![]() ![]() ![]() Almost 90-95% of turbine oil is a base oil with additives making up the remaining per cent which includes antioxidants, rust inhibitors, metal deactivators, antifoam agents, demulsifier, pour depressants and antiwear additives. Modern technologies in lubrication science show clearly a great advancement in the formulation of the turbine oil. Important roles of oil are cooling of bearings & journals, flushing contaminants away from rotating parts, preventing in leakage of gases, providing hydrostatic lift for shafts, actuating valves in the hydraulic circuit, and protecting lube-system internals. ![]() Turbine oil has to undergo through an adverse condition like large temperature fluctuation, heavy load, ingress of contamination, moisture, entrained air, heat and many physical & chemical changes. However, the OEM of the turbine carefully specifies the characteristic of the lubricants, laboratory test for oil analysis and standard references for the best performance of the turbine. Its reliability and availability critically depend on the turbine oil, which makes the lubricant selection very important part in the reliability program. In the Power plants, Turbine is the most crucial machine which is the prime movers for other rotating equipment and hence the generation of electricity. To meet this ever-increasing demand, power plants are delicately performing to improve their output and reliability. In this growing modern world where electricity has become the most important part of our life and spending a day without it could slow down our lifestyle, productivity and overall impacting the global economy then the generation of electricity indeed became fundamental to us. Sometimes it is done by controlling water flow through oil coolers. A Temperature Control Valve (TCV) is provided to by-pass the coolers when the oil temperature is low, to ensure correct oil viscosity and efficient lubrication.An accumulator for minimizing pressure surge when any operational change occurs, like switching-over between main and stand-by equipment.In addition, one pressure relief valves to protect the pumps from overpressure (usually rotary type).Pressure control valve to regulate an exact and constant supply oil pressure to the bearings.Oil filters to remove erosional debris from the circulating oil.Oil coolers to dissipate the heat from the oil during operation.Oil pumps to provide the necessary level of oil pressure.Oil system which is composed of an oil tank (with a heater for a start-up).Let’s understand a brief of oil flow along with major component and its function in the lubrication system of the turbine with the following steps: This mechanical energy is used to drive rotating equipment like pumps, compressors, fan, blower, and ultimately to drive a generator for the production of electricity. The turbine which is the heart of the power plant extracts thermal energy from high-pressure steam and converts it into mechanical energy on a rotating output shaft. In this article, we have tried to cover the maximum information about turbine oil which could help the power generation & manufacturing industries to move further with a cost-effective sustainable solution. Nowadays the industries are more focused on extending the life of both lubricants and the equipment by implementing a robust Reliability lubrication Program. Turbine oil manufacturers are continuously working with OEMs to provide high-performance turbine oils to meets the rising demands globally. The market studies done by the various analyst on “Global market analysis on Turbine oil “forecast that the global turbine oil market to grow at a CAGR of 3.498% during the period 2017-2021 and the market size has a potential to grow by 1500.05 K MT during 2020-2024, and its momentum will accelerate during the forecast period. ![]()
