    The flame quenching capability of four types of flame arresting devices suitable for installation on fuel cargo tank vents of marine transport vessels is evaluated. A single 30 mesh screen, a dual 20 mesh screen, a spiral wound crimped metal ribbon, and a packed bed of ballast rings were tested. Flame speed and flame penetration of the test arresters were determined. Eight fuels representative of bulk cargoes were tested. The test arresters quenched a minimum of three flashback flames from all eight fuels, with one exception: high speed ethylene flames penetrated the dual 20 mesh screen on three tests. The arresters withstood the sustained flame from a propane/air mixture for 30 minutes. None of the arresters withstood the sustained flame from an ethylene/air mixture for more than 7 minutes

    Resulting fuel, which is produced from gasoline and water, can be burned by gasoline engines with significantly reduced pollution and improved fuel economy

    Hydrogen rich gas generator

    Get PDF
    A process and apparatus is described for producing a hydrogen rich gas by injecting air and hydrocarbon fuel at one end of a cylindrically shaped chamber to form a mixture and igniting the mixture to provide hot combustion gases by partial oxidation of the hydrocarbon fuel. The combustion gases move away from the ignition region to another region where water is injected to be turned into steam by the hot combustion gases. The steam which is formed mixes with the hot gases to yield a uniform hot gas whereby a steam reforming reaction with the hydrocarbon fuel takes place to produce a hydrogen rich gas

    Ontology Mapping of PATO to YATO for the improvement of interoperability of quality description

    Get PDF
    To facilitate broad interoperability for phenotype information between different ontological frameworks, we developed a reference ontology, PATO2YATO_Quality, with the careful mapping of terms of PATO which is a quality ontology commonly used for biological phenotype annotation to the latest top-level ontology, YATO, which represents advanced modeling of quality-related concepts. As a result, YATO framework enabled to describe changes of phenotypic qualities along the courses of time in ontologically correct way and sophisticated classification and representation of interrelationships among quality-related concepts to provide fully integration of qualitative values and quantitative values obtained from phenotyping experiments and advanced representation of more detailed quality description. Thus, PATO2YATO_Quality will contribute to advanced integration of phenotypic qualities
