Performance of Cr3C2-25(Ni-20Cr) and Ni-20Cr Coatings on T22 Boiler Tube Steel in Simulated Boiler Environment
Abstract: Corrosion of metals is a dangerous process, due to which there is loss of metal by the attack of corrosive agents. The high temperature corrosion causes fast material degradation which results in failure of components. Boiler tubes in the thermal power plants are subjected to corrosion due to high temperatures. Thermal spray coatings have been used to reduce the corrosion of boiler tubes. In this research paper an attempt has …

Voltage and Power Quality Control in Wind Power Application by Dynamic Compensation
Abstract: Power quality problem is a critical problem in a power system. Most of the pollution problems created in power system is due to the nonlinear nature of loads. Due to large amount of non-linear equipment, impact and fluctuating loads (such as locomotive, arc-furnace, welding equipment, etc.); wind power as a rule, does not contribute to voltage regulation in grids. Also wind power very often is a source of voltage sag …
