Industries : Power Generation
Utility leaders face tremendous management, operational and growth challenges. MPW augments the power generation industry's efficiencies by designing and implementing innovative cleaning systems to control potential risks, achieve cost-savings goals, minimize outage downtime and maximize performance.
MPW's On-line/Off-line Boiler Deslagging technology surgically removes clinker build-up preventing damage to the boiler while restoring lost energy capacity and reducing the duration of planned outages. The chart below discusses the most appropriate cleaning method of coal-fired boilers, depending on the fouling.

MPW's Ultra-High Pressure (40K p.s.i.) boiler striping technology uses the dynamics of high-speed, pulsating water to remove the most adherent contaminants from boiler wall surfaces. It is proven to be the most effective application for preparing tubes for NDT (Non-DestructiveTesting) and weld overlay. UHP surface guns use less than 3 gpm, eliminating costly clean-up and disposal. Airborne particulates are not an issue, so multiple trades may work simultaneously in the boiler. From a performance perspective, MPW's boiler cleaning services increase unit efficiency, reduce NOx, emissions and reduce fouling for all downstream sections.
MPW's fleet of vacuuming equipment effectively remove coals spills in tunnels, belt lines and structures; fly ash deposits from air pre-heaters, hoppers, stacks, precipitators and ash collection points. MPW's high volume/high pressure pumps power multiple Hydroblasting guns and lances when cleaning scrubbers, heat exchangers, cyclones and economizers. Proprietary 2D and 3D tooling achieve 360º of waterjet coverage throughout the entire boiler. Cable mounted rotating nozzles run through the penthouse, covering tube walls and shafts in air preheaters, removing slag, refractory, and fly ash deposits generated from coal combustion.
The extremely seasoned engineering team of chemical cleaning specialists utilize high volume pumping equipment, heating and filtering equipment, solvent systems, and integrated chemical cleaning solutions to remove scale buildup on boilers, surface condensers, turbine blades, nozzle blocks, and areas only assessable by flow. MPW veterans provide turnkey cleaning solutions to effectively clean glycol cooling loop systems by draining, filtering, flushing and refilling them. Proprietary chemicals utilized in the cleaning process minimize generated waste.
In addition to industrial and chemical cleaning services, MPW provides high purity short-term and long-term deionized (DI) water for pre-commissioning steam blows, and for maintaining efficient HRSG operation. MPW supports existing water systems through service exchange deionization and reverse osmosis service. MPW provides expert membrane cleaning, preventative maintenance and engineering support, including emergencies, planned outages and scheduled maintenance. With MPW, you gain water quality experts while minimizing overhead costs and maintaining operational flexibility.
