The difference of steam parameters between nuclear power turbine and thermal power turbine

The steam parameter of PWR nuclear power plant is generally much lower than that of thermal power plant. For example, at present, the initial steam parameters of large steam turbines in conventional power stations are all above 16.5MPa and 538℃, and the steam parameters of some supercritical units have exceeded 25MPa and 600℃. The main steam pressure of a steam turbine in a pressurized water reactor nuclear power plant is usually 6-7 MPa, and the initial temperature is 260℃-285℃.

Second, nuclear power turbine sealing problem

Because the steam pressure and temperature of nuclear power plant steam turbine are lower than that of conventional power plant steam turbine, the curing speed of cylinder sealant is required to be higher. If the conventional power station steam turbine cylinder sealant is used, it is easy to produce steam leakage because of the high curing temperature and slow curing speed required by the sealant.

POWEROX90X high temperature turbine cylinder sealant is a special nuclear power cylinder sealant independently developed and produced by Shanghai POWEROX90X New Material Technology Co., Ltd. for the characteristics of nuclear power turbine. The product has a temperature resistance of 580℃ and can be cured quickly at rising temperature. It is suitable for nuclear power turbine and industrial turbine as well.
