Definitions
- the present invention relates to a method for the combustion of materials to be thermally treated, for example household waste according to the principle of direct current firing on a grate of an incineration plant with supply of primary air from below through the grate according to the preamble of claim 1, and a combustion plant for carrying out the method .
- a method for the combustion of materials to be thermally treated for example household waste according to the principle of direct current firing on a grate of an incineration plant with supply of primary air from below through the grate according to the preamble of claim 1, and a combustion plant for carrying out the method .
- Such a method and such a system are known from document A Merz "Industrial furnaces and boilers - Proceedings of the 3rd European Conference", April 18-21, 1995, Lisbon, Portugal, pages 454 to 466.
- residual waste is burned as waste with a relatively large amount of excess air. Theoretically, a little more than 3 Nm 3 of air is required per kg of fuel with a calorific value of approx. 8 MJ / kg. In fact, 6 Nm 3 was used until recently. To date, the specific air consumption figure has been reduced to approx. 5 Nm 3 .
- the object of the present invention is to provide a method which, by means of purely combustion chamber-side measures, enables the NO x components in the exhaust gas of the system to be reduced.
- the invention is based on the knowledge that this can be achieved by reducing the temperatures in the range below 900 ° C. at the end of the combustion chamber in the outflowing flue gas. This task is new.
- the present invention proposes the method steps in a method according to the preamble before, which are specified in the characterizing part of claim 1. Further advantageous features of the invention and the solution to the problem with regard to an incineration plant for the method are set out in the features of the subclaims.
- the zone-by-zone temperature reduction not only a reduction in the specific amount of combustion air but also a flue gas-side temperature of considerably below 900 ° C can be achieved and thus subsequent thermal NO x formation can be prevented in a particularly advantageous manner .
- a secondary air addition for post-combustion, which would increase the flue gas temperatures, is not necessary. It is essential that the invention specifies a controlled temperature field or profile that must be generated in the combustion chamber.
- the exhaust gas is guided through the zones in a precisely defined temperature range by the addition of air into the co-current with the movement of solids on the grate, redirected upwards and back again. Due to the forced guidance of the hot combustion gases, the internals take on the temperature of the gases and also act as infrared emitters, similar to the hot gas body located above the drying zone during countercurrent combustion.
- the fire situation in the DC configuration here is identical to that of countercurrent firing without any further measures.
- the system therefore combines the favorable properties of both combustion processes in a particularly advantageous manner.
- waste is burned on a grate 1 according to the principle of direct current firing.
- the primary air is supplied to the grate from below underwind zones a to d.
- the hot exhaust gas or flue gas 2a - 2e is described later, above the firing grate 1, arranged heat-conducting and - storing internals 3, 4, which can have approximately the same length as the combustion zone 5 of the primary area I, in cocurrent with the movement of solids on the grate 1 positively guided over this in the combustion direction 6.
- the combustion takes place in successively defined zones in their temperatures, which will be described later with reference to FIGS. 2 and 3.
- the hot exhaust gas in the area of the grate end 7 is directed upward around the end of the internals 4 and above the internals 3 in the secondary region II in the opposite direction 2d, 2e over the grate 1, in the embodiment of the system shown in FIG. 1 to its initial area 8, forcibly returned.
- the heat transferred to the internals 3, 4 by this gas recirculation can be radiated from these internals 3, 4 over their entire length in the direction of the grate 1 onto the combustion material and thus be used.
- a shorter one Transmission length over only part of the internals is also possible by moving the outflow opening 12.
- the central element of an exemplary waste incineration plant in which the method is carried out is the combustion chamber 10 consisting of the primary area I and the secondary area II, which is closed at the top by a heat-insulating wall 9 and which is shown enlarged in FIG.
- the details shown in FIG. 2 correspond to those in FIG. 1, the same elements being intended to have the same position numbers as in FIG. 1, even if these are not shown separately.
- the primary area I is the firing grate 1, over which the entire combustion zone 5, consisting of individual zones, is also shown in FIG. 2.
- the combustion of the fired material 11 introduced into the initial area 8 of the grate 1 Refuse is carried out according to the principle of direct current firing, the fired material migrating in the combustion direction 6 or with the combustion up to the ash discharge 14.
- the resulting smoke or exhaust gas 2 flows in the direction of the arrows 2a to 2e in the secondary region II from the combustion zone 5 to the outflow opening 12 into the flue gas flue 13.
- the outflow opening 12 lies in the system form shown by way of example in FIG seen -, approximately above the beginning of the combustion zone 5 on the grate 1 in the upper wall 9 of the combustion chamber 10 behind the secondary area II and leads through this into the flue gas flue 13 above it.
- the outflow opening to the flue gas flue can also - seen against the direction of combustion - be located further forward in secondary area II.
- a heat-conducting and -saving intermediate wall of approximately the same length as the combustion zone 5 which consists of individual ceramic plates 3 and 4 lying one behind the other, which are on the side walls 17 of the combustion chamber 10 attached ledges 15 are placed and which separates the primary area I from the secondary area II.
- the last ceramic plate 4, as seen in the direction of combustion 6, is inclined towards the grate 1.
- the intermediate wall 3, 4 sits tightly between the side walls 17 and the end wall 16 of the combustion chamber 10 and extends, as seen in the combustion direction 6, to approximately the area of the grate end 7 or the combustion zone 5.
- the lower part of the side walls 17, the Primary area I or the combustion zone 5 is assigned, is designated 18.
- the deflection region 2c for the deflection of the flue gases 2a, 2b in the opposite direction 2d and 2e is now - again seen in the combustion direction 6 - via the intermediate wall 3, 4 to the outflow opening 12.
- the secondary area II. B. from an Al oxide ceramic and have a thickness of 25 to 35 mm with a grate width of 80 cm. They have a high heat transfer coefficient in order to ensure good heat transfer through them from the exhaust gas area 2d, 2e and then further by means of heat radiation back into the combustion zone 5.
- the desired temperature profiles are achieved in that the primary air is fed zone by zone from the underwind zones a, b, c, and d through the grate, the air quantities for zones A and B being metered in such a way that substoichiometric combustion takes place in the material bed . Due to the lack of oxygen on the primary side During combustion, considerable amounts of CO in the order of 100 g / Nm 3 are released from the material bed in this area, which in turn have a reducing effect on NO x that has already formed, as a result of which elemental nitrogen is formed. In addition, a large number of radical reactions can occur, which in turn can influence the NO x reduction.
- the sub-stoichiometric fire control can be carried out either by increasing the fuel addition or by throttling the air volume from the underwind zones.
- the side wall or walls of the combustion chamber predominantly or only in the area of zones A and B of the combustion chamber 10 below the internals 3 and 4, i.e. in the combustion chamber above the grate 1 additional air, the so-called fog air 20 of lower or approximately the same temperature is added to the combustion chamber temperature in the combustion chamber.
- This additional air thus forms an air curtain in the wall area.
- the fog air supports the gas phase reaction in zones A and B. It is important that in the area above the internals 3 and 4, in the secondary area II i.e. no further secondary air is added after the fourth zone D.
- FIG. 4 a section through a side wall of the system at the level of the furnace 10 is shown in FIG. 4.
- a cooling air duct 19 runs through the side wall 17, through which cooling air 22 is guided in a direct current to the combustion direction 6 by means of fans, which are no longer shown, for cooling the side walls with a certain excess cooling air pressure.
- This side wall 17 is designed to be air-permeable in the partial area 18 located next to the primary area I between the primary area I and the channel 19, so that fog air 20 can escape from the channel 19 into the primary area I.
- the air permeability can be achieved through porosities, small channels or other passages 21.
- the portion 18 of the side wall 17 with the Porosity or the openings is preferably or predominantly only in the area of zones A and B.
- the fog air 20 can be dosed as desired.
- the temperature of the curtain air is determined by its heating up in the wall.
- the primary area I is bounded at the bottom by the grate 1, at the top by the ceramic plate internals 3 and 4, and on the sides by the lower side walls 18 in the form of the combustion chamber lining.
- This side wall 18 in the primary area I has, as already described, a defined air permeability for the passage of the air 20 in whole or in part.
- the air permeability can be achieved by a uniform, specific and adjustable air passage rate of the wall itself or individual wall parts. This is particularly favorable in the case in which the veil air 20 is taken from the cooling air 22 cooling the side wall 17 from the outside. however, the fog air 20 can also be supplied through one or more openings in the wall from other sources.
- the temperature profiles of the new method are shown graphically over the individual zones in the lower part and further characteristic values of the combustion in the upper part. These are measured values from a test that was carried out in a waste incineration plant.
- the curves with the round measuring points show the temperature profile in primary area I, ie in zones A, B, C and D at measuring points T70 to T75, the curves with square points at measuring points T105 to T107 in the exhaust gas flue.
- the full points show the temperature profile without the addition of the fog air 20, the hollow points show the profile desired with the addition of the fog air 20 in the process according to the invention. It is clearly shown that the required temperature reduction the rear zones C and D is reached. Volume ratios of approximately 1/5 to 1/6 of air to primary air (ie approximately 14-17% of air in the total air) have proven to be particularly favorable at the combustion temperatures and air temperatures of approximately 500 ° C. to 750 ° C. shown.
- zones A, B, C and D of primary area I as already described above, all processes such as drying, degassing, gasification, sintering reactions and gas phase reactions take place above the material bed.
- a usual gradation of the primary air addition from the underwind zones a, b, c and d in the tests according to FIG. 3 is at a fuel throughput of approximately 170 kg / h: 100 Nm 3 / h in zone A and D and 200 Nm each 3 / h in zones B and C.
- the aforementioned air of 100-120 Nm 3 / h is now passed through the side wall 18 that delimits the combustion chamber lengthways mainly fed into zones A and B. Due to the way of guiding through the hot walls, the veil air enters the primary room I at the desired temperatures of 500 ° C to 750 ° C, the temperature in this area being specifiable by air-side measures.
- the secondary room II directly adjoins the primary room I. As already stated, no further combustion air is fed into this secondary space II. For the chemical reactions taking place there, e.g. B. the remaining CO conversion, the oxygen offered by primary and fog air is sufficient.
