| Abstract [eng] |
In the introductory chapter of the master work the importance of the theme is presented as well as the aim of the work (development of 3D CAD model of the boiler and its testing) The first chapter industrial boiler types are presented and their use in everyday life, their work principal and a few aspects considering safety issues. The second chapter shows the boiler efficiency principals are shown as well as the technical characteristics of the experiment boiler version is presented along with the heating system and the work principle of a heating boiler fired with wood logs designed for heating various premises with closed heating systems and for production of domestic hot water The third and fourth chapters present new upgrades for the boiler with 3D CAD model, as well as all the test results that were performed which show the boiler performance coefficient and other required parameters. The boiler was tested according to the LST EN 303-5 standards, by which the boilers thermal power and the concentrations of CO,CO2,CxHx NOx will be shown. The fifth chapter contains list of expenses of both new and old boilers, which show all the expense elements, factory costs and added value of both products. The conclusions summarize results of the tests and received information about the new B-25E boiler performance. |
