Heavy oil emulsified fuel evaporator system

摘要

A heavy oil emulsified fuel evaporator system includes a preheater constructed of a first heat exchanger (41) using steam as the preheating source medium and having a level switch (44a) and a second heat exchanger (42) communicating with the first heat exchanger via a flow control valve (44b) and using hot water as the preheating source medium. A heavy oil emulsified fuel evaporator system in which a heavy oil emulsified fuel (11a), after preheated at a preheater, is led into an evaporator to be heated and then to a separator (15) for separation of its water content, and the water content, after separated, is used as a preheating source medium for the preheater. The preheater is constructed of a first heat exchanger using steam as the preheating source medium and having a level switch and a second heat exchanger communicating with the first heat exchanger via a flow control valve and using hot water as the preheating source medium so that the heavy oil emulsified fuel to be heated is flown to the first heat exchanger from the second heat exchanger.
