Definitions

  • the invention relates to a device on a heating system with a boiler with a combustion chamber into which a burner protrudes and which is surrounded by a double jacket which is provided with an inlet and an outlet and through which the fluid to be heated flows is.
  • the aim of the invention is to avoid these disadvantages and to propose a device of the type mentioned at the outset which is distinguished by a particularly high degree of efficiency and in which sooting is largely avoided.
  • the fluid supplied to the double jacket is preheated before it flows into it by the direct action of the flame of the burner, whereby there is no fear of fouling in the area of the register due to the heat of the flame and no reduction in the air throughput through the combustion chamber occurs.
  • the runtime of the burner is considerably shortened, which results in energy savings.
  • the lines connecting the two collectors of the register are formed by square tubes, which results in a very good heat transfer due to the relatively large circumference of the connecting lines in relation to the cross-sectional area.
  • inlet and outlet connections of the register are arranged on the same collector, one inlet connection and two outlet connections being provided, between which the collectors are arranged, which results in very favorable flow conditions.
  • a throttle valve controlling the flow e.g. a motor flap is arranged which is controlled as a function of a sensor which detects the temperature of the fluid.
  • a buffer store for the fluid and optionally a temperature sensor controlling the burner output are preferably provided.
  • the arrangement of a buffer memory reduces the time periods in which the burner is in operation.
  • An arrangement of a *. Temperature sensor controlling the burner output succeeds in making a corresponding adaptation of the burner output to the actual demand possible when a corresponding temperature of the fluid is reached, which also results in energy savings.
  • Particularly favorable operating conditions result when the sensor is connected to a controller that controls the position of the throttle valve.
  • the flow through the boiler can thereby be regulated in accordance with the respective temperature of the fluid.
  • a simple two-point control can also be provided for the throttle valve and this can be provided with a correspondingly slow-running drive.
  • a thermostat is sufficient as a sensor that starts driving the throttle valve when a corresponding temperature is reached, so that it moves in the direction of its maximum throttled position runs and thereby slowly reduces the flow. If the temperature of the fluid drops, for example due to a sudden increase in heat demand, the thermostat reverses the drive of the throttle valve and this begins to run slowly from the throttled position to the fully open position.
  • Figure 1 schematically shows a device according to the invention and Figure 2 schematically shows a register.
  • the boiler 1 has a combustion chamber door 2, in the opening of which a burner (not shown) can be used.
  • the combustion chamber 3 of the boiler is delimited by a double jacket 4, which is connected via an inlet and an outlet nozzle 5, 6 to a water circuit 7, e.g. for heating, can be connected.
  • the outlet nozzle 6 protrudes through the actual double jacket 4 into an additional container 8 which communicates with the latter and is penetrated by smoke guide tubes 9.
  • These smoke guide pipes 9 guide the exhaust gases from the combustion chamber 3 into a smoke collection space 10, from which they flow into a fume cupboard, not shown.
  • a register 11 is also arranged in the combustion chamber and is directly exposed to the action of the flame of the burner. This register is connected upstream of the double jacket 4, so that the return of the water circuit is connected to the inlet 12 of the register 11.
  • the outlet connection 13 of the register 11 is connected to a buffer store 14, the outlet of which is connected to the inlet connection 5 of the double jacket 4.
  • a temperature sensor 19 is installed in the line 18 from the outlet connection 13 of the register 11 to the buffer store 14. This is connected to a control system, not shown, which in turn is connected to the throttle valve 15 or its motor.
  • the control of the throttle valve 15 can either be designed as a two-point control, the temperature sensor emitting a signal when a certain temperature is reached, which leads to the throttle valve running towards its maximum open position. A corresponding slow movement of the valve body is provided. If the temperature of the water falls below a certain level, the temperature sensor 19 emits a signal which causes the throttle valve 15 to return to its maximum closed position.
  • a PI controller can also be provided for more precise control, although the sensor 19 must emit a corresponding analog signal.
  • the flow through the boiler or the register 11 and the double jacket is regulated depending on the current temperature of the water.
  • thermostat 20 is also installed in line 18, which switches the burner from full load to part load when a certain temperature is reached.
  • a safety thermostat 21 is installed in line 18, which shuts off the burner when a dangerously high temperature is reached.
  • the register 11 has a front and a rear header 14, 15, which are connected via lines 16 made of square tubes.
  • the rear header 15 has an inlet 12 and two outlet ports 13 and is divided by two partition walls 17 which are arranged on both sides of the inlet.
  • the inflowing water flows from the rear header 15 via part of the lines 16 to the front header, where it rises and flows back into the rear header 15 via another part of the lines and then via the two outlet ports 13 to the inlet port of the double jacket 4 flows.
  • the register 11 Since the register 11 'is set aus ⁇ the action of the flame of the burner, the gas flowing through the register 11 er ⁇ water is heated before it flows into the double jacket.

Abstract

Dispositif pour une installation de chauffage avec une chambre de combustion (3) pour un brûleur, chambre de combustion (3) qui est entourée d'une enveloppe double traversée par le fluide à chauffer. Pour améliorer son efficacité, on prévoit avant l'enveloppe double un registre (11) disposé dans la chambre de combustion et exposé à la flamme. Pour améliorer encore plus son efficacité, on a prévu à l'entrée du registre (11) une soupape d'étranglement actionnée en fonction de la température du fluide, ce qui permet, grâce à l'étranglement de l'écoulement, de maintenir la différence de température entre l'entrée et la sortie du fluide à une valeur relativement élevée, même lorsque la température du fluide augmente.
