In the context of"dual carbon",thermal power units will inevitably put forward higher requirements for energy con-servation and emission reduction in the future;one of the important ways is to improve the unit parameters.With the phased pro-gress in the research and development of new materials with a parameterlevel of 650℃,it is possible to establish a demonstration unit for 650℃ thermal power generation.This article proposes the boiler scheme of a 1 000 MW high-efficiency ultra-supercriti-cal 650℃ coal-fired power generation unit;relevant measures have been proposed for the key technical difficulties,and puts for-ward preliminary suggestions for the selection of materials for the 650℃ high-temperature components.By developing the boiler scheme for 650℃ high-parameter coal-fired units,a good technical foundation has been laid for the implementation of future demonstration projects.
