Definitions

  • ABSTRACT [22] Filed: May 12, 1972 A steam generating system comprising burning fuel which contains no sulphur or nitrogen in an atmol l PP 1 sphere of pure oxygen to heat water in a heat exchanger for converting water to steam.
  • the fuel which contains no sulphur or nitrogen in an atmol l PP 1 sphere of pure oxygen to heat water in a heat exchanger for converting water to steam.
  • Prior Art Steam generators have long been used to produce steam for heating, driving turbines and generators, providing motive power for locomotives and automobiles, and other purposes.
  • the steam generators of the prior art have generally employed combustion chambers wherein fuel was burned in air at relatively low pressures of the order of to psia, and have required relatively massive heat exchange units or boilers, often 40 to 60 feet in length and 20 to 60 feet in diameter, to produce steam.
  • steam generators often provide incomplete combustion of the fuelair mixture and the products of such incomplete combustion have conventionally been released to pollute the atmosphere.
  • these problems have been overcome by employing a system wherein a hydrocarbon fuel is burned in an oxygen atmosphere and the products of combustion are used directly to drive a turbine or the like.
  • these products of combustion include carbonic acid and other generally noncondensible gases such as hydrogen, carbon monoxide, and carbon dioxide, which, in gaseous form, are less efficient than steam in driving the turbine, tend to attack and corrode the turbine blades, and which cannot be recycled, as in the case of pure steam.
  • the advantages of the present invention are preferably attained by providing a steam generator which em ploys separate heat producing and steam producing systems.
  • air is excluded and liquid or gaseous oxygen is employed as an oxidizer for a fuel containing no sulphur or nitrogen, such as liquid natural gas.
  • the liquid oxygen and fuel are raised to high pressure and vaporized into a gaseous state prior to combustion.
  • the hot products of complete combustion are passed through a heat exchanger to convert water to steam in the separate steam producing system and may, then, be exhausted into the atmosphere without pollution.
  • the products of this combustion will contain only water, carbon dioxide and carbonic acid, which quickly dissociates into water and carbon dioxide. Hence, the exhaust contains no pollutant material.
  • the separate water of the steam producing system is isolated from the carbonic acid and non-condensibles.
  • the efficiency of the steam is preserved and the turbines are protected against corrosion.
  • the oxygen and fuel may be mixed and burned at pressures of up to several thousand pounds per square inch. This produces extremely rapid combustion which converts water to steam much more quickly and permits the size of the heat exchange unit to be vastly reduced which, in turn, greatly simplifies servicing and installation.
  • Another object of the present invention is to provide an improved method of operating steam generators.
  • a further object of the present invention is to provide a steam generator which will not discharge pollutants into the atmosphere and yet will protect turbines, condensers, and the like against corrosion and noncondensibles.
  • An additional object of the present invention is to provide a steam generator which is extremely compact.
  • Another object of the present invention is to provide a steam generator which is simple to install and service.
  • a specific object of the present invention is to provide a steam generator comprising a source of an oxidizer containing no nitrogen, a source of fuel containing no sulphur or nitrogen, a combustion chamber, a closed system for deliverying said oxidizer and said fuel to said combustion chamber, a source of water connected to supply water to said heat exchanger, and output means for delivering steam from said heat exchanger to a utilizing device.
  • the FIGURE is a diagrammatic representation of a steam generating system embodying the present invention.
  • FIGURE shows a steam generator, indicated generally at 2, having a combustion chamber 4 and a heat exchanger 6.
  • a pair of storage tanks 8 and 10 are provided and tank 8 is filled with a liquid.
  • oxidizer such as oxygen (0, O or hydrogen peroxide
  • tank is filled with fuel.
  • oxidizer such as oxygen (0, O or hydrogen peroxide
  • fuel any type of fuel may be employed However, it is imperative that the fuel contains no sulphur or nitrogen.
  • liquefied methane natural gas is a preferred fuel, although other fuels such as hydrogen, ethane, propane, alcohol, etc., may be used.
  • the oxygen and fuel are conducted to the combustion chamber 4 by a delivery system indicated generally at 12, which is closed to prevent air from contaminating the fuel or oxygen.
  • the liquid oxygen is drawn from the storage tank 8, through a suitable flow control device 14, by a pump 16 and is passed to a vaporizer 18, where the liquid oxygen is expanded to a gaseous state.
  • the gaseous oxygen is then conducted through conduit 20 and flow control device 22 to a pressure regulator 24 and is passed through an additional flow control device 26, such as a sonic or cavitating fluid venturi nozzle, to the combustion chamber 4.
  • the liquid fuel is drawn from storage tank 10, through a suitable flow control device 28, by pump and is passed to vaporizer 32, where it is expanded to a gaseous state.
  • the gaseous fuel is then conducted through conduit 34 and flow control device 36 to a temperature controller 38 and is passed through an additional flow control device 40 to the combustion chamber 4.
  • pressure sensing transducers 42 and 44 are connected to the respective conduits; as shown, and supply signals, indicative of the respective pressures, to a differential pressure controller 46 which compares these signals and serves to control the pressure regulator 24 to automatically maintain the desired pressure ratio between the fuel and oxygen.
  • the oxygen and fuel are ignited by a suitable igniter, as seen at 48, and the burning gases are passed through the central circular tube or other geometric gas passage 50 of heat exchanger 6.
  • a suitable igniter as seen at 48
  • additional oxygen may be passed through conduit 52, flow control device 54, and manifold 56, and introduced to the burning gases at 58, adjacent the entry to tube or passage 50 of the heat exchanger 6 to increase the temperature of the gases.
  • the initial combustion of the oxygen-fuel mixture may occur at 58.
  • secondary fluid such as water from a suitable source, not shown
  • secondary fluid such as water from a suitable source, not shown
  • water is supplied through pipe 60 and inlet manifold 62 to the jacket 64 of the heat exchanger 6 and is conducted in heat exchanging relation with hot gases in the central gas passage 50, the water being converted into steam by the time it passes out through outlet manifold 66.
  • Steam then passes through conduit 68 to a utilizing device, not shown, such as a turbine other suitable means.
  • the water supplied to pipe 60 is first passed through an exhaust condenser 70 from inlet 61 in heat exchanging relation with the exhaust gases from the central tube 50 of the heat exchanger 6. This serves, simultaneously to cool the exhaust gases from the heat exchanger 6, to improve efficiency, and to preheat the water supplied to the pipe 60.
  • the overall recovery of combustion gas enthalpy can be of the order of 4,000 Btu per pound, or greater.
  • the combustion chamber 4 and heat exchanger 6 may be formed of conventional high temperature metals, such as steel alloyed with nickel, chromium, cobalt, or nickel or copper alloys such as BeCu, Cu, Ag-Cu, or a combination of these, or can be lined with a conventional refractory material, such as molybdenum, tungsten, tantalum, or the like, for high steam temperatures.
  • a conventional refractory material such as molybdenum, tungsten, tantalum, or the like, for high steam temperatures.
  • the configuration and relationship of the combustion chamber 4 and heat exchanger 6 may be made substantially as desired, provided that the ratio of the combustion gas passage length to the hydraulic diameter (gas flow area to wetted perimeter rates, multiplied by four) is large, preferably greater than and less than 1000, on the gas side.
  • the flow direction of the secondary fluid may be substantially as desired and will be determined by the specific use of each installation.
  • the liquid fuel and oxygen from storage tanks 8 and 10, are raised to high pressure states and are supplied to the combustion chamber 4, where they are ignited at 48, or at 58.
  • the gaseous fuel and oxygen are supplied to the combustion chamber 4 under pressure since it has been found that this results in more rapid combustion when the gases are ignited.
  • This provides for more efficient conversion of water to steam, and, hence, permits the size of the heat exchanger to be reduced. Obviously, the greater the pressure of the gases at ignition, the more this result will be obtained.
  • the burning gases are passed through the heat exchanger 6 and additional oxygen can be added to further increase the temperature of the flame.
  • the fuel must not contain sulphur or nitrogen, as it is these elements which combine with other elements in the exhaust to produce pollutants. Moreover, by using pure oxygen with this fuel in a closed delivery system, the nitrogen contained in atmospheric air is excluded.
  • the exhaust from the steam generating system of the present invention will consist only of water, carbon dioxide and carbonic acid, which rapidly dissociates into water and carbon dioxide.
  • the efficiency of the steam is preserved and the carbonic acid and non-condensible carbon dioxide are kept out of the steam and, hence, cannot attack and corrode turbine blades and the like.
  • the fuel and oxygen could be stored in gaseous, rather than liquid form.
  • solid fuels could be employed, provided they contain no sulphur or nitrogen and are stored and delivered to the combustion chamber in a manner which excludes air.
  • other secondary heat exchanging fluids such as liquid metal, organic fluid, carbon dioxide, mercury, or the like, may be employed as intermediate heat exchanging fluids between the hot combustion gases and the water.
  • a steam generating system comprising:
  • a closed delivery system connected to deliver said oxidizer and said fuel to said combustion chamber under pressure
  • a heat exchanger connected to receive heat from said combustion chamber on one side of a heat exchanger wall
