The aim of this project is using the CAE system to analyze the distribution of the temperature profile brazing furnace DIMA 0180. To create the model is used SolidWorks Premium 2012. The simulation is performed using the Flow Simulation. This work builds on the knowledge diploma thesis by Martin Procházka titled The effect of different heat capacities and components on the longitudinal temperature profile for reflow soldering. We start from the knowledge of heat transfer, especially of heat conduction and radiation, which appear in the furnace.

This work thoroughly analyzes a previously created computational model for predicting characteristic properties of the combustion process in an experimental combustion chamber. Any found shortcomings of the original model are removed and the model is further improved prior to its application on 11 real cases of combustion tests performed at various conditions and with various fuels. Data provided by the model are confronted with the data obtained during the combustion tests and the model accuracy is evaluated, based on local heat flux along the length of the combustion chamber. Finally, the overall usefulness of the model is determined by the means of evaluating the acquired accuracy values, and further possibilities of model improvement and use are presented.

The diploma thesis is dealing with selected parts of construction technology project of extension Vysoká pec no. 1 in Ostrava – Vítkovice. This thesis contains detailed elaboration of technological specifications for the construction of structural steel superstructure. For this phase is treated with a draft of mechanical report, inspection and test plan, dealing with traffic routes and itemized budget. There is also processed a proposal of building equipment which is the same for the entire implementation extension of Vysoká pec, a situation of building equipment, technical report of the object, the timetable for the entire project, ecology, health and safety.

The aim of this work is optimalisation of induction furnace in foundry for company PROMET FOUNDRY a.s. The company has two induction furnances. There are installed as identical construction. They have 2 modes of operation. First mode is founding and second mode is mode, where is temperature in maintain mode. Only one induction furnance can work in the founding mode at a time though. Inducion furnances are in the single-phase connection and they cause unbalance in the distribution network. Near the foundry there is a small network area whitch it is operated by company Zásobování teplem Vsetín a.s. The consumption of electrical energy in foundry so big, that in the year 2009 was made elaborate for Zásobování teplem Vsetín a.s. It was write at Laboratoře diagnostiky výkonů (Laboratory of performance diagnostics), which is a part of Electrotechnic Department at Technical Univarsity of Ostrava. The ordered study was named “Verification of causes of increased reactive energy consumption during transition from electricity delivery to electricity consumption”. The conclusion of this assignment confirms that in distribution network in the Jiráskova area in Vsetín there is unbalance of electrical energy and there is high part of reactive power. The next conclusion is crucial to find the customer who made the unbalance and to set relevant remedy. The last step will be the identification whether such device can actually be effectively balanced. It was subsequently proved that the Promet Foundry was causing the unbalance and that balanced consumption would be reasonable. Promet Foundry thus addressed Autel a.s. company with an inquiry to make a study of removing the causes of the unbalance which is caused by current induction furnaces operation at a minimum possible cost, least possible influence on the performance and minimum construction changes concerning the building. In this thesis there will be some topics. The result of which will be introducing of used heating technology, introducing of company and of effective plant performance and subsequent suggestions of possible unbalance removal or reactive power decrease. Several ways which are being implemented in the industry in order to balance consumption will be described. A suitable balancing plant will be subsequently chosen and its parameters will be calculated.

The diploma thesis solves construction and technological preparation of the transport terminal in Pec pod Sněžkou. The content of the diploma thesis is a techical report on the construction technology project, the coordination situation, the time and financial schedule, the project of building site, selection of machines, time schedule for the main building object, plan for securing material resources for the main building of the transport terminal, technological prescription and inspection and test plan for monolithic ceiling structures. Another assignment part contains a plan for safety and health protection at work on the construction site and specialized topic is a noise study.
