is an indication of the amount of noncombustible material present in the oil indicates the quantity of energy released by burning a unit amount of the fuel is useful for determining proper atomization temperatures reflects the overall thermal efficiency of the fuel oil service system
Proper timing Accurate metering Suitable injection rate Suitable atomization rate
fuel oil pump will over-speed if dirt is not removed fuel oil transfer pumps cannot tolerate small amounts of dirt in the oil fuel injectors may be damaged by foreign particles in the fuel oil dirty fuel will clog the intake air filter
deliver proper fuel quantity to the injection nozzle provide rapid fuel injection cutoff control fuel quantity entering the pump body control fuel pressure delivered to the combustion chamber
relieve excess fuel oil pressure during the “off ” fire cycle admit water to the dry pipe throttle the forced draft fan output for proper combustion reduce excess steam pressure in the boiler
create turbulence in the combustion chamber aid in completing cylinder scavenging inject fuel at the proper time minimize fuel penetration into the cylinder

all excessive amounts of growth will cause the main engines of the vessel to stalldue to the inability to supply the proper quantities of fuel to satisfy the existing load The deposits produced by these growths form blockages and flow restrictions ultimatelyleading to improper atomization of the fuel into the cylinders Eventually the growth of these organisms will deplete the supply of food availableto them, which in turn will cause their demise If continual growth is permitted, a sweet odor similar to that associated with bakingwill be noticed when system components are opened for inspection
affect the injection pressure improve combustion reduce compression pressure decrease power output
proper fuel metering complete fuel/air mixing minimal fuel penetration proper fuel timing
proper fuel injection water in the fuel incomplete combustion burning of lube oil

fuel treatment fuel combustion fuel injection fuel separating
the elimination of valve wear improved atomization a decrease in cylinder blow-by an increase in cylinder blow-by
delivering the same quantity of fuel to each cylinder for each power stroke accordingto engine load maintaining the metering adjustment for a reasonable period under all load conditions timing fuel injection to obtain maximum power and good fuel economy distributing the fuel to all parts of the combustion chamber for proper combustion
