Abstract

Research on lignite-fired power plants highlighted that the efficiency of lignite-fired is 88.9% for PC (pulverized coal) and USC PC (ultra-supercritical pulverized coal) units while for CFBC (circulating fluidized bed combustion) is 87.0%. The efficiency assessment carried out for the boiler presented in this paper revealed that the highest efficiency achieved in actual operating conditions is 83% while the rated efficiency is 85%. Retrofitting old boilers to reach the efficiency of modern ones, around 95% is not an option since they will not comply with environmental standards.
