Steam Surface (Water Cooled) Condensers

Steam surface condensers for power plants ranging in output from 10 MW to 1000 MW and in the following configurations:
• Cylindrical, Inverted “U”, or Rectangular
• Axial or Down Exhaust
• Single or Multiple-Pressure
• Single or Multiple-Shell
• Divided or Non-Divided Waterbox
• One Pass or Multi-Pass

Maarky offers the following auxiliary items along with the steam surface condenser:
• Steam Jet Air Ejector System
• Liquid Ring Vacuum Pump Systems
• Waterbox Priming Systems
• Continuous Ball Tube Cleaning Systems
• Condensate Pump Systems
• Waterbox Cathodic Protection Systems
• Deaeration Systems (for large quantities of makeup water)
• Condenser to Turbine Expansion Joints

Bypass Condensers

Bypass condensers for a wide range of operating scenarios such as high pressure, low pressure, condensing only, condensing and subcooling, horizontal, vertical, constant pressure or constant level.

Feedwater Heatersmaarky feedwater heater

Maarky provides high, intermediate and low pressure feedwater heaters to the power industry for steam turbine applications ranging from 10 MW to 1,000 MW. The heaters can be designed for a variety of configurations including, but not limited to:
• Horizontal or vertical
• Channel up or channel down
• One, two or three zone
• Duplex
• Channel closure: hemi head, pressure seal or welded diaphragm-bolted cover

Heat Exchangers

Heat exchangers for unique applications with non-standard configurations, high temperature, high pressure, high cyclic service, and unusual fluid properties and materials are Maarky’s specialty.

Solar Heat Exchangers

Maarky designs meet the challenges faced by heat exchangers in solar power plants: cyclic operation, rapid startup and shutdowns, high pressure and high temperature applications, minimal shellside or tubeside pressure drop, and unconventional thermophysical properties of the heat transfer fluid.

Erection, Commissioning & Consulting Services
