Definitions

  • the present invention relates to an apparatus intended to improve combustion in burners operating on the basis of gaseous, liquid or solid elements.
  • the object of the invention is the elimination of air pollution and fuel economy.
  • burners are already known for spraying by means of water vapor; in these devices the vaporized water is brought into the ignited fuel.
  • An apparatus according to the invention is characterized in that it continuously supplies an air-water mixture at low temperature to the burner.
  • the water is in the liquid state, in microdrops from 20 microns to 70 microns in diameter suspended in an air atmosphere.
  • the suction of air from the burner is used as transport.
  • An apparatus produced in accordance with the invention comprises a non-hermetic reservoir containing a body of water surmounted by a vaporization chamber with an inlet for pressurized air and an air-water outlet, said reser see containing a heating means for the mass of water to be vaporized and said air-water outlet being intended to be connected to the air intake of a boiler burner.
  • the principle on which the device is based is the vaporization at low temperature of a body of water, at a fixed temperature, at atmospheric pressure and in a non-hermetic tank.
  • FIG. 1 schematically represents a reservoir 1 with a body of water 2 at a temperature T O and a vaporization chamber 3. With these elements the law of vaporization at low temperature, at constant temperature and at atmospheric pressure can be accomplished .
  • the apparatus according to the invention consists (FIG. 2) of the reservoir 1 of variable shape, for example here parallelelipipedic, non-hermetic with one or more air inlets 4 and an air-water outlet 5.
  • the dimensions of the tank and the outlet depend on the air-water quantities required.
  • the lower part of the tank contains a body of water 2 at a determined level.
  • the device is equipped with an automatic water supply system from the outside (not shown) and a level maintenance system.
  • 'water 6 floats, electronic sensors, etc.
  • the end of the water supply hose is slightly bent downwards inside the tank in order to prevent the jet of water from causing turbulence in the mass of liquid during feeding.
  • the appliance is fitted with an overflow 7 to avoid damaging the electrical parts in the event of a failure in the water supply system.
  • the vaporization chamber 3 is separated by several metal partitions 8, allowing more efficient scanning of the accumulated air-water quantity.
  • the rear upper part of this chamber 3 is designed so that metal partitions 9 direct the gaseous mass (air-water) towards the outlet pipe 5.
  • blower system 10 allowing air to be pulsed, such as a motor-fan or any other system.
  • stainless steel is advantageously used.
  • the tank 1 In the bottom of the tank 1 there are one or more pipes 11 depending on the power of the device. They serve as receptacles for one or more electrical resistances or any other source of controlled heat.
  • the electric resistors are connected to a thermostat, which regulates the temperature of the liquid mass. This temperature oscillates between 40 ° C. and 60 ° C., depending on the air-water quantities which it is desired to produce with the same mass-water volume unit.
  • a tube 12 for the placement of the thermostat.
  • This tube is slightly inclined and filled with oil, which conducts heat, to improve the contact of the thermostat bulb making it more sensitive to thermal variations in the body of water.
  • the tank 1 In order to maintain the air temperature, contained in the tank 1 (70 ° C maximum) it is thermally insulated. The insulation placed on the outside of the tank is covered with a protective sheet, painted or plasticized.
  • the electrical part is made up of a general switch for the power supply of the device and a light signal.
  • the switch feeds the heating resistance (s) of the water body (resistance adjusted through the thermostat) and an electronic level probe, which controls the opening of an electrovalve for the water supply to the appliance. .
  • the thermostat In smaller devices the thermostat is connected in series with the resistors and in more devices large the thermostat controls a contactor which, in turn, triggers the start of the resistor or resistors.
  • the electronic level sensor acts by means of two stainless steel rods, which determine the maximum and minimum levels of water, the difference being established between 8 mm and 10 mm.
  • the starting of the motor-fan 10 is triggered by an auxiliary circuit, which has itself been triggered by the fuel oil solenoid valve, for example, from the burner.
  • the device then delivers the requested air-water quantity.
  • This parallel connection between the burner supply solenoid valve and the unit's fan motor is essential to prevent the latter from outputting when the boiler burner is stopped.
  • the air inlet opening 4 is equipped with a closing valve 4 ', inclined and pivoting, which opens by the thrust of the air forced by the motor-fan and which closes by its own weight , when said motor-fan is stopped, thus avoiding the air flow between inlet and outlet, which could possibly alter the working cycle.
  • the device comprises a chassis 15 provided with two reinforcement profiles 16, on which the assembly is supported (tank, electrical bolt, cover sheet).
  • This chassis can be fitted with casters.
  • the device according to the invention is placed so as to connect the air-water outlet 5 to the air intake 17 of the burner 18. Between the device and the burner there must be a minimum distance A of 150 mm ( Figure 4 ). This spacing between the air-water outlet and the burner air intake is essential to prevent the condensed water - if the burner stops working for some time - in the outlet pipe from being drawn into the burner, which could humidify the ignition system. Instead of being connected to the burner air intake as in the drawing, the air-water outlet can be connected to the burner fan.
  • the appliance cannot be placed near the burner, extend the air-water outlet with a rigid or flexible pipe and connect it to the burner air intake.
  • the unit's fan motor automatically supplies the necessary quantity of air-water. Since the air-water mass exits through a pipe of reduced diameter, it expands when it leaves the atmosphere and consequently cools. At this time, it is sucked in by the air flow from the burner fan, which cools it further, and it arrives at the combustion chamber in liquid state, which allows it to accomplish its mission.
