Inlet Air Filtration SOAPP-CT Technology Module

BACKGROUND

When combustion turbines were first installed in stationary applications, the filtration of inlet air was considered an unnecessary auxiliary system. The result was numerous catastrophic failures related to the ingestion of foreign objects and the shortened service life of the combustion turbines largely due to the effects of erosion. Since no filtration systems designed specifically for the combustion turbine existed at the time, the first filtration system installations were derived from filtration systems utilized in the building HVAC industry. While these systems provided good foreign object protection, these designs proved to be lacking in erosion protection. Air filtration systems have been developed to safeguard against machinery damage and performance loss, caused by unfiltered, contaminated air and are designed to address the issue of erosion protection. This module addresses commercially viable combustion turbine inlet air filtration technologies.

SCOPE

The SOAPP-CT Technology Module on Inlet Air Filtration includes technical reference information plus interactive conceptual design models for each of the following combustion turbine inlet air filtration technologies:

pulse

multi-stage

static

The module includes discussions on basic principles and the major components of combustion turbine inlet air filtration 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 inlet air filtration system 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 control method

combustion turbine NO_x emission limit

ambient dry bulb temperature

site elevation

ambient air quality

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.
