Description of learning outcomes

Basic concepts: environment fire, oxidation, combustion, fuel. Initiators of combustion, types of initiators. Laminar and turbulent combustion. Example description of laminar combustion (eg burning candles), issues related to lighting of the flame and its emissivity. Ways to initiate combustion of combustible materials – piloted ignition, ignition (autoignition), spontaneous combustion. Exposures heat produced during combustion in the fire environment. Types of combustion., mechanisms of initiation of combustion of flammable substances. The combustion of solid materials - burning plastic, wood and wood-based materials. Stability and reactivity of solid materials, their kinetic and thermodynamic properties. Thermal loads resulting from the combustion of solid materials. The smoke rate and toxicity of combustion products. The differences between homogeneous and heterogeneous combustion (oxygen) of solids. The combustion of combustible dust and their susceptibilit to ignition and explosion (burning particulate organic and inorganic).
