Simulation Study on the Safety of a Fully-Enclosed Coke Oven Shed

In recent years, the implementation of coke oven enclosure measures has been initiated to effectively collect and treat fugitive emissions from coke ovens. Currently, primary enclosure solutions mainly include fully-enclosed and semi-enclosed structural configurations. This study focuses on a fully-enclosed coke oven shed designed by a coking plant. By establishing a physical model, the research simulates the diffusion behavior of unburned dispersed raw gas inside the shed under specific conditions: a plant-wide power outage coupled with strong crosswinds, and a failure in the ignition of the vented gas. The simulation results are used to assess the safety of the internal environment within the large enclosure.
