make the heat load of condenser copper tube even, improved the degree of vacuum of vapour condenser, promptly improved the efficient of unit and exert oneself, thus the working life of having improved condenser throat stay tube and condenser copper tube.This improvement is in 3 of Tieling Power Plant
#Implement on the machine, facts have proved that the uniformity of steam discharge improves greatly, as a result ideal.
Fig. 1 is a structural representation of the present utility model.
Below in conjunction with accompanying drawing embodiment of the present utility model is described further: a kind of turbine condenser throat, surround by steel plate, liner 5-6 layer stay tube 3, fixing guide plate on stay tube 3, guide plate 1 is with being inclined to set with second row, the 3rd row and the 4th row's stay tube first row, have the guide plate 1 of molded lines perpendicular to the setting of steam turbine centerline direction, be parallel to the steam turbine centerline direction plane guide plate 2 is set.When steam flow passed through condenser throat, because the effect of molded lines guide plate and plane guide plate makes condenser duty even, the exhaust uniformity improved greatly, thereby has improved the degree of vacuum of vapour condenser, has increased the working life of vapour condenser.
Claims (3)
1, a kind of turbine condenser throat is surrounded by steel plate, and liner 5-6 layer stay tube is characterized in that on stay tube fixedly guide plate.
2, turbine condenser according to claim 1 throat is characterized in that guide plate arranges between the stay tube and be inclined to set first row and second row, the 3rd row and the 4th.
3, turbine condenser according to claim 1 throat is characterized in that having perpendicular to the setting of steam turbine centerline direction being parallel to the guide plate of molded lines the steam turbine centerline direction plane guide plate is set.
