Aims

Expert Knowledge: The First and Second Laws of Thermodynamics. Properties of an ideal gas. States of steam and the use of steam in the production of building materials, steam diagrams; states of humid air, its use in drying in building materials production technology, humid air diagrams. Knowledge of drying in various types of dryers. Principles of calculating heat balances for dryers and furnaces. Students will gain knowledge of the importance of thermal engineering in key technological processes for the production of building materials, both in terms of process and production quality, and particularly in terms of production economics and environmental aspects. They will gain a basic understanding of the national and global balance of energy resources. They will strengthen their awareness of the environmental responsibility of manufacturers of building materials as products that are sustainable from an environmental perspective.

Technical Skills: Students will be able to solve basic problems involving both ideal and real gases. They will be able to calculate changes in the state of steam and air during various characteristic processes and determine their energy requirements.

Professional Competencies: Students will be able to apply the first and second laws of thermodynamics in calculations of heat and work for all characteristic processes of an ideal gas. They can use the h-x diagram for water vapor. They can explain and use the h-x diagram for humid air. They can determine the heat and material balances of theoretical and actual dryers. They can describe various types of drying and dryers, characterize their advantages and disadvantages in terms of thermal energy consumption. They can calculate the heat and material balances of a tunnel kiln.
