Course purpose

The aim is to introduce the student to thermochemical conversion processes in applications important for industrial processes in todays and tomorrows society. The course covers processes like pyrolysis, gasification, cracking and combustion where the conversion aims to produce material, heat, electricity or steam. The understanding of those processes is of great importance today and a key competence in the transformation towards a future resource efficient production, waste handling and recycling.

 

Structure

The course consists of two parts: the first, Conversion science, is related to the conversion process itself while the second, Conversion devices, is related to its applications.

Conversion science represents the main part of the course, since it is fundamental for the general understanding of the design and operation of the various devices existing. In first place, basic knowledge is given on chemistry, physics and the various fuels. This is used thereafter in the teaching of phenomena such as criteria for combustion, combustion of various fuels and generation and destruction of emissions.

Conversion devices acquaint the student with the most common techniques and designs in use today for combustion and give an overview of emerging technologies. The knowledge acquired is applied in alignment with the lectures through the calculation by students of the design of a boiler and the application of the design principles onto an emerging conversion technology.
