Syngas is being recognized as a viable energy source worldwide, particularly for stationary power generation. However, there are gaps in the fundamental understand of syngas combustion characteristics, especially at elevated pressures that are relevant to practical combustors. In this work, constant volume spherical expanding flames of three typical syngas compositions resulting from biomass gasification have been employed to measure the laminar burning velocities for pressures ranges between 1.0 and 20 bar tanking into account the stretch effect on burning velocity. Over the ranges studied, the burning velocities are fit by a functional form Su=Su0(T\/T0)\u03b1(P\/P0)\u03b2; and the dependencies of \u03b1 and \u03b2 upon the equivalence ratio of mixture are also given. Conclusion can be drawn that the burning velocity decreases with the increase of pressure. In opposite, an increase in temperature induces an increase of the burning velocity. The higher burning velocity value is obtained for downdraft syngas. This result is endorsed to the higher heat value, lower dilution and higher volume percentage of hydrogen in the downdraft syngas.<\/jats:p>","DOI":"10.1115\/1.4004607","type":"journal-article","created":{"date-parts":[[2011,9,6]],"date-time":"2011-09-06T18:02:24Z","timestamp":1315332144000},"update-policy":"https:\/\/doi.org\/10.1115\/crossmarkpolicy-asme","source":"Crossref","is-referenced-by-count":16,"title":["Measurements of the Laminar Burning Velocities for Typical Syngas\u2013Air Mixtures at Elevated Pressures"],"prefix":"10.1115","volume":"133","author":[{"given":"Eliseu","family":"Monteiro","sequence":"first","affiliation":[{"name":"CITAB, University of Tr\u00e1s-os-Montes, Alto Douro, Portugal"}]},{"given":"Abel","family":"Rouboa","sequence":"additional","affiliation":[{"name":"CITAB, University of Tr\u00e1s-os-Montes, Alto Douro, Portugal; CITAB-UTAD\/MEAM Department, University of Pennsylvania, 229 Towne Building, 220 South 33rd Street, Philadelphia, PA-19104-6391"}]}],"member":"33","published-online":{"date-parts":[[2011,9,6]]},"reference":[{"key":"2019100400285042900_c1","doi-asserted-by":"publisher","first-page":"1991","DOI":"10.1016\/j.fuel.2004.03.015","article-title":"Study of Syngas Co-Firing and Reburning in a Coal Fired Boiler","volume":"83","author":"Wu","journal-title":"Fuel"},{"key":"2019100400285042900_c2","doi-asserted-by":"publisher","first-page":"133","DOI":"10.1016\/S0010-2180(72)80234-7","article-title":"Determination of Burning Velocities: A Critical Review","volume":"18","author":"Andrews","journal-title":"Combust.
