Course purpose

The aim of the course is to provide an understanding of and training in thermal design of industrial energy equipment. The level of understanding should be such that the students in their professional role as engineers should be able, individually and in teams, to select and assess energy equipment, and if necessary, to design basic equipment with respect to dimensioning, materials selection, construction and economic performance. Equipment addressed in the course includes steam boilers, heat exchangers, heat pumps and gas turbines with heat recovery. The course aims to be practical and focus is on heuristically derived methods for design. The main learning tool is design projects, which are performed in teams of two students. It also has laboratory exercises performed in larger groups.

Course literature

 

• Design of Industrial Energy Equipment – Course compendium

Distributed during the first lecture, or picked up at the office of the examiner (Magnus Rydén, Division of Energy Technology, 4^th floor in M-building) at some later occasion.

 

• Project exercises and laboratory instructions

Become available for downloading from the course homepage during the course.

 

Course design

The course starts with an introduction to general challenges and design strategies for energy equipment, aiming for good understanding of the trial-and-error concept using heuristic approach for preliminary design. The course then focuses on design projects and exercises, organized as projects conducted by small groups of students. As part of the exercises professional design tools are used or demonstrated. A study visit to a boiler manufacturer is included to reinforce the professional aspect of design work and visualize large components and their production. An industrial size heat pump plant is visited in the framework of a laboratory exercise and an experimental laboratory is performed to shed light on the critical heat transfer mechanisms during boiling.

The course contains the following main parts. i) Boiler design – boiler types, construction, furnace design, radiative heat transfer, convective heat transfer, water circulation, convection section design. ii) Heat exchanger design – main types, construction, heat transfer and pressure drop theory for tube-and-shell and plate heat exchangers, tube-and-shell and plate heat exchanger design, professional design software. iii) Heat pump design – types, selection theory, cycle design, boiling and condensation heat transfer theory in particular for shell and tube heat exchangers, refrigerant properties and selection, professional design software. iv) Industrial gas turbines – gas turbine types, heat recovery steam generator (HRSG), construction and design, supplementary firing, gas turbine selection theory, assessment of economic performance of combined heat and power (CHP) designs.

 

Lectures

The course has 11 conventional lectures. Handouts will be uploaded on the course homepage on the course home 24 hours before the lecture, at the latest. Lectures and lecture handouts should be treated as course material and can be subject to examination.

Project exercises and schedule

The course has 5 project exercises. Students are asked to form groups of two by using tools made available on the course homepage. There are 36 h of scheduled time for consultation with supervisors, but students may need to perform additional work on their own. The problem formulation, with individual input data, will be available for download or handed out at the start of the session, at the latest. The first scheduled sessions for each project includes an introduction by the supervisors. One report is written by each group for each project and they shall be submitted via the course homepage. The report shall include a Word- or pdf-document, as well as solutions e.g. MATLAB-code or ASPEN-files. Respect the due dates. Missed deadlines results in that reports are placed last in line for review, resulting in slow feedback. Repeated missing of deadlines may result in significant delays in approval and ultimately failure to pass the course moment in question.

Laboratory exercises

Industrial laboratory exercise at the heat pump plant Ryaverket, owned and operated by Göteborg Energi AB. The purpose is to perform calculations on a real industrial processes and to give an overview of factors such as dimensions and layout of large industrial heat pumps. The students in each session will be divided into three groups, with 3-4 students each. 4 hours will be scheduled and report must be submitted by each group. The following 4 sessions are available: on Tuesday, 25/2 from 8:00-11:45 (1^st session) and 13-17 (2^nd session) and on Wednesday, 26/2 from 8-12 (3^rd session) and 12:45-16:30 (4^th session). Sign up to suitable session on the course homepage.

Experimental laboratory exercise in boiling. The purpose is to demonstrate the critical nature of heat transfer due to boiling in the design of energy equipment. The lab is performed in the chemistry building and takes approximately 2 h. Meeting point is the halls of large equipment, floor 1 in the Chemistry building. The following 8 sessions will be available: on Tuesday, 3/3 from 13-15 (1^st session) and 15-17 (2^nd session), on Wednesday, 4/3 from 13-15 (3^rd session) and 15-17 (4^th session), on Friday, 6/3 from 8-10 (5^th session) and 10-12 (6^th session), and on Tuesday, 10/3 from 13-15 (7^th session) and 15-17 (8^th session). Sign up to suitable session on the course homepage.

Both laboratory exercises are mandatory and approved reports are required to pass the course. Failure to participate will be handled individually for each case, taking the reason behind non-participation into consideration.

 

Other activities

Study visit to Valmet Power AB. The purpose is to provide an overview of scale and activates involved in designing and manufacturing components such as boilers and evaporators, as well as insights into the world of the process engineer. TIME WILL BE ANNOUNCED LATER, BECAUSE VALMET IS CURRENTLY RELOCATING PARTS OF THEIR WORKSHOP.

 

Communication between teachers and students

Use ordinary e-mail when contacting the teachers, or drop by their respective office (Division of Energy Technology, 4^th floor, M-building). The supervisors are not obliged to support students outside of scheduled time, but will usually do their best to assist. Please respect that they have other duties to attend to, in addition to teaching. So try to keep as much communication as possible during scheduled time, of which there is plenty in this course.
