Aiming at the serious salt accumulation and corrosion problems occurred on low-pressure rotor of steam turbine in a domestic heating unit

the causes were analyzed comprehensively from the aspects of steam and water quality

medicine quality

scale sample analysis and operation of thermal system. The results show that the it is the leakage of heater in heating network which makes the quality of heat-supply network drain and steam exceed the standard. To solve this problem

the corresponding countermeasures including strengthering the on-site operation management and chemical supervision were put forward to ensure the safe

stable and economic operation of the unit during the heating operation period.
