Analysis of the Accident of Contamination of Steam System Caused by Leakage of Urea Hydrolyser
A thermoelectric unit start-up process occurred in the urea hydrolyser heating coil leakage,the main reason is that the quality of urea is substandard,urea hydrolysate in the presence of sodium chloride corrosion of the hydrolyser heating coil and lead to fracture,urea solution through the hydrophobic recovery into the unit of the steam system,resulting in steam contamination,and ultimately make the furnace leakage of the right front screen superheater,agreed by the scheduling of the No.1 machine shutdown decontamination.
