Combustion Turbine NOx Control Strategies SOAPP-CT Technology Module

BACKGROUND

Nitrogen oxide (NO_x) emissions from facilities burning fossil fuels have been a source of environmental and health concerns worldwide for more than 30 years. Controlling the emissions of NO_x is an important economic decision facing companies currently burning or planning to burn fossil fuels in a combustion turbine. The main strategies for reducing NO_x/CO emissions take two forms: (1) controlling formation by modifying the combustion process and (2) removing the pollutants in the exhaust gas through post combustion treatment. This SOAPP Technology Module addresses NO_x reduction through design advances in the combustion control of combustion turbines.

SCOPE

The SOAPP-CT Technology Module on Combustion Turbine NO_x Control Strategies includes technical reference information plus interactive conceptual design models for each of the following combustion turbine NO_x control technologies:

steam injection

water injection

dry, low NO_x combustors

The module includes discussions on basic principles and the major components of combustion turbine NO_x control 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 the combustion turbine NO_x control technologies 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 NO_x emission limit

ambient dry bulb temperature

site elevation

installation type

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.
