STUDYING OF THE OPERATION STEAM CHEMICAL CLEANING OF BOILER TGMP-344A OF MINSK TPP-4
The steam chemical cleaning of the internal surfaces of the screen tubes of the boiler TGMP-344A of Minsk TPP-4 was developed by the engineers of Private Company «LvivORGRES» and implemented in production. The methods and stages of its conduct are presented. The principal scheme of operation steam chemical cleaning of the boiler TGMP-344A and its description is given. The list of devices for controlling the parameters of circulation and steam purging is presented. A table of the chemicals used for steam chemical purification was submitted. Comparative results of contaminations of heating surfaces of the boiler before and after the steam chemical cleaning are presented. It is shown that the application of steam chemical cleaning of the boiler provides a significant decreasing in the formation of new deposits on the internal surfaces of the boiler screen tubes. After using of this technology, 94 % of deposits were removed from the steam-water path of the boiler, compared with the initial contamination, and it was determined the removed amount of iron in terms of Fe2O3 is 3464 kg.
