Shawnee test program: TVA Shawnee Test Facility. Technical progress report, April 6-May 6, 1981

Description: The test obtective for April was to evaluate sodium thiosulfate in limestone scrubber slurry as inhibitor of sulfite oxidation. The resulting effect on saturation levels of calcium sulfate (CaSO/sub 4/.2 H/sub 2/O; gypsum) and scaling in the system was of prime importance. As an antioxidant, S/sub 2/O/sub 3//sup =/ functions as a scale inhibitor by reducing SO/sub 4//sup =/, a known scale former. To meet the test objective, the scrubber was operated in a scaling mode as a base case; finally, th… more

LIMB Demonstration Project Extension

Description: The basic goal of the Limestone Injection Mitigation Burner (LIMB) demonstration is to extend LIMB technology development to a full- scale application on a representative wall-fired utility boiler. The successful retrofit of LIMB to an existing boiler is expected to demonstrate that (a) reductions of 50 percent or greater in SO{sub x} and NO{sub x} emissions can be achieved at a fraction of the cost of add-on FGD systems, (b) boiler reliability, operability, and steam production can be maintain… more

A 12-MW-scale pilot study of in-duct scrubbing (IDS) using a rotary atomizer

Description: A low-cost, moderate-removal efficiency, flue gas desulfurization (FGD) technology was selected by the US Department of Energy for pilot demonstration in its Acid Rain Precursor Control Technology Initiative. The process, identified as In-Duct Scrubbing (IDS), applies rotary atomizer techniques developed for lime-based spray dryer FGD while utilizing existing flue gas ductwork and particulate collectors. IDS technology is anticipated to result in a dry desulfurization process with a moderate re… more

Nitrogen oxide abatement by distributed fuel addition

Description: This program is designed to develop techniques for NO{sub x} abatement by distributed fuel addition. It is expected that multiple fuel and air addition in the post flame of a combustion process will increase free radical concentrations which destroy nitrogenous species as they decay toward their equilibrium concentrations. This concept will be investigated under both fuel rich and fuel lean conditions in the reburn zone. This report is a brief description of the proposed experimental plan. Resu… more

Cross-flow, filter-sorbent catalyst for particulate, SO sub 2 and NO sub x control

Description: The device described in this report will simultaneously remove particulates, SO{sub 2} and NO{sub x} from the combustion gases of coal combustors. The device is configured as a cross-flow filter. The gas flows from the inlet passages to orthogonally oriented discharge channels via thin, multilayered porous walls. Flue gas enters from both the front and back of the device. With the left wall of the filter sealed, gas discharges from the right side of the device. The key to combined physical (fly… more

Demonstration of selective catalytic reduction (SCR) technology for the control of nitrogen oxide (NOx) emissions from high-sulfur coal-fired boilers

Description: The objective of this project is to demonstrate and evaluate commercially available Selective Catalytic Reduction (SCR) catalysts from US, Japanese and European catalyst suppliers on a high-sulfur US coal-fired boiler. SCR is a post-combustion nitrogen oxide (NO{sub x}) control technology that involves injecting ammonia into the flue gas generated from coal combustion in an electric utility boiler. The flue gas containing ammonia is then passed through a reactor that contains a specialized cata… more

The Magnetohydrodynamics Coal-Fired Flow Facility

Description: Progress continued at MHD coal-fired flow facility. UTSI reports on progress in developing the technology for the steam bottoming portion of the MHD Steam Combined Cycle Power Plant. No Proof-of-Concept (POC) testing was conducted during the quarter but data analyses are reported from the test conducted during the prior quarter. Major results include corrosion data from the first 500 hours of testing on candidate tube materials in the superheater test module (SHTM). Solids mass balance data, el… more

Innovative clean coal technology (ICCT): Demonstration of Selective Catalytic Reduction (SCR) technology for the control of nitrogen oxide (NO sub x ) emissions from high-sulfur coal-fired boilers

Description: This project's objective is to demonstrate the selective catalytic reduction (SCR) process that removes nitrogen oxides (NOx) from the flue gas of boilers that burn US high-sulfur coal. The SCR technology involves the catalytic reduction of NH{sub 3} which is injected into the flue gas to react with NOx contained in the flue gas to produce molecular nitrogen (N{sub 2}) and water vapor. This quarter, work was initiated on the pilot plant ductwork layout, flue gas distribution and flow control co… more

Innovative Clean Coal Technology: Demonstration of innovative applications of technology for cost reductions to the CT-121 FGD process

Description: The objective of this project is to demonstrate on a commercial scale several innovative applications of cost-reducing technology to the Chiyoda Thoroughbred-121 (CT-121) process. CT-121 is a second generation flue gas desulfurization (FGD) process which is considered by the Electric Power Research Institute (EPRI) and Southern Company Services (SCS) to be one of the most reliable and lowest cost FGD options for high-sulfur coal-fired utility boiler applications. Demonstrations of the innovativ… more

Catalytic fabric filtration for simultaneous NO[sub x] and particulate control

Description: The overall objective of this project is the development of a catalyst-coated fabric filter for simultaneous NO[sub x] and particulate control. The catalyst-coated fabric filter must provide high removal efficiency of NO[sub x] and particulate matter. An acceptable bag and catalyst life must be demonstrated, and process economics must show a significant cost savings when compared to a commercial SCR process and conventional particulate control. Specific goals include the following: Reduce NO[su… more

Homogeneous production and removal of NO/sub x/ from combustion exhaust flows. First quarterly technical summary report

Description: The production and removal of No/sub x/ and other combustion products during fossil fuel combustion is a serious environmental problem for both stationary and mobile energy systems. Since stationary systems are faced with increased utilization of coal, oil shale, or synthetic fuel oils, all of which have significant levels of fuel-bound nitrogen, NO/sub x/ formation may become acute. Recent studies of the production of NO/sub x/ due to oxidation of fuel nitrogen indicate that a critical role is… more

Homogeneous chemistry of NO/sub x/ production and removal from fossil fuel combustion gases. Final technical report

Description: The reduction of NO/sub x/ emissions from stationary combustion sources by non-catalytic homogeneous chemical addition is a promising technique. Demonstrations in laboratory experiments and on a number of field scale combustors have shown that the addition of ammonia to the exhaust flow significantly reduces the NO concentrations in a narrow temperature range. This report summarizes the work performed to understand the detailed chemical mechanism which makes this reduction occur. A model descri… more

Nitrogen oxide abatement by distributed fuel addition

Description: Experiments were conducted to investigate the processes that influence the destruction of NO in the fuel rich stage of the reburning process. The objective is to gain a better understanding of the mechanisms that control the fate of coal nitrogen in the fuel rich zone of a combustion process. Time resolved profiles of temperature, major (CO{sub 2}, CO, H{sub 2}O, O{sub 2}, H{sub 2} and N{sub 2}), nitrogenous (NO, HCN and NH{sub 3}) and hydrocarbon (CH{sub 4} and C{sub 2}H{sub 2}) species were o… more
