SOAPP-CT Technology Modules
Combustion Turbine Selection
BACKGROUND
Combustion turbines, or gas turbines, have long been popular as prime movers. Their popularity continues to grow due to emerging design advances in combustion turbine generating output, efficiency, reliability, low NOx burners, and fuel flexibility. These advances have resulted in increased construction of gas turbine-based power and cogeneration plants. This module is a comprehensive review of the application of gas turbines for power generation.
SCOPE
The SOAPP-CT Technology Module on Combustion Turbine Selection includes technical reference information plus interactive conceptual design models for specific models of the following types of gas turbines:
- aeroderivative combustion turbines
- industrial frame machines
- advanced combustion turbines
The module includes discussions on basic principles and the major components of combustion turbines. More detailed information on combustion turbine 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 63 gas turbines offered by seven manufacturers as a function of the following sensitivities:
- combustion turbine model selection
- number of combustion turbines
- cycle type
- fuel selection
- secondary fuel usage factor
- 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.
