Estimation of parameters for endogenous hotspot emergence during coal cargo transportation by bulk carriers

The article briefly describes the fire and explosion properties of coal raw materials (hard different grades). relevance problem is shown on example incidents occurring during transportation by modes transport. issues bulk are considered in more detail. paper aims at determining kinetic parameters low-temperature oxidation processes leading to self-heating and/or spontaneous combustion coal, optimal forms combustion. On basis data obtained, it suggested use cargo holds with strictly defined geometric characteristics. methodological approach Prof. J.S. Kiselev method synchronous thermal analysis were chosen as main research. proposed based application a dry-air thermostat. It permits study dependence occurrence mass thermal-physical ambient obtaining curves heating cooling rates. applied authors made possible prove need for careful control fine fractions. Thus, have established rate oxidative thermochemical pyrolysis fractional composition sample applying highly scientific method. As result experimental studies, calculated autoignition, namely, activation energy preexponential multiplier. They characteristics shape accumulation bulkhead hold that would minimise probability within accumulation.
