Abstract: In the design of the 1000MW level ultra supercritical units in Power Plant B of Shenhua Guohua Zheneng Power Generation Company Limited, the economical and environment protection indexes were considered sufficiently, and the thermal cycle efficiency of the units is higher. In order to improve economic efficiency of the units further, some measures, such as the technical reformation, the optimization of the unit operation mode and the standard operation, were adopted, and obvious results of energy conservation and emission reduction were obtained. The indexes of 1000MW level units in energy conservation and environment protection are improved significantly.

Key words: 1000MW level unit, ultra supercritical unit, energy conservation and emission reduction, technical reformation, optimized operation
