In this course students will acquire necessary knowledge and skills for designing, maintenance and operation of industrial furnaces, and basic skills required for the maintenance and operation of industrial boilers. Additionally, students will learn about methodology on energy balances and the basic principles of efficient use of energy in industrial furnaces and boilers.

Students will gain necessary skills to work on design and the organization of maintenance in industrial furnaces, and the planning of maintenance and operation of industrial boilers. Students will be trained for work on the projects for energy efficiency in industrial furnaces and boilers.

1. Basics of combustion theory (solid, liquid and gaseous fuels). 2. Basics of heat radiation. 3. Definition and classification of industrial furnaces and boilers. 4. Elements of construction and equipment of industrial furnaces. 5. Energy balances of industrial furnaces. 6. Characteristics and specification of industrial furnaces construction (furnaces for heating and melting of metals, nonmetals industrial furnaces, ovens in the food industry, etc). 7. Application and specification of industrial boilers construction . 8. Characteristics of steam and hot water industrial boilers, boiler outlines, overview of the boilers construction, boiler furnaces and reheating surfaces, energy balance and definition of coefficient of efficiency, procedures for boiler testing.

1. Examples of selected types of industrial furnaces. 2. The elements of construction and equipment of industrial furnaces. 3. Examples of material and energy balances in combustion of gaseous, liquid and solid fuels. 4. Examples of heat radiation regarding calculation of heat transfer within kiln and boiler furnaces. 5. Examples of material and energy balances of industrial furnaces. 6. Examples of energy balances of industrial boilers. 7. Calculation problems: Preparation and assignment of calculation problems; students will solve problems in classes with help of teaching assistant. 8. Description and preparation of laboratory exercises: measurement instruments and methodology, study the structure, organization of work on laboratory exercises. 9. Laboratory: measurement of energy losses in industrial furnaces in real operation: Students divided in groups will measure the parameters necessary for the calculation of energy losses in industrial furnaces in a selected company.
