Turbine Inlet Cooling and Heating Coils

Fluid coils designed to meet the stringent requirements of the power generation industry

Turbine inlet cooling systems condition the incoming air to a lower temperature increasing air density and mass flow rate. The process restores the performance of the turbine to its peak capacity regardless of the weather. DRS has successfully completed Turbine Inlet Coil project installations around the world.

Heating coils are used to improve the efficiency of the GT in turn down situations, or to reduce the possibility of icing in certain regions. Marlo has provided bare tube coils as well as standard fin and tube coils for heating installations improving the performance of the GT in such diverse applications.

Our standard Turbine Inlet Coils are approved by all major turbine manufacturers and all coils feature integrated lifting lugs and fully drainable circuits. Marlo offers optional corrosion preventative coatings, materials, and flexible duct mounting hole sizes and locations. Marlo can accommodate your unique requirements.At DRS Marlo Coil we work to achieve the best value solution for our customers. We have in-house resources to help you size the equipment to meet your cooling needs and minimize air pressure drop through the system. Improve turbine performance with a quality Marlo cooling coil, the most important part of your inlet system.

TURBINE INLET COOLING

Advantages of Mechanical Turbine Inlet Cooling

Gas turbine mechnical cooling systems are used worldwide to improve power output. The power output of a gas turbine is inversely related to the inlet air temperature; as the inlet temperature increases the power output decreases. This characteristic creates less power thereby reducing output which in turn negatively affects the required performance. Turbine inlet cooling systems condition the incoming air to a lower temperature increasing air density and mass flow rate. The mechanical cooling process restores the performance of the turbine to its peak capacity regardless of the ambient temperature, humidity and availability of water.

Effects of Inlet Air Temperature on Gas Turbine Power Outlet 

Economic Benefits

The extent of the benefits realized vary with location of the turbine due to differences in ambient air temperature from one climate to another. The implementation of mechanical turbine inlet cooling provides the following benefits to the plant owner for maximizing revenue opportunities:

  • Recovery of power output lost due to high temperatures regardless of relative humidity.
  • Improvement in power generation achieved by cooling inlet air to less than or equal to 59˚F (ISO rating point)
  • Recovered power negates the need for additional power generation support.
