Authors:

Andrii Kulikov, Marcel Fedak, Milan Abraham, Jakub Vahovsky

Abstract:

The main idea of exploitation combined heat and energy production is to reduce usage of primary fuels and with that connected reducing of pollutions due to the integration of renewable energy sources and with regard to the natural environment. Presented work is analysis of CHP system producing electricity and compare to conventional systems.

Title:

Aspects of Determination of Convective Coefficients

Authors:

Ivan Čorný

Abstract:

The paper deals with selected aspects in the determination of convective coefficients and the formation of air convection models on solid surfaces. The goal is to assess the suitability of individual approaches for application in specific situations, considering that convective heat transfer coefficients have a significant impact on the resulting accuracy of the facilities/process design. Convection is a dynamic phenomenon, its exact physical description is complex, convection coefficients cannot be measured directly. Correct determination of convective coefficients is therefore very important in various areas where thermal energy is transmitted in this way. The paper gives an overview of selected aspects of various methods for determining convective heat transfer parameters.

Title:

Combustion Cleaning Methods in Dangerous Waste Incineration Houses

Authors:

Peter Oravec

Abstract:

Two (dry and semi-dry) methods of cleaning the combustion products from the dangerous waste incineration process are discussed in terms of the environmental (emission limits, waste and emission volumes, etc.) and economic criteria (material balances) as well as the plant service life and operation. The dry combustion product cleaning method as a BAT technology is recommended as the most suitable one.

Title:

Assessment of Temperature Ratios During Operation of Pneumatic Artificial Muscles

Authors:

Miroslav Rimár, Peter Šmeringai, Marcel Fedák, Milan Abraham

Abstract:

: The article deals with the description of experimental measurements performed to describe problematic point real-time temperature measurement of PAMs surface. The original measurement method was replaced by an alternative thermovision measurement. Thermal images were created at predefined times of operation of the device and its predefined operating states. Experimental measurements have shown that the temperature range of the PAMs is within the temperature range that limits the safe operation of the device.

Title:

Increasing of Utilization Efficiency of the Produced Energy in the Biogas Plant

Authors:

Ľuboslav Straka

Abstract:

The current trend not only in the world but also in Slovakia is to increase the share of energy obtained from renewable sources. Biogas stations also participate in the share of energy obtained from these sources. Today it is mostly modern and environmentally friendly technical equipment. They process a wide range of materials or waste of organic origin through the anaerobic fermentation process. Its result is biogas, which can be further utilized for the production of heat and electricity. However, the efficiency of the biogas production process is closely related to technical equipment of biogas plant. Also, biogas plant technology must, to the extent necessary, respect the conditions of its safe and reliable operation. The contribution is oriented to the design of a possible solution for increasing the efficiency of utilization of the produced energy in the biogas station.
