Available in PDF, EPUB and Kindle. Book excerpt: An automated Smoke Abatement System (ASAS) which injects a smoke abatement fuel additive into the fuel system of a gas turbine engine was developed for reducing test cell exhaust stack plume opacity caused by engine operation. The ASAS contains three major components: transmissometer to monitor plume opacity, logic/control unit which determines if opacity exceeds the standard, and variable speed pump which injects the optimum quantity of the smoke abatement additive. The difference between the plume opacity and standard regulates the speed of the pump and quantity of additive injected. The System maintained test cell plume opacity to a visual opacity of 20 percent or less during evaluation tests at two Naval Air Rework Facilities (NARF's). It is recommended that the ASAS be used to control plume opacity from those engines compatible with smoke abatement additives.

Book Synopsis Smoke Abatement for DoD Test Cells by : Bradford C Grems (III.)
Download or read book Smoke Abatement for DoD Test Cells written by Bradford C Grems (III.) and published by . This book was released on 1977 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Department of Defense owns and operates nearly 200 jet engine test cells. Occasionally, visible exhaust smoke is emitted from these structures. Several pollution control agencies, most notably the State of California, have expressed interest in limiting test cell smoke emissions. A review committee composed of various Air Force and Navy representatives recommended further study of fuel additives as a means of achieving this goal. They recognized additives as the most promising near term solution to the test cell smoke problem. Ferrocene appeared to the best of existing additives. Studies were undertaken to determine the environmental impact, toxicological hazards and engine effects associated with routine ferrocene use. Four types of Navy turbine engines were tested for ten hours each using ferrocene. These tests indicated that engines suffered no harm attributable to ferrocene, but that the additive must be certified for each engine type on an individual basis. Emission measurements made during the tests showed that most pollutants are virtually unchanged in quantity and character by ferrocene use and that particulate matter is actually reduced.

Download or read book Evaluation of the Water/Fuel Emulsion Concept for Test Cell Smoke Abatement written by Anthony F. Klarman and published by . This book was released on 1978 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Results of a test program to evaluate the feasibility of utilizing a water/fuel emulsion in gas turbine engines are presented. The objective of the program was to assess this technique as a means of controlling test cell exhaust smoke emissions at Naval Air Rework Facilities. The program was conducted on a J79-GE-10 engine and fuel control and included an evaluation of the effect of emulsions on: (a) fuel control performance and components, (b) engine performance and components, and (c) engine and test cell exhaust emissions. A water/fuel emulsion can reduce the J79-GE-10 gas turbine engine exhaust smoke to a level that will enable test cell smoke emissions to meet a 20 percent visible opacity (Ringlemann 1) standard; however, the fuel control's inability to handle the large quantities of water required (approximately 30 percent of the engine fuel flow for the J79 GE-10 engine) appears to make the use of emulsions impractical for this engine.

Book Synopsis Laboratory Evaluation of Novel Particulate Control Concepts for Jet Engine Test Cells by : R. W. Boubel
Download or read book Laboratory Evaluation of Novel Particulate Control Concepts for Jet Engine Test Cells written by R. W. Boubel and published by . This book was released on 1983 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three control devices were evaluated in the laboratory to determine their ability to reduce visible emissions from jet engine test cells. The three control devices - a low-pressure drop wet scrubber, a wetted-sand filter, and a high-temperature, ceramic fabric baghouse - were tested on the exhaust of a small gas turbine engine with a variable resistive load. Three fuel mixtures were used in experimental runs: 100 percent kerosene, 100 percent toluene, and a 50/50 blend of kerosene and toluene. Smoke number measurements of the treated and untreated exhaust stream were compared to evaluate the reduction in visual emissions for each control device. None of the three devices tested indicated enough reduction in plume opacity to justify construction of full-scale test cell control systems. Recommendations were made for future evaluation of modified wetted sand filter and ceramic fiber baghouse control devices. (Author).

Book Synopsis Abatement of Particulate Emissions and Noise from Jet Engine Test Cells Including Reduction of Gas Flow with the Test Augmenter-Scrubber System by : TELLER ENVIRONMENTAL SYSTEMS INC NEW YORK.
Download or read book Abatement of Particulate Emissions and Noise from Jet Engine Test Cells Including Reduction of Gas Flow with the Test Augmenter-Scrubber System written by TELLER ENVIRONMENTAL SYSTEMS INC NEW YORK. and published by . This book was released on 1971 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: The prototype scrubber and augmentation system designed for and operated in Black Point Test Cell Number 1 NARF-Jacksonville has abated emissions to the projected design level. The engines operated with the system were the J-79, TF-30, and J-52. Particulate emissions were reduced to the 0.002-0.005 gr/SCF level. The visible emissions fell well within the Ringleman 1/2 level after dissipation of the steam plume. No fallout was evident during operation of the system. It was further established that engine test performance was not affected by the TESI system. The scrubber system was mounted on the exhaust stack of the cell thus obviating the necessity for costly ducting and the requirement for ground utilization. The size requirement of the scrubber was reduced significantly with the use of a new augmenter design that decreased the induced air to jet exhaust flow ratio from values in the range of 2:1 to 0.4-0.6:1. This new augmenter can reduce the augmentation even further, thus providing the potential of retrofit of existing cells to accommodate engines larger than now being tested. Sound levels were reduced by the installation of the scrubber from 6-10 decibels (dBA), where the original sound level was of the order of 90-95 dBA.

Available in PDF, EPUB and Kindle. Book excerpt: The report summarizes the results of a survey and analysis of the application of conventional air pollutant abatement systems to the exhaust gas from jet engine test cells. The following methods for gas treatment were investigated: wet scrubbers, incinerators, electrostatic precipitators, filters, dry inertial collectors. The least costly methods for meeting present emission standards are water scrubbing systems. One of the most attractive of wet scrubbers using Koch Flexitrays is developed in detail. The report covers the associated problem of water supply and disposal. The report also includes research and development suggestions for test cell emission control. (Author).
