In the light of the phenomenon that it is easy for dust to deposit on the low temperature heating surface of a bagasse-fired boiler during the actual operation process, analyzed were the operating parameters and in combination with the practical production on the spot, it has been learned that the causes for the dust deposition mainly include the following five points: a low operation temperature of the circulating water, poor effectiveness of the soot blowing system, a big water content of fuel fed into the furnace, irrational structural design of the heating surface and a big resistance of the bag dust removal device. Three concrete solutions were proposed for these special purposes, involving respectively the following: operation optimization and adjustment, construction assistance adjustment and heat exchanger structure adjustment. The foregoing can offer guidance for proper applications of the flue gas waste heat recovery technology in bagasse-fired boilers and provide reference for flue gas waste heat recovery and reconstruction engineering projects of the same kind. © 2016, Harbin Research Institute.

The authors described a novel type horizontal phase change heat exchange flue gas waste heat recovery technology and expounded its principles and main features. The technology was applied to a 135 MW unit. After the unit had been put into operation, the flue gas temperature of the boiler declined from 162 ℃ to 130 ℃, the standard coal consumption of the unit decreased by 3.44 g/(kW·h) and the water quantity saved each year was 30140 tons. ©, 2015, Harbin Research Institute.
