The problem of energy resource waste exists in the due and retired shutdown of the coal-fired unit. The components of the domestic and foreign coal-fired units are designed with conventional strength rather than limited service life, and the service life of the units is determined to be 30 years according to general experience. The service time of foreign coal-fired units is more than 30 years. The average service time of the coal-fired unit in active service in China is only 12 years, and the coal-fired unit which runs for more than 30 years is less than 1.1 percent. At present, 30 ten thousand kilowatt and 60 ten thousand kilowatt coal-fired units in 20-30 years of service in China reach or approach the design life, and the units are subjected to multiple times of safe, energy-saving and environment-friendly reconstruction, so that most of the units have good health conditions and have the capability of continuous operation. In part of regions, the unit which is up to 30 years in operation but reaches the environmental standard and has better energy consumption and reliability index is forcibly shut down one by one, which causes huge waste.
