Main themes

Origins, nature, and conditioning of fuels. Mass and energy balance laws of combustion. Physical chemistry and chemical kinetics of combustion: reacting schemes and phenomenology of the modes of combustion. Fuel combustion technologies: conception and design of combustion heat transfer equipment.

Aims

To provide the theoretical and practical background in the use of fuels via a physico-chemical approach to combustion and to present the technological aspects relative to fuel combustion.

Evaluation methods

Written, with open books and notes. The grade on the lab report counts for 25% of the overall grade.

Teaching methods

Laboratory: Operation of a domestic natural-gas boiler and analysis of its combustion efficiency.

Content

1.Energetic study of fuels and their use.

Origins and formation of fuels.

Conditioning and specification of fuels. Global mass and energy balance laws in combustion. Control and diagnostic techniques.

 

2. Thermochemistry.

Chemical kinetics of combustion. Chain-branching mechanisms. Explosivity and flammability limits, flame temperature. Chemical reaction rates, deflagrations and detonations. Pollutant formation. Measurement techniques.

 

3. Combustion and heat transfer technologies.

 Combustion of gases: burners for premixed and non-premixed combustion. Combustion of liquids: pulverization and diffusion. Combustion of solids: fixed beds, pulverization, fluidized beds.

 

4. Use of heat: Heat transfer basics. Conduction, free and forced convection, radiation. Applications to combustion related problems.

 

The balance laws of mass and of energy and the physico-chemical calculations are the objects of exercises and laboratory experiments. In these experiments emphasis is placed upon the phenomenology of combustion, control methods and diagnostics and upon operating methods.
