    Tepelné samovznietenie ako najčastejšie sa vyskytujúce fyzikálno-chemické samovznietenie
    (University of Žilina, 2023) Coneva, Iveta
    Self-ignition and self-heating are processes when the heat required for ignition of a substance arises in the substance itself as a result of chemical, physical or biological processes. The term autoignition should be nderstood not only as self-ignition, the ignition of a substance but as a complex, spontaneously occurring process, from the first moment of temperature rise (self-heating temperature) to reaching autoignition temperature, as a result of chemical, physical or biological processes. The result of the self-ignition process is the ignition and subsequent burning of the substance or material in a flameless or flameless manner (smouldering, incandescence). Thermal spontaneous combustion is among the most common cases of physicochemical spontaneous combustion. Thermal autoignition is a thermooxidation process that is anifested by burning (flame or flameless) after previous self-heating of substances that are heated to a temperature at which the released heat of reaction exceeds the amount and speed of heat removed to the environment.

    Výbušnosť prachov a prašných zmesí – zvyšovanie úrovne vzdelávania odborníkov v bezpečnostných vedách
    (University of Žilina, 2024) Coneva, Iveta
    It is essential to continually enhance the education of students and professionals in the field of safety science by incorporating modern technologies, particularly with a focus on rescue services study programs. In various economic sectors (e.g., industry, agriculture, transport, and others), dust often occurs as an input raw material, intermediate product, final product, usable byproduct, or waste. Combustible dust poses a potential fire and explosion hazard in production and processing technologies and equipment. Safety experts must be equipped to assess the flammability and explosibility of dust in specific technologies and devices, drawing on their knowledge of this critical issue.
