Combustion technologies

  Oil flame WSA Coal flame during the start of a steam generator

The students gain insight into the modern combustion technologies for gaseous, liquid and solid fuels for boilers and furnaces. After a short reprise and particular enhancements of the basics of combustion (balance equations, chemical equilibrium, reaction kinetics) and of heat and mass transfer these topics are applied to steady combustion of common fossil fuels such as gas, oil and coal in technical systems. It is discussed how much oxygen is needed for a complete burnout of a specific fuel. Furthermore the adiabatic temperature is defined and calculated. Besides the different phases of a combustion the possible losses and production of pollutants are identified and explained. An overview is given on common methods of industrial design. At the end actually build furnaces and power plants are presented and the pros and cons are discussed.

After the successful participation, the students know the methods the operating mode as well as the methods to design boilers and furnaces. They are able to do independent calculations to design the above mentioned apparatus.
