- a plant is also to be specified with which a burn- tion of the material is achieved with high efficiency, in particular, a targeted post-combustion of the material on the device for the promotion and treatment of material should be made.
- a method for conveying and treating hot ash of a combustion boiler is to be specified, with which also the above-mentioned objectives can also be achieved at least in part.
- the device according to the invention for conveying and treating material from a combustion boiler has at least one conveyor belt and a housing surrounding the conveyor belt, wherein the conveyor belt has at least one horizontal catchment area and a treatment area and the housing has at least one outlet for the material. Furthermore, the treatment area has a first length of at least 10 m (meters) and a slope of at least 38 ° (degrees).
- the device is one which realizes a so-called “dry” transport of the material from the combustion boiler.
- especially ash meant (directly) from the burning Kessel be abandoned on the conveyor belt.
- the material has a temperature in the range of about 600 0 C to 1000 0 C, in particular in the range of 800 0 C.
- the "combustion boiler” may, for example, be one of the following: lignite combustion boiler , Hard coal combustion boiler, waste incinerator.
- the conveyor belt is preferably carried out in the manner of a steel plate conveyor, in which a plurality of steel plates are mutually (minimally) overlapping articulated in series and moved by drives or pulleys.
- a steel plate conveyor in which a plurality of steel plates are mutually (minimally) overlapping articulated in series and moved by drives or pulleys.
- As a material for the conveyor so in particular impact-resistant, corrosion-resistant and temperature-resistant steels come into consideration.
- This conveyor belt is surrounded by a housing.
- the housing is usually designed so that it can be positioned directly on a corresponding platform and attached if necessary.
- the conveyor belt is positioned and fixed aligned.
- the housing has regularly connection hatches, for example, to the combustion boiler.
- at least one outlet for the material is provided.
- even smaller passages for inspection, cooling and / or adjustment of the conveyor belt can be provided.
- this housing is regularly made of steel and suitable to permanently withstand the environmental conditions described above.
- a horizontal catchment area is regularly located below the hatch for the combustion boiler and serves to pick up the material from the top of the conveyor belt.
- a substantially horizontal orientation of the conveyor belt is proposed.
- first length which is at least 10 m. It is very particularly preferred that the first length is greater than 30 m or even at least 50 m. In this context, it is also preferred that with smaller pitches given here, a greater length is preferable, and vice versa.
- the first length of the treatment area is determined in particular along the extension direction of the conveyor belt. The first length of the treatment area has particular effect on the achievable cooling distance and the length of the transport of the material without a complete reorientation of the material on the conveyor belt itself. In this respect, the aim here is to realize a particularly large first length.
- the treatment area has a slope of at least 38 °, preferably a slope of at least 42 ° or even to 45 ° relative to the horizontal.
- the pitch proposed here it is achieved, for example, that straight large and / or elongated material chunks are brought into an unstable position during the conveyance and thus in particular deliberately slip off these large chunks of material again, possibly bursting or even bursting the other side can be cooled or treated.
- the slope has the advantage that targeted hotter can be separated from colder material at the inlet to the treatment area and / or a targeted portioning of the material to be treated or a uniform distribution of the material can be achieved via the conveyor belt can.
- the treatment area is arranged with a maximum distance of 5 m (meters) towards the end of the collecting area.
- the catchment area has an extension of, for example, 5, 8 or a maximum of 10 m, with ash being discharged from the entire bottom of the combustion boiler.
- this catchment area may be e.g. also be up to 20 m or even 30 m long.
- the lowermost layers have regularly achieved a solidification by their direct contact with the conveyor belt to a greater extent, it is now to be feared that the above hot material interferes with this process. For this reason, it is now proposed to quickly move into the treatment area, in particular, a uniform distribution or redistribution of the hot material takes place. It is therefore particularly preferred for the treatment area to start, if appropriate, with an even smaller distance towards the end of the collecting area, for example with a maximum distance of at most 3 m or even at most 1.5 m.
- the collecting area and the treatment area are connected via a deflection region, wherein the housing forms a reservoir of material in the deflection region above the conveyor belt.
- the "diversion area” usually represents the transitional section of the derbandes from the horizontal orientation to the inclined orientation.
- the deflection is characterized for example by corresponding deflection rollers on the conveyor belt.
- the deflection region in particular, there is a radius of curvature for the conveyor belt, while in the collecting area and / or in the treatment area, a substantially straight course direction for the conveyor belt can be established.
- the housing allow sufficient space for such material accumulation on or above the conveyor belt.
- “reservoir” is thus meant, in particular, a portion of the housing which is substantially free of internals and / or even forms a greater clearance above the conveyor belt. or a separate cage to guide the resulting material clusters.
- the conveyor belt is designed with at least one of the following characteristics: a width of the conveyor belt of at least 0.80 m (meters), webs running along the width with a web height of at most 200 mm (millimeters ), along the extension of the conveyor belt with a distance of at least 0.65 m (meters) arranged webs which extend along the width.
- the width of the conveyor belt which is regularly determined perpendicular to the direction of extension of the conveyor belt, is thus greater than that of current designs. tions of the conveyor belt is performed. In particular, a width of at least 1.20 m or even 2.40 m is to be realized.
- the width given here has particular advantages in the distribution of the material on the conveyor belt, once in the task of the material from the combustion boiler and on the other hand in the redeployment of the material in the treatment area and / or in the deflection. In particular, the ranges of the width between 0.80 m to 1.20 m or 1.20 m to 2.40 m are particularly preferred.
- the aim is to distribute the material in particular across the width of the conveyor belt and thus to achieve a good contact with the (cooler) conveyor belt and a large surface area for contact with a cooling air flow.
- webs may be provided which extend substantially across the width of the conveyor belt.
- the webs limit the movement of the material due to gravity in the treatment area and thus can contribute in particular to the portioning of material in a specific segment of the conveyor belt.
- the webs may for example be in the form of vertical and / or inclined metal plates which are mounted (in particular rigidly) on the conveyor belt, for example welded to plates of the conveyor belt.
- the ridge height should not be too high. Therefore, it is proposed here that the web height is limited to 200 mm (millimeters), wherein it should preferably not be less than a minimum web height of about 100 mm.
- the distance of the webs is to be chosen in an advantageous manner such that a sufficiently large surface is provided for the material to be treated, wherein the distance may under certain circumstances also be at least 0.80 m or even at least 1.20 m.
- this surface segments of the conveyor belt are limited, with a relatively large area is provided for the material to be treated, the layer height of the material, however, is very limited. Excess material will then roll over the webs into the next segment due to the slope of the treatment area, if sufficient surface is still available or the material has burst during the rolling movement.
- this optionally with different web height and / or distance from each other can be performed, in particular, if at least one web has an additional and / or different function, such as a driver for large chunks of material, as a cleaning scraper below the conveyor belt, etc.
- an air supply for an air flow to the treatment area of the device is provided in the region of the at least one outlet.
- the air supply is thus to be set up or positioned so that an air flow in the manner of a counterflow to the transported material can be realized.
- the air supply may include one or more nozzles, slots, openings, or the like, with active (positive pressure) and / or passive (ambient pressure) provision of air generally possible. It is preferred that the air supply comprises one or more openings in the housing, so that in particular due to the negative pressure in the combustion boiler air from the environment (passive) can be sucked. It is further preferred that this air flow is used for the superficial treatment or cooling of the material.
- the air supply in the area of the outlet represents the predominant air supply for the air flow, ie, in particular in the area of the treatment area, there are no additional air supplies for an air flow above the material. So that a finally high temperature of the air flow is achieved over the relatively long treatment area and the provided there large surface of the material, for example a temperature on entry into the combustion boiler above 200 0 C, for example about 250 0 to be achieved, C. This relatively strong heating of the air flow over the large area distributed material also leads to a comprehensive combustion of the remaining components of the material and equally, the energy gained thereby can be reused via the combustion boiler or the subsequent heat exchanger of the combustion boiler.
- the ratio of amount of air per amount of material should preferably be in the range of 1.6 to 2.3, in particular the ratio of the 2 tons (eg air volume approx. 6 t / h and ash quantity approx. 3 t / h [tons per hour]).

- Cross beams extend substantially in the width direction of the conveyor belt, below the upper portion of the conveyor belt to which the
- the cross members in particular have a support function, so that an undesirable deformation of the conveyor belt is avoided even when large material chunks.
- the cross beams can be designed in the manner of beams and / or plates.
- the conveyor belt is connected to a chain drive.
- a chain drive is understood here that the conveyor belt, in particular on both sides, is connected to a circulating chain.
- the chain runs, for example, via a gear, which is driven by a corresponding motor.
- This is realized in particular a rigid and direct drive of the conveyor belt.
- the chain drive has the advantage that there is little slip between the drive movement and the movement of the conveyor belt.
- the chain can be designed with a considerable tensile strength and is therefore particularly suitable for driving high loads. Therefore, this drive is ideal for the long treatment areas.
- such a chain drive is also relatively robust against the changing temperature influences.
- the chain drive is designed with a motor or with a control on which a simple and stepless variation of the drive speed or the speed of the conveyor belt can be set.
- the conveyor belt itself can also still, for example in guides of the housing, are guided, for example, lateral support rollers can be provided.
- the treatment area of the device has different slopes.
- the provision of a conveyor belt having a range of treatment of varying pitch may also be employed independently. It is thus specified in particular that a first slope is first realized, but then this is varied in at least one subsequent section, ie it is enlarged and / or reduced. Under certain circumstances, it is also possible for a section with a slope to be followed by another section with a horizontal position and / or a negative gradient (gradient). It is very particularly preferred that at least two of the elements gradient, horizontal, gradient alternate repeatedly. Thus, an (additional) movement is introduced into the material, so that an improved post-treatment is possible.
- a system which has at least one combustion boiler with at least one base hatch for dispensing material and at least one device of the type described here according to the invention, wherein the catchment area is arranged below the at least one bottom opening and below the outlet at least one silo for the material is provided.
- a “silo” is understood as meaning a reservoir for the material, for example with a capacity of at least 400 m 3 of the material, in particular 900 m 3. It is very particularly preferred that the silo is arranged above the collecting area of the conveyor belt.
- At least one crusher for the material is provided between the outlet of the housing and the at least one silo.
- known mills and / or breakers may be provided, which may be interpreted smaller, since the funded and cooled material usually already has a relatively small size due to the treatment described above.
- data acquisition means are provided at least in the combustion boiler or in the device, which are connected to a controller which is connected to a drive of the conveyor belt.
- data acquisition means is meant, in particular, sensors, for example sensors for determining constituents of the combustion gases in the combustion boiler and / or in the device, temperature sensors or the like
- sensors for example sensors for determining constituents of the combustion gases in the combustion boiler and / or in the device, temperature sensors or the like
- the amount of material per time, the residual content of combustible material and / or the distribution of the material on the conveyor belt can be determined
- it can also be ensured that with different speeds of the conveyor belt, even at high load of the combustion boiler, it is possible to ensure that the drive is moved faster and slower distributed material is discharged with low layer height, the required discharge capacity is met.
- a method of conveying and treating hot ash of a combustion boiler comprises at least the following steps: a) application of the hot ash from a combustion boiler to a horizontal catchment area of a, arranged in a housing, B) shifting the hot ash so that at least a portion of the ash is retained with a shorter residence time in the catchment area, c) transporting the ash in an inclined treatment area having a first length of at least 10 m (meters) and with a slope of at least 38 ° (degrees), whereby an opposite air flow is generated for cooling the ash, d) discharging the ash from the housing.
- the method can be carried out in particular with the device and / or installation described here.
- step a) expresses that hot ash is not deposited on a narrow local area of the catchment area, but rather over a wide portion of the catchment area.
- hot ash deposited on the catching area and subsequently passing through the entire catching area in the direction of travel of the conveyor belt is subsequently covered by further hot ash, which eventually remains in the catching area for a shorter dwell time until it reaches the end of the catching area has reached. Consequently, the ash, which is transported in the collecting area with only a short residence time, is positioned on top of the ash, which has already been fed onto the conveyor belt and in particular is thus cooled directly from the cool conveyor belt.
- step b) a rearrangement of the hot ash is now carried out.
- the last abandoned ash which thus has remained with a shorter residence time in the collecting area and thus rests on top, is now at least partially rearranged, so that in particular the entry is delayed in the inclined treatment area.
- This switching occurs especially in the deflection of the conveyor belt by the hot ash in an unstable position is brought and the top resting or the big ash chunks slip due to gravity or roll over the webs.
- stable positions of the ashes are sought, as well as a uniform distribution of ash over the conveyor belt or a crushing of the ash chunks as a result of these movements (impact, friction, etc.).
- step c) The ash is then removed in the inclined treatment area upwards (step c)), wherein an opposite air flow for cooling the eyes A is generated.
- This air flow thus flows against the transport direction of the ash and is brought into contact in particular with the surface of the hot ash. Due to the low layer height, e.g. At most 200 mm (millimeters) or even only 100 mm (millimeters) of the ash, the air flow can cool particularly well the ash and / or possibly also exposed areas of the conveyor belt, wherein the air flow takes the temperature and heats up relatively high finally in the Burning boiler can occur.
- step d) The omission of the ash from the housing according to step d) takes place in particular solely due to the gravitational force.
- the method proposed here is also considered advantageous that at least during steps b) or c) a portioning of the hot ash is made.
- the amount of hot ash to be discharged is substantially the same according to the load conditions of the combustion boiler, so that the distribution and / or cooling of the hot ash on the conveyor belt in the treatment area can be selectively adjusted.
- large widths of the conveyor belt and / or webs and / or variable drives of the conveyor belt are used for such portioning.
- step d) crushing the ash and storing the ash in a silo This is Specifically, it means that the discharged ash falls directly into a crusher due to gravity where it is optionally ground and then falls (also due to gravity) directly into a silo where the ash (essentially completely solidified) can now be stored.
- the extensive silo and the already stored solid ashes complete the cooling function for possibly not completely solidified hot ash, which has just been omitted.
