Learning outcomes of the course unit

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.

The graduate of the course is able to:
Utilize the first and second laws of thermodynamics in calculations of heat and work for all characteristic processes of an ideal gas.
Explain and apply the i-x diagram of water vapor.
Explain and apply the i-x diagram of moist air.
Determine the heat and material balance of a theoretical and actual dryer.
Describe the different types of drying and dryers, characterize their advantages and disadvantages in terms of thermal energy consumption.
Determine the heat and material balance of a tunnel kiln.
