Definitions

  • the invention relates to a control or regulating device for automatic gas firing systems of heating systems of the type mentioned in the preamble of claim 1.
  • the heating power depends on the amount of combustible fluid supplied to the burner and the ratio of this amount to the combustion air supplied to the burner. It is advisable to set a ratio between fluid and air that is determined for optimum efficiency.
  • the air is driven by a fan at a constant speed in a connecting line to the burner, while a throttle valve in the connecting line which can be controlled by the controller serves to control the air pressure in the connecting line.
  • the setting element for the pressure of the combustible fluid supplied to the burner is then controlled as a function of this air pressure.
  • the invention has for its object to simplify such a control or regulating device above all constructively.
  • the saving in energy is desirable and the burner should enable high efficiency and low-pollutant operation even in burners of relatively low output up to around 30 kW even in partial load ranges.
  • the use of a throttle valve for controlling the air pressure can be dispensed with. Instead, the air pressure is varied by controlling the speed of the fan. This not only avoids the effort of an additional throttle valve with the corresponding mechanically moving parts and their susceptibility to malfunction, but can also save drive energy since the blower is in contrast to the prior art, in which it is always at maximum speed regardless of the size of the required air pressure must run in the connecting line, the required air pressure can be adjusted accordingly in the speed.
  • a DC motor is used to drive the continuously modulating blower, which can be controlled by, in particular, pulse-width-modulated, that is to say digital, control signals from a control unit which is acted upon by the controller.
  • While the dependency of the fluid pressure on the air pressure can be established in accordance with known control devices in that the fluid pressure is regulated as a function of the air pressure or is tracked in order to supply the desired fluid / air ratio to the burner, the air pressure is controlled as a function of the heat requirement or parameters decisive for the heating via the speed control of the DC motor and therefore of the fan.
  • control and regulating devices can be used for example for small gas heaters (wall or floor models) with gas fan burners, with which both the heating water of a heating system and the process water of single-family houses or apartments can be regulated, in particular in the power range up to 30 kW.
  • the control device can also be used for fan burners in intermittent operation with devices for complete premixing of the fluid / air mixture and with closed combustion chambers.
  • the air pressure as a reference variable for the gas pressure regulator of the compact gas control system.
  • a modulation range of at least about 1: 3, for example 10-30 kW, but preferably over 1: 5, enables optimum efficiency and low-pollution operation even in the low-load range.
  • a control valve is used as an adjusting element for the fluid.
  • the motor that drives the blower is, in particular, a DC motor with a supply voltage of about 35-40 V. It takes up little space and also causes relatively low costs.
  • the air pressure in the connecting line between the fan and burner can also be used for other control tasks.
  • a switch-off can be carried out if the air pressure falls below a limit. While the actual speed values of the blower or its DC motor sensed via the Hall sensors also represent a measure of the air pressure in the connecting line, a slipping of the fan from the blower shaft or the adjustment of fan blades could lead to a reduction in air pressure even if the blower speed remains the same. However, if the air pressure in the connecting line is sensed and it is found that it has fallen below a limit value, this is an indication of a malfunction.
  • an ignition signal can also be generated for the ignition unit in order to start the burner operation by means of an automatic burner control.
  • the control device then acts simultaneously as part of an automatic burner control.
  • control can be done so that a timer for a predetermined pre-purge time for a high fan speed and a high air pressure, i.e. a large air flow through the burner and boiler room, but at the same time prevents the supply of flammable fluid to the burner
  • a signal can also be generated when the supply of combustible fluid is shut off, as a result of which the control unit continues to apply a control signal to the blower's direct current motor for a certain time, while the fuel supply is shut off in order to flush the burner and boiler room and the chimney with air and combustion gases to free.
  • the fan can be set to an adjustable value, e.g. between 50 and 70% of its maximum speed, i.e. its full load, can be reduced in order to achieve optimal ignition when used as an automatic burner control.
  • an adjustable value e.g. between 50 and 70% of its maximum speed, i.e. its full load
  • gas flows as a combustible fluid F via a feed line ZL to the burner B of a heating boiler HK.
  • the gas pressure P F of the fluid F is regulated by a pneumatic constant or ratio pressure regulator valve V as a function of the air pressure P A , which is led from the outlet of the blower G to the control valve V.
  • the temperature controller R adjusts the speed n IST of the motor M G and thereby also the air pressure P A in the connecting line VL.
  • the constant pressure control valve V adjusts the gas pressure P F in accordance with the actual value of the air pressure P A , so that the optimum amount of gas is always adjusted to the current amount of air.
  • the DC motor M G can be set at speeds between approximately 200 and 6000 rpm with a power of up to 22 VA.
  • the air A is conducted to the burner B via the connecting line VL.
  • the air pressure P A in the connecting line VL is determined by the air pressure sensor F A according to a special embodiment of the invention.
  • the fan G is driven by a 39 V DC motor M, the speed of which can be sensed as the actual speed value n ACT using a speed sensor F n , in particular a Hall sensor.
  • the temperature is regulated via the controller R as a function of actual temperature values, for example the room temperature T R , the boiler temperature T K , the outside temperature T A and / or the flow temperature T V , which is sent to the controller via an analog / digital converter A / D R supplied and there with setpoint values, eg or be put in relation.
  • the controller R generates an output signal that corresponds to the speed setpoint n and is compared in the comparator with the speed actual value n ACTUAL .
  • the control unit St G can be influenced, which in turn could generate corresponding control signals S ST for controlling or regulating the speed of the DC motor M.
  • the controller gives the control device a start command to the automatic firing device, which happens, for example, when the temperature T in the process water circuit or in the heating circuit has dropped below a minimum value.
  • the DC motor M G of the blower G is subjected to control signals S ST , in particular pulse-width-modulated, so that its speed n ACT increases to a maximum value as soon as an (adjustable) setpoint (speed setpoint n SET ) is reached and the external one Air pressure detector LP closes its contact.
  • the pre-rinse time tv begins. At this time, a certain air pressure P A is reached in the connecting line VL.
  • the burner control can continue its function program when the required minimum values are reached. If the speed and / or the air pressure have not reached the predetermined limit value before the start of the pre-purge time tv, a lockout occurs.
  • the speed must IS n G of the fan during the pre-purge time tv a minimum value of, for example, 2400 rev / min exceed.
  • An ignition signal Z is then applied to an ignition unit of the burner B during the ignition time tz, for example to ignition electrodes thereof, while the fan G continues to run at the same speed, for example 40% of the maximum speed, but the maximum value of 2900 rpm in this example according to FIG 3 may not exceed.
  • the valve in the supply line ZL opens, i.e. the pneumatic pressure regulator V for the combustible fluid F, which serves as an adjusting unit, whereby the safety time ts begins, within which a flame signal must be detected by a flame sensor, otherwise the lockout occurs.
  • This safety time ts is, for example, up to 10 s
  • the pre-rinsing time tv can be, for example, up to 50 s and the maximum braking time tbre is also of this order of magnitude.
  • the transition to the operating position takes place and the burner operating time tb begins, during which the fan speed n ACT is dependent on the pulse-width-modulated control signals S ST and this in turn is dependent on the output signals specified by controller R in a speed range (adjustable), which, according to FIG. 3, moves between approximately 600 and 6000 rpm, as the maximum value specification and plausibility limit, while the highest speed is typically 4000 rpm. It is not necessary to monitor the air pressure during the burner operating time tb, since the speed sensor Fn with its output signals offers sufficient security.
  • the burner operation is set by the controller R at time C by stopping the supply of combustible fluid F to the burner B by the adjusting member V.
  • the fan G can remain in operation in order to blow off combustion residues.
  • this blocking time is tsp the fan speed N is ramped up (programmed) to full load, then the home run whereupon as a regular transition in the standby phase followed.
  • the device is equipped with a microcomputer MC; it takes on both the tasks of the temperature controller and the tasks of the burner control.
  • a further microcomputer MC 1 can be in data exchange relationship with the microcomputer MC, which takes over a monitoring function in order to ensure the safety of the burner control.
  • the flame sensor F F emits output signals both to the microcomputer MC and to the other microcomputers MC 1 serving for monitoring purposes.
  • Both microcomputers MC, MC1 can independently close or open two switching elements for the control terminals of the gas valve. The two computers also monitor each other for correct functioning.
  • a setting device allows the programming of the microcomputer MC by entering data into the memory SP.
  • the microcomputer MC initiates the initiation of control signals S ST in the signal generator SG.
  • the comparator Ve compares the actual speed value n ACTUAL with the programmed speed setpoint values n TARGET , in order to initiate corresponding functions in the event of deviations or exceeding or falling short of the speeds shown in FIG.
  • the two microcomputers MC, MC1 act on two switches S1, S2 connected in series in the 24 V AC voltage line WL; the line WL supplies the drive unit AA for the fuel gas valve V with electrical alternating current.
  • An advantage of this integration of the electronic control device is that it is unnecessary to use a separate control device with the associated components on the one hand for the burner control and on the other hand for the temperature controller.
  • a single signal generator SG is sufficient to generate and deliver the pulse-width-modulated control signals S ST , which perform their task both for controlling the start-up program (in the function as an automatic burner control unit) and for regulating the temperature during burner operation (in the function as a controller).
  • the Hall speed sensor F n sensed actual rpm values n IS not only during the start-up program (function as automatic firing), but also during the regular burner operation to control and regulate evaluated.
  • the air pressure switch or sensor F A ensures that when the burner controls are operated, ie in the "start-up phase", sufficient air pressure is always built up for purging the burner chamber and fireplace.
  • the speed n of the fan G can drop so low that the air pressure sensor F A no longer responds if the heat demand WA is low.
  • the use of an additional air pressure sensor is recommended, which responds to lower air pressure corresponding to a lower fan speed.
  • one or the other air pressure sensor can then be used.
  • the air pressure sensor F A also responds to the safety test, according to which there is a brief switch-off and restart at least once every 24 hours using the automatic burner control.
