Definitions
- the invention relates to a method for the cooling of with cooling channels provided parts of a Feuerungsrostes, the be heated during operation of the Feuerungsrostes can.
- the invention relates to a furnace grate for a combustion plant for carrying out the method.
- DE 808263 C is still a rust for the combustion of solids discloses, in which a waste heat boiler is connected downstream, over a Feedwater line with feedwater pump and feedwater control valve Feed water is supplied. This will be additional pumping systems superfluous.
- the object of the invention is a simple method for better Cooling a firing grate of an incinerator to create and cooling a firing grate in a plant to burn Feststeffen to improve.
- this is achieved in a method according to claim 1, with a portion of the feedwater after the feedwater pump and before the Feedwater control valve removed from the feedwater line and under Use of a defined pressure reduction is fed to the cooling channels, the control of the pressure of the cooling water and the Flow rate in the cooling channels is set so that the Cooling water when flowing through the cooling channels to saturated steam temperature is heated and thus a part of the cooling water is evaporated and subsequently supplied to a customer is to improve in an antitank to the burning of Feststeffen and then a customer.
- the cooling channels have a comparatively small inner diameter, whose maximum size is designed so that no segregation of water and steam takes place, and that the lines to the cooling channels, which moved in Rostbelagin opposition lie, tubes are with an inner diameter, which is less than the inner diameter of the cooling channels, and wherein the Supply lines between feedwater pump and feedwater valve with the Feed water line are connected and in the supply lines at least one Valve is arranged, which controls the amount of cooling water to be supplied via a automatic temperature control system regulates.
- This grate has the advantage that it has cooling channels having small diameter, which in larger numbers with uniform distribution within the grate bar and the further rust parts can be poured. Another Advantage is that the cooling system with little Water is operable, since all the sensible heat and a Part of the heat of evaporation can be used.
- cooling water / steam mixture a Steam separator is fed, the vapor deposited in the drum is passed and the remaining saturated water in the feed water is returned. In addition, it can be used to preheat the cooling water.
- a pressure drop is generated in the cooling water, which is at least 1 ⁇ 4 of the pressure drop between the exit from the feedwater pump and the entrance into the drum. In this way, an approximately constant in all cooling circuits Cooling water flow reached.
- Fig. 1 shows a longitudinal section of a schematically illustrated Waste incineration plant, which essentially consists of a water-cooled Combustion grate 1, an overlying combustion chamber 2 and a downstream boiler 3 with vertical Leermann 4 and a horizontal Bundle 5 consists.
- the kiln 6, in this case waste, is on the grate 1 abandoned and burned with supply of primary air 7 and secondary air 8.
- the Resulting flue gases 9 enter the boiler 3, they flow under Release of heat through the vertical empties 4 and the horizontal Bundle 5 of the boiler 3 and then one not shown Flue gas cleaning system supplied. In that regard, such systems are known.
- Fig. 2 shows a schematic representation of the cooling system of water-cooled grate 1 with downstream boiler 3 in a first Embodiment variant of the invention.
- the grate 1 consists essentially of several rows (10.1, 10.2, 10.3 ...) arranged side by side Rostbelagin whatsoever 11.
- Fig. 2 are an example of a thermally highly stressed Row 10.1 and two thermally low loaded rows 10.2 and 10.3 are shown, where the 10.2 series has a fixed grate coating unit row and row 10.3 is to represent a moving row of grate units and the two rows 10.2 and 10.3 are connected by a flexible connecting line 38.
- the Rostbelaginiganudge 11 may be narrow grate bars or wider grate plates. Adjacent rows overlap each other like a tile. It can be longitudinally be arranged alternately moving and fixed rows of the grate or all rows can be moved.
- the grate 1 also has side walls 12 on.
- the cooling channels 14 are preferably in the Rostbelagin institution 11 cast-in coils, which with supply lines 16 and discharge lines 17 are in communication, the Lines 16, 17 are thin tubes, each having a stretch circle 18th can have.
- the cooling channels 14 have a comparatively small Inner diameter, for example 14 mm.
- Inner diameter of the supply lines 16 is substantially lower than that Inner diameter of the cooling channels 14, for example 8 mm.
- Inner diameter of the discharge lines 17 is because of the forming Vapor phase slightly larger than that of the supply lines 16, but still much smaller than the diameter of the cooling channels 14 in the Grating units 11.
- each supply line 16 are a three-way valve 19 and at least one Valve 20 installed.
- the supply lines 16 all branch off from a line 21, which in turn branches off from the feedwater line 22, in which boiler feedwater 23 from Feedwater tank 24 via the feedwater pump 25 and the Feedwater control valve 26 via the economizer 27 into the drum 28 of the Boiler 3 is passed.
- the branch of the line 21 from the line 22 takes place doing so after the feedwater pump 25 and before the feedwater control valve 26th
- the discharge lines 17 of the cooling systems each have check valves 29 and open into a manifold 30, which to the drum 28 of the boiler. 3 connected.
- the drum 28 is further provided with an evaporator 31 and a superheater 32 with a water injection 33, which via a Injector 36 is controlled, in conjunction.
- the cooling system of the grate consists of several parallel connected Subsystems.
- Fig. 2 are exemplified a subsystem for cooling the side walls 12, a subsystem for cooling a RostbelaginRICRIA 10.1 in the thermally highly stressed part of the grate 1, a subsystem for the Cooling of two rows 10.2 and 10.3 of grate in thermally lower loaded part of the grate 1 and a subsystem for the cooling of the central beams 13th
- cooling water 15 is used, which is a partial flow of demineralized degassing feedwater 23 for the operation of the boiler is 3.
- This cooling water 15 bypasst the economizer 27, it is after the feedwater pump 25 and before the feedwater control valve 26 is removed from the feed line 22 and flows via the line 15 in the supply lines 16 of the parallel subsystems of the Cooling system.
- the grate cooling is thus parallel to the economiser operation.
- cooling water 15 stands for the grate cooling always enough water available, which also a flawless Quality and sufficient pressure.
- throttle valve 20 causes a pressure drop, which at least 1 ⁇ 4 of the pressure drop between the exit from the Feedwater pump 25 and the entry into the drum 28 is.
- the cooling water 15 is in the cooling of Rostbelagajien 11, the Side walls 12 and the center bar 13 at least close to the Saturated steam temperature heated. Normally, the cooling water is 15 down to the Saturated temperature heated so that a portion of the water 15 evaporates.
- the Cooling water can also be completely or to a large extent (steam content> 0.3) evaporate, d. H. the cooling takes place according to the single-pipe boiler principle.
- the heated cooling water or water / steam mixture over the lines 17 in a manifold 30 and from there into the drum 28th guided.
- the cooling is thus at a pressure and temperature level, the only slightly above the drum 28 is located. The advantage is that the delivery of the dissipated amount of heat in the drum 28 is always possible.
- a temperature control system TCA measures the outlet temperature of the heated cooling medium in line 17. The corresponding signals are directed to the valve 20, which depends on the respective Temperature level, the amount of the supplied cooling water 15 controls, d. H. at a high temperature value, the valve 20 will open further, so that more Cooling water 15 is passed into the respective cooling channels 14 than at a lower temperature. In this way, the cooling can be optimized in which case slightly superheated steam is generated (single-tube boiler principle).
- Fig. 3 shows a schematic representation of the cooling system of a water-cooled grate with downstream boiler. This differs from that in FIG. 1 shown and described above only in that as Pressure drop points 20 apertures are used. Similarly, thin tubes or manually operated needle valves can be used.
- the heated cooling water or the resulting during cooling to pass steam to another customer.
- Fig. 4 shows a variant of the invention analogous to FIG. 2 at which as a buyer of the heated cooling water 15 and the water / steam mixture not the boiler 28, but the feedwater tank 24 acts.
- the customer is the Air preheater (Economiser 27) or as shown in dashed lines, a District heating supply device 34.
- the resulting vapor pressure can be lower be as the drum pressure, which is advantageously a deeper Grate unit temperature causes.
- the manifold 30 in a vapor separator 35th to lead, so that the water / steam mixture enters the vapor separator, the separated steam then into the drum 28 of the boiler 3 to guide and the remaining saturated water in the feedwater tank 24th attributed, which thus additionally the cooling water 15 via a Heat exchanger 37 can be preheated.
