steam boiler for wood biomass 25t/h,5,5MPa, 475°C
Pecháček, Michal ; Kohout, Přemysl (referee) ; Skála, Zdeněk (advisor)
The work deals with design of steam grate boiler with a output of 25 t/h, parameters of steam output p = 5.5 MPa, t = 475 °C and a temperature of feed water 105 °C. It is a boiler with natural water circulation by evaporation surfaces. Wood biomass is boiler fuel. The proposal consists of stoichiometric calculations, determination of boiler efficiency, thermal calculations and determinion geometric parameters of the boiler and its heat transfer surfaces. The boiler drawing is a part of the work.

Autosalon TOPCENTRUM in Hodonín, implementation of carcass superstructure
Pecháček, Michal ; Nečasová, Barbora (referee) ; Kovářová, Barbora (advisor)
This bachelor thesis deals with a construction technology procedure gross superstructure of a car store TOP CENTRUM car in Hodonín. This object has got 3 floors. One of them is underground and two of them are above-ground. The interest area is located in a flat terrain in industrial zone. Supporting system of the building is formed by steel skeletons and supplemental supporting structure of POROTHERM blocks. Ceilings are formed by prefabricated prestressed reinforced concrete panels and also by steel construction. The roof supporting system is made up by trusses and purlins and aslo by steel beams IPE. The construction and technological study of the gross superstructure includes a technical report, plan of routes, technological instruction of steel vertical supporting system and selected part of roof system, plans of inspections and tests, resolution of the building organization, schedule and budget, machine list and occupational safety.
