A flare system is installed for the enhancement of process safety, and the stable combustion is one of the most important elements. The main function of the flare system is the combustion of the flammable or toxic materials into non-hazardous materials, but combustion heat is released from a flare system. In this study, the effect of the external and internal steam injections in the flare stack on the reduction of the thermal radiation was investigated. The ignition possibility by the change of steam amount and the effect of the steam on the thermal radiation were also analyzed by using consequence analysis software. In case of thermal emission of oil refinery plants through improved steam injection, the injection of 120% steam rather than the conventional method enabled the reduction of the flare stack height. It could reduce the height of flare stack by 20%. 相似文献

Aerodynamic and diluent effects on the emission of nitrogen oxides from hydrocarbon diffusion flames
Subramanyam R. Gollahalli 《加拿大化工杂志》1978,56(4):510-514
An experimental study of the quantities of oxides of nitrogen produced in hydrocarbon gas jet flames in concentric and cross-flow air streams is presented. It is seen that the structure of flames has a strong influence on the quantities of NO and NO2 generated in diffusion flames. Increases in jet velocity result in the increase of NO and NO2 emitted from flames in concentric air streams. However, air stream velocity has opposite effects on the yields of NO and NO2 from flames in cross-flows. Additions of diluent to jet and air streams decrease NO and NO2 in both concentric and cross-flow air streams. The implications of scaling these results to fullsize flare stack flames have been discussed. 相似文献
