Experimental verification of a gas micro-turbine cogeneration system
Buřil, Lukáš ; Konečná, Eva (referee) ; Máša, Vítězslav (advisor)
This master’s thesis deals with problematics of natural gas microturbine integration into industrial laundry operation. This integration means utilization of waste heat for direct drying and water heating in a heat exchanger. This heated water can be used in further laundry processes, for example laundering. All the experiments were carried out on the cogeneration system that is installed in Laboratory of Energy Intensive Processes in NETME Centre at the Faculty of Mechanical Engineering of Brno University of Technology. This system consists of a natural gas microturbine Capstone C30 with nominal electric power of 30 kW, an industrial dryer Primus DX55 with a nominal capacity of 55 kg for laundry and a heat exchanger Vakading type Vakavlas with nominal power of 53 kW. All necessary theoretical and technical preparation was done in order to carry out experiments as follows: • Standard drying program • Water accumulation test • Test of performance of heat exchanger • Direct drying with the use of microturbine’s flue gases These experiments were analyzed and discussed within this thesis. The main contribution of this work is as follows: • Summary of all the knowledge in the area of direct drying • Creation of methodology of utilization of flue gases for direct drying not only in laundry industry but in related fields • Summary of requirements and ways of heat exchanger testing and determination of heat exchanger parameters • Determination of optimal working settings of installed cogeneration system • Description of weak spots in the system and suggested improvements • Basic economic analysis of operating costs During the experiments, it was found that in case of direct drying better results could be achieved in comparison with standard drying. The functionality of the whole system together with the heat exchanger was verified and thus also the possibility of integrating the turbine into the washing process was confirmed. The integration of a natural gas microturbine is both technically and economically feasible for many industrial applications.

Control of gas microturbine equipped with waste heat recovery system
Kijanica, Michael ; Konečná, Eva (referee) ; Máša, Vítězslav (advisor)
This bachelor’s thesis deals with control of the cogeneration system which utilizes waste heat from gas microturbine. This complex cogeneration system was created in Laboratory of Energy Intensive Processes NETME Centre and its main purpose is the research in utilization of high temperature flue gas from Capstone C30 microturbine for drying laundry. In case of implementation of similar cogeneration system in industrial or commercial laundries, it is necessary to design automatic control of such system to make laundry - operations easier, minimizing energy waste and maximizing safety.

System for heat recovery of gas microturbine flue gas
Vilda, Dalibor ; Jícha, Jaroslav (referee) ; Máša, Vítězslav (advisor)
The theme of the work is the integration of gas microturbines in industrial plants. The aim is to extend the application potential of this technology by the design of the integration into the process in which this technology is not exploited yet. This process is a professional laundry service. Professional laundry services have been selected as a representative of the generally known process, which is interesting in terms of energy intensity. Combining of progressive cogeneration technology and enhanced industrial process brings a promising application potential. The work focuses on small industrial laundries to 500 kg of processed linen per shift. As a cogeneration unit a gas microturbine Capstone C30 has been used. The microturbine has an adequate power due to the process. Complete laundry operation and a gas microturbine is a part of the equipment of the Laboratory of energetically demanding processes in the NETME Centre. The main contribution of this work is to design a system for utilization of flue gas heat for heating of the main input currents to the laundry room, a hot water for washing machines and warm air for drying in the dryers. The integration of the gas microturbine made to suit specific process can be a major cost-saving measures with positive impacts on the economy of operation.

Patented solutions of professional laundry machinery
Čermák, Martin ; Kšenzuliak, Vladimír (referee) ; Bobák, Petr (advisor)
The subject of the thesis is national and international legal protection of technical solutions of professional laundry machinery with a view to a patent review creation procedure. The output is the review of already legally protected solutions relating to the reduction of industrial laundry energy consumption. The part of thesis is also a brief summary relating to the professional laundry care process.
