Supercritical Pressure High-performance Thermal Power PlantFeatures
S Main uses, applicable range, general versatility: Thermal power generation, which comprises nearly
60% of the world's total power generation, and particularly coal-fired power generation has beenrecognized as a stable and economical source of electric power, where supercritical pressurehigh-performance thermal power plants, which through the application of advanced technology,
increase efficiency through higher steam temperature, increase capacity, and are more compact, playa very important role.
S Energy efficiency and energy-saving effect: An energy-saving and CO2 reduction effect are obtained
from improved terminal efficiency by increased pressure and temperature steam conditions (example:25 MPa/600°C/610°C).
S Weather resistance, durability, etc.: Has mechanical reliability that has left its mark in the Guinness
Book of world records for continuous operation.
S Price advantage, originality: In the steam turbines, various measures have been taken to improve thesteam turbine internal efficiency by developing new technology, and higher performance and higher
temperatures have been achieved by using the most optimal high-strength materials and construction
suitable for high-pressure and high-temperature conditions.
In addition, in the generators, higher capacity and higher performance have been achieved bydeveloping technology for larger size and higher energy density.
