The aim of this diploma thesis is the construction design of the steam boiler burning pellets. Set parameters: 450°C; 5,2 MPa; 30t/h. Decision procedure: stoichiometric calculation, energy balance, calculation of combustion chamber and heat delivery surface.

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.

The thesis contains calculations of a boiler burning natural gas. For designated values of steam pressure, temperature and steam power is made a proportion design and heat calculations.

To design a grate boiler with a natural circulation for burning of a pine bark with an output 18t/h is a primary objective of this dissertation. Individual parts of a boiler and it´s heat transfering surfaces were calculated after the working out of stoichiometric calculations from given element analysis of fuel. All computations have to fulfill several parameters: boliler output, temperature and pressure of an overheated steam.

The work deals with design of steam grate boiler with a output of 25 t/h, parameters of steam output p = 5.5 MPa, t = 475 °C and a temperature of feed water 105 °C. It is a boiler with natural water circulation by evaporation surfaces. Wood biomass is boiler fuel. The proposal consists of stoichiometric calculations, determination of boiler efficiency, thermal calculations and determinion geometric parameters of the boiler and its heat transfer surfaces. The boiler drawing is a part of the work.

The work is focused on the design heat generation source in my chosen location. The entire facility should be designed to meet the basic requirements of the client. The primary objective of this work is alternatively propose solutions to perform basic balance calculations and determine the performance of each device. Based on the location selected diagram to produce annual heat needs and recommend the best possible solution.

The topic of master thesis is the thermal calculation and proportion design of gas-fired steam boiler. The first part describe technical characteristics and parameters of the boiler. The main part of this thesis is the thermal calculation of the boiler.

This thesis deals with a project of steam boiler to combustion of refused-derived fuel. Considering the required fuel and output parameters of the steam was made the thermal calculation of boiler with it design and an individual calculation of heat exchange surfaces; hydrodynamic and aerodynamic calculations of the steam boiler.
