Turbo power 50-300 MW Cell sealing steps with not rimed working vanes

Cell sealing steps with not rimed working low-pressure cylinder turbine vanes.
Engineering company «Lenturboremont» proposes a honeycomb seals over not rimed working vanes 2, 3 and 4 stages of both streams of low-pressure cylinder.
The design of the seal represents a set of cellular mobile segment, recruited from the slot carrying the roof. Their installation, give thanks to the structure of the cellular segment, significantly reduce the gap in the peripheral levels of not rimed working vanes (for example, from 5 mm to 3 mm) because of the lower leak.
Estimation shows that the use of the seal increases the cost of second and third stages of low-pressure cylinder, for example, 3%, the fourth step of low-pressure cylinder - 2%. The power turbine and the condenser on a raised, approximately 900 kW, while the heating - at 300 kW.
The presence of cross-cell cellular structure contributes moisture removing of the peripheral zone of wet-steam levels that will have a positive impact on reducing erosion and wear of the working blades, respectively, for an extension of their useful life.
As the volume of Developer include:
• Production of technical documentation;
• Manufacture of mobile sets of sealing segments (six levels);
• Field supervision for the implementation of projects.
In the recommended amount of the customer includes:
• Production of the six rings, canopies, in which segments of honeycomb seals are installed;
• Additional processing diaphragms third, fourth stages, and clip diaphragms of low-pressure cylinder number 1 for the installation of the Rings-visors;
• Compiling a cell in a flow of sealing of low-pressure cylinder under the supervision developer.
Ltd «ETF« Lenturboremont »can manufacture and deliver six rings-visors, with the appropriate application of Customer.
