Theoretical and practical knowledge on the technology and knowhow of producing steam. Classification and operational principles of steam boilers, their basic components, the required control and safety devices, calculations for their design, estimation of their efficiency, steam networks. 

Course Description 

Theory: Phase change of water, types of boilers (classification and description), elements of combustion and relevant calculations, fuels, energy balance, efficiency and losses, furnaces, burners (for solid, liquid or gas fuels), basic components of boilers / steam generators (vaporization heater, superheater, reheater, air and water preheaters), devices for monitoring, measurements, control and safety, pumps, fans, auxiliary systems (steam traps, dearetators, steam-water separators), operation, water circulation, load control, heat transfer during phase-change, water treatment, reference to special topics (thermal calculation of basic components, static calculation of a boiler), modern technologies and current research (pollution reduction, modernization of steam plants, etc).

Laboratory: Operational principles and detailed description of a laboratorial steam boiler, measurements during operation, basic and auxiliary devices of the steam boiler and network, safety and control, water treatment procedures, description of operation and management of the plant, measurements during operation, calculation of the boiler efficiency and losses based on steam measurements, estimation of the boiler efficiency based on gas measurements. 

Expected Course Outcome

By the end of the course the students should: 

• Know the basic knowhow and technology of industrial steam generation, the relevant steam boilers their basic components, safety and control devices.
• Be able to estimate (by means of calculations or by measurements) the efficiency of a boiler.
• Recognize the losses of a boiler and their causes.
