WebThermal runaway describes a process that is accelerated by increased temperature, in turn releasing energy that further increases temperature. Thermal runaway occurs in … WebIn case of problems, reaction runaway may appear due to loss of cooling water in the reactor, over- or miss-charged reactant, external fire, and loss of agitation or wrong reaction temperature in reactor. Such cases are difficult to predict, almost not possible to control, and can lead to explosion.
