FIELD: power industry.SUBSTANCE: invention relates to power industry. The waste heat system contains a valve system made with possibility of switching between waste heat recuperation, when the entry exhaust gas is directed through the internal space of the exhaust section of the engine, and bypass position, when the said entry gas is directed via the bypass loop to bypass the waste heat boiler installed in the said internal space. Besides, the system contains the device for purging by the inert gas, made with possibility of the inert gas supply to the said internal space, ensuring removal of the residual exhaust gas from the said space. Also the option of the waste heat system and method of purging of the residual exhaust gases from the waste heat system are presented.EFFECT: invention increases efficiency of the waste heat system, and extinguishes and prevents ignition inside the exhaust pipeline.20 cl, 4 dwg |
