Definitions

  • tion of the flow of hot flue gases is controlled by aerodynamic valving rather than by mechanical means through either the main stack or the auxiliary stack provided with the heat exchanger of a heat recovery apparatus.
  • the present invention relates to a new and improved system or apparatus for controlling the direction of flow of hot flue gases through either a main stack or an auxiliary stack having heat exchanger means therein for recovery of waste heat. More specifically, the invention is intended for use with an incinerator for burning waste material, either solid or liquid or a combination, although the apparatus may be used with other types of equipment producing flue gases such as a furnace, a gas heater, or the like.
  • incinerators which utilize a two-stage combustion process for producing clean flue gases.
  • burning of the bulk of the waste material is accomplished in a first combustion chamber.
  • This type of incinerator is a controlled air flow type which produces a constant discharge of clean flue gases without adjustment of its controls.
  • steam When steam is generated, it may be used in plants such as hospitals, textile mills, or the like, as an auxiliary system, or for that matter, the main system for supplying steam for various purposes.
  • the recovery system if it is used for hot water, it may be used in situations where hot water heat is desired; for example, in heating a building, providing hot water for hot water distribution systems in a building, and the like.
  • a further system proposed was the provision of a heat exchanger for a heat recovery system in the main exhaust stack, but such a system was also not practical as there were oftentimes periods when the heat recovery apparatus did not have to be used while the incinerator was in use and this in and of itself was undesirable since it could create a hazardous condition in the heat recovery apparatus. Additionally, the system was costly as the main stack had to have a continuously operating fan therein to overcome the pressure drop across the heat exchanger and maintain an adequate forced draft in the combustion chamber regardless of whether theheat recovery apparatus was operating.
  • a third system proposed involved the use of a main stack and a separate auxiliary stack, both connected to the combustion chamber.
  • the main stack had a mechanically operated butterfly valve therein to close off flow when it was desired to utilize the auxiliary stack containing the heat exchanger of the heat recovery apparatus.
  • the auxiliary stack also had a mechanically operated butterfly valve therein which was closed when the heat recovery system was not in use.
  • the butterfly valve in the main stack was normally linked by a common control device to the butterfly valve in the auxiliary stack, but both of these valves had to be made of special refractory material as they were exposed to hot flue gases. This made such a system economically unsatisfactory.
  • the present invention is an improvement over the above described prior efforts in that it provides an aerodynamic valving system for directing flue gases through either a main stack or an auxiliary stack opening to the main stack and having a heat exchanger therein of a heat recovery apparatus.
  • an aerodynamic valving system By utilizing an aerodynamic valving system, movable valve parts or elements are not provided in the flow path of the hot flue gases at anytime and a desired constant draft and flow condition can be maintained in the combustion chambers of the incinerators so that the flue gases are at all times substantially pollution free.
  • the directional control apparatus for the flue gases comprises providing a combustion zone delivering pollution free gases with a main stack so that such gases can normally flow to atmosphere and an auxiliary stack defined by a conduit having a first portion and a second portion.
  • the first portion extends transversely to the axis of the main stack and opens to the same at a position downstream from the combustion zone, but in an area where the temperature of the flue gases is in the order of 1200 to 2400F.
  • the first portion of the conduit is provided with a heat exchanger of a heat recovery apparatus and is connected to the second portion which discharges flue gases after heat has been recovered therefrom.
  • the aerodynamic valving system includes an air blower having its outlet connected to a manifold, the manifold being respectively connected to a first means for discharging an air jet downstream of the heat exchanger and in a downstream direction and a second means for discharging an air jet into the main stack above the point of connection of the first portion of the conduit to the main stack and also in a downstream direction of the main stack.
  • the system provides a fail-safe means at times of dangerous or emergency conditions arising in the heat recovery apparatus because the blower can be turned off by a sensing unit for sensing an over capacity within the heat recovery apparatus. Once the blower is turned off, the pressure loss across the heat exchanger will cause the flue gases to take the path of at least resistance, namely, upwardly through the main stack so as to be discharged to atmosphere therefrom. The auxiliary stack and the heat exchanger will then cool down.
  • the fail-safe feature is inherent in the operation of the blower and should the blower itself fail for any reason, the flue gases will immediately be diverted from the auxiliary stack and pass upwardly and harmlessly out of the main stack.
  • FIG. I is a side elevational view of the directional control apparatus and incinerator of the present invention, the view being primarily diagrammatic and partly in section.
  • FIG. 2 is an enlarged vertical sectional view of the adapter member for the main stack and illustrates the manifold for supplying air jets to the main stack.
  • FIG. 3 is an enlarged view looking in the direction of the arrow A of FIG. 1, but illustrating a manually adjustable splitter valve for splitting and proportioning air from the air blower and delivering it respectively to the main stack and auxiliary stack.
  • FIG. 4 is a fragmentary top plan view of FIG. 3.
  • FIG. 5 is a diagrammatic fragmentary end view of the main stack and auxiliary stack arrangement shown in FIG. 1 and looking generally from the left to the right of FIG. 1.
  • FIG. 6 is a diagrammatic end view similar to FIG. 5, but disclosing a modified form of the invention wherein inlet air to the blower is modulated in accordance with conditions in the heat recovery tank.
  • an incinerator for the present invention is generally designated by the reference numeral 10.
  • the incinerator 10 includes an annular casing 12 provided with suitable refractory lining, the ends of the casing being provided with doors 14 and 16 or suitable mechanical means for loading and unloading the same.
  • the casing 12 preferably has a horizontal axis, such as shown in the aforementioned Pat. No. 3,489,109, although it may have a vertical axis, such as shown in the incinerator of Pat. No. 3,403,645.
  • Casing 12 provides a main combustion zone or chamber 18 for the burning of waste material and the casing includes the usual pressure burners 20 having nozzles within the chamber for starting the burning process of the waste material.
  • the bruners 20 normally are turned off once combustion has started and operating temperatures are reached.
  • air is supplied in controlled amounts to the main combustion chamber 18 to assist in supporting combustion once the waste material is burning.
  • Incinerator 10 further includes a transition conduit 22 defining a second combustion chamber or zone 24, the transition conduit 22 being in communication with a passageway 26 in the upper portion of the casing 12.
  • Hot exhaust gases from the main combustion zone chamber 18 pass through the passageway 26 into the second combustion zone 24 where a secondary stage of burning is accomplished.
  • the exhaust gases leaving the main combustion zone carry with them burnable pollution particles or products which must be removed so that the resulting flue gases are substantially pollution free.
  • a pressure burner 28 having its nozzle 30 in the second combustion zone 24 is provided, as well as an air blower 32, which discharges air into this zone to assist in the supporting of the combustion process.
  • the pressure burner 28 may be cut off as the air supplied to the combustion zone or chamber 24, plus the heat of the exhaust gases is sufficient to support complete burning of waste products and the production of substantially pollution free flue gases.
  • the second combustion chamber 24 is provided with a discharge opening 34 to which is attached a main stack assembly 36.
  • a main stack assembly 36 Under normal conditions of operation, the substantially pollution free flue gases will flow straight up the main stack 36 and be discharged from its upper end 38 to atmosphere.
  • the main stack 36 is provided with a side opening 40 spaced upwardly from the combustion chamber 24, but
  • An auxiliary stack generally designated at 42 is connected to the opening.
  • the auxiliary stack 42 is a conduit having a first portion 44 with a substantially horizontal axis transverse to the axis of the main stack 36, the first portion 44 being connected at one end to the opening 40.
  • a second portion 46 of the auxiliary stack or conduit 42 is connected at its lower end to the outer end of the first portion 44 and it extends upwardly for discharging flue gases therefrom when such gases are flowing through the auxiliary stack 42, as will be described in more detail later in the specification.
  • a heat recovery apparatus generally designated at 48 includes a steam tank 50 and a heat exchanger 52 positioned in the first portion of the auxiliary stack or conduit 42.
  • the steam tank 50 is provided with a water inlet 54 through which water is supplied when necessary and a steam outlet 56 from which steam is supplied upon demand to a source of use, such as a hospital steam system or a textile plant steam system.
  • the heat exchanger 52 has been diagrammatically shown as a plurality of coils having a water inlet 58 from the steam tank 50 and a steam outlet 60 to the steam tank 50.
  • the usual pressure gauge 62 and safety valve 64 are provided on the steam tank 50. While the heat recovery apparatus has been described as a steam system, it, of course, could be a hot water system for supplying hot water to a point of use or a system for heating other transfer fluids.
  • an air jet is also discharged into the main stack 36 above the opening 40 in a downstream direction merely to prevent air from being sucked down the main stack and cool the hot flue gases flowing through the auxiliary stack 42.
  • an air blower 66 having a source of power such as a five horsepower motor 68, is utilized.
  • the air blower 66 had a suitable adjustable inlet valve 70 to control the amount of discharge from its air outlet and a motor control means 72 for starting and stopping the motor.
  • the air outlet of the blower 66 is connected to a manifold 74 which, in turn, is connected to a first duct 76 and a second duct 78.
  • the first duct 76 extends into the second portion 46 of the conduit or auxiliary stack 42 and centrally upwardly therein and terminates in an air jet nozzle 80.
  • the second duct 78 also extends from the manifold 74 at a position adjacent to the connection of duct 76 to an adapter member 82 (FIG. 2) positioned in and forming a part of the main stack 36 just above the opening 40.
  • the adapter member 82 includes a metallic shell 84 having a refractory liner 86, the shell also having an annular manifold 88 at its upper end for receiving the air from the air duct 78.
  • a plurality of holes 90 communicating at one end with the manifold 88 and extending upwardly through the refractory material 86 open to the interior of the adapter member 82, as indicated at 92.
  • the openings 92 define small jet nozzles for discharging air upwardly in the main stack 36 to prevent cold air from being sucked down the main stack when the auxiliary stack 42 is being used.
  • a splitter valve generally designated at 94 is provided at the junction of the ducts 76 and 78 with the manifold 74.
  • a curved baffle or wall 96 extends between the openings of the ducts 76 and 78 to the manifold.
  • the splitter valve 94 includes a flat plate 98 pivoted on a pivot axis 100 at the end of the baffle 96.
  • the pivot axis includes a pivot rod 102 fixed to the plate 98, the rod extending outwardly of the manifold 74.
  • a pointer arm 104 fixed to the rod 102 shows the position of the plate member 98.
  • the pointer arm 104 has an elongated slot 106 therein through which a projection 110 of a threaded sleeve nut or collar (not shown) extends.
  • the sleeve nut or collar is threadedly received on a screw 112 and rotation of the screw 112 causes the sleeve nut to move up or down, thus varying the pointer arm 104 and pivoting the pivot rod 102 which fixedly carries the plate member 98.
  • the screw 112 is connected to a motor 114 for automatically rotating the same in one direction or the other.
  • the motor in turn is provided with a motor controller unit 116, the motor controller being connected to sensor member 118 on the steam tank 50.
  • the sensor member 118 may be of the type that detects the pressure in the steam tank or the temperature of the heated fluid and, thus, when it sends a signal to the controller 116, it will cause the splitter valve 94 to be operated in one direction or the other, depending upon the sensed condition so as to modulate the flow of flue gases through the heat exchanger 52.
  • the sensor member 118 indicates that the steam tank 50 of the heat recovery apparatus 48 is low in steam pressure available for use, it will send a signal to the controller to move the splitter valve to a position wherein more air is discharged from the nozzle 80, thus drawing more hot flue gases across the coils of the heat exchanger 52 to develop more steam. If the steam pressure in the tank builds back up to a level greater than desired, the splitter valve 94 will be moved in an opposite direction so as to cause the pumping action of the nozzle 80 to decrease, thus permitting some of the flue gases to flow upwardly in the main stack 36 until such time as the demand for more steam requires more of the flue gases to flow through the auxiliary stack 42.
  • the adjustable air inlet valve 70 is preset to give a constant output of air to the manifold 74 when the blower 66 is operating.
  • a fail-safe sensor member 120 is provided on the steam tank 50 for detecting emergency conditions within the tank, such as over pressure or low water level.
  • the failsafe sensor member 120 is connected to the motor controller 72 of the blower motor 68 and once it is activated, it immediately cuts off the blower motor and this stops all pumping action of the aspirating air jets in both the main stack 36 and the auxiliary stack 42.
  • the hot flue gases discharged from the combustion chamber 24 will no longer be able to go through the heat exchanger 52 and they will taken the path of least resistance and go straight up the main stack 36 and be discharged to atmosphere. In fact, this action will actually draw some air into the main stack from the auxiliary stack, cooling the heat exchanger.
  • FIG. 6 there is an alternate modification shown for modulating the aspirating action of the air jet nozzles 80 and 92.
  • the splitter valve 94 is manually adjusted by providing a crank handle 124 on the screw 112 (FIGS. 3 and 4).
  • the pumping output energy of the blower 66 is varied by connecting the air inlet valve 70 to a controller 126, the controller in turn being connected to a sensor memher 128 on the tank 50.
  • the sensor member 128 may be similar to the sensor member 118 so that it senses the conditions within the tank as to whether or not more steam is needed. If more steam is needed, the air inlet valve 70 is opened more by the controller 126, thus providing a greater output of air from the blower 66 to the manifold 74.
  • the second portion 46 of the auxiliary stack or conduit 42 may be folded back and coupled into the main stack to discharge flue gases therefrom when the flue gases are passing through the auxiliary stack system.
  • the opening of the second portion 46 into the main stack 36 must be downstream of the adapter member 82 and its aspirating air jet nozzles 92.
  • an incinerator In a system such as described above where an incinerator has a capacity of disposing 1000 pounds per hour of all types of hospital waste, such an incinerator produces up to 5 or 6 million BTUs per hour in the flue gases.
  • the system has its heat recovery apparatus connected into the normal steam system of the hospital, it can reduce the fuel for the normal system as this auxiliary system will produce as much as 2500 to 3000 pounds of steam per hour at pounds per square inch gauge.
  • the inlet temperature of the flue gases into the heat exchanger is about 1800F., whereas the outlet temperature from the heat exchanger is about 725F., thus realizing over 60 percent recovery of heat energy from the flue gases.
  • the static pressure in the upper burner chamber 24 is maintained constant to about .15 inch water gauge.
  • a directional control apparatus for flue gases received from a combustion zone comprising: an upwardly extending stack operatively communicating with the combustion zone and normally aspirating flue gases therefrom to atmosphere; a conduit having a first portion extending transversely to the axis of said stack and opening to said stack and a second portion for discharging flue gases diverted from said stack through said first portion; heat recovery means including heat exchanger means in said first portion of said conduit for recovery of heat from flue gases; and aerodynamic valving means to divert gases from aspirating upwardly and discharging from said stack to go through and discharge from said conduit whereby said heat exchanger means removes heat from said flue gases, said aerodynamic valving means including a first means for discharging an air jet into said conduit in a downstream direction of said conduit, said first means being positioned downstream of said heat exchanger means and a second means for discharging air in a downstream direction in said stack, said second means being positioned downstream of the opening of said first portion of said conduit to said stack.
