In industrial sites that discharge pollutants into the atmosphere, dust collection facilities are generally installed to prevent environmental pollution. Although the dust collection equipment greatly contributes to the prevention of environmental pollution, the painted sludge adhering to the inside of the duct leading to the dust collector is very vulnerable to fire. It is a device that collects polluting gases generated in the work process, and is connected to the duct, and has a structure in which sludge is inevitably stuck in the process of collecting the polluting gas inside the duct. It acts as a combustible material among the three elements of combustion conditions, and when an ignition source acts due to the working environment, it causes explosive combustion and has a structural environment in which combustion can only proceed to the dust collector connected to the outside. In this study, it can be seen that the coating sludge has sufficient energy as a combustible material through the physical property analysis and fire reproduction test, and that the sparks generated from the duct repair tools and cleaning tools are sufficient as an ignition source. Therefore, based on the results of this study, I would like to suggest methods for the removal of combustibles (painting sludge) and the removal of ignition sources (work tool spark) among the three elements of combustion to prevent fires inside industrial dust collector ducts in advance.
