Embodiment Construction
[0013] Description will be made below in conjunction with the accompanying drawings. The invention provides an improvement measure for an ultra- or ultra-supercritical coal-fired power generation thermal system, and relates to an economizer-free ultra- or ultra-supercritical boiler and its power plant thermal system and parameter configuration. In FIG. 1 , the system includes a coal-fired boiler 1 , a steam turbine 2 , a feedwater recuperation heater system 3 , a condenser 5 , a condensate pump 6 and a feedwater pump 7 . The economizer 8 (the middle position on the left in the figure) necessary for the conventional coal-fired unit boiler is removed, and a first-stage high-pressure feed water recuperation heater 4 is added at this position (#4 high addition in Fig. 1), because the economizer 8 is removed. The temperature of the feed water entering the water wall after the coal burner will decrease, which will affect the average temperature of heat absorption and the heat load r...
