UCG is the process, which can be attractive from environmental and economic aspect and is able to have a wide utilization in the future. This technology is less expensive than conventional mining. For research and good analyze of this process there was created the physical model of the gasifier, that simulate the conditions of the real coal-bed in geometric similarity. On created physical model was performed a several experiments represent a various underground conditions. In the gasification process the input is the coal (coal-bed) and oxidizer (mixture of the air and oxygen), which suitable combination provides the best conditions for gasification. One of the expected outputs from the coal gasification process is the high temperature in the coal-bed, which enable running of the chemical reaction needed for the syngas generation. The control of this temperature in the single places of the coal-bed would enable to control behavior of the chemical reactions so the burning queue proceeds. The measurement of the temperatures inside the coal-bed is still complicated because there is the high thermocouples mortality in aggressively hot environment. For this reason is needed to use mathematic - physical apparatus for indirect measurement of these temperatures. In this contribution is presented proposal of the indirect temperature measurement structure in the coal-bed that was verified in the laboratory conditions on the experimental gasifier.","PeriodicalId":373601,"journal":{"name":"Proceedings of the 14th International Carpathian Control Conference (ICCC)","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121948884","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A test stand Rotor-kit for testing of the effect of rotors instability has been assembled. This system enables to control journal bearings for suppressing instability caused by an oil film actively. As actuators the piezoactuators have been used. The system of Rotor-kit has been designed in order to test different types of shafts such as the basic test objects. Tested shafts have different properties and are made from different materials. In this paper we focus on the measurement of three types of shafts where two shafts are from the magnetic material and one from the non-magnetic material. The magnetic shafts are divided on the hollow shaft and filled shaft. The laboratory measurement for verification of deviation measurement (instability) were carried out. The measurement result is measured data comparison from three different types of sensors namely sensor of deviations (digital micrometer), sensor based on eddy current (inductive sensor) and sensor based on capacitive principle. These sensors are basic measurement components of the Rotor-kit system and for rotor's instability suppressing is the verification of measurement results for used sensor types also very important.","PeriodicalId":373601,"journal":{"name":"Proceedings of the 14th International Carpathian Control Conference (ICCC)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114794371","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By selecting a suitable annealing process control of steel coils we improve the quality of annealed batch and economic efficiency of furnace operation. When selecting a suitable heat treatment for a specific application purpose, one starts by learning the desired metal properties and by acquiring knowledge about properties structures. One must also consider the structural transformations that take place in systems by temperature changes. Addressing the challenge of accelerating and improving the metal heating procedure is the main research and development direction of the current thermal technology in all industrialized countries in the world. Considering the introduction of new management technologies, it is important to take measurements, in a way to maintain the measuring uncertainties within required limits. In the annealing process (heat treatment of steel), the measuring the temperature inside the steel coils plays an important role. Because the direct temperature measurement cannot be performed for several reasons (e.g. processed material damage, thermocouples wear, difficult assembly of thermocouples into the coil and so on) it is necessary to utilize systems of indirect measurement. This article examines the impacts of a change on the sampling of the measured values frequency, directly in the process of steel coils annealing in regard to the quality of the recorded signal utilizing indirect measurements systems.","PeriodicalId":373601,"journal":{"name":"Proceedings of the 14th International Carpathian Control Conference (ICCC)","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116067349","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
