Fluidized bed fundamentals


Chalmers


The course describes the principles of fluidization and related phenomena (i.e. mass and heat transfer, fluidization regimes, fuel conversion, in fluidized bed units). It also treats the main present applications and emerging technologies based on fluidization engineering and, particularly, those related to the conversion of solid fuels (including process elements). Selected problems related to the design and operation of fluidized bed units for conversion of solid fuels are formulated and solutions are indicated.

The content of the chapters to be treated is assumed to be known by the participants in advance (homework). Lecture notes will be available before each lecture at a Box file server area (link will be given to participants before the course start).

There will be an exercise (in the form of home work) presented in beginning of May.


After completion of the course the student should be able to:

-    Describe the principles of fluidization and the roles and interactions between different underlying phenomena (i.e. mass and heat transfer, fuel conversion)

-    Describe the main applications based on fluidization engineering and, more in detail, those related to conversion of solid fuels (including process elements)

-    Describe the background and principles of emerging fluidized bed technologies

-    Identify the main challenges of different fluidized bed applications and formulate appropriate actions

-    Formulate and solve problems related to the design and operation of fluidized bed units for conversion of solid fuels


The lectures (2 hours+1 hour in reserve to allow extension if necessary) will treat topics from the book, by extending or discussing the material.

All lectures will take place at:

Lecture room WIND
M-building, 4th floor, Campus Johanneberg, Chalmers
Hörsalsvägen 7a, 41296 Göteborg
