HEAVY OIL EMULSIFIED FUEL COMBUSTION APPARATUS

摘要

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 A LOWERING OF 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 (10) FOR COMBUSTION, AND WATER (152) OBTAINED BY THE DEWATERING IS SENT TO A WATER UTILIZATION 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 ATM. (FIG 1)
