Pressures and temperatures of steam in a Clausius-Rankine cycle for raising work are progressing due to the development of stronger creep resistant materials. So the efficiency of raising electricity becomes higher which reduces costs and saves the environment. Heat recovery boilers in connection with advanced gasturbines offer a further efficiency gain at the cost of fuel flexibility. Calculations of the amount of combustion air and flue gases, the heat content and the gas velocity offer the basis for the design. Very accurate calculation of the required surface for heattransfer by radiation and convection is nescessary for modern boilers. Heat release in the furnace and the residence time is defining the production of harmful emissions in the environment. Special attention is given to boiling phenomena, water steam mixture flow and stability, feedwater properties and corrosion. Types of boilers and their control characteristics are discussed. Similarities and differences with nuclear boilers are emphasised.

Students not studying in the subject group Proces and Energy have to contact the lecturer.

Applying relevant subjects from many other courses on hydrodynamics, heat and masstransfer and strenght of materials to get understanding of the operation and the design problems of complicated apparatus in energy conversion.

No use of computers during the course. It mihgt be the case in related projects.

Laboratory project(s):

Thinking about how to establish the main dimensions of energy conversion equipment in connection to the proces parameters.
