MJ2420 Combustion Theory 6.0 credits

The aim of the course is in-depth knowledge in combustion. The course includes analytical methods for evaluation of applications with combustion i.e. knowledge of how theories and analytical models can be applied for evaluation of real technical components such as boilers, furnaces, combustion engines and combustion turbines. Theories that are treated deal with mass transfer, chemical equilibrium, chemical kinetics and flame technical properties from basic combustion theories to simplified models for combustion of gases, liquids and solids. Applications are examined through detailed analysis of combustion concepts adapted to practical combustion devices.

After completing the course with a passing grade the student should be able to:

ILO 1: Formulate theories, definitions and concepts for combustion and carry out a theoretical evaluation of combustion performance

ILO2: Apply theoretical models for performance calculations adapted to units such as boilers, furnaces, combustion engines and combustion turbines

ILO3: Evaluate and design appropriate combustion-technical solutions for real problems by applying analytical methods and present written solution proposals

Lectures are divided into three modules.

Module 1 (9 subareas and 13 lectures): Basic theories of combustion and calculations related to basic/simplified situations. Subareas that are included by this module are; basic combustion, reactions, chemical equilibrium, chemical kinetics, mass transfer, combustion in laminar and turbulent flames, the bases of liquid and fuel combustion.

Module 2 (4 lectures): focus on practical designs and operating conditions for combustion in combustion devices such as furnaces, boilers, combustion turbines and engines. Strong emphasis is placed on forming of pollution, technologies to prevent emissions as well as cleaning methods related to these applications. Invited visiting lecturers contribute with expertise from world-leading sectors in the combustion area.

Module 3 (2 lectures) introduces development and research related to combustion. Here is included e g catalytic combustion (CatCom) and high temperature combustion (HiTAC), but this will be updated as the development progresses.

Laboratory exercise

Here, measurements on combustion are carried out with laminar and turbulent flames, to characterise the flame and its stability. The work should be documented in a laboratory report that is made in groups. The report should contain a clear description of the laboratory activities, its intended learning outcomes, analysis of results and conclusions. Participation in the lab and submission of the report are compulsory.

The courses MJ1112 Applied thermodynamics and MJ1401 Heat Transfer, or the equivalent

Knowledge of thermal processes for electricity production is recommended, e g via the courses such as Sustainable Power Generation (MJ2405) and Applied Heat and Power Technology (MJ 2426).

If the course is discontinued, students may request to be examined during the following two academic years.

• INLA - Hand in assignment, 1.0 credits, grading scale: P, F
• INLB - Hand in assignment, 1.0 credits, grading scale: P, F
• LABA - Laboratory work, 1.0 credits, grading scale: P, F
• TENA - Written exam, 3.0 credits, grading scale: A, B, C, D, E, FX, F

Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.

The examiner may apply another examination format when re-examining individual students.

Passed all items (INLA, INLB, LABA, TENA) included in the course. The final grade for the whole course is decided by the examination grade TENA (A-F)

• All members of a group are responsible for the group's work.
• In any assessment, every student shall honestly disclose any help received and sources used.
• In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.

Further information about the course can be found on the Course web at the link below. Information on the Course web will later be moved to this site.

In case that too few students sign up for this course, the course will be given to those registered in reduced form, mainly as selfstudies with supporting help.
