KIELAR, J. Develop a Proposed Solution for Cleaning of Heat Transfer Surfaces in Boilers for Combustion of Biomass: Bachelor Thesis. Ostrava: VŠB – Technical University of Ostrava, Faculty of Mechanical Engineering, Department of Energy, 2014, 43 p. Thesis head: doc. Dr. Ing. Bohumír Čech.

The Bachelor Thesis deals with the formation (creation) of deposits on heat transfer surfaces of boilers burning biomass, it deals with options to prevent their occurence and options of their removal. In the introduction there are reasons why it is necessary to remove deposits from heat transfer surfaces and what are the benefits of using biomass for production of heat and electricity. In the Czech Republic, the biomass is usually burned in boilers for fossil fuels. Because of the different characteristics of ash from biomass and ash from fossil fuels it is necessary to choose a different method of deposit removal, or subsidize fuel substances increasing the softening point of the ash. The best solution appears to be a combination of the wash in the combustion chamber, a ball like rain on additional areas and subsidizing with substances increasing the softening temperature of the ash.
