Syngas Combustion
ISBN-13: 9783659438196 / Angielski / Miękka / 2013 / 300 str.
Bridging the gap in the fundamental understand of syngas combustion characteristics, this reference supplies experimental, modelling and simulation of equipment for syngas combustion. A review of the concepts of gasification and combustion theory is advanced. The laminar burning velocities have been determined from schlieren flame images at normal temperature and pressure, over a range of equivalence ratios and the effects of flame stretch rate through the determination of Karlovitz and Markstein numbers. Constant volume spherical expanding flames were employed to measure the laminar burning velocity at elevated pressures. A multi-zone heat transfer simulation model of the wall-flame interaction is developed in order to predict the quenching distance of typical syngas-air flames. Engine-like turbulent conditions were experimentally reproduced in a rapid compression machine. Two working procedures are shown, the single compression event and double stroke events of compression and expansion. A simulation model for the power cycle of syngas-fuelled engines has been developed. The validated model is applied to a syngas-fuelled engine in order to determine its performance.
