Definitions

  • ABSTRACT An incineration system for incinerating flue gases which contain varying quantities of combustibles [52] Cl 23/277 0 0 therein. Means is provided for controlling combustion dd d th fl h tl11 t b 151 int. c1.
  • the other type of fumes contains mainly a mixture of combustibles (hydrocarbons, soot particles, etc.) and other inert gases.
  • the oxygen content of such fumes is relatively small.
  • a source of ignition such as a premix pilot or a burner operating at stoichiometric air/fuel ratio
  • the fume cannot continue to burn because of insufficient oxygen.
  • incinerators are not able to complete combustion of the exhausts; thereby yielding exhaust gases with high quantities of pollutants.
  • FIG. 1 is a vertical cross-sectional view, partially schematic, of an incineration system incorporating the features of this invention.
  • FIG. 2 is a cross-sectional view taken along line 2-2 of FIG. 1.
  • a double chambered system is added to a stack emit ting industrial waste gases which contain various amounts of combustibles therein.
  • the first chamber terminates at the exit end of the stack in an annular passage, or restriction, so that air at high velocity is directed longitudinally relative the stack. This air acts as an air pump to enhance egress of the flue gases.
  • These gases then enter into the second chamber of the housing, which chamber includes a plurality of burners.
  • a thermocouple Within the second housing is a thermocouple which senses the temperature of the waste gases.
  • a preset temperature is achieved by varying the quantities of air emitted from the first chamber as opposed to the amount of fuel and air supplied to the burners in the second chamber. In this way a constant temperature may be maintained despite the variance of combustibles within the exhaust gas.
  • the fume composition, volume and temperature can vary considerably with time.
  • air and fuel supply to the incinerator must be controlled very carefully and independently.
  • an incineration system is shown generally at 10 and is adapted to incinerate exhaust fumes coming from a stack 12.
  • the stack 12 has refractory bricks 14 lined on the inside thereof in order to preserve its heat and, as shown, has its inner wall flared out at its upper end at a shallow angle to its axis to approximately meet with its outer wall.
  • Disposed about and above the stack 12 is a housing 16 having a lower chamber 18 and an upper chamber 20, the housing also being lined with refractory material 21.
  • the lower chamber 18 terminates at the upper end of the stack 12 and has a restricted channel 22 portion.
  • the lower chamber 18 also has an opening 24 therein which receives an air pipe 26.
  • the upper chamber 20 which, as shown, is formed of appreciably wider cross-sectional size than the re stricted channel portion 22 to form within the chamber an upwardly facing flame stabilization shoulder or step located just above the upper end of the stack 12, is supplied with tangential burners 28 that are received within openings 30 in the refractory 21 and are located laterally outward of the exit end of the annular passageway 22 and immediately above the exit end of the stack 112.
  • Gas lines 32 are attached to the burners 28 as are air lines 34.
  • the air lines 26 and 34 are in communication with an air control unit 36.
  • thermocouple 38 Received within the upper portion of the upper chamber 20 is a thermocouple 38 which has a lead 40 communicating with a temperature measuring and recording instrument 42.
  • the temperature measuring instrument 42 in turn has a lead 44 that communicates with the air controller 36.
  • the rich fumes are emitted from the stack 12 into the upper chamber 20.
  • the burners 28 are fired in order to provide the heat of combustion necessary for the exhaust gases.
  • a quantity of air is supplied to the lower chamber 18 from the air line 26 and passes through the channel 22 about the exit end of the stack 12. This air passing through the channel 22 acts as an air pump to aspirate and thereby enhance the discharge, or emission, of the exhaust gases from the stack 12.
  • the annular stream of air from channel 22 promotes uniform mixing of the gases within upper chamber 20.
  • the combustion products will ignite in the upper chamber and the temperature thereof is sensed by thermocouple 38.
  • the measuring instrument 42 will set a given temperature for the combustion products and will control the amount of air supplied to the lower chamber 18 and the upper chamber 20 in response to this temperature.
  • additional air will be supplied to the burners 28 in order to raise the temperature and assures complete incineration of the waste gases.
  • the burners 28 may be of the type that gas is supplied thereto in proportional response to the amount of air supplied to the burners. If the temperature becomes too high, the supply of air to the burners is discontinued and the temperature is controlled by air supplied through the air pipe 26 into the housing 16. So long as the temperature can be maintained at the set point through the supplying of air to the exhaust gases, the burners 28 need not be operated.
  • an incineration system is provided which is operative to completely combust waste gases emitted from a stack, regardless of the amount or percentage of combustibles contained in the gases.
  • an incineration system for exhaust gases emitting from a stack
  • the combination comprising: a housing confluent with and located over the upper portion of the stack, means defining a restricted annular passageway immediately surrounding the exit opening of the stack and confluent with the lower portion of the housing, means for supplying air from the said annular passageway and into said housing to produce an annular stream of air effective through its aspirating action to enhance the egress of the exhaust gases from said stack into said housing and entrain them in said air stream, at least one burner located within said housing adjacent and laterally outward of the exit end of said annular passageway, means for sensing the temperature in said housing, means responsive to said sensing means for controlling the quantity of air from said passageway and controlling the quantity of air and fuel to said burners.
  • an incineration system for exhaust gases emitting from a stack
  • the combination comprising: a housing having an upper chamber, a lower chamber, and a reduced section therebetween of essentially cylindrical form, the stack being received within said housing with its exhaust end located within the reduced section of said housing to define therewith a restricted annular passageway communicating with both said upper and lower chambers and immediately surrounding the exit opening of the stack, means for supplying air to said lower chamber to produce an annular stream of air exiting from said annular passageway into said upper chamber and effective through its aspirating action to enhance the egress of the exhaust gases from said stack into said upper chamber and entrain them in said air stream, burner means located within said upper chamber adjacent and laterally outward of the exit end of said annular passageway, means for sensing the temperature in said upper chamber, and means responsive to said temperature sensing means for controlling said air supply means and said burner means.
  • said burner means comprises a plurality of burners located adjacent and laterally outward of the exit end of said annular passageway with their longitudinal axes directed generally tangentially relative to the stack.
  • An incinerator for exhaust gases emitting from a stack and containing combustibles but insufficient oxygen to support the substantially complete combustion thereof, said incinerator comprising a housing having an upper chamber, a lower chamber, and a reduced passageway section therebetween of essentially cylindrical form, the stack being received within said housing with its exhaust end located within the reduced passageway section of said housing to define therewith a restricted annular passageway communicating with both said upper and lower chambers and immediately surrounding the exit opening of the stack, means for supplying air to said lower chamber to produce an annular stream of air exiting from said annular passageway into said upper chamber and effective through its aspirating action to enhance the egress of the exhaust gases from said stack into said upper chamber and entrain them in said air stream, an upwardly facing lateral shoulder in said upper chamber forming the lower end thereof and located immediately above and surrounding the exit end of said stack for stabilizing thereat the flame of the burning exhaust gases in the upper housing, and burner means in said upper housing located adjacent and laterally outward of the exit end of said annular passage
  • burner means comprises a plurality of burners located with their longitudinal axes directed generally tangentially relative to the stack.
