Definitions
- the invention relates to a furnace with liquid-cooled Grate elements, each with an inlet and have a return line for a coolant.
- Liquid-cooled, especially water-cooled grate elements for combustion grates have long been from the WO 96/29544 A1 and DE-PS 624 892 known.
- From the first Document is the arrangement of an open to the atmosphere Container known, but only a connection of the return allowed to the atmosphere. The lead, however, is over fed a feed pump, reducing the pressure of the coolant in this area, as well as on the flow rate, through the work of this feed pump as well as that of this pump downstream control valves is determined.
- the second Document discloses a firing grate in which the top At the end, a container open to the atmosphere is provided is, but this container does not serve as a condensation device, but allows the discharge of low pressure steam into the atmosphere.
- the degree of cooling of the cooling medium with this combustion grate is more or less random, since you can see the volume flow of the primary air, which as Recooling medium for the coolant is not used arbitrarily can vary.
- the primary air supplied must the combustion process on the grate orientate and can therefore by no means a defined condensation any water vapor formed in the circulation system cause.
- a disadvantage of more modern combustion plants is the fact that a relatively large, control engineering Effort must be made on the one hand adequate cooling of the grate elements and on the other hand the necessary safety in the event of excessive heat to ensure the grate elements.
- the object of the invention is to provide a furnace with Cooling system for the grate elements to create that for the circulation of the coolant without a control device and without a delivery device gets along and on top of that no facilities for maintaining safety with regard to overpressure are necessary.
- This task is carried out on the basis of a furnace system Initially described type solved according to the invention in that the inlet and the return with an open to the atmosphere Condensation device communicates that in the inlet a U-shaped coolant supply is arranged, the one leg has a liquid height that one arbitrarily selected maximum pressure in the system and that the other, shorter leg with a central distributor is connected for the individual grate elements.
- a particularly preferred embodiment, in particular operational safety is characterized in that the upper end of the shorter one connected to the central distributor Thighs by a chosen safety height the lowest point of the coolant flow of the deepest grate element lies.
- the condensation device open to the atmosphere ensures that even with complete evaporation of the coolant no higher pressure arise in the circulation cooling system may be due to the liquid height of the longer leg the liquid supply is predetermined, which can be freely selected is.
- the distance between the lowest flow level the deepest grate element and the upper one, with the Central distributor connected end of the shorter leg is referred to as the safety height measure and gives the liquid height on in the U-shaped liquid reservoir Pressure that creates a reverse flow in the cooling system counteract, even if locally strong Heat radiation on a grate element in this by evaporation the coolant is strongly blistered.
- this safety height dimension is used for safety reasons chosen so that it is twice the value of the height difference of an inclined grate between the highest and the lowest point of coolant flow in corresponds to this firing grate.
- the invention of the return a central collector for the individual grate elements connected in parallel in terms of flow of the grate steps, which is below the grate elements and in the longitudinal direction of the grate with a along the length of the entire firing grate constant height distance is arranged, which is less than the safety height dimension is.
- the arrangement of both the central distributor and the central collector with a height distance to the firing grate is therefore less than the safety height dimension provided because operational changes it may make it necessary to change the safety height dimension. Even in such a case, it should be ensured that the central collector and the central distributor have less Have a height distance to the firing grate than this corresponds to the safety height dimension.
- This central collector and central distributor are permanently installed and can be installed in the You can hardly change the height afterwards, which for the Connection to the shorter leg of the U-shaped coolant supply, which defines the safety height distance, does not apply to this extent.
- the grate elements have relatively little coolant absorb, but a certain liquid reservoir is necessary is still sufficient in case of excessive evaporation Having coolant available is another advantageous embodiment of the invention provided that the second short leg of the U-shaped coolant supply has an additional storage volume for coolant.
- the short leg of the U-shaped coolant supply is designed as a container into which the longer, dips thinner in diameter and up to close to the bottom of the short leg extends that the upper closed End up just below the lowest point of the deepest Coolant flow of the deepest grate element is sufficient and that a junction to the central distributor below the highest Point of the container goes off.
- the cylindrical container is higher than the geodetic height corresponds to the short leg, i.e. the cylindrical Container extends beyond the branch to the central distributor.
- the entire coolant present in the cooling system can be traced back, is in further development of the invention Central collector starting from its lowest point over a Line connected to a condensate collector. From here, the coolant can flow back into the system be introduced in that the condensate collector via a pump and a line with the condensation device connected is. It is particularly useful that the line according to the invention with a spray nozzle opens into the condensation device.
- the condensation container is provided with a cooling device, then the condensed cooling medium in cooled form in the condensing device to be led back.
- Condensation device as a surface condenser water-cooled heat sinks and a switchable wet condenser is trained.
- the switchable Wet condenser is through the spray nozzle formed by which cooled condensate from the condensate collector is sprayed.
- This wet condensing device which is in the condenser recirculated steam condenses on the cooled water droplets, in a way provides the coolant circuit even if the water-cooled pipes of the Condensation device should be subject to a fault.
- Condensation device can be shut off from the atmosphere and can be connected to a vacuum source the cooling system of the furnace in a particularly simple manner be put into operation.
- the cooling system of the furnace in a particularly simple manner be put into operation.
- the same negative pressure in the central collector generated, causing the coolant according to the pressure drop flows from the grate elements to the central collector, this start of flow is supported by that so-called in the furnace above the furnace grate Start-up burners are ignited which emit heat effect on the grate.
- the Cooling medium located in the grate elements is heated and possibly even evaporates, making the cooling system like a Gravity heating gets moving.
- a grate 2 In a total of 1 designated firebox is a grate 2 arranged, the five in a row, from next to each other grate elements built up, grate steps 2.1, 2.2, 2.3, 2.4 and 2.5, which is roof tile-like overlap and are inclined so that the rear end of the Firing grate, on which a discharge roller 3 is arranged, is lower than the feed point 4 for the fuel.
- the single ones Grate levels 2.1 to 2.5 are water-cooled. For this are these individual grate levels with one serving as an inlet Central distributor 5 connected via supply lines 6 to 10.
- Coolant is usually supplied via these lines Water supplied to the individual grate levels, whereupon the Reflux takes place via drain lines 11 to 15, each have a throttle 16 to 20 to in the central distributor 5th and the individual grate elements to be cooled have a system overpressure build up.
- the drain lines 11 to 15 open into a central collector 21 serving as a return, from which from a line 22 to a condensation device 23 leads.
- Coolant supply which is designed as a U-tube is the longer leg with 26 and the shorter one Leg with 27 is referred to, which as a liquid reservoir serves and a much larger diameter than that longer, thinner in diameter, leg 26, the in this serving as a container for storage liquid immersed in the shorter leg and briefly over the bottom 28 of which extends.
- a connecting line 29 to Central distributor 5 forms the upper end of the shorter leg 27 of this U-shaped coolant template 25.
- the shorter leg which also forms a container 27 at the same time Connection point of the connecting line 29 upwards extended. This part of the container 27 is designated 30.
- Both the central distributor 5 and the central collector 21 are arranged below the grate 2 and have the same inclination as the grate so that the respective The same pressure is applied to grate elements become.
- a condensate line goes from the lowest point of the central collector 21 31 out to a condensate collector 32 leads that at its lower end with a cooling device 33 is equipped.
- a cooling device 33 Starting from the bottom of the condensate collector 32 the condensate by means of a Pump 34 via a line 35 to the condensation device 23 where it is pumped through a spray nozzle 36 into the condenser 23 is sprayed.
- they are from one Coolant flowing through the condenser cooling tubes schematically indicated, their inflow with 38 and their Process is designated 39.
- the cooling system i.e. the individual grate elements through which the coolant flows the central distributor 5, the coolant reservoir 25 and the Condensation device 23 to something over the connecting line 24 filled up.
- the condensing device 23 which during the usual Operation is open to the atmosphere, temporarily closed and connected to a vacuum source via a line 40.
- the upper one is not filled with liquid Steam room 23.1 under a certain negative pressure.
- the start-up burner ignited in the firebox, but none yet Fuel is on the grate 2, so there is heat radiation on the grate.
- the grate and thus the coolant present in the grate elements Heat applied until the temperature of 96.72 ° C.
- the coolant reservoir 25 is dimensioned so that one has a longer and a shorter leg of a U-tube, being the distance of the top point of the longer one Leg, which is caused by the liquid level in the condensation device 23 is formed above the lowest Point of the coolant flow of the deepest grate element 2.5, 4.85m is by no higher pressure in the system than 0.5 to be created in cash, otherwise the system is subject to the steam boiler regulation fall and then build up again would become more complex.
- the height difference between the lowest point of the coolant flow in the deepest grate element 2.5 to the top of the shorter leg, which is formed by the connecting line 29 corresponds to one Safety height dimension, which is chosen in a preferred manner is that there is about twice the height difference between the highest coolant flow point of the top grate element and the lowest coolant flow point of the lowest Rust element corresponds.
- This safety height measure gives a water column and therefore a certain pressure, which is sufficient to withstand the strongest steam development in any of the rust elements To counteract pressure so that there is never a reversal of the Flow direction of the coolant flow can occur.
- the second shorter leg than one in diameter to make the container thicker than the longer leg, in order not only to form a U-shaped pipe system to be able to take up the thinner leg, but also to form a certain fluid reservoir, for what in particular the one projecting upwards over the connecting line 29 Part 30 of the container 27 is used. Because the condenser 23 to atmosphere during normal operation is open, no higher pressure can be in the cooling system arise as a result of the height of the water column of the longer Thigh above the lowest point of the coolant flow of the lowest grate element is specified.
- This height that is freely selectable, determines the maximum pressure in the system, while the distance between the deepest coolant flow the lowest grate element to the connecting line 29, that is to the upper point of the shorter leg, that fluid pressure generated against the resulting in the grate elements Steam bubbles have to work and have to be overcome to be able to force a reversal of the coolant flow. Due to the selectability of this safety height dimension the back pressure can be set so high that even at the maximum heat to be expected on a grate element such a volume of steam with appropriate pressure cannot arise.
