Definitions

  • This invention relates to an improved batch"type incinerator where the incinerator is charged with a given amount of refuse or waste to be burned, ignited, and then burned o' completely before the incinerator is opened to the atmosphere, a new charge place therein, and the process repeated.
  • FIG. l is a schematic side elevation showing an incinerator arrangement having multiple loading chambers and a single exhaust stack.
  • FIG. 2 is an example of an alternate arrangement utilizing multiple loading chambers and a single exhaust stack.
  • the incinerator comprises a housing having a closed combustion chamber 12 with a loading port at one end through which waste may be loaded and an outlet port 16 through which gases generated therein may flow on their exhaust to the atmostphere.
  • the combustion chamber 12 generally comprises an outer jacket I8 of steel with an inner coating 22 of insulating material capable of standing up at temperatures of 2500 F.
  • a charging door 24 is provided to tightly seal the loading opening whereby it may be opened widely for ease of loading and then tightly closed to preclude the flow of air therethrough when incineration is underway.
  • the entire end 26 of the incinerator comprises a pivoted door that may be opened widely to permit repair of the housing or to provide for the removal of ashes resulting from the incineration process.
  • the outlet port 16 is connected to a branch of an inverted T"shaped outlet duct 20 housing a secondary combustion chamber 36.
  • a source of fuel 44 and air 3l together with an independent ignition means 48 is provided to initiate and sustain the combustion gases produced in either housing by the combustion of waste therein under less than stoichiometric conditions.
  • An outlet stack 38 is secured to the upright branch of duct 20 to vent the exhaust gases into the atmosphere.
  • the source of air 46 is provided whereby air for combustion may be supplied via ducts 30 to apertured undertire tubes 32 and via duct 3l to the secondary combustion chamber.
  • the inverted T"shaped outlet duct 20 enclosing the secondary combustion chamber 36 is secured to the housing at outlet 16 whereby all gases generated in the chambers l2 or 12A are forced to traverse the combustion chamber and then exhaust to the atmosphere through outlet stack 38.
  • Air for combustion of gas in chamber 36 is supplied thereto via duct 3l, while gas or other fuel is supplied via duct 44 and then ignited by ignition means 48 so that a predetermined temperature is maintained at thermocouple 52 in the secondary combustion chamber and at thermocouple 54 in the stack.
  • a second housing 10A enclosing a chamber 12A is provided with an outlet port connected to the secondary combustion chamber 36.
  • the chamber 12A is provided with a loading port 24A and a cleanout door 26A similar to that provided for chamber l2 at 24 and 26.
  • An apertured air inlet duct 32A provides underfire combustion air to chamber 12A from the same source 46 as that which supplies combustion air to chamber I2.
  • Valves 76 and 78 in the air supply lines may be operated manually or by thermocouple 54 and 56 in the stack to provide the combustion air necessary to support combustion of all gasses produced in the primary combustion chambers 12 or 12A.
  • Thermocouple 52 in chamber 36 controls the valve 82 for air from source 46 insuring continuous combustion of exhaust gases in the secondary chamber.
  • FIG. 2 shows a slightly modified arrangement whereby the primary chambers 13 and 13A are arranged in a spaced parallel relationship to permit loading said chambers alternately in accordance with the teachings of this invention.
  • Apparatus for the incineration of waste material comprising an incinerator housing enclosing a chamber with a loading port for the charging of waste material therein and an outlet port exhausting the products of combustion therefrom, an airtight closure door for the loading port, a branched outlet duct enclosing a secondary combustion chamber, means connect ing one branch of said duct to the outlet port of the incinerator chamber, a burner in said secondary combustion chamber including a source of fuel and air, an outlet stack, means connecting the outlet stack to a branch of said outlet duct, a second incinerator housing having loading and outlet ports, means connecting the outlet port of the second incinerator housing to a branch of said outlet duct, temperature responsive means in the outlet stack, and means igniting the burner in the secondary combustion chamber when the temperature in the outlet stack falls below a predetennined minimum.
  • Apparatus for the destruction of combustible waste material comprising a first incinerator housing enclosing a chamber having a loading port for the charging of waste material therein and an outlet port exhausting the products of combustion therefrom, an airtight closure door for the loading port, a T"shaped outlet duct enclosing a secondary combustion chamber, means connecting a branch of said duct to the outlet port of the first chamber, an outlet stack, means connecting the outlet stack to an essentially vertical branch of said outlet duct, a second incinerator housing having inlet and outlet ports, air supply means connected to the first and second incinerator housings, a single source of air connected to said air supply means, valve means controlling the flow of air through said air supply means to the first and second incinerator housings, temperature responsive means in the out let stack controlling said valve means, and means connecting the outlet port of the second incinerator to an independent branch of said outlet duct whereby the rst and second incinerators are simultaneously connected to the secondary combustion chamber of the
