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.

The aim of the work is to design a plain wood combustion boiler of 88 t/h output. Fuelling component analysis has been added to the basic boiler parameters. For given fuel is prepared stechiometric calculations. After making the heat balance of boiler is determined the thermal efficiency. For given output of steam parametrs (temparature, pressure, volume) are designed individual convective surfaces and dimensons of the boiler. It is also made drawings.

The topic of this thesis is the thermal calculation of steam boiler with natural gas fuel. The first part is describing technical characteristic and parametres of the boiler. The main part of this thesis is the thermal calculation of the boiler. The following part deals with determination of steam amount and steam parametres for blowing through pipes of the boiler.

The aim of this thesis is design a grate steam boiler for burning straw with an output of 10 tons of steam per hour. The produceds team has parameters 320 °C, 3,2 MPa. For a given fuel (fytomass) is calculated stoichiometric calculation. The following is the calculation of the heat balance of the boiler including the determinativ of thermal efficiency. The fuel used, the required parameters of steam and feed water temperature are designed individual convective surfaces and dimensions of the boiler. The boiler design includes drawings.

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.

The main aim of this diploma thesis is to proceed a design of grate steam boiler for grain straw combustion with 15,6 MJ/kg of fuel efficiency. Steam power of boiler is 15 t/h, pressure of overheated steam is 5 MPa, temperature of overheated steam is 415 °C and temperature of inlet water is 125 °C. The estimation is based on proportioning of draughts and segments of boiler and on thermal computation. Verification of divergence of thermal balance is going to constate accuracy of boiler design.

The work deals with the constructional and calculation design of the boiler for burning wood and combustion coal in scale (30/70-coal), in load 50 t/h, parameters of steam output p=7,5 MPa, t=480 °C and a temperature of feed water 105 °C. It is a boiler with natural water circulation by evaporation surfaces. In proposal first steichiometric calculations and enthalpic calculations of air and flue gas are performed. Then it is calculated heat balance, the boiler losses and the thermal efficiency is determined. After designing the combustion chamber and dimensions of pulls are determined. In last chapter the overall energy balance are checked. Drawing documentation of steam boiler is a part of the work.

The thesis deals with steam boiler design of 88 tons per hour capacity and with the outlet steam parameters of 9,6 MPa and 520 °C. Fuel for boiler is wood chips. The main focus of the thesis is on heat calculation, design of dimensions and layout of heat surfaces. The thesis also include drawing of steam boiler.

The thesis includes design of steam boiler burning woodchips with parameters of steam 88 t/h, 9,6 MPa, 520 °C. For these parameters is processed a heat calculation and dimensional design of boiler.

The aim of a diploma thesis is design of draft boiler for co-firing blast furnace gas and natural gas. In the first part is made the stoichiometric calculation for the gas mixture. Next is the proposal of combustion chamber and proposal of individual heating surfaces of boiler. Next part contains the thermal calculation and control of individual heating surfaces. Part of the work is also drawing documentation of boiler.
