SOAPP-CT Technology Modules

Heat Rejection Systems

The SOAPP-CT Technology Module on Heat Rejection Systems is an interactive, multimedia reference and evaluation tool for application of these systems in combustion turbine combined cycle plants. You can quickly make informed decisions by varying key sensitivity parameters and comparing the change in performance data, equipment sizes, capital costs, O&M costs, and construction schedule for each technology alternative.

BACKGROUND

Concern with the environmental and ecological impact from the thermal discharge of power plants to natural and man-made bodies of water grew in the 1960s and 1970s. The resulting regulatory restrictions precipitated the development of alternative technologies to once-through water cooling. This module addresses the steam condensing heat rejection system technologies used in combined cycle power plants.

SCOPE

The SOAPP-CT Technology Module on Heat Rejection Systems includes technical reference information plus interactive conceptual design models for the following heat rejection technologies:

  • surface condenser / closed cycle mechanical draft cooling tower
  • surface condenser / once-through cooling
  • air-cooled condenser

The module includes discussions on basic principles and the major components of heat rejection systems. More detailed information on each technology, including unique processes, components, and supporting systems, is also included in this module.

Technology performance; equipment sizing; capital, O&M, and differential fuel costs; and construction schedules are modeled for each of the heat rejection system technologies as a function of the following sensitivities:

  • combustion turbine model selection
  • number of combustion turbines
  • cycle type
  • primary fuel selection
  • combustion turbine NOx control method
  • combustion turbine NOx emission limit
  • maximum ambient dry bulb temperature
  • maximum ambient wet bulb temperature
  • site elevation
  • maximum unit cooling water temperature
  • unit capacity factor

Economic analyses are based on a static set of standard economic parameters when this module is used as a separate program. When this module is launched from within the SOAPP-CT WorkStation, up to 42 project-specific economic parameters are automatically imported into the module for the user's selected project. Included in these economic inputs are fuel cost, escalation rate, tax rate, capital structure, and contingencies. Default values for all module sensitivity parameters are also set from the values stored in user's selected project when this module is launched from within the SOAPP-CT WorkStation.
