Definitions

  • the present invention is an instant steam generator.
  • the invention provides a compact unit having no boiler which can be used on site to generate various qualities of steam for a variety of applications.
  • the invention has particular application for curing prestressed and precast concrete and generally for the standard curing of concrete products such as blocks or pipes.
  • the concrete curing process generates heat, which tends to warm up the inside of concrete products.
  • a desirable feature for an instant steam generator is that is has a low carbon monoxide output.
  • a low carbon monoxide output is essential where the steam generator is operated in an enclosed facility, for example, in a concrete products plant or in a mine, in order to meet typical government regulations for worker exposure to carbon monoxide.
  • the invention employs a unique combustion chamber and water vaporization combination whereby the combustion chamber is cooled by a surrounding jacket of circulating water, and the outflow of water from the jacket is used as the source of water to be vaporized by combustion gases from a burner located at one end of the chamber.
  • the present arrangement differs from that previously known, for example as described in U.S. Patent No. 4,211,071-­Wyatt, July 8, 1980, by introducing a spray of water countercurrently to the stream of combustion gases exiting the combustion chamber. This arrangement creates a great deal of turbulence in the area surrounding the water spray thus ensuring instant and thorough vaporization of the spray by the combustion gases.
  • prior devices e.g.
  • a steam generator comprising a water jacketed combustion chamber having an inlet and an outlet for the circulation of water through the jacket and having first and second ends.
  • a burner is positioned in the first end of the combustion chamber.
  • Means are provided for delivering pressurized air and fuel to the burner so that the burner may produce a flame extending toward the second end of the combustion chamber.
  • a water spray nozzle is positioned at the second end of the combustion chamber remote from the burner flame, said nozzle being connected to the outlet of the jacket and being adapted to spray water countercurrently into a stream of hot gases from the burner flame thereby creating steam without quenching the flame.
  • a discharge conduit is connected to the second end of the combustion chamber for conveying the steam so generated.
  • the present invention employs a unique arrangement in which the water is sprayed countercurrently to the flow of hot gases, and the water spray nozzle can be pointed directly at the burner.
  • This arrangement is contrary to conventional teachings which specify that the water should be sprayed away from the flame to avoid flame quenching.
  • the steam generator of the present invention comprises a combustion chamber 10 having a burner 11 at one end and a water spray nozzle 12 at the other end.
  • the chamber 10 is provided with a water jacket 15 (Fig. 2) having a jacket inlet 16 near the lower end of the chamber 10 and a jacket outlet 17 near the upper or burner end of the chamber 10.
  • Water is circulated throught the jacket 15 at a rate of circulation governed by water pressure controls 19 which are readily available and which are inserted into the water inlet line 20.
  • Water exiting the jacket 15 proceeds through the jacket outlet 17 and a pipe 22 to the water spray nozzle 12 which is in turn located within a steam outlet line or discharge conduit 24.
  • the combustion chamber 10 is sized to enable complete combustion of the fuel by the flame of the burner 11 within the confines of the chamber 10.
  • a zone 25 in the lower portion ofthe combustion chamber 10 for the hot exhaust gases of combustion with fuel combustion occurring to the fullest extent allowed by the mechanics of the burner 11 in a zone 26 in the upper portion of the chamber 10 about the flame.
  • the burner 11 is an oil burner or preferably a burner of the type which burns a pressurized gaseous fuel mixture such as air and natural gas or propane. Accordingly, the burner 11 is provided with an inlet conduit 30 comprising a larger diameter inlet air pipe 31 for pressurized air, into which is joined a fuel pipe 32 of a lesser diameter. The junction point 33 of the pipes 31 and 32 is just upstream of a venturi 35. The gaseous fuel mixture is throughly mixed by flowing through the venturi 35 thereby ensuring even combustion at the burner head 11 and affording good control of the heat output therefrom.
  • a pressurized gaseous fuel mixture such as air and natural gas or propane. Accordingly, the burner 11 is provided with an inlet conduit 30 comprising a larger diameter inlet air pipe 31 for pressurized air, into which is joined a fuel pipe 32 of a lesser diameter.
  • the junction point 33 of the pipes 31 and 32 is just upstream of a venturi 35.
  • the gaseous fuel mixture is throughly mixed by flowing through the venturi 35
  • the air supplied to the inlet air pipe 31 is pressurized in a conventional manner by drawing air in through a filter 40 and passing it through a blower 41 or other well known compression means.
  • Pressure in the inlet air pipe 31 may be regulated by use of an appropriate air pressure valve 42, and pressure in the fuel pipe 32 may be controlled by a conventional fuel valve 43.
  • the valves 42 and 43 By adjustment of the valves 42 and 43, the pressure and composition of the fuel mixture can be varied as desired.
  • Ignition of the burner 11 may conveniently be accomplished by use of a pilot 49 located adjacent the head of the burner 11.
  • the pilot 49 may receive a fuel mixture from feeder lines 50 and 51 taken from the main fuel pipe 32 and the inlet air pipe 31.
  • the feeder lines 50 and 51 tap the main pipes 31 and 32 at points upstream of the respective valves 42 and 43.
  • the feeder lines 50 and 51 are also provided with valves 53 and 54 so that the desired combustion gas mixture and pressure can be provided to the pilot 49.
  • any of a number of different kinds of burners would be suitable for use in the present invention. Since the steam generated by the present device contains the exhaust from the burner 11, it may be particularly desirable in certain applications to choose a burner 11 which produces a low level of carbon monoxide. The low carbon monoxide level of the burner 11 will be retained during the steam generating process using the present device, because there is no flame quenching produced by the contercurrent spray of water from the nozzle 12. Likewise, the foregoing description of the fuel and air supply means is illustrative and may be varied with the type of burner used. It will also be apparent to those skilled in this art that central control means may be employed to coordinate the flows and relative pressures of the fuel, air and water streams for the overall system.
  • steam is generated by the mixture of the water spray from the water spray nozzle 12 with the hot combustion gases produced by the burner 11 at the lower end of the combustion chamber 10.
  • the spray from the water spray nozzle 12 By causing the spray from the water spray nozzle 12 to be directed countercurrently to the exhaust gases from the burner 11, instant vaporization of the water occurs due to the extreme turbulence and thorough mixing of the opposing streams. Turbulence and mixing of opposing streams may be modified by the insertion of baffles in the combustion chamber 10 and in the steam outlet line 24. The quality of the steam exiting through the steam outlet line 24 may be determined by adjusting the output of the burner 11 and the output of the water spray nozzle 12.
  • the relative opposing pressures from the burner 11 and the spray nozzle 12 must be adjusted to enable steam to be generated in the manner described, that is, by vaporization of the water contacting the hot exhaust gases from the burner 11.
  • the generation of relatively low pressure steam i.e. 5-20 psi, is accomplished using the invention wherein the water vaporization occurs virtually entirely within the outlet neck 59 located between the lower end of the combustion chamber 11 and the steam outlet line 24.
