What is the requirement of the flash point value of phosphate ester against fuel used in power plant?
According to DL/T 571-2014 Phosphate resistant fuel operation and Maintenance Guidelines for power plants, flash point requirements of new phosphate resistant fuel are as follows: Open flash point requirements :≥240℃
In operation, phosphoric acid value and fuel flash point value requirements are as follows: open flash point requirements :≥235℃
According to DL/T 571-2014 Phosphate ester fuel resistance Operation and Maintenance Guidelines for power plants, flash point value is measured by GB/T3536, SH106B automatic open flash point tester. Is in accordance with the People's Republic of China standard GB/T 3536, GB/T267 "petroleum products flash point and flash point determination (Cleveland opening cup method)" the requirements of the design and manufacture also support GB/T1671-2008 plasticizer flash point determination ASTMD92.
Open flash point is mainly used to measure gasoline engine lubricating oil, diesel engine lubricating oil, compressor oil, refrigeration
Engine oil, steam turbine oil, gear oil, mechanical oil, oil resistance, etc
