Definitions

  • the invention relates to a blower for combustion air in a wall / floor standing boiler.
  • blowers are used in household heating systems with fully mixed surface burners for heating either hot water or the heating water.
  • control and regulation takes place in the prior art generally via pneumatically controlled gas valves, which, however, due to their high tax performance lead to an increased volume flow of combustion air, as it is not required for the actual power generation is.
  • the invention is therefore based on the object of a blower to create an adequate output accordingly the desired performance requirement, i.e. temperature of the domestic water or heating.
  • the solution to this problem is a blower with a blower housing and a fan wheel for combustion air in one Wall / floor-standing boilers suggested one Air inlet (suction side) and an air outlet (pressure side) has and with a feed line for a preferably gaseous combustion medium is equipped, wherein at the air inlet a sensor device for determining the Air mass flow is arranged using an electronic Control unit is functionally linked and too of these signals for processing the combustion medium / combustion air ratio depending on the desired Heating power sends.
  • a device of this type is provided, a full-blown burner through the Recording the air and gas mass flow a homogeneous low-emission Provides combustion and guarantees it permanently.
  • the sensor device is an electronic air mass flow anemometer.
  • Anemometer has been used in a wide variety of measurement areas proven and provides sufficiently accurate signals for Determination of the mass flow of a gaseous medium.
  • a particularly advantageous embodiment consists of that an annular nozzle arrangement at the air inlet of the blower is formed on which the sensor device is arranged is.
  • the sensor device in a bypass is arranged in the gap of the ring nozzle arrangement opens. This ensures an optimal mass flow fed to the sensor device so that the corresponding measurement signals an error-free determination of the actual mass flow in the main flow.
  • the ring nozzle arrangement additionally assigns to the invention the nozzle gap for the air mass measurement another nozzle gap for the supply of the combustion medium.
  • the ring nozzle arrangement can be more integral Part of the housing wall at the air inlet of the fan is. It is advantageous that the ring nozzle arrangement surrounds the main stream of combustion air at the air inlet. This arrangement ensures a constant, homogeneous suction of the measuring air flow through the corresponding nozzle gap ensured.
  • an input channel is placed in front of the ring nozzle arrangement is.
  • the bypass can open into the input channel.
  • it can also bypass open into an annular gap in the interior of the entrance channel, so that according to the pressure distribution over the Cross-section an even suction of the measuring air flow is ensured.
  • the gas supply is controlled via a rotary valve / control valve which is an integral part of the blower housing is. It is advantageous if this rotary valve / control valve for the gas supply on the suction side of the blower is formed. This can make a rational Manufacturing can be achieved.
  • the training according to the invention advantageously allows that the electronic motor commutation is the mass flow evaluation takes over and depending on the result regulates the speed of the blower motor during the evaluation.
  • Fig. 1 shows a first embodiment of the invention Blower for combustion air, as in so-called wall / floor-standing boilers. It consists of a blower 1 with a fan housing 2 and a fan wheel 2 ', with an air inlet 3 and an air outlet 4. The air inlet is the suction side of the blower, whereas the air outlet designates the pressure side.
  • a feed line 5 for a preferably gaseous combustion medium educated.
  • a sensor device 6 arranged to determine the air mass flow serves.
  • the sensor device 6 indicates signals a control unit 7 which controls the combustion, e.g. the ratio of combustion medium / combustion air in Depends on the desired heating output.
  • the control device 6 consists of an electronic Air mass flow anemometer as it is commercially available is.
  • An annular nozzle arrangement 8 is arranged at the air inlet 3, the sensor device 6 on this ring nozzle arrangement 8 is attached.
  • the sensor device 6 is shown in FIG. 1 illustrated embodiment arranged in a bypass 9, which is in the gap 10 of the ring nozzle arrangement 8 opens.
  • the ring nozzle arrangement 8 has in the illustrated embodiment in addition to the nozzle gap 10 for the air mass measurement a further nozzle gap 11 (gas nozzle gap) for the supply of the combustion medium.
  • a further sensor device is in the gas nozzle gap 11 12 formed, the corresponding signals with respect to Mass flow of the combustion gas to the control controller unit 7 sends.
  • the control regulator unit calculates the corresponding gas mass flow Manipulated variables to the respective target values reach if they deviate from the actual values.
  • the ring nozzle arrangement is an integral part of the Housing wall 13 of the fan is formed.
  • the Housing wall part of the ring nozzle for the combustion gas form.
  • the ring nozzle arrangement 8 surrounds the main flow of the combustion air at the air inlet 3 ring-shaped. This will create a homogeneous mixing of the combustion gas with the main air flow achieved.
  • the sensors in separate components in the corresponding Lines or ring nozzle sections are accommodated, is the sensor arrangement according to the embodiment of FIG. 2 designed so that a common partition between the ring nozzle for the air mass measurement flow and the gas flow is formed by a measuring chip, so that a compact measuring unit is obtained.
  • Fig. 3 shows a next embodiment of an inventive Fan training, with an input channel 14 of the ring nozzle arrangement 8 is placed in front.
  • the embodiment is the sensor device 6 for the air mass flow arranged in a bypass line, which in the Input channel 14 opens.
  • Inside the input channel 14 is a covered ring channel 17 in front of an annular gap 15 formed into which the bypass 9 opens.
  • ring-shaped Suction becomes a homogeneous suction of the mass flow measurement volume achieved through the bypass 9.
  • a rotary slide valve / control valve 16 is shown applicable, that is controlled by the control unit 7 becomes.
  • the rotary slide valve / regulator valve is an integral part of the housing 2. In the illustrated embodiment is this rotary slide valve 16 for the Gas supply is formed on the suction side of the blower 2.
  • FIG. 4 shows the motor 18 of the blower 1, the Control unit 7 together with the electronic motor commutation the mass flow evaluation takes over and this regulates the speed of the blower motor can.
  • the control electronics are designed so that either the gas supply is regulated at a constant engine speed is or can be in a continuous target / actual comparison the desired power and the speed of the Motors and the gas supply adjusted accordingly become.
  • FIG. 5 shows an embodiment of the invention in side view, in which the gas supply 5 does not have a Ring nozzle at the air inlet, but near the pressure side takes place at the air outlet.
