On-load washing method for thermodynamic system

Abstract

The invention relates to a heating power system bearing load cleaning method. The feature is adding agent that has cleaning and maintaining function into agent melding trunk and diluted by desalination water. The compounding of the agent is: interface active agent 5-20%, penetrating agent 5-8%, removing agent 5-15%, dispersing agent 5-20%, surface passivator 5-10%, and the other is water. Adding the agent into system while the boiler or the steam turbine is running, the pH value is maintained between 6 and 10 while cleaning.

Description

technical field

[0001] The invention relates to a thermal system cleaning method with load, which is used for cleaning boilers and steam turbines. Background technique

[0002] The purpose of boiler chemical cleaning is to ensure the safe and economical operation of thermal equipment. Whether to carry out chemical cleaning should be determined according to the specific regulations of the relevant industries. Due to the comprehensive influence of boiler water treatment quality, boiler structure, operating conditions, working pressure, combustion mode and other factors during boiler operation, scaling on the boiler tube wall and excessive temperature of the tube wall often occur. The allowable temperature and technical indicators are the standard. After checking the pipe wall temperature and corrosion and scaling conditions, it is judged whether chemical cleaning is required. The part of the running boiler that is prone to corrosion and fouling is the fire side of the water-c...
