Mandatory Properties for Steam & Gas Turbine Oil.



1. Steam Turbine Oil
a) Good Demulsibility: Means the ability to release water, This is important when the equipment is operating in humid climates or in a plant atmosphere that is wet or humid.
b) Foam Suppression, and Air Release: Foam is used whenever there is a possibility of liquid fire. The Foam will mix with water and then expand over the liquid that is on fire, cool the fire, and will finally suffocate it.
c) Anti-rust protection: Rustproofing is the prevention or delay of rusting.
d) Anti-wear protection (Certain Cases): Antiwear additives (AW additives) are lubricant components that chemically react with Oil to protect metal-to-metal contact between parts of gears.
2. Gas Turbine Oil
a) Anti – Corrosion Protection: Help protect the base oil from oxidation and the metal from damage by corrosive acids.
b) Anti – Scuff (Certain Cases): Anti-scuff additives are designed to react with the parent metal surfaces to provide protection under severe loads and high temperatures where the oxide layers and chemically adsorbed anti-wear films on metal surfaces are disrupted.
c) Thermal Stability: Thermal stability is the stability of a molecule at high temperatures; i.e. a molecule with more stability has more resistance to decomposition at high temperatures. Thermal stability also describes, as defined by Schmidt, the stability of a water body and its resistance to mixing.
d) Deposit Control:

Control System Of Turbine - Failure & Maintenance

Image
Control System The turbine control system describes the control over the opening of control valves corresponding to demand signals, and steam flows into the turbine with the help of a governing system that facilitates the operation of the turbo set in an interconnected grid system. Governing system is responsible for various function such as speed & load control functions, the start-up/shut-down controls, the over-speed control, turbine stress calculation, to control the initial run-up and synchronization of the Unit, to assists in matching the power generated to that demanded by responding to system frequency changes, to regulate the steam control valves position (and hence the load generated)in response to signal from the operator or from the load dispatch Centre, to restrict the speed rise within acceptable limits should the unit get disconnected (islanding) from the lgridoad and some protective trip functions. With continuous research and developments in modern turbine technolo

Reconditioning of EH Oil

Image
A 1200 MW coal-fired thermal power plant using Into-Chinese Turbine EHC System in Southern India. The Plant was struggling with the rapid increase in TAN values in the EH oil of the governing system of the turbine. Also, the moisture content was more than permissible limits. Degradation of the oil was due to contamination ingression into the system resulting in by-product formation. Minimac’s EH oil reconditioning system “ MLC LVDH TRIX 20 ” proved to be the savior and an unexpected shutdown of the turbine worth ₹1.05 Cr per day was saved . PROBLEMS A rapid increase in the Total Acid Number (TAN) could degrade the EH oil and lead to the possibilities of failure of servo valve, hunting, power generation loss, unplanned shutdown, etc. Oil Analysis was done to check the properties of EH oil like Moisture, NAS value, Total Acid Number. SOLUTIONS Installation of Minimac’s EH Oil Reconditioning System “ MLC LVDH TRIX 20 ” is comprehensively designed with 4 major technologies to: Remove solid

 The secret recipe of the growth story at Minimac Syste ms has been its capability to drive technological advancement in the field of contamination control for lubrication reliability. Research and development on technology and products have always been the key reason to keep the Minimac products a step ahead of its competitors in the market. Technological development has been one of the core competencies which Minimac possesses, thereby ensuring a definite competitive advantage. Contaminations in lubricants are of various types and characteristics depending on the lubricant, equipment application, ambient conditions, age of equipment, etc. In order to control, separate or eliminate the contamination, there are multiple techniques. Each technique has pros and cons and hence there is no single technology that can be considered universally better than others. ​ Minimac Systems over the years has become equipped with almost all the technologies which are required for contaminat
