Definitions
- the invention relates to a method and a device for regulating a Grate firing with movable grate, from the ashes over an end area of the Grate is removed or discharged, with the goods located on the grate
- the presence of embers, if necessary, in several places along the Gutweg is observed and depending on the observation, the air supply and / or the delivery speed of the fuel is regulated.
- the grate firing can be used to burn solid fuels such as Wood, bark, straw but also garbage.
- the grate can be an inclined (but also horizontal) stair grate, moving grate, moving grate or the like be.
- the solid fuel is added and then mechanically transported over this, the "primary air" from below the grate is fed.
- the ash is thrown away at the end of the grate.
- the burning zone is in the middle of the grate and so is the grate dimensioned that there is only more ash at the end of the grate, which then from Rust is thrown into a collection or conveyor.
- the method described in the patent specification DD 292068 (Steinmüller) automatically records evaluation criteria for the combustion progress and is supposed to Enable automation of control. This is used to record the radiation a burn on a grate which is essentially individual Combustion rust zones outgoing radiation detected and depending on the radiation controlled the control of the individual zones.
- a thermographic process makes it possible to measure the temperature of the grate the embers bed formed, i.e. a two-dimensional one To map the temperature profile in individual rust zones and thus each of the individual Targeting zones in order to optimize combustion in the zones and to minimize the formation of pollutants (dioxins, nitrogen oxides bib).
- the disadvantages mentioned can be avoided if the observation of the goods on the grate in the discharge or discharge area of the grate a viewing angle ( ⁇ ) of 10 ° to 30 °, preferably 16 ° to 20 °, on the occurrence of Light emission from the goods in the discharge or removal area is carried out and there the radiation in the wavelength range of the visible Light is detected integrally.

- the ember bed but only the rust discharge and not by illustration, but only by one integral detection of radiation in the wavelength range of visible light in the Field of view of the sensor (s) observed.
- the present invention would admit give little information to regulate the overall combustion on the grate, however, it helps to minimize the dropping of combustibles into the ashes and furthermore to make better use of the grate length, which also reduces pollutant formation.
- a device for controlling grate firing with movable grate, from which ash is discharged via an end region of the grate or is carried out, the goods on the grate for the presence of embers possibly observed at several points along the Gutweg and depending on it from the observation of the air supply and / or the conveying speed of the Fuel is regulated, it is provided that in the discharge or discharge area of the grate in a manner known per se at least one in the wavelength range of sensitive sensor element emitted by the embers is aligned, wherein the signals of the sensor element or elements, if necessary after passage through an amplifier, to the input of a control element for the grate feed and / or the fuel supply to the grate and / or the air supply to the grate can be laid and that the at least one sensor element is designed to receive light and a viewing angle of the sensor element of 10 ° to 30 °, preferably 16 ° up to 20 °, resulting shielding against radiation from other rust areas is available.
- a simple to implement embodiment provides that the shielding of the at least one sensor element against radiation from other rust areas of the wall of an opening in the combustion chamber wall in which the Sensor element, at least with its light receiver, is arranged, is formed.
- the at least one sensor element can also be shielded against Radiation from other areas of rust from one enclosing the light receiver Be formed sleeve.
- At least one can advantageously receive aligned by light from the discharge or discharge area of the grate Sensor element at least one more, in the wavelength range of the embers emitted light sensitive sensor element can be provided, which on the Receiving light that comes from an area that is adjacent to that of the at least one sensor element for observing the removal or Discharge area, adjoins the feed area and preferably approximately has the same width as the observed discharge or discharge area, and wherein shielding against radiation from other than that observed at the or discharge area adjoining areas is provided and the shield preferably of a sleeve enclosing the light receiver of the sensor element or is formed by the wall of an opening in the combustion chamber wall, in which the further sensor element at least with its light receiver, e.g.
- one Glass rod is arranged, and wherein the signals of the further sensor element if necessary after passing through an amplifier, to the input of a Control device for the grate feed and / or the fuel supply to the grate and / or the air supply to the grate, in particular for its removal or Discharge area, can be placed.
- a Control device for the grate feed and / or the fuel supply to the grate and / or the air supply to the grate, in particular for its removal or Discharge area can be placed.
- Glass rod the sensor elements directly or in itself known way over a fiber optic bundle with the electronic signal generator Be connected to the sensor element so that the signal transmitter is removed from Light receiver, protected against heat radiation, can be arranged.
- light beams transmitted by sensor elements to be led from the sensor elements to the signal generator via fiber optic bundles At this known training is a possibility of observing one Burner, the glass fiber bundles opening out in the center of the burner, so that can be observed directly there. In the present case, however, it is about the monitoring of an ember bed for visible embers nests, in which one appropriate shielding and also due to the high heat radiation of the Embers build up a removal of the auto switch is essential.

- surrounding sleeve on the outside with at least one, preferably with three Disks may be provided in the space between the sleeve and the sleeve surrounding wall are arranged.
- a cooling medium preferably air
- a Connection piece can be supplied, so that even in the case of higher temperatures in the Close to the grate a safe working method and a high durability of the device is achieved.
- the sloping feed grate according to FIG. 1 becomes firmer on the left side Fuel is given up and by the movement of the grate elements and the inclination of the grate conveyed to the right. In the zone labeled 1, the fuel first dried, gasification and combustion take place in zone 2 and in the Zone 3 still burns some fuel residues. For the most part, however, is zone 3 already covered with ashes. About the discharge 4, the ash 5 is finally from the Firing chamber discharged. Primary air 7 flows through the grate from below Rust is allocated according to the prevailing operating conditions.
- Ember bed height which can be e.g. is measured at position 80 but the presence of embers at the bottom of the grate.
- the invention is the burnout zone 3 of the grate by one or monitor multiple optical sensors. These optical sensors are on that Light embers sensitive and give a signal which is proportional to the received light intensity is.
- the sensors 8 are depending on the width of the bed one or more are placed side by side so that they just line the drop area watch the rust. These sensors should not give a light signal in normal operation receive.
- the sensors 8 are in principle for controlling the system with the Aim not to throw off burning fuel, sufficient and you could generally get by with the sensor (s) 8. However, it has proven to be proven to be advantageous - one sensor - or, in the case of very wide systems, several sensors 9 to attach, which are directed to that part of the fuel bed that is currently located above the viewing area of the sensors 8.
- This sensor (Sensors) 9 should very well receive a light signal during normal operation indicates that there is still embers and that the rust is full Length is covered with fuel.
- the sensor is also used in extreme part-load operation 9 can't see embers.
- the grate advance should be accelerated to the fullest possible to fill with fuel.
- the grate is for an even fuel allocation dimensioned and can only be used under this condition with a minimal Pollutant emissions are operated.
- a sensor 14 sensitive to light is an electronic component and may therefore not be exposed to a higher temperature. It also hangs The level of the signal depends on the operating temperature of the electronic sensor. It is So it is necessary to place the sensor in such a way that it does on the one hand light On the other hand, it can receive from the combustion chamber in one place located where it is not affected by the temperature of the firebox. Usually a temperature of 50 °, at most 70 °, may not exceeded - not even if there is a malfunction e.g. as a result of a power failure and possible cooling by air is no longer available Available. This problem is solved by using a glass rod 10 the radiation emitted by the embers is intercepted and be on by it end located outside the combustion chamber is guided, as in FIG.
- the glass rod 10 is in a detail shown in FIG. 3 Protective sleeve.
- the glass rod receives the Radiation from the embers, the viewing angle ⁇ of the glass rod favorably is restricted between 10 ° and 30 °.
- the viewing angle is advantageously determined at 16 ° to 20 °.
- the rod at a safe distance behind the front 12 of the Thermal insulation 13 of the combustion chamber to end to overheat avoid and keep the pollution as low as possible.
- a representative part of the surface of the grate can be detected.
- sufficient length of the glass rod e.g.
- the optical sensor system 14 can be attached at its end become.
- a flexible fiber optic cable is connected, which together with the Fiber optic cables from neighboring sensors lead to a common housing, in which the sensors of all glass rods are housed.
- the fiber optic cables can be almost any length.
- the diameter of the glass rod 10 is between 1 and 6 mm, preferably between 2 and 4.5 mm. If the glass rod 10 is too thin, it is sufficient the mechanical strength and the amount of light received, it becomes too thick, then it becomes too expensive.
- the length of the glass rod is conveniently between 200 and 600 mm, because - if it is shorter than 200 mm - the cold end is not far from the hot combustion chamber and only a glass rod that is too long is expensive and has no advantage.
- a glass rod 10 is shown as an example in its protective sleeve.

Description
- Dadurch, daß noch brennfähiger Brennstoff in die Asche transportiert wird, geht Brennstoff verloren und es leidet darunter die Wirtschaftlichkeit der Anlage.
- Die dabei produzierte Asche ist mit Kohlenstoff beladen und daher schwierig deponierbar und für eine Reihe von Anwendungsfällen nicht mehr geeignet.
- Meist ergibt sich ein solcher Zustand, wenn die Feuerung mit Maximallast oder mit Überlast betrieben wird. In solch einem Fall wird brennfähiger Brennstoff in die Asche abgeworfen und neuer, meist nasser, Brennstoff nachgeschoben. Dieses hat zur Folge, daß immer mehr nasser Brennstoff in die Feuerung eingebracht wird und dieser erst trocknen muß, d.h. daß ein Teil der erzeugten Wärme für die Trocknung des eingebrachten zu nassen Brennstoffes verwendet wird. Die tatsächliche Leistung der Feuerung sinkt also, was dazu führt, daß die Regelung den Rost mit mehr Brennstoff beschickt. Dieser Vorgang wiederholt sich so lange, bis das Feuer zur Gänze am untersten Rand des Rostes gelegen ist und immer mehr unverbrannter Brennstoff in die Asche geschoben wird, während die Kesselleistung abnimmt bis schließlich das Feuer erlischt.
