Kotel na spalování smrkové kůry-18t/h / Steam boiler for spruce bark burning-18t/h

Dračka, Lukáš January 2012 (has links)
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.

Zvýšení výroby elektrické energie na BPS pomocí parního motoru / Increasing of electricity production in BGS using steam engine

Nahodil, Jiří January 2012 (has links)
This thesis deals with the possibilities of using waste heat for power generation with a focusing on biogas plants (BGS). The produced biogas is mainly used for combustion in cogeneration units with internal combustion piston engines. The first part this paper describes the biogas plants. The division of BGS and the biogas processing is mentioned there. Another part is focused on the combined production of electricity and heat. The principles and description various types of cogeneration technologies are presented here. The following are specific options for waste heat utilization for biogas plants. The last section contains proposals to increase electricity production by the BGS with the steam engine and economic evaluation of these proposals is made.

Parní turbina rychloběžná / High-speed Steam Turbine

Albrecht, Jan January 2013 (has links)
Main aim of presented master thesis is focused on construction of high speed steam turbine. Steam turbine is designed based on parameters of waste incineration plant in Brno. First chapters shortly summarized historical development, transformation process and work principal of steam turbine. Consequently on first captures is in depth described impulse and reaction blading including expansion in i-s diagram and basic equations for efficiency calculations. In major part of master thesis is firstly discussed conceptual possibilities of turbine application for given parameters. Based on chosen concept is compiled algorithm for thermodynamic calculation for each turbine module. Simplify calculation of gearbox is included as well. Based on calculations are compiled construction drawings of all parts of steam turbine.

Optimalizace Rankineůva-Clausiůva parního cyklu / Optimization Rankineůva Clausius-steam cycle

Čepl, Ondřej January 2013 (has links)
This diploma thesis deals with an optimization of Rankine-Clausius steam cycle. The theoretical information about the Optimization and the Rankine-Clausius cycle are described at the beginning of the thesis. These theoretical findings are later used to create simulation models in MATLAB. Individual simulation models are variants of the ideal R-C cycle. Simulation models include the basic cycle model, the supercritical cycle and the cycle with reheat. For these models the optimal configurations are found and their t-s diagrams are plotted.
