Ever heard of Fire Spray NSW? There are different ways through which self-sustaining cycle of combustion could be interrupted. Irrespective of the method to be used, the final goal is basically to reduce rate of transfer of heat to polymer and thereby remove the supply of fuel.
In all there’re 4 processes involved with flammability-decomposition, preheating, combustion and ignition. Preheating includes heating of material through external source that helps in raising the temperature of materials at the rate which depends on thermal intensity of the source of ignition, thermal conductivity of material, specific heat of materials and latent fusion of heat and vaporisation of material. Once heated sufficiently, the material starts degrading that are loses its actual properties as weakest bonds start breaking down.
The gaseous combustion products
The gaseous products of combustion are produced, and the rate depends on the factors like temperature needed for the purpose of decomposition, the external heat and the decomposition rate. Concentration of the flammable gases increases subsequently till it reaches the level which allows sustained oxidation in presence of the source of ignition. The characteristics of ignition of the gases as well as oxygen available are 2 most important variables in the process of ignition and these characteristics are quite prevalent in such a scenario.
After the ignition as well as removal of the source of ignition, combustion primarily become self-propagating when sufficient heat production happens and its radiated back to materials for continuing the process of decomposition.
