SOAPP-CT Technology Modules

Condensate Heating

The SOAPP-CT Technology Module on Condensate Heating 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

Condensate in a combined cycle power plant can be heated prior to the deaeration process to reduce steam required for deaeration, thus increasing the steam available to generate electricity. When the first combined cycle plants were built, the benefits of condensate heating could not be justified against the low cost of the fuel. However, as fuel costs rose during the 1970s, designs that provided lower plant heat rates became more attractive. This module addresses commercially viable condensate heater configurations.

SCOPE

The SOAPP-CT Technology Module on Condensate Heating Systems includes technical reference information plus interactive conceptual design models for the following condensate heating technologies:

  • condensate heater
  • water-to-water heat exchanger
  • no condensate heating

The module includes discussions on basic principles and the major components of condensate heating 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 condensate heating technologies as a function of the following sensitivities:

  • combustion turbine model selection
  • number of combustion turbines
  • cycle type
  • fuel selection
  • secondary fuel usage factor
  • steam pressures
  • export high pressure steam flow rate
  • combustion turbine NOx control method
  • combustion turbine NOx emission limit
  • ambient dry bulb temperature
  • site elevation
  • 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.
