• Thermal Power Engineering, Semester 2, position 1

Reaching the competence and academic skills and methods for it's acquiring. Developing creative capabilities and mastering the specific practical skills. Goals determine the specific results which should be achieved within the subject. Goals also represent basis for control of the achieved results. Activities in this subject are in accordance with basic tasks and goals of the study program.

After successfully completing the course, the students will be able to: • Perform the thermal boiler calculation. • Calculate the heat balance of the mill drying process and chose the type and size of the mill. • Perform the air and flue gases aerodynamic calculations of the steam boiler and choose an appropriate fan. • Perform the strength calculation of basic elements of a steam boiler. • Acquire the process of corrosion and wear of heating surfaces, as well as their protection.

Thermal calculation of the steam boiler heating surfaces - calculation of furnace, calculation of half-radiation and convection heating surfaces; Mill processes (coal dust characteristics, heat and material balance of mill drying process, mill control diagram); Aerodynamic of the air and flue gas tract (balanced draft boiler, forced draft boiler and natural draft boiler); Hydrodynamics of steam boiler (hydrodynamics of water heater, evaporator and superheater); Steam boiler strength calculation; Corrosion, wear, defilement and cleaning of steam boiler elements.

Auditory exercises consist of demonstration exercises (Classification and construction of steam boilers with appropriate heating surfaces, auxiliary devices and equipment); Guidelines for preparation of the project - Based on information (obtained and calculated) in the project from subject Steam boiler elements and equipment, it is necessary to develop thermal calculations for given industrial steam boiler. In this project it is necessary to perform thermal calculation and dimensioning of the following heating surface - furnace (radiation evaporator), convective evaporator, steam superheaters, water and air heaters. After dimensioning the steam boiler heating surfaces, it's necessary to make the steam boiler drawing in three sections.

Necessary condition: Bachelor's degree; Preferred passed exam: Steam boilers elements and equipments
