Definitions
- the invention relates to a control device for a gas burner according to the preamble of claim 1.
- Such control devices are used, for example, for commissioning and for controlling the Normal operation of gas-fired heating devices used.
- heating devices are known in various designs such as boilers and wall heaters. With boilers exist those with fixed power, which are operated in the ON-OFF mode, but also those with variable Power at which the amount of gas to be burned is varied. Thereby exist Fan burners, to which the air required for combustion is supplied by means of a fan, and atmospheric burners without such a fan.
- JP-A-06 050533 from Patent Abstracts of Japan, Volume 018, No. 283 (M-1613) describes one Combustion control device in which the amount of gas is gradually adjusted to one corresponding amount of hot water is generated. The number of revolutions of the fan becomes corresponding the amount of gas set. The amount of gas flowing through the gas valve is controlled by a Gas pressure sensor measured. The amount of air conveyed by the blower is therefore always that of the Gas valve flowing gas quantity adjusted to prevent abnormal combustion.
- a control and regulating device is known from European patent application EP 614 046 known for the operation of a gas fan burner, in which the speed of a fan for the Air supply is infinitely variable.
- EP 614 046 known for the operation of a gas fan burner, in which the speed of a fan for the Air supply is infinitely variable.
- an additional pressure regulator By means of an additional pressure regulator, one of the Actual air supply adjusted combustion gas supply reached. This is intended for an optimal gas-air ratio can be achieved throughout the entire operating range.
- the invention has for its object to provide a control device for a gas burner, in which a control of the gas-air ratio is possible without expensive sensors.
- FIG. 1 shows a control and regulating device 1 for a gas burner 2, which has a fuel valve 3 and a Air blowers 4 are assigned.
- An external one acts on an input of the control and regulating device 1 Heating circuit controller 5 in such a way that the heating circuit controller 5 to the control and regulating device 1 to cover communicates the burner output required for the heat requirement.
- this heat demand signal controls the control and regulating device 1, the continuously adjustable fuel valve 3, with which the a fuel line 6 delivered gas is supplied to the combustion chamber.
- the size of the Heat demand signal thus determines the degree of opening of the fuel valve 3.
- a gas pressure switch 7 is arranged downstream of the fuel valve 3.
- the gas pressure switch 7 is designed as a switch which switches from an OFF position to the ON position as soon as the gas volume flow V G being conveyed and thus also the pressure p G in the fuel line 6 exceed a predetermined value V G1 or p G1 .
- the signal from the gas pressure switch 7 is transmitted to the control and regulating device 1 via a line 8.
- the control and regulating device 1 now controls the air blower 4 so that it rotates at a first speed D 1 when the gas pressure switch 7 is in the OFF position and that it rotates at a second higher speed D 2 when it rotates the gas pressure switch 7 is in the ON position.
- Heating devices are only operated in exceptional cases, for example during heating phases at the start of heating, at nominal load. Most of the time they run under reduced load in the so-called partial load range.
- the gas pressure switch 7 can now advantageously be set such that the value V G1 is somewhat greater than the gas volume flow V G required during the greater part of the operating time. The excess air is then optimal both in part-load operation and at nominal load. Since an amount of air corresponding to the maximum output no longer has to be heated in the partial load range, there is a significant improvement in efficiency.
- the maximum or maximum gas volume flow required in the partial load range from plant to plant can be different and since the air volume flow is not only dependent on the speed of the air blower 4, but also depends on the air resistance significantly influenced by the exhaust gas chimney, is advantageously the switching point of the gas pressure switch when starting the gas burner 2 7 corresponding to the maximum required in part-load operation or the maximum in part-load operation Gas volume flow set.
- gas pressure monitors can also be used 7 find application, each different according to a different gas pressure Gas volume flows is set. The speed of the air blower 4 can thus be adjusted in several stages change.
- a gas pressure switch 7 with several switching points can also be used for this purpose Find application.
- the functionality of the external heating circuit controller 5 can also be integrated in the control and regulating device 1 his.
