A heavy oil emulsified fuel combustion apparatus is provided in which steam bubbles generated in the pressure reduction operation for dewatering a heavy oil emulsified fuel before combustion are prevented from mixing into a dewatered heavy oil side resulting in lowering of a dewatering efficiency. In a heavy oil emulsified fuel combustion boiler, a heavy oil emulsified fuel 101 is heated by a heater 110 and dewatered by a flusher 120 and then introduced into a boiler for combustion, and water 152 obtained by the dewatering is sent to a water utilizing system of the boiler. The heavy oil emulsified fuel 102 is heated in a high pressure and then introduced into a pressure reducing device 200 to be applied by a pressure reduction by multi-stage orifices 201 for dewatering. The pressure reduction is done with a pressure reduction per stage of 1 to 3 ata. -15-
