Definitions
- the invention relates to a method for controlling a combustion process, wherein at least one substitute fuel in the form of an airworthy fraction is used.
- Piece size and bulk density are dependent on the utilization of the fuel.
- raw waste such as scrap tires, plastics, industrial and commercial waste, as well as animal meal and animal fats, are suitable for use in the refuse-derived fuel industry for use in the cement industry.
- waste oil, solvents and municipal waste are used for treatment, among other things.
- the available alternative fuels are often very inhomogeneous in their material quality.
- impurities such as sulfur, heavy metals and chlorine
- the content of impurities such as sulfur, heavy metals and chlorine
- it is of particular interest to know the content of impurities, such as sulfur, heavy metals and chlorine, of the alternative fuels used.
- impurities such as sulfur, heavy metals and chlorine
- Due to the heterogeneity of the substitute fuels used it is still difficult to obtain reliable information about the material quality.
- appropriately prepared substitute fuels with a certain quality are sold.
- NIR near infrared spectroscopy
- RMA X-ray fluorescence analyzes
- the material composition, the moisture content and the pollutant contents can be analyzed.
- wet-chemical analyzes are also used, but they are very expensive due to the strongly fluctuating composition of the substitute fuels.
- the invention is therefore based on the object to improve the method for compliance with emission limits in a combustion process.
- this object is achieved by the features of claim 1, by the method for controlling a combustion process, at least one substitute fuel in the form of an airworthy fraction is used, wherein at least a part of the substitute fuel is subjected to a vibration spectroscopic analysis and the values determined in the analysis be used to control the firing process.
- a vibrational spectroscopic analysis is a group of analytical measuring methods based on the excitation of the normal vibrations of molecules. These include in particular the Infrared spectroscopy, UV / VIS spectroscopy and Raman spectroscopy. Preferably, however, terahertz spectroscopy is used.
- Molecular spectroscopic analysis methods are particularly suitable for checking the substitute fuel, in particular during its promotion to a combustion zone, especially since it can be done without contact and no further treatment of the fuel is required.
- Terahertz spectroscopy is distinguished from near-infrared spectroscopy primarily by a higher penetration depth, so that overlapping fuel fractions can also be detected.
- the calorific value, the moisture, the carbon content and the chlorine content of the substitute fuel or substitute fuel mixture can be determined in particular by means of terahertz spectroscopy.
- Terahertz Time Domain Spectroscopy is a reliable method for non-contact and nondestructive testing. By examining the fuel or the fuel mixture point by point, images in 2D format (imaging) or even 3D format (tomography) can be obtained in addition to the spectroscopy.
- Terahertz waves are electromagnetic waves in the frequency range between 100 GHz and 10 THz. Many molecules in this spectral region show characteristic signatures in their absorption spectra (chemical fingerprint). In addition, many are transparent to visible light or infrared (IR) impenetrable materials for terahertz waves.
- the terahertz (time domain) spectroscopy is based on the generation of broadband electromagnetic radiation by ultrashort femtosecond laser pulses and on the detection with the pump-probe principle.
- the advantages are a coherent detection of the terahertz waves and thus a high-resolution amplitude and phase recording of the electric terahertz field in the time domain.
- This measurement technique suppresses incoherent radiation, ie there is no interference with room temperature and ambient light.
- terahertz spectroscopy provides information on intermolecular motion.
- the substitute fuel is subjected to the vibration spectroscopic analysis during its promotion via a feed line to a combustion zone.
- any substitute fuel which is due to its composition (for example, a too high chlorine content) should not enter the combustion zone, be prematurely discharged.
- the firing process can be adapted directly to a changing composition of the substitute fuel and an associated burning behavior.
- terahertz spectrometers With terahertz spectrometers, the chemical fingerprint of substances (gases, liquids, solids) can be determined. Measurements are possible both in transmission and in reflection. To investigate powders and liquids, an ATR (Attenuated Total Reflection) arrangement can also be used. The evaluation of the spectroscopy measured values is preferably carried out automatically by means of chemometry. A terahertz spectrometer can also be used to determine the moisture distribution.
- chemical information is extracted from the data of the terahertz spectroscopy by means of chemometric methods.
- Chemometrics is the application of mathematical and statistical methods to reliably extract information from experimental data.
- the basis for automation in a first phase of the training or learning phase is mostly known Substances repeatedly measured under many different conditions. Based on this data, expert systems or databases are subsequently set up.
- the test phase further measurements are taken and tested against the database.
- the goal should be to build up the database as far as possible to include only substance-specific information.
- the non-substance-specific information component has to be removed from the measured spectra. These include, among others, the effects of steam lines and particle scattering.
- the influence of nonsubstance-specific information components can be minimized by a clever sequence of spectral filters. After all measured data have passed through the information-sharpening filter sequence, a property reduction is carried out.
- PCA Principal Component Analysis
- the PCA describes the high-dimensional features in an alternative, orthogonal space: the first major axis is in the direction of maximum variance, the second major axis is perpendicular thereto Often, only a few principal axes suffice to characterize a large part of the information, and then the proportions of the higher major axes are not taken into account, since the representation of the original measurements in the PCA-transformed space often already shows a visible separation of the data Ideally, individual clusters are formed for each substance.
- chemical information is extracted from the data by means of chemometric methods, which information was determined during the oscillation spectroscopic analysis of the substitute fuel.
- the chemical information obtained can then be summarized and classified in a database using self-learning algorithms, with cluster analysis preferably being used for structuring the data or data records.
- the data of the substitute fuel determined during the vibration spectroscopic analysis are compared with comparative data in order to automatically detect anomalies.
- the comparative data can be determined by a vibration spectroscopic analysis of known substitute fuels or known proportions of the substitute fuels.
- parts of the substitute fuel can be divided into different components in advance and examined individually by means of vibration spectroscopic analysis.
- the regulation of the fuel may be to affect the amounts of fuel. If it is determined, for example, that the substitute fuel has too low calorific value, the fuel supply can be increased overall or a higher-value fuel can be supplied with a correspondingly larger proportion.
- the regulation of the combustion process can also consist, for example, in a change in the combustion air or in an adjustment of the flame shape on the burner used.
- the burning process takes place in the context of a cement production process, wherein the combustion zone is formed by a rotary kiln and / or a precalciner.
- the fuel or the fuel mixture is also via at least one burner supplied to the combustion zone.
- the vibration spectroscopic analysis is designed such that in particular the calorific value and / or the humidity and / or the carbon content and / or the chlorine content of the substitute fuel are determined.
- the substitute fuel can be formed for example by sewage sludge or preferably by an airworthy fraction (so-called fluff), wherein the flyable fraction expediently has a particle size of 1 to 5 mm. If the substitute fuel used is relatively inhomogeneous, it is advisable to comminute and / or homogenize the substitute fuel on the feed line to the combustion zone in at least one mill. For this purpose, for example, an intermediate eddy current mill is suitable.
- vibration spectroscopic analysis it is also possible to discharge a part of the substitute fuel on the feed line to the combustion zone and to prepare and analyze it for a second chemical analysis. This is done, for example, when large deviations from the standard or large fluctuations are detected by means of the vibration spectroscopic analysis.
- a substitute fuel 1 in the form of an airworthy fraction via a feed line 2 at least one combustion zone 5 is supplied, which is, for example, a rotary kiln and / or a precalciner with a burner ,
- the substitute fuel 1 is optionally further comminuted and / or homogenized on the feed line 2 to the combustion zone 5 initially in at least one mill 3, for example an eddy-current mill, if this is necessary.
- the substitute fuel 1 should preferably be in the size of 1 to 5 mm for the task in the combustion zone 5.
- the airworthy fraction is, for example, fluffy Wool, flour-shaped fluff or fluff pellets. After pre-shredding, eg in an eddy-current mill, the fluff is in a more homogeneous form. During comminution, the fluff is better mixed and can then be easily transported, analyzed and dosed.
- suitable transport mechanisms such as conveyor belts, scratches, suction conveyor, etc. are provided.
- a first analysis device 4 for a vibration spectroscopic analysis is further arranged, which can be formed, for example, by infrared spectroscopy, Raman spectroscopy or UV / VIS spectroscopy.
- a terahertz spectroscopy is used here.
- Terahertz spectroscopy provides a reliable method for non-contact and non-destructive testing of materials, which is particularly suitable for the substitute fuel of interest here.
- the substitute fuel 1 is automatically detected in fixed time grids by the first analysis device 4, the recorded data being evaluated accordingly.
- Terahertz spectroscopy makes it possible in particular to determine the calorific value, humidity, carbon and chlorine content.
- the determined data of the first analysis device 4 are processed, wherein chemometric methods can be used to extract chemical information from the data.
- the chemical information obtained can then be summarized and classified in particular with self-learning algorithms in one or more databases 9, wherein the cluster analysis can be used for structuring the data or data sets.
- the values determined during the vibration spectroscopic analysis are evaluated in the evaluation device 8 and used to control the combustion process in the combustion zone 5.
- a second fuel 6 is used in the combustion zone 5 in addition to the substitute fuel 1
- the regulation of the Burning process due to the vibration spectroscopic analysis for example, in a change in the ratio of the two fuels 1 and 6 consist.
- the regulation of the combustion process may include a change of the combustion air 7, which is supplied to the combustion zone 5.
- the combustion zone 5 is part of a cement production plant and the regulation of the combustion process can consist in particular of a change in the distribution of the primary, secondary and tertiary air occurring there.
- the control may also include an adaptation of the flame shape.
- a subset of the substitute fuel can be sorted out in advance.
- the rejected substitute fuel is first processed in a processing device 10 ready for analysis samples 11 and then subjected in a second analysis device 12 to a second chemical analysis, for example, one or more of the following analysis methods can be used: X-ray fluorescence analysis, terahertz spectroscopy, elemental analysis, Calorific value determination, etc.
- the determined data of the second analysis device 12 are further processed, in turn, chemometric methods can be used to extract chemical information from the data.
- the obtained chemical information can then in particular be combined and classified with self-learning algorithms in the at least one database 9, wherein the cluster analysis can be used for structuring the data or data sets.
- the values determined in the second chemical analysis are then also used to control the combustion process in the combustion zone 5. They also serve to review and adapt the first chemical analysis.
