ANALYSIS OF DETERMINING THE LIMITING CONDITIONS FOR THE OCCURRENCE OF THE GORENJE PROCESS IN BUILDINGS AND STRUCTURES

This article analyzes the determination of the limiting conditions of
the gorenje process in buildings and structures. All combustible substances contain
carbon and hydrogen– which are the main components of the gas-air mixture
involved in the gorenje reaction. The ignition temperature of combustible substances
and materials is different and does not exceed 300°C for most. The analysis showed
that the process of fire occurrence should be taken into account in cases where the
possibility of spontaneous ignition or spontaneous combustion is being investigated.
The latter can sometimes occur due to prolonged exposure to heat at a relatively low
temperature and cause fires. Ignition is the process of spreading a flame through a
gas-air mixture. At the rate of the outflow of combustible vapors and gases from the
surface of the substance equal to the speed of flame propagation through them, a
steady flame gorenje is observed. If the flame velocity is greater than the velocity of
vapors and gases, then the combustion of the gas-vapor mixture and selfextinguishing
of the flame occurs. Ignition sources are a necessary condition for
ignition of a combustible mixture. Ignition sources are divided into open fire, heat of
heating elements and appliances, electrical energy, energy of mechanical sparks,
static electricity and lightning discharges, energy of self-heating processes of
substances and materials (spontaneous combustion), etc. Special attention should
be paid to the identification of ignition sources available in production. Finding out the
conditions in which the gorenje process took place during the fire, especially before it
was detected, is directly related to determining the period of the fire's onset, and
therefore to the study of certain versions about the cause of its occurrence
