THE EFFECTS OF CO2, H2O, AND N2DILUTIONS ON POLLUTANTS OF SHALE GAS COMBUSTION
Increase in demands for energy and discovered huge reserves of shale gas in the world cause countries and researchers to focus on it progressively. The amount of shale gas production has begun to rise by developing the techniques of gas extraction from shale rocks recently. In this paper, the non-premixed combustion characteristic and emissions of shale gas and humid air with dilution effects are numerically investigated under different equivalence ratio, pressure and temperature. A two dimension model of cylindrical combustor is considered. It is concluded that NOxfor New Albany and Haynesville come to the maximum value at 1.025 and 1.02 of equivalence ratio and the maximum reaction temperatures are 2027 and 2014 K in turn. The rising equivalence ratio raises CO mass fractions. The increasing dilution rates decrease NOxand uplift CO mass fractions. The enhancing pressure rears NOxand diminishes CO fractions. The ascending wall temperature boosts NOx, CO and reaction temperatures. NOxand CO from environmental pollutants emerging at the end of shale gas combustion can be lowered by decreasing equivalence ratio, wall temperature, and pressure. The use of H2O dilution steps forward in compared with CO2and N2because of itsopposite effects on NOxand CO pollutants.
