Abstract

Since there has been no feasible way to remove wet flue gas of coal heating surface fouling, modern coal technology forced to raise the temperature of flue gas emissions, keep the flue gas temperature above the dew point of the flue gas acid run, so the flue gas heat abandoned lead a lot of waste. Installation in low pressure economizer cleaning device that can effectively solve the problem of fouling and plugging ash coal flue gas conditions under condensation heating surface, breaking the flue gas acid dew point restrictions on heat utilization. Analysis wet fouling shape generation and migration, and the establishment of wet fouling shape model derived shape description, and then find out the relationship between the thickness of wet fouling and heat transfer coefficient for the study of lower exhaust gas temperature, further use of waste heat is of great significance .
