Course detail

Boilers

FSI-LKAcad. year: 2018/2019

The course is concerned with detailed calculations of the combustion chamber and convection parts of the boiler and with the basics of the hydrodynamic and aerodynamic calculations. Conception problems in the design of various types of boilers for solid (incl. biomass), liquid and gaseous types of fuel, wastes and fuel mixtures will also be presented. Also dealt with are: construction and calculations of the boiler heat exchangers, application of special construction materials, and new trends in the construction of boilers.

Learning outcomes of the course unit

Student will acquire theoretical knowledge, which they can apply as well prepared specialist to construction of boilers and their operation. At seminars students will get practical experience with calculations needed for their work in power engineering.
