Combustion Devices and Heat Exchangers
FSI-LSZAcad. year: 2018/2019
The subject contains two parts. In the first part we will get acquainted with the basic types of heat exchangers (regenerative, regenerative, mixing). Students will learn the basic principles of designing heat exchangers. In the second part the students will be acquainted with the operating characteristics of steam and hot water boilers. The properties of fuels and their impacts on the boiler are presented. Further statics and dynamics of combustion, boiler thermal balances and individual types of boilers according to used fuel.
Learning outcomes of the course unit
Student will be able to apply theoretical information mainly from thermo mechanics, hydromechanics and heat and mass transfer to combustion devices and heat exchangers. Lectures are accompanied by seminars where specific technical problems will be solved.
Thermomechanics, heat and mass transfer.

Language of instruction
Learning outcomes of the course unit The aim is to acquaint students with the current state and theoretical design of boilers and heat exchangers and with the modern directions of development of these devices. Upon completion of this course the student should be aware of the types and properties of fuels and their impact on the design of the boiler and will be able to the basic thermal calculation necessary for the design of the boiler and the heat exchanger.
