Abstract
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%.
