Definitions

  • the invention relates to a device for generating heat from at least one energy carrier medium with the addition of air, with at least one fan for introducing an energy carrier-air mixture into a burner.
  • Devices of the aforementioned type are used as so-called heaters application for heating rooms in private homes as well as in commercial units.
  • An energy carrier medium for example natural gas
  • a heat transfer medium for example water
  • the burning of the energy carrier medium takes place with the addition of air.
  • the presence of air is required to form a flame with the highest possible efficiency.
  • an ionization signal is often obtained in the flame itself, on the basis of which the amount of fuel is adjusted.
  • the problem is that generic devices are also used from one and the same series of manufacturers at different locations.
  • the locations may differ in terms of their altitude as well as in terms of their respective available energy carrier media and / or climatic conditions. Also problematic may be different exhaust systems (eg lengths).
  • a generic device should run stable, for example, with a power less than 2 kW.
  • the invention has for its object, a device for generating heat mentioned above better and more accurate than previously known in the art, so that it can be used for services in the range of less than 2 kW.
  • This object is inventively achieved in that in a guide for the air to be added or for an energy carrier-air mixture at least one mass flow sensor for the air or for the energy carrier air mixture is arranged, which is connected to a fan acting on the control.
  • a mass flow sensor is arranged in the guide path for the air to be supplied or for an energy carrier-air mixture. With this mass flow sensor, the mass flow of tasumblelichen supplied air is also detected in a mixture. By this immediate determination air pressure differences due to different altitude levels and thus due to different air pressures can be compensated. The presence of different temperatures supplied air and different exhaust systems can be considered. These also affect the air mass flow.
  • the mass flow sensor is linked to a control for the blower, so that its determined data flow into the control of the blower. According to a development of the invention, it is provided that the mass flow sensor is connected directly to the blower. The mass flow sensor can thus be used to control the fan. It is no longer specified only the speed of the fan, but actually supplied by the fan z.
  • Air quantity is detected and assumed as a value for the speed. The knowledge of the amount of air supplied then also allows a targeted supply of energy carrier medium. There can also be differences in the energy carrier medium, with all types of gas (eg the II and III gas families) differing from each other.
  • the mass flow sensor is connected to the control for the fan via a converter to speed.
  • a speed can be read directly from the measured mass flow signal, which is fed to the control for the blower.
  • the mass flow sensor suggests characteristics of the fan, this can be controlled very accurately.
  • the guide path is formed by at least one connection.
  • the connection forms a receiving area for the mass flow sensor.
  • a second signal on the quality of the flame in the burner is measured.
  • This second signal can be fed to a control for the combustion.
  • the signal helps detect torch characteristics to enable stable operation even at low power.
  • This second signal may be, for example, an ionization current value.
  • the device according to the invention has a combustion chamber 1.
  • a burner 2 is arranged, a flame formed by the burner 2 is checked by a Ionisationsflammencer 3.
  • the ionization flame sensor 3 is connected via a line 5 with a combustion control / regulation 15.
  • the gas supply via a gas valve 10, which is linked via a connection 11 with the combustion control / regulation 15.
  • the mixture of added gas and added air is accelerated by a fan 12, this fan 12 is acted upon by a connection 11 of a control / regulation.
  • the control is a mass flow control 18, since this mass flow control 18 is via a Connection 11 is directly linked to a mass flow sensor 14.
  • the mass flow sensor 14 is disposed in a connection 13 for the air.
  • Fig. 1 there is a control / regulation of the blower 12 based on the measured mass flow sensor 14th
  • the mass flow sensor 14 forms a speed signal, which is input via the connection 11 into the control, which here is a speed control 17.
