Method and apparatus for incinerating combustible wastes
Abstract
Abstract A CONTROL SYSTEM FOR A FLUIDIZED BED REACTOR WHICH IS USED FOR TREATING MATERIAL. ALTHOUGHTHE CONTROL SYSTEM IS PRIMARILY DESIGNED FOR USE WITH A REACTOR WHICH IS USED FOR INCINERATING COMBUSTILE WASTES SUCH AS SEWAGE SLUDGE, OILY WASTES SUCH AS OILY WASTES FROM AN OIL REFINING OPERATION OR OTHER COMBUSTIBLE WASTES, IT MAY ALSO BE USED WITH A REACTOR WHICH IS BEING USED FOR OTHER HIGH TEMPERATURE OPERATIONS SUCH AS CALCINING OPERATIONS. FUEL AND QUENCH WATER ARE SUPPLIED TO THE RECTOR TO MAINTAIN A DESIRED TEMPERATURE WITHIN THE FLUIDIZED BED. THE TEMPERATURE OF THE FLUIDIZED BED IS MEASURED AND COMPARED TO A SET TEMPERATURE. THE DIFFERENCE BETWEEN THE ACTUAL TEMPERATURE OF THE FLUIDIZED BED AND THE DESIRED TEMPERATURE CONTROLS THE SUPPLY OF EITHER FUEL OR QUENCH WATER TO THE RECTOR TO MAINTAIN THE ACTUAL TEMPERATURE OF THE BED EQUAL TO THE DESIRED TEMPERTURE. THE TEMPERATURE OF THE FREEBOARD AREA ABOVE THE FLUID BED IS ALSO MEASURED AND COMPARED WITH A DESIRED TEMPERATURE. A CONTROLLER RESPONSIVE TO THE DIFFERENCE BETWEEN THE DESIRED TEMPERATURE OF THE FREEBOARD AR EA AND THE ACTUAL TEMPERATURE CONTROLS THE VOLUME OF WSTES SUPPLIED TO THE REACTOR.
