A condition for the award of credit in the subject Technical Thermodynamics is regular attendance in the classes and obtaining a minimum of 50 points in each test.
Passing the examination, which is both written and oral, is a condition for successful completion of the course.
Aims
Complete overview about the importance of heat techniques in decisive technological processes of building materials production, especially of production economy and ecological aspects. Basic outlook in national and worldwide balance of energetic resources, mastery of heat balances and of tasks connected wit heat savings solution especially in energetically most demanding processes of drying and burning, environmental responsibility improvement of building materials manufacturers to produce sustain ecologically acceptable products.
The student will gain knowledge about the importance of thermal technology in the crucial technological processes of production of building materials, both in terms of process quality and production, and especially the economics of production and ecological aspects. The student will gain a basic orientation in the national and global balance of energy resources. Strengthen the awareness of the ecological responsibility of manufacturers of construction materials as sustainable environmentally sound products.
