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.

This book was released on 1972 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report describes a broad experimental program that was undertaken to assess the feasibility of reducing NO(x) from aircraft gas turbine engines by fuel modification. The Esso High Pressure Cannular Combustor was used to simulate the characteristic emissions of gas turbines at full power operation. Over 70 fuel modifications were tested using Jet A as the base fuel. Soluble compounds of cobalt, iron, magnesium, and copper reduce NO(x) by as much as 30% when added to the fuel at a treat rate of up to 0.5% (w). None of the investigated additives were fully acceptable because of the relatively low NO(x) reduction that was obtained even with high additive treat rates. A simple expression was derived which is useful in estimating NO levels in gas turbine combustors when equilibrium NO(x) concentrations and temperature are known.

This book was released on 2013-07 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Environmental Protection Agency (EPA) was introduced on December 2, 1970 by President Richard Nixon. The agency is charged with protecting human health and the environment, by writing and enforcing regulations based on laws passed by Congress. The EPA's struggle to protect health and the environment is seen through each of its official publications. These publications outline new policies, detail problems with enforcing laws, document the need for new legislation, and describe new tactics to use to solve these issues. This collection of publications ranges from historic documents to reports released in the new millennium, and features works like: Bicycle for a Better Environment, Health Effects of Increasing Sulfur Oxides Emissions Draft, and Women and Environmental Health.

This book was released on 2018-07-20 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Control of Air Pollution From Aircraft - Emission Standards and Test Procedures - Final Rule (US Environmental Protection Agency Regulation) (EPA) (2018 Edition) The Law Library presents the complete text of the Control of Air Pollution From Aircraft - Emission Standards and Test Procedures - Final Rule (US Environmental Protection Agency Regulation) (EPA) (2018 Edition). Updated as of May 29, 2018 EPA is adopting several new aircraft engine emission standards for oxides of nitrogen (NO X), compliance flexibilities, and other regulatory requirements for aircraft turbofan or turbojet engines with rated thrusts greater than 26.7 kilonewtons (kN). We also are adopting certain other requirements for gas turbine engines that are subject to exhaust emission standards as follows. First, we are clarifying when the emission characteristics of a new turbofan or turbojet engine model have become different enough from its existing parent engine design that it must conform to the most current emission standards. Second, we are establishing a new reporting requirement for manufacturers of gas turbine engines that are subject to any exhaust emission standard to provide us with timely and consistent emission-related information. Third, and finally, we are establishing amendments to aircraft engine test and emissions measurement procedures. EPA actively participated in the United Nations' International Civil Aviation Organization (ICAO) proceedings in which most of these requirements were first developed. These regulatory requirements have largely been adopted or are actively under consideration by its member states. By adopting such similar standards, therefore, the United States maintains consistency with these international efforts.
