How to address scaling in steam turbines
Thread Content
Dear sea friends: How can scaling on air separation turbines be addressed online?
This can be addressed through regular chemical cleaning or the use of online cleaning systems; water treatment can also be improved to control the mineral content in the water and prevent scaling. .
Physical and chemical properties of the scaling substances, location of the scaling, and whether dynamic balancing is required after cleaning. For simple structures, they can be lifted out for sandblasting or treated by immersion in chemical agents. For those with complex structures, they need to be lifted out and cleaned before dynamic balancing is performed, to prevent damage to the equipment. Additionally, addressing the root cause of scaling is the most fundamental solution, for reference.
It depends on whether it is a gas turbine or a steam turbine. For steam turbines, there is no special method; the only approach is to improve the quality of the boiler feed water and to strictly control its parameters, including hardness, alkalinity, silicon, phosphorus, sodium, TOC, etc. As for gas turbines, attention must be paid to the cleanliness of the fuel, its combustion efficiency, as well as the components in the fuel that can lead to the formation of carbon deposits and solid particles. Additionally, in the case of a waste heat turbine, the flue gas needs to be properly purified. When treating scaled turbine blades and moving parts, it is necessary to first analyze the composition and structure of the scale before selecting an appropriate method for treatment. Special caution must be exercised when using mechanical methods for such treatment.
Is it a steam turbine? Our company has a new microwave-based technology for preventing and removing scale. The equipment is installed at the water inlet, where microwave signals are sent into the water within the pipes, thereby preventing and removing scale. If it is steam, the effect will be weaker, but increasing the power of the equipment should yield some effect. 13912981220
Regular testing is conducted on the water quality supplied to the boilers by the desalination station, in order to improve its quality； If scaled, it should be disassembled during maintenance to remove the scale.
