Abstract : The use of fire-resistant lubricants, of the phosphate ester type, in industrial gas turbines used for natural gas transmission is widely accepted. These fluids are more expensive than petroleum lubricants and a long service life is widely accepted. These fluids are more expensive than petroleum lubricants and a long service life is required to make their use economically viable. Little previous work has been done to develop methods for measuring thermal and oxidative stability of phosphate esters and the present report describes the adaption of two test procedures normally used for aircraft synthetic lubricants for this purpose. Test parameters were established using a long established proprietary phosphate ester fluid and then, using the same conditions, some fourteen candidate fluids were evaluated. In addition to the oxidation and thermal stability measurements, the fire reisstance of all the fluids were measured using manifold ignition and low pressure spray tests. (Author)
