Definitions

  • the invention relates to an infrared heating system, comprising at least one heating pipe and a number of burner units distributed over the length of said pipe for heating the pipe in such a way that it emits infrared radiation from its surface, said heating pipe at one end being provided with one or more air supply apertures, and at the other end being connected to a suction pump, while control means are present for setting the heat capacity of the system, said control means having a throttle valve.
  • Such a system is known from EP-A-0070360 and is used for heating, inter alia, shops, offices, warehouses and factories.
  • control means make it possible not only to adjust the heat capacity of the system, but also to maintain the desired heat capacity by means of a simple setting if gaseous fuel with a different Wobbe index is used.
  • the object of the invention is to avoid this disadvantage, in other words, to place the control means outside the influence of the hot gases, while a good regulation of the heat capacity can still be achieved by means of the throttle valve.
  • the above-mentioned throttle valve is to this end fitted in a branch of the heating pipe or connecting pipe to the suction pump which (branch) is placed downstream of the burners and is in communication with the environment.
  • the throttle valve placed in the branch regulates the quantity of entrained air which may enter the heating system and, at a particular suction capacity of the suction pump, consequently the value of the partial vacuum in the system. This partial vacuum determines the heat capacity.
  • the infrared heating system shown comprises two heating pipes 1, 2 which are connected to a common connecting pipe 3.
  • a suction pump 4 is connected at the free end of the connecting pipe 3.
  • Each of the heating pipes 1, 2 is provided with a number of burner units 5 placed in series and having a control box 6 for regulating the amount of combustible gas and combustion air to the burner 7.
  • burner units 5 are described in the above-mentioned EP-A-0070360 and in EP-A-0034264. These units consequently require no further explanation.
  • a plate 10 with at least one air supply aperture is fitted at the free end of each heating pipe 1, 2.
  • a partial vacuum is created in the heating system by means of the suction pump 4, in which case additional air is sucked into the system through the aperture in the plates 10 and the mixture of combustion gases is discharged by means of the suction pump 4.
  • the aperture in the plates 10 has a fixed cross-section.
  • the partial vacuum in the system determines the heat capacity.
  • the connecting pipe 3 is provided with a branch 8 which is in communication with the environment, and in which a throttle valve 9 is placed.
  • the quantity of entrained air which can flow into the system through the branch 8 is regulated by the setting of the throttle valve 9. This setting can be altered by means of a motor 9 (or other setting device).
  • the quantity of entrained air drawn in through the branch at a certain suction capacity of the pump 4 determines the level of the partial vacuum in the pipes 1, 2 and 3, and thus the heat capacity of the system.
  • throttle valve 9 is not exposed to the corrosive action of the hot combustion gases during operation, but is situated in the cool air flowing in through the branch 8. No throttle valves are placed in the pipes 1, 2 and 3.
