“…CFD methods are especially well suited for understanding deflagration development and propagation inside equipment or through complex structures [12]. To calibrate these models, a frequent practice is to first perform CFD simulations of dust dispersion and explosion experiments in the standardized apparatus: the Hartmann tube [44,45], the 20L Siwek sphere [46][47][48], or the 1m 3 ISO vessel [49]. These models can reduce the time consuming labor and expensive costs of experimental testing.…”

At present, processing and recycling of municipal solid waste (MSW) has become more relevant in our country and the world at large. This problem concerns large towns and cities, where every year millions of tons of all kinds of fractions of household waste are produced. Disposal or recycling of solid waste is an environmental issue, but it is associated with the solution of complex technical, energy and economic challenges. The purpose of this study is to identify the advantages and disadvantages of modern methods of processing and disposal of MSW with the prospect of developing and creating a device for recycling MSW taking into account modern approaches to energy saving and environmental protection. The main results of the study are to create a simple, reliable and technically sound method of MSW disposal to obtain additional energy. The significance of the results obtained for the construction industry is the design of a device for the disposal of solid waste with the production of solid combustion products and further their use as building materials and products for various purposes. Because of the technological process of MSW processing, it becomes possible to generate some returns through use of resulting thermal energy for electricity production.

“…Taveau (2017) reported that large-scale testing required verifying explosion isolation systems and needed to place the explosion isolation device in the correct position [35]. Partial inerting decreases the oxygen concentration in the atmosphere, rather than the complete removal of oxygen, thereby reducing both the ignition sensitivity and the combustion rate of the dust cloud, as well as substantially increasing the minimum ignition energy (MIE) [36]. Several studies have been conducted experimentally on the effect of oxygen content of MIE on various types of dust.…”

Despite recent extensive research and technical development to prevent and mitigate dust explosions, processes that produce and handle combustible materials in the form of powders and dusts, either as a main product or as an undesired by-product, have become a constant dust explosion threat as they become more sophisticated and complicated. This study analyzed the characteristics of 53 dust explosions that occurred in South Korea over the last 30 years, and investigated the differences of dust explosions that happened in various countries, such as Japan, the United States, the United Kingdom, and France. In addition, case studies showed the severity of dust explosions occurring in South Korea. Through the special focus on the three most recent years of dust explosions, the causes and processes of the accidents were identified. Analyses of dust explosions in South Korea show that they were mainly caused by organic matter and metal, and, unfortunately, dust explosions occurred repeatedly during grinding, mixing, and injection of powder materials into facilities. No reported accidents occurred during the production processes of wood or paper during the last three years. Taking these characteristics into account, effective ways to prevent or mitigate dust explosions at workplaces where many dust explosions occurred were suggested.
