Book excerpt: Two different test apparatuses are used at BAM to evaluate the safety of oxygen components: First, the "promoted ignition combustion test" according to ASTM G 124 [1] and to EIGA IGC Doc 13/02/E [2], and second, the new "metallic disk ignition test" that has not been standardized yet. The standard test method ASTM G 124 allows a ranking of metallic materials for use at high pressure oxygen. However, the transfer of those test results to valves and fittings in real-life situations is rather complex. The "metallic disk ignition test," developed at BAM, is more practice oriented and uses metallic disks of different thicknesses of the investigated material. A commonly used nonmetallic sealing ring is placed in front of this disk and serves as an igniter. This test array is then exposed to high pressure gaseous oxygen impacts in a standardized pneumatic impact tester according to DIN EN 1797 [3].

This book was released on 2003 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper reviews some of the toxic combustion products testing, in ambient pressure, previously performed at NASA White Sands Test Facility (WSTF). The paper also presents some results from recent toxic combustion products testing in high-pressure oxygen of polymers typically used in oxygen systems. The review shows that generation of combustion toxicants is both material-dependent and temperature (or fire)-dependent. Fire conditions, the location and means of sampling, and analytical instruments used are the controlling parameters for the analysis of toxic combustion products. FTIR can provide continuous, real-time measurements of combustion product gases; however, it is difficult to obtain quantitative FTIR measurements. Appropriate sampling probe, filters, gas transfer line, and FTIR software are definitely needed. Nondispersive infrared (IR) is an effective tool for real-time carbon monoxide and carbon dioxide measurements. Combustion products analyzers (electrochemical method) and Draeger® Tubes are limited to the analysis of light combustion product gases, and they are less efficient compared with FTIR. The results of combustion testing in high-pressure oxygen environments show that combustion of polymers in high-pressure oxygen environments generated much less carbon monoxide and hydrogen cyanide. The toxic potency of the combustion gas is presumably lower than that of combustion gas generated from ambient-pressure oxygen (or air) environments.

Download or read book Promoted Combustion Testing of Pure and Ceramic Coated Metals in High Pressure Oxygen by the Federal Institute of Materials Research and Testing BAM written by C. Binder and published by . This book was released on 2006 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: The new promoted ignition combustion test apparatus at BAM matches the requirements of ASTM test method G 124 [ASTM G 124, Standard Test Method for Determining the Combustion Behavior of Metallic Materials in Oxygen-Enriched Atmospheres, 2003] and of EIGA publication, IGC Doc 13/02/E [EIGA Gas Association Document IGC Doc 13/02/E, Oxygen Pipeline Systems, 2003]. The test apparatus is most likely the only one in Europe. The test chamber allows investigations with pure oxygen or oxygen mixtures at pressures up to 500 bar and at temperatures up to 400°C at static or flowing gas conditions. The ignition device consists of an electrical ignition wire and a promoter. IR-sensors, distributed over the whole length of the rod, measure and record the burning temperature and allow measurement of the burn rate. A video system records the experiment for visual characterization of the burning behavior. BAM test results are compared with published data. Results on investigations with coated rods are presented. Ceramic coatings seem to be a solution for the use of certain less compatible metallic materials at higher oxygen pressures.

Download or read book Ignition of Metals at High Temperatures in Oxygen written by MJ. Slockers and published by . This book was released on 2006 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: Material flammability is thought to increase with increasing oxygen concentration, increasing pressure, and increasing temperature. Interest in the effects of increasing pressure and increasing sample temperature on the flammability of metals led to an industry-sponsored program for heated promoted combustion testing of metals. In this paper, the results of heated promoted combustion tests from the industry-sponsored 98-1 program are reported. Thirteen materials were tested as heated 3.2-mm (1/8-in.) diameter rods in an enriched oxygen, elevated pressure environment. Tests were performed in 100 % oxygen, and the temperature of the sample rods varied between 260 and 1093°C with test pressures ranging from 0.2 to 2.8 MPa. The test materials were 316 stainless steel, Incoloy® 800 HT, Hastelloy® C-276, Hastelloy C-22, Inconel® Filler Metal 601, Inconel Filler Metal 617, Haynes® 230, Haynes 214, Hastelloy X, 310 stainless steel, alonized Haynes 230, 304 stainless steel, and alonlzed Incoloy 800 HT.
Download or read book Promoted Ignition Combustion Tests of Brazed Aluminum Heat Exchanger Samples in Cold Supercritical Oxygen written by James White and published by . This book was released on 2016 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: A common practice in the industrial gas industry is to produce product oxygen by boiling pressurized liquid oxygen in a heat exchanger. Multistream brazed aluminum heat exchangers (BAHX) typically are used as oxygen product vaporizers. This method inherently exposes liquid and gaseous oxygen to aluminum material. Customer demands continue to increase the product oxygen pressure requirements, and it is recognized that higher pressures could increase the severity of an aluminum/oxygen combustion event. A series of experimental programs were conducted from 1993 to 1995 to evaluate the safe use of BAHX for boiling oxygen at elevated pressures to 6,996 kPa. The present experimental study is a companion test program that was conducted from 2010 to 2012 to evaluate BAHX promoted combustion response in cold supercritical oxygen to 15,602 kPa. Promoted combustion experiments were conducted with miniature headered BAHX samples. Two types of samples were tested. The first were approximately 3.3 kg, having a thinner parting sheet thickness, and the second approximately 3.9 kg, having thicker parting sheets. The oxygen passages contained commercial purity cold supercritical oxygen having a pressure ranging from 10,197 to 15,603 kPa and the adjacent passages contained cold supercritical air ("inert" fluid) at pressures ranging from 10,440 to 15,170 kPa. Tests were conducted with the air passage pressure both higher and lower than the oxygen passage pressure. Nichrome wire was used to ignite a hydrocarbon promoter located within an oxygen passage, simulating a promoted ignition-combustion event. The experiments provided insights into the combustion mitigation behavior of BAHX used for producing high-pressure product oxygen via pumped liquid oxygen (LOX) gasification. Data are applicable in supporting the safe use of BAHX for high-pressure oxygen service.
