Various criteria are taken into account and the final solution is adapted to the conditions of EKOL, spol. s r.o. company. Technical and economical evaluation.

The topic of this thesis is the calculation of the steam-boiler. The begining of the thesis deals with stoichiometric calculations. In the second chapter is performed the heat balance of the boiler. In the fourth and fifth chapter are defined dimensions of the fire and is established the temperature of a combustion gas in the outlet from the fire. The fifth chapter includes the balance calculations of the particular heating surfaces of the steam-boiler. As a conclusion of the calculations of the steam-boiler is performed the total balance. In the last chapter are proposed the methods for a reduction of the quantity of NOx contained in the combustion gas.

The aim of thesis entitled steam turbine is a condensing steam turbine with steam extraction, in twin-shaft implementation for municipal waste-incineration plant. The first part of the work is focused on the design used and the selected concept turbine. The second part is engaged in thermodynamic calculation of backpressure and condensing part. The end is devoted to technical – economic comparison with other possible conceptual variants.

Goal of this dissertation is design of rotary reduction for entered input parameters that it is connected in parallel with reducing station. Further I´m looking into thermodynamic calculation of stage and chosen parts of turbine, making of project design of connection of rotary reduction to steam circulation. Dissertation is concluded by designed cross-section of turbine.

This Master’s thesis deals with a pre-calculation of a steam condensation turbine on a blading mid diameter. The governing stage is solved as a A-turbine wheel, impulse blading. Multistage blading is solved as a reacion stage by ca/u method. Further, detailed calculation of last stage with a twisted blade is made. Thesis contains comparision of obtained results with a results provided by contracting company. Final part of thesis deals with a design of sectional shape of a turbine blade.

The thesis deals with a project of a steam generator heated with liquid sodium. The first section describes some types of steam generators at nuclear power plants which have been projected or put into use. The next part presents a draft concept of the steam generator, solved by this work. The implementation of the steam generator module has been selected from several options, based on the thermal, hydraulic and stress calculations and on the chosen criteria. The conclusion of this thesis deals with the evaluation of the final solution in terms of nuclear safety and technical solutions, and compares this solution to similar projects following various criteria.

An objective of this thesis is to design a grate steam boiler for burning straw. Generated steam will be used for technological purposes or cogeneration. Calculations of the heat comes from engaged temperature and pressure of the overheated steam and characteristics of characteristics of the biomass as well.

This thesis deals with reducing the moisture content of biomass drying and its subsequent use as biofuel. The work is a belt drying and its integration into the system with a grate boiler. It proposes a variety of drying options for use of different drying media. In the end, an economic evaluation of the combustion system uses a belt dryer, and a system without any possibility of drying the fuel before it enters the boiler.

The theme of this master thesis is one body steam turbine of 150MW with reheat. There is calculated heat balance of the system with three low pressure heaters, deaerator and two high pressure heaters. Next part deals with calculation of blades and its lenght. Next are the attachments of blades into stator and rotor parts of the turbine. By the end of the thesis there is recalculation of heat balance scheme and blading followed by calculation of parameters for operation of turbine in 75% and 50% of the rated power output. The output of the whole thesis is drawing of horizontal cut of the turbine.

The purpose of this Diploma Thesis is the construction design of the steam-boiler for the combustion of biomass – wood pellets. For the specified parameters have been defined stoichiometric calculations and calculations enthalpy burnt gas. In sequence, there is designed and solved the configuraion of the steam-boiler, so that the result design and the number of the heat-delivery surfaces can be determined, in dependence on the required inlet parametres of the air and outlet parametresof the water vapour. These parametres mean the amount, the temparature and the pressure. The aim of the thesis is to make a design of the steam.boiler burning biomass according to the set parametres. This very ecological fuel can really substitute the fossil fuel and friendly respect the environment.
