Abstract

According to the New Source Performance Standards (NSPS), particulate emissions from advanced energy conversion technologies must be less than 13 ng/J of energy input. Theoretical calculations as well as measurements made at the University of Tennessee Space Institute (UTSI) in the U.S. Department of Energy's Coal-Fired Flow Facility (CFFF) have indicated that a considerable fraction of the entrained particles in the coal-fired MHD system will be in sizes below 1 {mu}m. Thus, capturing very fine particles at an overall efficiency exceeding 99% presents a significant challenge for MHD. At the CFFF, A baghouse (BH) and a dry (ESP) are presently operated in parallel to capture such fine particulates. By the summer of 1992, a wet ESP (WESP) will be installed to replace the existing venturi scrubber/cyclone. In this paper, we have discussed the major differences between the dry and wet ESP; the principle of operation; advantages and disadvantages; and the preliminary bench scale results to identify the WESP's potential in separating soluble potassium salts.

Particulate sampling methods used at the University of Tennessee Space Institute's coal fired magnetohydrodynamic (MHD) facility

Conference Douglas, J

The University of Tennessee Space Institute (UTSI), operates a coal-fired magnetohydrodynamic (MHD) research facility with downstream components capable of simulating a steam bottoming plant with particulate control devices. The major downstream components of the coal fired flow facility (CFFF) include a superheater test module (SHTM); an air heater; and three parallel particulate control devices, a baghouse, electrostatic precipitator (ESP), and venturi scrubber/cyclone system. Major differences between MHD and conventional coal fired power plants are higher combustion temperatures of 2760{degrees}C (5000 {degrees} F) and the presence of 1% potassium in the total flow. These high temperatures and the addition of potassiummore »« less

Technical Report

In this quarterly technical progress report, UTSI reports on progress on a multi-task contract to develop the technology for the steam bottoming plant for an MHD Steam Combined Cycle power plant. Two proof-of-concept (POC) tests totaling 614 hours of coal fired operation were conducted during the quarter using low sulfur Montana Rosebud coal. The results of these tests are summarized. Operational aspects of the particulate control devices being evaluated, a dry electrostatic precipitator (ESP) and a reverse air baghouse, are discussed.

Magnetohydrodynamics coal-fired flow facility: Quarterly progress report, July--September 1988

Technical Report

In this Quarterly Technical progress report, UTSI reports on progress in proof-of-concept (POC) testing and development of the components for a magnetohydrodynamic (MHD) steam bottoming plant. The primary activities discussed are results of a 252 hour, coal-fired test in the Department of Energy Coal Fired Flow Facility (CFFF). The performance of the upstream components, which simulate the MHD topping cycle for the generation of test gases with the correct time-temperature history, was significantly more reliable than in previous tests. In the bottoming cycle tests continued on candidate superheater test module (SHTM) tube materials in three different temperature zones. The testmore »« less
