This book was released on 1977 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fuels of varying nitrogen content were tested in a T63-A-5A engine to measure their effects on exhaust gas emissions. Five test fuels varying in fuel bound nitrogen content from 3 microgram (nitrogen)/g (fuel) to 902 microgram (nitrogen)/g (fuel) were evaluated. The nitrogen content in the fuel was adjusted by mixing a JP-5 type fuel derived from shale oil (902 microgram (nitrogen)/g (fuel)) and regular petroleum JP-5 fuel (3 microgram (nitrogen)/g (fuel)). Nitrogen content of the fuel had no effect on engine performance. The carbon monoxide and unburned hydrocarbon emissions were equivalent for all the fuels included in the test program. For the engine power ratings tested, the oxides of nitrogen emissions increased with increasing nitrogen content of the test fuel. The conversion efficiency of fuel bound nitrogen to oxides of nitrogen appears to be independent of the nitrogen content of the fuel. Difficulties in measuring small changes in oxides of nitrogen level resulting from low nitrogen content fuels (50 microgram nitrogen/g (fuel) or less) caused the conversion efficiency to be very variable. The conversion efficiency for fuels with a nitrogen content of 250 microgram (nitrogen)/g (fuel) or greater was approximately 45 percent. (Author).

Book Synopsis NOx Emissions for a Gas Turbine as a Function of Fuel-bound Nitrogen and Other Variables by : William Faye
Download or read book NOx Emissions for a Gas Turbine as a Function of Fuel-bound Nitrogen and Other Variables written by William Faye and published by . This book was released on 1982 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: Emissions of oxides of nitrogen from a small (15 kW) turbine generator burning high fuel bound nitrogen fuels were measured by a chemiluminescence method. Kerosene was used as the base fuel and pyridine was added to achieve different fuel bound nitrogen levels. Mixtures of 0.0%, 0.5%, and 1.0% (by weight) of nitrogen were tested. Combustion chamber temperatures were measured with a shielded type K thermocouple inserted through the combustor can. The NOx values found were slightly lower than other studies using similar combustors. However, this can be attributed to lower combustion temperatures and to differences in fuels and combustor inlet conditions. When the NOx values were plotted against temperature they were found to fit a straight line plot quite well. This is in agreement with other subscale combustor test results. The production rate of NOx versus fuel bound nitrogen content was found to be less dependent on nitrogen content at higher temperatures than at lower values. The overall rate of production of NOx was still higher at the higher temperatures.

Download or read book Formation and Emission of Nitrogen Oxide in Gas Turbine Engines: Plume Effluent Characteristics of TF3O-P111+ and TF33-P9 Engines written by and published by . This book was released on 1996 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phase I of this project focused on the creation of a spatial emissions map of the plume effluent in the exhaust stream directly behind the engine in a jet engine test cell (JETC). Both afterburning TF30-P111+ and non-after-burning TF33-P9 engines were tested. Measurements were taken in conjunction with actual engine tests for validity of the data. Temperature, oxides of nitrogen (NOx), carbon monoxide (CO) concentration, and velocity were among the characteristics measured radially and axially in the plume for each engine type. The main focus of this study was on NOx, consisting of nitric oxide (NO) and nitrogen dioxide (NO2). Measurements in the P111+ plume reveal levels of NOx above 300 ppm along the centerline of the effluent. A dip in the NOx emissions at afterburner shows signs of a reburning and/or dilution effect by the atmospheric combustion in the effluent. Significant amounts of NO2 are present in the effluent over the entire power range. Temperatures at military power reach 1100 deg F along the centerline, and CO values are below 80 ppm. Carbon monoxide concentrations decrease from idle to military power (full power, no afterburner), then rise sharply in afterburner. The CO peaks shift outward from centerline as do the temperatures due to the radial geometry of the afterburner combustion (over 10 percent CO at 2850 deg F).

Download or read book The Control of Oxides of Nitrogen Emissions from Aircraft Gas Turbine Engines. Volume 3. The Flow Model written by and published by . This book was released on 1971 with total page 173 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of the study was to develop criteria for use in the design of aircraft gas turbine combustion chambers to minimize nitrogen oxide emissions. The approach adopted involved the development of a mathematical model of NOx emission from aircraft engine combustors; a parametric analysis, using the model, to determine the sensitivity of NOx emissions to variations of model parameters and engine design variables; evaluation of critical model parameters by means of experimental measurements; and the incorporation of the model into combustor design methods to provide guidelines for minimizing NOx emission while maintaining other performance and emission characteristics. The report describes combustion and flow processes in gas turbine combustors and a computer program (GASNOX) for calculating gas properties and NO concentrations throughout a combustor. This program is based upon a three-zone, heterogeneous model of gas turbine combustor operation. Program GASNOX is used with input data from Program NOXRAT to calculate NO emission rates.

This book was released on 1987 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: NOx are air pollutants from the testing of gas turbine engines. Out-of-airframe engine testing is regulated by air pollution control agencies which require NOx emissions data on applications for permits to construct and operate engine test facilities. Aside from continuous emissions monitoring, current methods of determining NOx emissions from test cells depend on the availability of accurate records of engine operational data. This degree of record keeping is excessive given the difficult conditions under which engine testing is normally conducted. To avoid excessive record keeping, the Aircraft Environmental Support Office recommends a simple procedure for determining NOx emissions. Its use depends only on accurate records of fuel usage for each engine test run. The procedure involves the use of a correlation coefficient which relates the weight (pounds) of NOx emissions to the weight (pounds) of fuel consumed during engine testing. The coefficient is characteristic of a given engine type, demonstrating little variation among individual engines. This report establishes a correlation coefficient for the TF41-A-2B engine based on actual emissions data and the run sheets from 27 engine tests conducted in test cells at NAS Lemoore, CA. The correlation coefficient, equal to 0.01515 pounds of NOx formed per pound of fuel consumed, determined NOx emissions to within 1% of actual values. Analysis of the statistical validity of the coefficient supports its use as a reliable procedure.
