Účinnost kotle při spalování uhlí u kotle s přímým foukáním

Abstract

The bachelor´s thesis deals with the efficiency of a dry bottom boiler equipped with a direct blowing for combustion of black coal, which is a traditional energy source in the Czech Republic. The thesis is structured into three principal sections. The first is the theoretical one, focused on the description of function of combustion equipments and their classification, the description of the process of fuel preparation and its combustion in the existing plant of the Dětmarovice power station. In the second, practical one, there is carried out the stoichiometric calculation for fuel and its consumption and there are determined the ash and air balances. In the last, final section it is performed a comparison of the impact of the content of separate ballast components on partial losses and is compared the resulting calculated value of efficiency of the boiler to the actual one.
