Abstract

1385949 Sewage disposal by combustion BABCOCK & WILCOX CO 26 July 1972 [17 Aug 1971] 34959/72 Heading F4B In a ship's sewage disposal system the sewage is treated, comminuted and delivered to a nozzle in the main furnace where it is sprayed into the combustion zone and burned. Fresh water at 9 is delivered to the ships galley, laundry and wash water system 10. The drainage 11 passes to a filter 12 from which part is drawn off by pump 15 to a sanitary water supply tank 14, the pump being controlled by sensors to keep the level in tank 14 at a desired level. This water is used in the sanitary system 19, the drainage 20 from which passes to disinfecting tank 18. The other part 17 of the water from filter 12 also passes to tank 18. Rotary agitators 21 keep the solids in suspension in tank 18 and the take off 30 passes to a main holding tank through a flow measuring device 32. Signals 33 from device 32 control the rate of supply of disinfectants from chemical mix tank 24. Overflow 42 from tank 31 passes to storage tank from which it is either recirculated by pump 44 via valve 47 or returned to tank 31 via valve 46. Both tanks have aerating means 38, 40 supplied with air by pump 35 also controlled by the flow measurer 32. Sewage 54 from the main tank 31 is discharged to a sump 55 containing a grinder 59 and a pump 58 for passing the comminuted sewage 60 to a centrifugal separator 61 returning oversize particles to tank 31. Tank 31 may be vented either to atmosphere 48 or to the outlet duct 86 of the furnace 85. Control valves 49, 51 are connected to operate together for this purpose. The output from the separator 61 is applied by pump 88 valves 66, 67 and flow measurer 65 to nozzle 73 which is inclined to direct its spray into the combustion zone of uel oil burner 77. Both nozzles are provided with steam for atomizing the spray. If the furnace is not being used or is operating at less than 50% of capacity the sewage is not delivered to the nozzle 73 but stored until the furnace is working at nearer full capacity.
