Course detail

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.
