2. Efficiencies and losses of steam generators, energy balance of steam generator
3. Modern boiler types and constructions, performance analysis of SG furnace and second pass
4. Fluidised bed combustion, pulverized fuel combustion, biomass and waste combustion, gas and oil combustion
5. Heat recovery steam generator, supercritical boiler technology, recovery boilers
6. Control and use of steam generators, boiler standards and KLTK safety instructions, start up and down intructions
7. Boiler water treatment, waterside and gas side scaling, deposition and corrosion in steam generators
