Kotel na spalování čistého dřeva 60t/h / Steam boiler burning wood 60t/h

Umýsa, Radovan January 2011 (has links)
This diploma thesis deals constructional and calculation design of the steam boiler 60t/h of clean burning wood. For the parameters of the stoichiometric calculations are carried out and enthalpy calculations of combustion and air. The collected data is then made It a diagram of air and flue gas. The following are the calculations with the heat balance calculations of losses and determination of the boiler thermal efficiency of the boiler. It is made of the combustion chamber design and its thermal calculation. After determining the main dimensions of the combustion chamber moves continue the calculation of boiler heating surfaces. At the end of the calculations are controlling the overall energy balance. Boiler output parameters as temperature, pressure and quantity of the steam.

Parní kotel na spalování dřeva 40t/h / Steam boiler for wood burning 40t/h

Mach, Ondřej January 2012 (has links)
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.

Parní kotel na dřevní štěpku 88t/h / steam boiler for woody biomass 88t/h

Lučko, Martin January 2012 (has links)
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.

Systém pro měření tepelné účinnosti solárních absorbérů / System for measuring of thermal efficiency of solar absorbers

Řiháček, Jan January 2013 (has links)
The thesis deals with the measurement system for determining the thermal efficiency of the newly developed types of solar absorbers. Measuring equipment allows simultaneous indoor or outdoor thermal efficiency detection of up to four samples absorbers. Emphasis is placed on the flow and heat transfer medium temperature changes. For this purpose is used Biotech FCH-m-POM-LC and LM35DZ sensors. Sensor signal is transferred to a PC using the measuring module NI USB-6221. Here it is further processed by proposed evaluation program. The software is implemented in LabVIEW integrated development environment. In a final part are performed a verification measurements to assess system performance and evaluate the thermal efficiency of various types of solar absorbers. This path is also demonstrated high efficiency applications absorbent layer coating color RABSORB 5.

Výpočtový systém pro vyhodnocení výrobních ukazatelů spaloven komunálních odpadů / Computational tool for processing of production data from waste-to-energy systems

Machát, Ondřej January 2013 (has links)
This thesis contains evaluation of crucial operational indicators of a waste-to-energy plant. Above all, it is lower heating value of municipal solid waste and boiler efficiency. An approach for evaluation improvement by mathematical methods is proposed. The approach is implemented in a computational tool developed in Microsoft Excel. The approach is tested and subsequently used for operational data from a real waste-to-energy plant.
