Semenov developed a model that describes the thermal ignition phenomenon quantitatively. Assume that the temperature, , of the reacting system is constant and uniform across the volume of the system and assume that the walls of the system and the ambient external temperature, , are the same. The steady-state temperature is obtained by setting the heat production term (i.e., the left-hand side of the equation) equal to the heat losses term, which is mainly due to convection between the system and the surroundings (i.e., the right-hand side of the equation):
