Definitions

  • the invention relates to a gas blower burner with modulable burner power for a gas heater according to the preamble of claim 1, a method of operating a gas blower burner according to the preambles of claim 8 and a gas heater according to claim 11.
  • Gas fan burners with modulable burner performance are well known. They are usually used to heat a heating fluid such as heating water or drinking water in a gas heater. In this case, combustion air is supplied to the burner via an air path and fuel gas via a gas path. The amount of air required for heating a Schufluidstroms is conveyed in accordance with the predetermined burner capacity or the predetermined Schufluidtemperatur means of a variable speed air blower in the air. The amount of gas corresponding to this amount of air is metered in the gas path with the aid of a gas valve. Air and fuel gas mix to a fuel gas-air mixture. For complete and low-emission combustion of the fuel gas, among other factors, a specific target composition of the fuel gas-air mixture is necessary.
  • the aim is an excess of air (air ratio) ⁇ SOLL ⁇ 1.3 compared to the stoichiometric minimum air requirement required for complete oxidation of the fuel.
  • a so-called pneumatic gas air composite causes this mixture composition.
  • An air flow meter arranged in the air measures the amount of the delivered amount of combustion air and gives an actuating signal to the gas valve, which releases a fuel gas amount corresponding to the desired composition of the fuel gas-air mixture.
  • the fuel gas-air mixture passes through a burner surface, which has the function of a flame holder in a combustion chamber, is ignited here by means of an igniter and burns with the release of heat. The heat of combustion is transferred in a heat exchanger to the heating fluid and this supplied to the use.
  • a Venturi nozzle For the air flow measurement in the pneumatic gas air network, a Venturi nozzle is usually used because of the low pressure loss.
  • the pressure difference between the inlet cross-section and the narrowest nozzle cross-section of the Venturi nozzle, which is proportional to the air volume flow, is measured, which acts as a control signal on a pneumatic gas control valve.
  • Known devices for mixing fuel gas and air of the aforementioned type are capable of realizing throughput variations in a range of about 1: 5 (corresponding to a pressure variation of about 1:25), since the available pressure range on the one hand by the blower and on the other hand is limited by the required minimum response pressure of the pneumatic control valve.
  • the limitation of the range variation range is accompanied by a similar limitation of the burner power range of a burner and the Schutsch.modulations Kunststoffs a gas heater.
  • Modern gas heaters with correspondingly modern gas jet burners have a comparatively low air ratio of ⁇ ⁇ 1.3 compared to previously customary burners.
  • the Wasserdampftauddlingtemperatur an exhaust gas depends on the air ratio of the combustion: With decreasing air ratio increases the dew point temperature. This results in a potential problem in the operation of modern gas heaters, namely the condensation of moisture contained in the exhaust gas to the cool combustion chamber walls and the cool surfaces of heat exchanger and exhaust pipe. This condensation is only allowed (and desirable) on condensing boilers since the components are designed accordingly. For conventional calorifiers, condensation must be avoided, otherwise moisture affected components could corrode and fail.
  • a tendency to condensation is also favored by the device heating power or temperature. On surfaces of high temperature (high heat output) either no moisture precipitates or it can dry quickly. At low surface temperatures (low heat output), the dew point temperature tends to fall below and there is precipitation of moisture.
  • thermoacoustic resonances Another potential problem in heater operation are so-called thermoacoustic resonances, which can lead to excessive noise pollution and, due to the accompanying mechanical vibrations, also to component failure. Often, the resonance phenomena occur especially at low relative burner powers and low combustion chamber pressures.
  • an increase in the heating power range of a gas heater or an increase in the burner output range of a burner is desirable in order to be able to serve very different heating requirements, such as, for example, a domestic hot water tap for washing hands, a tapping process for inserting a bath or caused by heating an apartment.
  • very different heating requirements such as, for example, a domestic hot water tap for washing hands, a tapping process for inserting a bath or caused by heating an apartment.
  • the invention is therefore based on the object to provide a gas blower burner with an extended burner power range as well as a method for its operation, which help avoid the water vapor condensation on Abgasbehot components and thermoacoustic resonance phenomena.
  • the burner should have a simple and compact design.
  • the gas blower burner according to the invention with modulable burner power for a gas heater with at least one air path for fan-assisted supply of combustion air, at least one gas path for supplying a fuel gas, a gas valve for quantity control of the fuel gas, at least one burner surface as a flame holder and at least one upstream of the burner surface arranged distribution space in the the combustion air and the fuel gas or a fuel gas-air mixture open, wherein the burner surface and the distribution chamber are divided into at least two areas, wherein a first burner surface area is associated with a first distribution space and a second burner surface area is associated with a second distribution space area, and wherein the gas path at a branch downstream of the gas valve and upstream of the distribution space is divided into at least two partial gas paths, each with an associated region of the distribution space in Verbin standing.

This can be e.g. reach through different path lengths, line diameter and fixed or adjustable throttle cross-sections. This ensures that with the help of a single gas control valve and despite the same control signal ranges from the air flow meter on the different partial gas paths different sized amounts of fuel gas can be metered.
  • An embodiment is characterized in that a fan is arranged in the air path, wherein the air path opens downstream into at least one region of the distribution space.
