Definitions

  • the present invention relates to a blown-air burner fed with a liquid fuel, in particular fuel oil, more particularly intended for an application in domestic or industrial heating.
  • a burner is called to perform the mixing of an oxidizer, in this case air, and a fuel, to obtain combustion.
  • an oxidizer in this case air
  • a fuel to obtain combustion.
  • the oil burners comprise a turbine that draws outside air or combustion air to inject it into a circuit and on the other hand means to supply the liquid fuel supply, that is to say in fuel.
  • This fuel is fed by a pump which can be set to maintain a certain supply pressure to ensure the spraying of the fuel.
  • the fuel supply is controlled by one or more solenoid valves.
  • the turbine which supplies the oxidant is actuated by a motor with a constant rotation speed of 2800 revolutions / minute and the air flow is regulated by a shutter which creates a pressure drop in the aeraulic circuit.
  • the pump that supplies the pressurized fuel oil is also driven by a motor that rotates at a constant speed of 2800 rpm, which may be the same as the previous one.
  • Mechanical control means such as valves and pressure regulators, make it possible to adjust the flow rate.
  • the document DE 196 52 205 relates to a single-shaft burner driving both a pump and a turbine, from a constant rotational speed of the motor which is predetermined and fixed at the laying, and under variable air pressure.
  • the present invention proposes to remedy the drawbacks mentioned above by proposing a burner in which the fuel supply pump and the turbine comprise a common drive, coupled to means for modulating the supply of air and fuel oil. .
  • the invention is characterized in that the pump and the turbine are mounted on the same motor shaft, the oil pressure delivered being measured in real time and adjusted if necessary.
  • An associated electronic control then makes it possible to modulate the speed of rotation of the engine, and therefore of the turbine, and to adapt the fuel / oxidant ratio as a function of the measured pressure information.
  • the figure 1 represents the burner according to the invention without showing its implantation environment, which may vary.
  • the burner consists of a burner plate (1) which is connected to a fuel supply circuit via a pipe (2) provided with a solenoid valve (4) connected to a pump (5) which provides fuel oil under pressure.
  • the pump (5) is actuated by a variable speed motor (6), which also controls the air supply means.
  • These means consist of a turbine (7) which is disposed opposite the pump (5) and which is placed inside a volute (3).
  • the pump (5) and the turbine (7) have a common drive.
  • the mechanical connection which results from a common drive makes it possible to ensure a constant ratio between the oil pressure and the air flow, and without it being necessary later to use mechanical correction means.
  • the pump (5) and the turbine (7) are both mounted on the motor shaft (8) of the speed variation motor (6).
  • the shaft (8) therefore drives both the pump (5) which feeds the fuel burner and the turbine (7) which provides the air flow required for combustion.
  • the rotational speed of a turbine engine of a burner of this type is of the order of 2800 revolutions / minute.
  • a drop in engine speed causes a decrease in the oil pressure delivered by the pump.
  • This pressure variation is neither constant nor proportional to the loss of engine speed, and negatively influences the air / fuel ratio, resulting in poor combustion.
  • the solution implemented by the invention is to vary the fuel pressure, that is to say the fuel flow, regardless of the speed of rotation of the engine, so the turbine, c that is to say the flow rate oxidizer, while using a common mechanical drive, which allows to change the air flow without changing the oil pressure.
  • the pump (5) and the variable speed motor (6) are associated with means for modulating the pressure, designed to maintain the pump speed from a certain threshold of motor rotation speed. This predefined threshold of triggering makes it possible to ensure fuel supply in a stable manner.
  • the servocontrol of the oxidant is effected according to the information of the oil pressure and / or of the oxygen value obtained via the modulation means which comprise a measuring device and an associated electronics (10).
  • the measuring device of the modulation means consists of at least one pressure sensor (9) placed at the outlet of the pump (5).
  • the oil pressure delivered by the pump (5) can be readjusted if necessary, according to the information measured and supplied by the sensor (9), which will, if necessary, induce a corresponding variation in the speed of rotation of the motor, therefore the air flow, to optimize combustion.
  • the measuring device of the modulation means consists of at least one oxygen sensor (11) disposed in the combustion chamber, and controlling the fuel pressure and the flow rate. air as a function of the measured 0 2 content.
  • the measuring device of the modulation means combines at least one pressure sensor (9) and at least one oxygen sensor (11).
  • the electronic unit (10) associated with the measuring device indicates in real time and at any time the fuel consumption, and thus makes it possible to control the state of the combustion. We can thus anticipate the maintenance of the burner, and take the necessary security measures in case of bad combustion.
  • the figure 2 shows in the form of a diagram the schematic diagram of the burner according to the present invention, including the exchange of information between the various components of the burner to achieve the object of the invention.
  • the modularity of the air / fuel parameters independently of one another makes it possible to optimize boiler efficiency and combustion hygiene.
  • the air / oil control and the use of oil pressure sensors and / or oxygen sensors allow to modify either the oil pressure, the speed of the turbine or both to compensate for the variations of the air flow rate. for example, in the event of a change in climatic conditions, or variations in the oil flow, for example when the nozzle is dirty.
  • the modulation makes it possible to carry out longer operating cycles (stabilized phase) and thus to avoid many start-up phases (transient phase), which has the advantage of eliminating the losses of output during the phases of meadow. -ventilation, and to avoid electromagnetic disturbances during burner arcing phases.
  • This reduction of the starting phases also makes it possible to reduce the wear of the mechanical parts and thus to increase the service life of the components, to reduce the unburnt and thus to ensure a cleaner combustion and more respectful of the environment.
