Abstract
This master thesis is written at the division of Industrial Electrical Engineering and Automation (IEA) Lund University, Faculty of Engineering, in
cooperation with AB Regin in Landskrona.
AB Regin wishes to determine whether their existing controller platforms
can be used to implement a control system for boilers. The control system
should be flexible in terms of boiler size, boiler fuel and boiler type.
The main aspects associated with the combustion process are reviewed, and
different types of fuel commonly used in boilers are investigated and compared.
The most common boiler designs are described, and definitions used
in boiler context are explained.
To establish what techniques have been developed to improve boiler efficiency... (More)
This master thesis is written at the division of Industrial Electrical Engineering and Automation (IEA) Lund University, Faculty of Engineering, in
cooperation with AB Regin in Landskrona.
AB Regin wishes to determine whether their existing controller platforms
can be used to implement a control system for boilers. The control system
should be flexible in terms of boiler size, boiler fuel and boiler type.
The main aspects associated with the combustion process are reviewed, and
different types of fuel commonly used in boilers are investigated and compared.
The most common boiler designs are described, and definitions used
in boiler context are explained.
To establish what techniques have been developed to improve boiler efficiency
an empirical study is performed. The different techniques are discussed
in detail, involving both control systems and design changes. Finally
the measurement instruments involved in these improvement techniques are
described.
Case studies are performed to find out which techniques are used in practice
to improve efficiency of boiler systems. To get a good idea of common techniques,the cases include establishments that use different fuels, and range
from small scale to large scale.
An effort is made to implement a boiler controller on the EXOcompact platform
from AB Regin. A control algorithm is outlined and implemented for a
fictional system. The system is then simulated using a demo kit from Regin.
Some tests are performed to verify that the function of the control system is
acceptable, and the results are discussed.
Finally the overall thesis is discussed, and issues that should be addressed
in future development are listed and explained. (Less)
