Patent application refers to auxiliary steam pipelines for autonomous starting 300 MW engine unit in TEPP ''Nikola Tesla'' Obrenovac. Starting these blocks is conditioned with work of some other block to provide feeding with the auxiliary steam of required quality, primarily steam for sealing parts of turbine that are at the start under vacuum pressure. In the case of simultaneous stopping of all blocks, starting is possible at starting one of two blocks of 200 MW engine power, that is for more reasons, risky. Alternative to this is building up the auxiliary boiler plant room, being a classical unrational approach. Building in the auxiliary steam pipeline which connects the output of intermediate boiler plant overheater and system for sealing the turbine, solves the problem explained in this invention. Therewith, intermediate boiler plant overheater is kept under pressure of 6 bars (with no steam circulation), and by coupling two flows of output boiler plant overheater in a serial line, the required temperature of about 300 °C can be achieved, and therewith obtained is a good quality auxiliary steam for sealing the turbine and for the needs of some other consumers with starting the block, and in this case " from its own source.
