Abstract

Carbon deposition on wall is usually encountered in the operation of coke oven and may lead to serious operational problems in the coking process. The removal of carbon deposition in coke oven is considered by using the air injecting burn-off method. A three-dimensional, transient, turbulent reacting flow simulation is conducted with CFD method in the study. It is found that extra air would be sucked into the oven from the atmosphere through the opened charging holes to facilitate the burning off process. The quasi-periodic flow motion takes place in the coke oven is stemmed from the interactions between natural ventilation and combustion reactions occurred inside of oven. This breathing-like flow motion introduces additional air into the coke oven and facilitates the burning-off process of carbon deposits.
