Maskinteknik – Energitekniska laborationer 2

Efter avslutad kurs ska den studerande:
– ha tillägna sig praktisk och fördjupad kunskap om funktion hos och uppbyggnad av maskiner
och processer som behandlats i utbildningens energitekniska kurser.
– ha lärt sig hantera uppstart -drift och övervakningsrutiner samt utvärdera driftparametrar
med avseende å driftsäkerhet, driftsekonomi och miljöpåverkan.

Objectives:
The student gains practical and deeper knowledge about various machinery and processes that have been dealt with in energy engineering modules. The student also learns how to manage start-up, operation, and surveillance routines, as well as evaluating operative parameters with regard to reliability, running economy, and environmental impact.

Passed course will be noted in student´s records, evaluation scale Pass and High Pass, exchange students will be evaluated A-F according to ECTS

Grupparbeten med arbetsledare inom gruppen. Gruppen skall på basen av laborationsförelägg
självständigt förbereda och utföra laborationsuppgifterna och i rapporter sammanställa och redovisa
resultaten av laborationerna. Vid ett seminarietillfälle presenterar varje kursdeltagare en viss
laboration.

Methods:
Group assignments with a student as group manager. The group is to prepare and implement the assignments independently and in compliance with handouts. The laboratory results are to be compiled and accounted for in reports. Each participant will present one laboratory at a seminar.
