Abstract
Alternative fuel has attracted large focus because of environmental issues. Laminar burning speed results of syngas/air/diluent, syngas/O2/He and GTL/air/diluent premixed flames have been reviewed. In this paper, syngas consists of hydrogen and carbon monoxide and GTL (gas to liquid) is a blend of 43% n-dodecane, 25% n-decane, and 32% iso-octane. The diluent with the same specific heat as the burned gases consists of 14% carbon dioxide and 86% nitrogen. Experiments were carried out using a cylindrical chamber to observe the flame images and to measure pressure rise. The pressure rise data have been used to calculate the laminar burning speed by an integral-based multi-shell thermodynamic model for the low stretch and smooth flames. Power-law correlations were developed for experimental burning speed results of syngas/air/diluent, syngas/O2/He and GTL/air/diluent mixtures over a wide range of equivalence ratios, temperatures, pressures, and diluent concentrations. Kinetics simulations calculated by 1-D steady-state flame code from CANTERA were compared with various experimental burning speed results. The measured burning speed values are very close to the simulation calculations.
