Heat Exchange Institute: More than 80 Years of Industrial Standards

Ranga Nadig is president of Maarky Thermal Systems, which is based in New Jersey. The company provides steam surface condensers, feedwater heaters, and heat exchangers – as well as consulting services to power plants worldwide. Maarky Thermal Systems is recognized worldwide for its innovative and reliable equipment designs. The company was recently invited to join the condenser section of the Heat Exchange Institute, one of the frontrunners in developing industry standards.

Since 1933, the Heat Exchange Institute has been helping to organize and represent North American manufacturers who own manufacturing facilities or are responsible for the manufacturing of products that meet the organization’s requirements. As the Institute grew, it created a set of standards to guide manufacturers.

One of these standards applies to steam surface condensers. The performance of power plants employing wet cooling is strongly dependent on the performance of the steam surface condenser. HEI standards for steam surface condensers include guielines for thermal and mechanical design that ensures structural integrity and reliable performance.

An Overview of Solar Power Plant Operation

Maarky Thermal Systems, Inc., has set a new standard for reliable heat transfer equipment for power plants worldwide. Under the guidance of company president Dr. Ranga Nadig, Maarky Thermal Systems specializes in providing solar heat exchangers and other heat-exchange technologies to concentrated solar power plants.

Solar plants primarily use two different methods to convert solar energy to electricity. In the first method photovoltaic panels uses a series of solar cells that absorb energy from the sun and convert the solar energy to electricity.

In the second method large mirrows focus the sun’s energy to boil water to steam in boiler tubes located on top of a tall tower. Alternatively the sun’s energy can be used to heat molten salt or a working fluid such as Terminol to high temperatures. The heat from the molten salt or the working fluid is used to convert water to steam. The steam flows through a steam turbine generator producing electricity.
