17498 - Mechanical Systems

Learning outcomes

The course has the aim to furnish the general criteria and the corresponding mathematical methods of technical and economic design of those mechanical plants, which are auxiliary systems necessary to the production processes of industry and services. The module allows the student to analyse the design principles of mechanical plants, defining the methodologies for their proper economic and technical selection .  The course describes the design criteria (schemes, equations and rules) both on the technical point of view and on the economic one.

Course contents

Mechanical plants characterization. Technical-economical optimisation methods; examples and applications.

Combined plants for production of heat and electric power.  

Industrial steam production and distribution: steam generator operation, steam distribution networks, recovery and drain systems. Compressed air production and distribution: compressor system design, condensate drain systems, air network distribution.
