The aim of this thesis is a draft of a gas steam boiler with steam output of 200 t/h. The first part of the paper provides stoichiometric calculations, then there are calculations of the dew point, boiler efficiency and the amount of gas. After that, calculations and a draft of the combustion chamber are carried out and then heat balances are drafted. In the following text, geometric properties of individual heat exchanging surfaces are drafted. At the end, there are control calculations. This thesis contains a blueprint of the gas steam boiler.

The final thesis deals with the heating plant with piston steam engine design according to heat consumption background in the location of Velky Karlov and with the design of a heating scheme including its explicit parameters. Further on it deals with the possibilities of the heating plant output regulation and with the solution of natural gas and biomass heating plant operations aside the heating period.

The aim of this work is to introduce technology sufficient of usage for treatment of biogas to the quality of natural gas and to propose and to realize an experiment in finding effectivity of one of these methods.

The dissertation is concerned with a problem of condensing boilers. The attention will apply to the condensing boiler which is filled in an absortion springle for a better an-nealing of exhaust gas. On this account the dissertation is possible to divide by some parts. There is a generally resolution of a condensing boiler´s principle and an effective annealing of exhaust gas for low temperatures in the first part. A description of an ab-sorption circulation follows in the second part. A practical part solves a suggestion of the condensing boiler with an absorption afterheat removal springle, an assesment of working parameters and a calculation of heat transfer surfaces. A technoeconomic ana-lysis of a proposed arrangement is made in the final part.

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.

This diploma thesis describes the design of steam boiler for combustion natural gas, which has a steam power 80t/hour. In the first phase is performed calculation of stoichiometric amount of combustion air and flue gas. After that follows constructional proposal of the combustion chamber. Furthermore continue by calculation heating surfaces of the boiler. In conclusion, the thesis is focused on designing the injections. To check the accuracy of the results is recalculated heat balance the whole boiler.

In this work, there is an overview of the design concept of condensing boilers and types of heat pumps. The current state of heating in company is assessed and possible variants are given for techno-economic evaluation. For boiler room with the gas boiler is prepared a proposal with condensation boiler. For parameters are designed and calculated proposals to form a condensing boiler. The end of the work is focused on the advantages of gas boiler and heat pump.

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 master´s thesis is dealing with the thermal calculation and design of boilers for natural gas combustion. The aim is to design the heating surfaces, so as to meet the requirements of the steam temperature of 490 ° C, the pressure of 7 MPa and the steam output of 60 t/h.

This thesis deals with the fuel change for hot water boilers with wattage of 116.3 MW. At first a stoichiometric calculation is drawn. Calculation of pressure loss in pipeline follows. Consequential part elaborates on calculation of parallel connected heating surfaces following with a draft of regenerative air heater Ljungtröm. Conclusively, a calculation is carried out to verify the functionality of the serial connection of the heating surfaces.
