Energy efficiency of glassmaking production

Master’s thesis Energy efficiency of glassmaking production gives description of glassmaking production and possible energy saving measures. Due to the high electricity and fuel prices the problem of rational energy utilization rises sharply. In addition the environmental issues also require a great attention. This work represented the feasible increasing of the furnace efficiency as the most productive activity. Thesis also provides a detail description of utilizing waste heat boiler. Also possible boiler characteristics are calculated and represented at the end of the thesis. As well as brief description of the feasibility of using this method of energy saving. The solution of this problem has a huge importance. Due to the increasing of energy costs and limits of raw materials, glassmaking industry should overcome on high efficiency operation mode. Especially, if such measures is making a significant contribution in the safety of environment.

Investigation of the applicability of LVDC microgrids in utility distribution in Russia

The research towards efficient, reliable and environmental-friendly power supply solutions is producing growing interest to the “Smart Grid” approach for the development of the electricity networks and managing the increasing energy consumption. One of the novel approaches is an LVDC microgrid. The purpose of the research is to analyze the possibilities for the implementation of LVDC microgrids in public distribution networks in Russia. The research contains the analysis of the modern Russian electric power industry, electricity market, electricity distribution business, regulatory framework and standardization, related to the implementation of LVDC microgrid concept. For the purpose of the economic feasibility estimation, a theoretical case study for comparing low voltage AC and medium voltage AC with LVDC microgrid solutions for a small settlement in Russia is presented. The results of the market and regulatory framework analysis along with the economic comparison of AC and DC solutions show that implementation of the LVDC microgrid concept in Russia is possible and can be economically feasible. From the electric power industry and regulatory framework point of view, there are no serious obstacles for the LVDC microgrids in Russian distribution networks. However, the most suitable use cases at the moment are expected to be found in the electrification of remote settlements, which are isolated from the Unified Energy System of Russia.
