Abstract
A heavy oil emulsified fuel evaporator system is provided in which a heavy oil emulsified fuel, after being preheated at a preheater, flows into an evaporator to be heated and then to a separator for separation of its water content. The water content, after being separated, is used as a preheating source medium for said preheater, wherein water content separation at a predetermined level is enabled irrespective of load change in a heavy oil fuel combustion equipment, and no light oil content is discharged together with the separated water content. Heavy oil emulsified fuel is preheated at a preheater , is heated at an evaporator and flows into a separator to be separated of its water content. Water content, after being separated, is sent via a piping to be used as the preheating source medium for the preheater . Inlet temperature of the evaporator is maintained constant, and pressure in the piping for leading the preheating source medium into the preheater is also maintained constant. Further, temperature difference of outlet temperature relative to the inlet temperature of the evaporator is maintained constant. Thereby, the water content in the heavy oil fuel coming out of the separator can be maintained at a predetermined value.
