At the beginning of July we made a significant modification of the cross-over pipe (pipe connecting medium and low pressure turbine parts) of the 16K260 condensing turbine in one of the largest power plants in Poland.
The purpose of the modernization was to install additional, regulated steam collector for heating purposes. Additional elements for installation include a T-connector and butterfly valve with actuator. This conversion, together with the additional fittings, will allow the future use of heat for heating purposes from the condensation block.
Implementation of modernization had to ensure, a.o. maintaining the mutual position of the flanges (parallelity and distance of surfaces, angle of rotation) on the SP and NP sides, and because of the dimensions and tolerances it was a real challenge for our comapny. As a consequence, the shuttle had to be cut in several places and re-welded in a new configuration with new elements. Thanks to the excellent work of WWTECH’s engineers the task was completed in few days ahead of schedule.
