Thermal analysis of chlorine-containing substances obtained from C13-C14 n-paraffins (chlorine content is 8-75 wt%) and olygoolefines with MM ≈ 104 (to 30 wt% Cl) is made. It is found that the kinetics and mechanism of the substances' gasification depend on their chlorine content and the nature of the original hydrocarbon. A method for the evaluation of flammability parameters of the substances used as flame retardants is developed. The increase of the limiting oxygen index of the substances with increasing chlorine content and hydrocarbon chain length may be described in accordance with the heat model as a result of the inert dilution of the gaseous fuel by the incombustible component. However, in addition to the change in the stoichiometric combustion coefficient, the additional heat losses related to the formation, evaporation and also the heating of HCl to flame temperature must be taken into account. It is found that the additional heat losses are equal to about 2.5 kJ per chlorine mass fraction. |
