Description

"Heating burner"

description

The present invention relates to a heating burner for a heating system.

Heating burners are used for a variety of applications. They are used for heating buildings, surfaces and liquids, whether for everyday use or for example for a swimming pool. Even if the requirements that arise in the various fields of application, differ partly strong, a request to the burner all application scenarios have in common. It is, at any point in the system to be heated entering an certain required temperature len, the temperature can vary greatly over time, the response time of

Heating burner should be short, however. To make matters worse, the system often reacts slowly to the heating of the burner.

To meet this requirement, most heating burners are equipped with an input that specifies the desired set temperature, as well as at least one sensor, the current temperature in the system is determined. Internal control methods attempt to heating burner or its combustion flame to control so that the actual temperature closely matches the desired temperature. This scheme applies to, as I said, be aware that the reaction time of the entire heating system is relatively sluggish, the setpoint requirements vary constantly and an efficient and maintenance-free heating is required. A high efficiency of the heating burner and an exhaust gas low and soot-free burning of the fuel used in each case is provided for the commercial heating burners.

Essentially, there are in the regulation of the heating burner between two methods, either singly or used in combination:

- the method intermetierende

- the modulating method In the intermetierenden control is an area around the desired set point temperature determined. During the combustion of heating burners knows only two jam. In a burning status is unregulated burned fuel and produces heat energy. In a detached status no fuel is burned, additional heat energy is not passed on to the heating system. Falls below the actual value of the lower interval limit of the desired value, the heating burner is ignited and burns until the actual value exceeds the upper limit of the interval. Thereafter, the burner is switched off and remains in this state until the actual value determines that a re-ignition is required. An actual temperature curve as typically existeth at a heating burner with a intermetierenden process can be seen from the figure 4a. The intermetierende method has the advantage that a low-emission and the calorific value of the fuel optimally exploitative to ensure combustion, the interval length is selected to be relatively generous and also a hysteresis occurs due to the possibly long reaction time the disadvantage. Therefore, there is a strong positive and negative control, which affects the quality and efficiency of the system. First, the heat energy is rarely exactly delivered, which is really desired, on the other hand, the heat loss is increased by the strong overriding the actual power in the governing systems and leads to wear (eg calcification).

The modulating method controls the heat output in analogy to the actual value of the temperature in the system. For example, the fuel supply can be regulated within a control range. Since the control range is finite, must be changed in the process at a intermetierende above or below the control range. The mentioned in this method disadvantages are equally, if not more so, on.

it is also difficult in this method to control the controlled variables (for example, air supply and fuel supply) so that it comes over the entire control range to an efficient, low-emission combustion.

Starting from this prior art, it is an object of the present invention to provide a heating burner, which provides for efficient and clean manner, a desired focal power. The object is solves by a heating burner according to the features of claim 1.

According to the invention the object is achieved by a heating burner for a heating system with a control device, with at least one primary sensor for detecting a heating output of the heating burner and with actuators which an ignition device for igniting fuel, an air supply device for feeding combustion air and a fuel conveyor for feeding fuel comprise the ignition device, wherein the delivery rate of the fuel delivery device is substantially freely adjusted and the control device, the actuators set such that the fuel is ignited in periodically recurring ignition intervals and burns for an adjustable focal interval, the heating power by the control device over the length of the combustion interval in is controllable respective ignition interval.

The central idea of ​​the invention consists in the fact that the control means ignites the fuel at regular intervals and runs a combustion flame at predefined performance. The heat output, which produces the heating burner is so regulated only by the respective burn time the adjustable firing interval. In essence, the controller only needs three phases within a combustion interval differ, in which the focal power is down to a booted before defined value an initialization phase, a constant internal phase in which the focal power is maintained at a constant value, and a stop phase, in which the internal power is returned again to almost zero.

The control means may therefore be adapted to the three phases of these

Actuators optimally operates that an efficient combustion of the fuel is ensured. In the control device of the actuators particularly the regulation of the fuel-air ratio is decided, therefore, at least the delivery rate of the fuel delivery device according to the invention is freely adjustable. By accurately controlling the heat output leads to lower heat losses in the entire heating system, especially in the lines.

Preferably, the firing intervals are less than or equal to 60 seconds. A quick reaction of the heating burner is guaranteed so and the actual power of the heating burner adapts perfectly to the target power on. An overshoot and undershoot of the heating power can be avoided.

Preferably the fuel is a liquid fuel, in particular rapeseed oil or other natural oils.

It is advantageous if the actuators include a motor that enables a truncated cone in rotational movement about its longitudinal axis, that exits via an entry opening into the truncated cone is mounted fuel due to the centrifugal force at an outlet orifice and is atomized. The truncated cone is thus a cylindrically shaped tube through the opening at the inlet, where the tube has a smaller diameter, fuel is introduced which is driven due to the rotation in the direction of the outlet opening. If the truncated cone driven fast enough so the escaping at the outlet of fuel due to the acting centrifugal is fugalkräfte atomized. Long-chain liquid fuels there will be a cracking of the molecule chains.

Preferably, the ignition device includes a heat recovery which is made of wärmeleitfä- higem material and discharges occurring during a combustion of the fuel to heat inflowing fuel. The heat recovery may be, for example, a rod, a tube with an inner, a motorized impeller or other structure that is appropriate to dissipate some of the heat occurring during the combustion of the fuel. This derivation takes place in the direction of a fuel supply line. Thus, the inflowing fuel to be heated just below the ignition temperature without the provision of additional preheaters.

Alternatively, it is also possible to preheat the inflowing fuel to a temperature above the respective ignition temperature, so that it comes directly for igniting the fuel at the supply of air.

Preferably, these heat-recirculation is arranged at least in sections in the interior of the hollow cylinder above the outlet opening outstanding. Thus, the resulting at the outlet opening of the truncated cone heat is transported away in the direction of the inlet opening of the truncated cone. in the interior of the truncated cone since oxygen defect, the fuel can be preheated to temperatures above the ignition point. It was only on leaving the truncated cone through the outlet opening it comes to inflammation.

In particular, for igniting the fuel in the initialization interval or

Initialization phase, the igniter preferably comprises a preheater, which heats the fuel to ignition temperature. Because outside the combustion interval is not enough internal capacity exists to sufficiently preheat the inflowing fuel into the initialization interval, it is helpful to provide an external preheater. The preheating can be carried resistive or inductive. It is crucial that the preheating is controlled by the control device and is controlled according to the phases.

Preferably, the pre-heating comprises a heating coil which surrounds the truncated cone. Thus, the fuel is heated indirectly through the truncated cone.

Preferably, the control device is designed such that it controls the fuel delivery device and the air conveying means such that during the firing interval, preferably in an initialization interval or initialization phase and a stop interval or stop phase, a substantially constant air-fuel - is present ratio at the ignition device. The air-fuel ratio can be selected so that the most efficient possible in particular soot-free combustion of the fuel is ensured. Because this type of intelligent controller of the heating burner must be rarely maintained and guaranteed, despite the frequent Neuentzündens efficient use of the fuel.

It is advantageous if the heating burner having an air flow sensor for determining the flow rate of the air conveyor. The control device can thus control the time required for the ignition and burning of the fuel air not only for a default mode, but to regulate as required. Besides air flow sensors and various temperature sensors can be provided both for fuel and for air, and flow sensors for the delivery of the fuel.

Preferably, the control means controls the actuators, in particular the fuel pump or -fördereinrichtung and the air conveyor, such a that outside the combustion interval, a pilot flame is present. A Neuentzünden of the fuel is not necessary and a sufficiently powerful device therefore need not be provided. By holding a pilot flame may further an explosive ignition of the fuel can be avoided in the initialization phase. The pilot flame can also be used to provide heat for preheating of fuel and thus to ensure an efficient combustion of the fuel over the entire firing interval of time.

Preferably, the control device is designed such that the fuel pump outside the combustion interval controls to supply the pilot flame, that less than one percent, preferably less than one per thousand of the maximum flow-rate of the fuel pump is promoted.

In the following description, the same reference numerals are used for identical and identically acting parts.

A heating burner according to the invention may comprise the components shown in FIG Ia. A central unit of the Heizbtenners forms the control device 10. This is connected to a plurality of actuators, in the present example, an ignition device 50, a sprayer 70, an air conveyor 80, a fuel conveyor 20, a cracker device 30 and a preheating 40. The controller 10 of the heating burner regulates and controls the respective actuators such that an efficient combustion, ignition and down rules or deleting of the fuel is ensured. Efficient that the calorific value of the fuel is optimally utilized, while a low-emission and soot-free combustion is ensured, so that maintenance of the heating burner according to the invention is rarely necessary in this case means. For the control of the actuators, the control device 10 receives signals from a plurality of sensors 60. These sensors 60 include at least a primary sensor, by means of which the controller may determine an actual temperature of the heated system.

In the present heating burner of this primary sensor is a Heizwassertemperaturfühler 65 which determines the temperature of a heated by the heating burner heat cycle. The control device is designed such that it can determine a difference between the actual temperature and a target temperature and regulates the actuators such that this difference is as low as possible at all times. Since the erfϊndungsgemäße heating burner namely, has a very small number of states, the ignition of fuel, the burning of fuel, the deletion of the combustion flame or reducing the combustion flame as well as an idling without combustion flame or with reduced combustion flame, a pre-configuration of the control device 10 is also conceivable. This pre-configuration determines optimum parameters for controlling the actuators for each of these states. In the example shown in Figure Ia and Ib embodiment, the sensors 60 also include an air temperature sensor 61, an air flow sensor 62, a fuel temperature sensor 63 and a fuel flow sensor 64. The fuel flow sensor 64 and the air flow sensor 62 will deliver the Steuereinrich- tung 10 signals that allow this to draw conclusions about the performance of the fuel delivery device 20 and the air conveyor 80th The air temperature sensor 61 and the fuel temperature sensor 63 help of the control device 10, the pre-heater 40 to control so that there is an optimum combustion of the fuel.

A combustion chamber 1 of the invention comprises, as schematically shown in Figure 2 two leads. The a, a fuel line 21 to the combustor 1 to the fuel, the other an air line 81 provides the necessary oxygen required for the combustion or the oxidant. In the present embodiment, it is in the fuel to be burned to rapeseed oil. The fuel is stored in a fuel tank 24 and conveyed via the fuel line 21 by a fuel delivery device 20 to the combustion chamber. 1 Herein, the crude oil passing through a pre-heater 40, which heats the fuel to ignition lighter and a cracker 30, which prepares the fuel. A further functional unit, a sprayer 70 is provided directly to the combustion chamber 1 and the mixed

Fuel with the supplied via the air pipe 81 air. An igniter 50 provides ignition of the air fuel mixture in the combustion chamber. 1

It can be on a separate ignition device 50 inside the combustion chamber 1 dispensed with if the preheater 40 heats the fuel to a temperature above the specific ignition temperature. In a mixing of the fuel with the air, there is a spontaneous ignition. The preheater 40 therefore assumes the functionality of the igniter 50. Figure 3 shows the structure of the off schematically illustrated in Figure 2 guide shape of the heating burner according to the invention. The air line 81 is in the form of a generous tube. At one point of the air conduit 81, the fuel line 21 passes through the outer wall of the air pipe 81 and extends further in the interior of the same. The fuel line 21 and air line 81 are still separated from each other.

A first opening of the fuel conduit 21 opens into the fuel tank 24 from which the fuel to a second opening of the fuel line is supported 21st This second opening includes in the interior of the air pipe 81 airtight with a Eintrittsöff- voltage 35 of a truncated cone 32nd The truncated cone is driven by a not shown motor 37 such that the fuel entering via the inlet opening 35 in the interior of the hollow truncated cone is promoted 32 due to the centrifugal force to an outlet opening 36 which faces the inlet opening 35 towards, but on the basis of the shape of having a truncated cone 32 has a larger diameter. Due to the force applied by the motor 37 centrifugal force the material introduced into the truncated cone 32 crude oil is cracked at a separation edge along the outlet opening 36, both mechanically as well as with the zoom brought via air line 81, the truncated cone 42 surrounding air is mixed. The motor 37 and the truncated cone 32 thus form the tonal radio units of the atomizer 70 and the cracking device 30 of FIG Ia. The truncated cone 32 is loosely surrounded by a heating coil 44th This not only heats the air surrounding the truncated cone but also the truncated cone 32 itself. Since the truncated cone 32 is made of thermally conductive material, the thermal energy of the heating coil is transferred to the fuel in the interior of the truncated cone 32 44. The heating coil 44 thus has a dual functionality and preheats both air as well as fuel.

The preheated fuel ignites once it is mixed with the air. The resulting heat power is output not only as a heating power of the heating burner but leave a small portion of a heat recovery 42, which extends in the form of a metal rod in the interior of the truncated cone to the inflowing fuel in the truncated cone 32nd A fuel delivery device 20 and an air conveying means 80 (see figure Ia) are not shown in the figure 3, but can be provided easily to 81 or in the fuel line 21 or the air line.

The actuators are, as shown in Figure Ia, connected to the control device 10 and control the present invention the heating burner that this t z the combustion flame at a preset focal power L regulates high at constant preset ignition intervals, and this for the duration of the firing interval t B maintains ( see FIG 5a). The duration of the firing interval t B is determined by the control means 10 in dependence of the contributions to be paid by the heating burner heating power. 5a shows a time

Burning power graph. Here are shown for three ignition intervals t. An ignition interval is in the selected embodiment, the length of 100 sec. Thus, the controller regulates every 100 seconds the combustion output L up to a preset level. And retains this higher firing power at L during the adjustable focal interval t B. The controller 10 (see Figure Ia) is designed such that it determines for the respective time required optimum heating power, the length of the fuel interval t B. In the diagram of Figure 5a the control device 10 determines that approximately 20% of the maximum heating power in a first ignition interval t z is needed. Accordingly, it regulates at time t = 0 the combustion output L to the preset level and maintains this level for about 20 seconds. The remaining 80 seconds of the first firing interval t z the actuators are controlled by the control device 10 so that the internal power L is practically zero. At time t = 100 determines the control means 10, the t z 60% of the maximum power is required for optimum heating in a second ignition interval. Accordingly, the combustion interval t B in this second ignition interval t z for about 60 seconds. The same applies to a third ignition interval t z beginning at time t = 200th

Figure 5b shows a time-burning power graph of the first firing interval t z in Figure 5a, the focal length of the interval t B is as mentioned 20 seconds. The start or stop phase, ie the period in which the control unit 10, the internal power L highly regulated to the preset high level or down regulates this as the initialization interval t, and stop interval t s, respectively. For efficient and clean combustion of the heating burner according to the invention, a constant burning material-oxygen ratio in these phases is particularly crucial. The control device 10 controls the actuators accordingly.

A detailed view of the second firing interval t z 5a figure can the time-burning power graph of Figure 5c are removed. By this accurate control of the heating capacity can be improved Istwerteinstellung, as shown in Figure 4b, achieve. Here, the abscissa is time and the ordinate indicates the actual temperature.
