Abstract

This is a study of the effect of SYNCHRONOUS COMBUSTION of gas-gasoil, achieved through the injection of gasoil droplets into NATURAL GAS flame, on the flame luminosity and radiative heat transfer. Droplets were injected by a single-hole micro-nozzle with a hole diameter of 100 mm and injection pressure of 9 bars. A photovoltaic cell was used to determine the luminous radiation and the total radiation of flame was measured by a thermopile. Also, the combination of chemiluminescence and IR photography of flame was employed to determine the qualitative distribution of soot particles in flame. The results show that the SYNCHRONOUS COMBUSTION of gas-gasoil raises the soot content of flame, leading to an increase of the luminosity and volume reaction of flame 38 and 2.5 times in comparison to the non-injection mode. Also, for the SYNCHRONOUS COMBUSTION of gasoil and gas with a mass fraction of 10%, the flame temperature changed only 95oC, whereas the flame radiation rose as much as 52%. The improvement of flame radiation in SYNCHRONOUS COMBUSTION of gas-gasoil is due to the enhancement of flame emissivity coefficient in the IR region of electromagnetic wavelengths. Meanwhile, the injection of gasoil droplets increased the CO and NO pollutants by 4 ppm and 35 ppm in comparison to the non-injection mode; due to the low mass flow rate of injection, however, the increase does not exceed the allowable limit for outlet pollution.
