Consistent performance and reliability
Power generation needs consistent performance and reliability from plant and equipment that is subject to high-pressure loads, and breakdowns occur in boilers, feed pumps, turbines and generating systems. These are all vital components in coal-fired power generation. Components exposed to abrasive and corrosive particulate matter and gases, and components that must maintain performance levels.
Laserbond surface engineering technologies have been developed to improve availability and productivity by extending component life. When applied to impellers, thrust bearings or boiler tubes, they will increase resistance to wear and corrosion, optimise performance, extend plant and machinery operational life, and increase reliability.
This will extend component life, reduce change-outs, reduce downtime and reduce overall operating and maintenance costs.
Benefits:
Improved Efficiency
Operational efficiency delivers maximised production and output. Contributing to operational efficiency is the reliability and the continuing performance of production equipment – equipment that is subject to wear. Laserbond surface engineering technologies reduces mechanical wear in production equipment and keep efficiency levels high.
Less Unscheduled Downtime
Equipment reliability and performance is vital to achieving production goals. An unscheduled stoppage is time lost from production. Laserbond surface engineering works to maintain equipment reliability and performance levels. Reducing the disruption and risks of unscheduled downtime.
Lower Cost of Operation
Laserbond surface engineering is designed to reduce equipment from wear and erosion, extend equipment lifespan and maximise the capabilities of coated production components to reduce costs of service, maintenance and replacement parts. Lowering the overall cost of operation.
Frequently Asked Questions
What power generation components benefit from surface engineering?
Many power generation components benefit from surface engineering. Industrial gas turbines use thermal sprayed thermal barrier coatings for high efficiency. Fire-side boiler tubes are protected from high temperature and erosion through laser clad and thermal spray coatings. Ball valves, seats and HP bypass valves in power plants are other examples that rely on thermal spray and laser clad coatings to the extreme environment.
How does laser cladding and thermal spraying protect boiler tubes?
Laser cladding and thermal spraying protects boiler tubes by metallurgical upgrading the surface in contact with the boiler atmosphere. The high temperatures and corrosive gases, combined with solid particle erosion from fly ash and sootblowers demand advanced engineered materials. Instead of producing the entire tube from these materials, a coating protects the tube where it matters, on the surface.
Can turbine components be remanufactured?
Yes, turbine components can be remanufactured. Turbine shafts are thermally sprayed or laser clad to bring them back to original dimension. Turbine blades can be remanufactured through Additive Manufacturing and restoring the ceramic thermal barrier coating (TBC) by plasma spraying.
What is the benefit of surface engineering for power plants?
The benefit of surface engineering for power plants lies in extension of the operational life of critical power plant components, improving reliability for continuous energy supply. By improving wear and corrosion resistance service life is extended significantly. This reduces costly unplanned downtime and general maintenance, avoiding premature replacements. Overall, plant availability and efficiency is increased, supporting stable, uninterrupted energy generation.
