Comparison of HAPs from advanced and conventional power systems: Tidd versus Cardinal

摘要

The goal of this project is to evaluate available hazardous air pollutant (HAP) emissions data from advanced power systems and compare those data with data from conventional systems. The specific objectives of this program are to (1) perform a technical review and assessment of the data accumulated on the fate of trace metals and other HAPs in advanced coal power systems and compare them to data on emissions from conventional pulverized coal power plants and (2) assess the effectiveness of conventional and innovative control technologies relative to potential regulation requirements. To accomplish this goal, a three-task approach has been adopted: Task 1--technical review of available data, Task 2--presentation of available data, and Task 3--assessment of control options. Each of these tasks is discussed in more detail below. The work performed on this project to date has centered around the evaluation of data from the Tidd pressurized fluid-bed combustor (PFBC) and advanced particulate filter (APF), the General Electric (GE) hot-gas cleanup unit (HGCU), and information from conventional systems. Three sets of results are summarized below: comparison of Tidd PFBC and Cardinal pulverized coal (pc)-fired combustor, comparison of Tidd APF and electrostatic precipitator (ESP) with Cardinal ESP, and summary of conventional and advanced power system collection efficiencies and emission factors.
