Abstract To thoroughly study the extinguishing effect of a high-pressure water mist fire extinguishing system when a transformer fire occurs, a 3D experimental model of a transformer is established in this work by employing Fire Dynamics Simulator (FDS) software. More specifically, by setting different parameters, the process of the high-pressure water mist fire extinguishing system with the presence of both diverse ambient temperatures and water mist sprinkler laying conditions is simulated. In addition, the fire extinguishing effect of the employed high-pressure water mist system with the implementation of different strategies is systematically analyzed. The extracted results show that a fire source… More > Graphic Abstract

Abstract In the production (as co-fuel or alone) of solid refuse fuel (SRF), knowledge about the characteristics of the raw materials is required for an ecofriendly and effective combustion process. SRFs are commonly produced by drying combustible waste and removing incombustible matter, resulting in a higher combustibility as compared to the original waste. However, the characteristics of SRFs may highly vary depending on where and from which materials they were produced. Thus, we investigated the characteristics of various SRFs using thermogravimetric analysis (TGA). As a TGA sample is commonly small, on the scale of milligrams, and, unlike homogeneous fuels, SRFs are… More >
