Boiler & Generator LDO

Light Diesel Oil falls under class C category fuel having flash point above 66ºC. It is a blend of distillate components and a small amount of residual components. It is marketed under BIS 1460-2000 specification for Diesel fuels. Whereas HSD is used as a fuel for high-speed engines having 750 RPM and above in most of the prime movers used, LDO is used in lower RPM engines. It is used in Lift irrigation pump sets, DG Sets and as a fuel in certain boilers and furnaces. It meets same specification as for HSD except that, in case of HFHSD, flash point is stipulated as minimum 66º C, against 320 C, for normal HSD. This is specially recommended for use in diesel engines for Naval applications and Merchant Navy. This is also used by fisheries department for their fishing trawlers.
