HEAT BALANCE ANALYSIS OF BAIMA’S 300MWe CFB BOILER IN CHINA
By analyzing the 336-hour performance testing period operation parameters and the actual measurement data at the scene, this paper took a study of the heat balance on Baima’s 300MWe CFB boiler. Through calculating and by the use of DL/T964-2005 standard in China, the efficiency of this boiler under the full load was 91.9089％. The result was very close to the manufacture’s assurance efficiency. In all the heat loss, the value of dissipated heat loss calculated in this paper was about 0.63％, which was higher than the manufacture’s provided value 0.25％. Besides analyzed the reason, it was discussed about the influence factors of CFB boiler’s dissipated heat loss in this paper, including the radiation areas and the out-surface temperature. Additionally, when calculated the heat loss due to the physical heat of bottom ash, the selection of output ash temperature was important. It was discussed in paper about how to choose different output temperatures for different types of ash coolers.
