“…Lyublinski [21] studied synergistic corrosion management systems by use of corrosion inhibitors. In continuation to our earlier study [22][23][24][25][26][27], in the present study, the inhibiting properties of Diallylamine (DAA), 1-Benzylamidazole (1-BIZ) and 5-Aminotetrazole (5-ATZ) were investigated on mild steel at 85 % relative humidity and 50 °C by Weight loss test, Salt spray test in a solution of 3.0 % NaCl, Eschke test, SO 2 test, Metallurgical research microscopy and Scanning electron microscopy (SEM).…”

Mild Steel and their products are main raw material for a strong infrastructure for every country which is the main demand in the race of survival, stabilization, growth and competition. Industrialization and modernization in now a days has made a strong demand of steel and their maintenance but atmospheric corrosion can aggressively accelerate the degradation of steel during their manufacturing, processing, storage and transportation. In these cases, traditional methods to prevent corrosion are not suitable which provide the scope of Vapour Phase Corrosion Inhibitors (VPCI) in industries, defense and daily life. Three new VPCI namely Diallylamine (DAA), 1-Benzylimidazole (1-BIZ) and 5-Aminotetrazole (5-ATZ) were tested for mild steel in different aggressive atmospheric conditions by Weight Loss Test, Eschke Test, Salt Spray Test, Sulphur dioxide (SO 2 ) Test at 50 °C and results of these tests were supported by Metallurgical Research Microscopy and Scanning Electron Microscopy (SEM).

“…In power boilers, typical pressure elements are inspected in accordance with applicable regulations, taking into account the operating pressure [31][32][33][34][35][36][37][38]. However, it is important to note that the actual stress on these elements is a result of all the loads they experience, including forces caused by gravity that are 'maintained' by hanger rods.…”

Fibre optic sensors with integrated Bragg gratings are widely used in the diagnostics of machinery and equipment. They achieved their popularity thanks to their relatively simple operating principles. In addition, they allow the continuous monitoring of several variable physical parameters of objects, such as strain or temperature change, which directly translates into immediate feedback regarding potential damage. However, despite the easy-to-understand operating principle, selecting a specific type for a particular application can be problematic. This article aims to present the process of selecting the optimal set of fibre-optic sensors with integrated Bragg grating, which can be used in the process of monitoring the stress state of hanger rods of an engineering object such as an industrial boiler. The hanger rods of such boilers require constant technical supervision; however, the current measurement methods do not provide an effective and non-invasive diagnostic method. Therefore, the authors have undertaken the task of developing a universal diagnostic strategy for hanger rods. To this end, they will present the results of an analysis of the applicability of FBGs, examples of the use of different types of sensors, their installation methods, and the technical capabilities of the equipment necessary to handle the signals recorded with these sensors. Exemplary results of strain measurements of a selected hanger rod performed by the traditional method used now and with a selected FBG fibre optic sensor will be presented. In conclusion, concrete technical suggestions will be presented to be implemented in the existing industrial facility during the next part of the study.

“…The conventional form of SERD scheme recovers part of the energy that would be dissipated in the rotor and feeds it back to the supply through the inverter and thus provides a simple and efficient scheme of ac variable-speed drives [1][2][3][4]. Nowadays, such a system, also known as Static Scherbius system, is widely used for the limited speed range applications such as large-capacity pumps and fan drives, variable-speed wind energy systems and ship-board variable speed/constant frequency system [5].…”

In this paper, the harmonic analysis of inverter voltage of a slip energy recovery drive (SERD) is carried out and proposes a novel approach to improve the supply side power factor of the overall drive system. The proposed model is a self-commutated SERD using IGBT inverter, and a modulation technique called selective harmonic elimination (SHE) is applied to improve the supply side power factor. The complete solutions for switching patterns to eliminate the fifth and seventh harmonics are developed using genetic algorithm. SHE method is simulated in semiopen-loop mode, and the power factor of the drive is compared with conventional line commutated thyristor inverter-based SERD. Simulations have been carried out in Matlab/Simulink environment to predetermine the performance of the drive, and results show a significant improvement in the input power factor of the drive.
