Abstract

A FOSSIL FUEL FIRED POWER PLANT (PP) CAN PROVIDE AN IMPROVED DYNAMIC RESPONSE BY MEANS OF CONDENSATE STOP AND OPTIONALLY WITH INDIRECT FIRING. THE POWER PLANT (PP) HAVING A WATER STEAM CYCLE COMPRISES SIX CONDENSATE PREHEATERS (21-26) ARRANGED IN SERIES FOR THE PREHEATING BY HEAT EXCHANGE WITH STEAM EXTRACTED FROM THE STEAM TURBINES (7-10). STEAM EXTRACTION LINES (23’-26’) HAVE A QUICK-ACTION VALVE (23”-26”) ABLE TO STOP THE EXTRACTION STEAM FLOW, WHEREBY THE ADDITIONAL STEAM FLOWING THROUGH THE TURBINES ENABLES A LARGE LOAD INCREASE UP TO 10% WITHIN A SHORT TIME OF 10 SECONDS. IN CASE OF A COAL-FIRED POWER PLANT (PP), THE POWER PLANT (PP) COMPRISES A SUPPLY SILO (45) FOR PULVERIZED COAL THAT ENABLES A QUICK INCREASE IN SUPPLY RATE OF COAL TO THE BOILER (1) AND OF THE FIRING RATE. THIS ALLOWS THE LOAD INCREASE TO BE MAINTAINED OVER A LONGER TIME PERIOD. (FIGURE 2)
