| Abstract: | According to the heat balance analysis of dissolution system in Bayer proess, the deficiency and reason of heat - utilization of dissolution system in Bayer proess was discoveried. From the aspects of improving the heat transfer ef- ficiency of preheater, fomulating the reasonable thermal parameters of evaporator, improving the preheating series, clean- ing periodical of perheater scarring, the opinion to improve the heat utilization in dissolution system was addressed. |
