Title: Method for cleaning and passivating working medium path of once-through boiler
Inventor: STOROZHUK ALEKSANDR A
IPC: F28G13/00
Filed: 1993-08-06
Granted: 1996-07-20
Abstract: FIELD: thermal engineering; post-installation and in-service cleaning and passivation of once-through boiler working-medium path. SUBSTANCE: cleaning is made during boiler starting by introducing oxiduzer into feedwater upstream of built-in gate valve and into steam downstream of built-in gate valve. Upon introducing oxidizer, stop of iron oxide emission from heating surfaces upstream and downstream of gate valve is noted whereupon working medium is periodically transferred to steam-water mixture condition by disconnecting boiler burners in path upstream of gate valve and increasing water flow to injecting desuperheaters in path downstream of gate valve until additional emission of iron oxides is stopped.
