Combustion and High Temperature Processes

• Set up mass and energy balances for combustion systems
• Estimate flue gas amount and composition from stoichiometric calculations
• Use simplified and detailed chemical models to estimate combustion rate and formation of pollutant species
• Couple chemical and thermal analyses of reacting systems
• Set up simplified conservation equations for reacting flows
• Explain conceptual and practical differences between premixed and diffusion flames
• Assess the impact of turbulence on combustion rates
• Set up and use simplified model for droplet evaporation and combustion
• Set up and use simplified model for particle heating and pyrolysis
• Set up and use simplified model for char oxidation
• Use the above tools together with numerical solvers to evaluate and optimize industrial high-temperature processes

The course is related to both chemical and mechanical engineering, as both of these types of engineers work with fuels and emissions. Topics covered include thermal conversion of gaseous, liquid and solid fuels (pyrolysis, gasification, combustion). Developed models are applied to practical systems, i.e., gas turbines, motors, pulverized fuel combustors, fixed bed and fluid bed, as well as related industrial high temperature processes. The content of the course is relevant for developing sustainable high temperature processes and this will be illustrated in the course. The different systems are treated theoretically and the students solve larger, practically oriented problems during the course. For non-chemical engineers, introductory material is presented at the start of the course.

28020/41401, Experience with numerical tools for solution of ordinary differential equations such as Matlab, Maple, or similar. In addition it is an advantage with knowledge of chemistry at an introductory level.
