This diploma thesis deals with proposal of the steam boiler on combustion uncontaminated wood. For the specified parameters have been implemented stoichiometric calculations and calculations enthalpy burnt gas. In the next part have been dealt with heat balance of the boiler, the efficiency of the boiler, design of the combustion chamber and calculation of particular rating surfaces. The output parametres are temperature, pressure and the amount of steam.

This thesis deals with the calculation of the boiler on stillage. Nowadays, when there's fossil fuels are just biomass seems adequate compensation. The great advantage of biomass boilers is a small amount of emissions, especially the greenhouse gas CO2. Of a given fuel composition is made thermal calculation and dimensioning of heat transfer surfaces of steam boilers. The resulting calculation must follow the parameters of steam at the outlet from the boiler.

The aim of the work is to design a plain wood combustion boiler of 60 t/h output. Fuelling component analysis has been added to the basic boiler parameters. Stechiometric calculations were performed for given fuel composition. Thermal efficiency was set after making thermal balance. Separate convective areas and boiler proportions were designed together with separate steam output parameters (temperature, pressure, amount). Design documentation was added.

This thesis deals with the change of the fuel base of a coal boiler due to the reduction of CO2 emissions and its thermal recalculation. In the first part, there is implemented calculation of the combusting chamber. This is followed by the recalculation of the heat transfer surfaces. The emphasis is placed on the preservation of the exsiting steam parametrs.

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.

This thesis deals with a project of steam boiler to combustion of refused-derived fuel. With respect of required fuel and output parameters of the steam was worked out stoichiometry, energy loss and boiler efficiency, heat flows was allocate to individual heat exchange surfaces. The heat exchange surfaces was calculate and project in detail.

This Thesis deals with thermal control calculation of the existing John Thomson steam boilers burning heating mazut and subsequent thermal conversion to natural gas. The main parts of the calculation are as follows: stoichiometry, thermal balance, conversion of the combustion chamber and heating area.

The thesis deals with the design of a grate steam boiler which has natural circulation and is determined for combustion of wood chips. The boiler has a capacity of 45 t/h and produces superheated steam with the output parameters of 3,5 MPa and 450 °C at the 125 °C feed water temperature. Stoichiometric calculations and the flue gases enthalpy calculations are based on the composition of the specified fuel. The efficiency and fuel consumption of the boiler is also determined. The thesis mainly focuses on the thermal calculation and geometric design of the individual heat transfer surfaces of the boiler. The drawing documentation of the steam boiler is available in the attachment of the thesis.
