Hi,
I'm a 4th year chemical engineering undergraduate student. I have a design project this year where I have to design a unit operation in a power plant. I've chosen a waste heat boiler as my unit operation. The waste heat boiler essentially recovers exhaust heat from the flue gases that are produced from the combustion in the furnace. However, there is a problem that I'm facing. The course outline of my university says that a good choice of a unit operation should contain at least two (2) of the following elements:
• Mass transfer
• Heat Transfer
• Reactions
• Particle technology aspects such as settling velocities, or population balance models.
The problem is, the overwhelming part of the design of the waste-heat boiler is in relation heat transfer, while mass transfer is only a very small aspect of it. I need to have a design that has a balance of two elements from the four elements mentioned above. Is there any way around this? Am I wrong about the fact that mass transfer only plays a small part in the design in comparison to the heat transfer?
