Definitions
- the invention relates to a method for regulating the Fire performance of incinerators according to the generic term of claim 1, and a device for controlling the fire performance of incinerators according to the generic term of Claim 11.
- DE OS 39 04 272 A1 is concerned with an improvement of the combustion process on the grate and strike this Purpose of a detector device in the form of several thermographic or infrared cameras, which are those of the good bed temperature corresponding radiation detected individual grate zones and the individual grate zones separately adjustable adjusting devices for the supply of primary air and / or for the speed of the fuel in the bed of good individual grate zones are assigned.
- a detector device in the form of several thermographic or infrared cameras, which are those of the good bed temperature corresponding radiation detected individual grate zones and the individual grate zones separately adjustable adjusting devices for the supply of primary air and / or for the speed of the fuel in the bed of good individual grate zones are assigned.
- Known from this document is thus the regulation or control of the individual Rust zones with respect to primary air supply and / or for the Speed as a function of measured grate zone temperatures.
- the invention is based on the object, the fire control in incineration plants, in particular solids incineration plants to optimize so that the emergence of pollutants reduced or prevented within the combustion process is, the combustion conditions in the furnace should be adjusted continuously so that fire-dependent Emissions can be influenced.
- An essential The aim of the fire performance control is in addition to optimal Primary emission reduction measures a maximum, as constant as possible energy conversion.
- the inventive method or the device for Rules of the fire performance of incinerators, in particular Solid fuel incineration plants, where the kiln at the beginning abandoned on a firing grate, on this one schür- and Moving subjected and at the end of the grate the accumulating slag is discharged it is provided that the regulation of the fire performance with regard to a possible Constant maintenance of the produced steam quantity on the one hand and with regard to the lowest possible emission of pollutants on the other hand, and a boiler-friendly as possible or corrosion of the boiler pipes preventive operation in Dependence on at least three measured or measured values derived controlled variables A, B, and C, wherein the Controlled variable A is derived from the measured amount of steam, the controlled variable B at least one type of gas emitted Substances directly or indirectly, and the controlled variable C from at least one of the fuel bed or the firebox assigned Derived temperature and / or calorific value of the fuel is, and the control of the manipulated variables in dependence of at least three measured or derived from measurements Controlled
- the controlled variable B to reproduce the oxygen content of the emitted substances directly or indirectly.
- the measurement of the oxygen content O 2 in the flue gas of the incinerator takes place by means of a gas detector installed at a suitable location preferably in the flue of the incinerator gas detector with which, among other types of gas, the oxygen content O 2 of the flue gas can be measured and processed as a controlled variable. Since the total amount of air is kept constant depending on the load, the average oxygen content of the flue gas is constant with constant heat release and constant fuel composition.
- the method according to the invention is based on the finding that the O 2 signal corresponding to the oxygen content of the flue gas reacts the fastest to a change in the intensity of the fire.
- the oxygen content O 2 in the flue gas is inversely proportional to the live steam mass flow and can thus be used as an early indicator for a changing steam signal.
- the power and oxygen regulators thus affect both the feed and all rust zones. It is important that the oxygen regulator is negatively weighted. This is due to the fact that an O 2 setpoint and actual value behave in opposite directions, ie inversely proportional to each other. If the O 2 content is too low, ie the actual value ⁇ setpoint, this indicates that the steam quantity is too high or increasing. If the regulator were weighted positively, it would make the grate and the charge faster in this case, which would be wrong if the amount of steam was already too high or increasing anyway. For this reason, the O 2 controller is negatively weighted, so if the O 2 value is too low, the rust and feed (if weighted) slows down.
- the controlled variable C is determined from the firing position and / or the firing length of the firing bed, wherein the firing position is derived from one or more measured temperatures at the beginning of the grate or temperatures in the afterburning chamber, and the firing length one or more measured temperatures at the output end of the furnace grate is derived. From experiments it has emerged that the furnace temperatures are also suitable as substitute or additional measured variables for the vapor signal due to their short dead time. In order to obtain a representative value, the mean value can be formed from several temperatures and used for regulation. This average temperature value thus allows as a substitute measured value THu a conclusion on the Brennstoffehrpian Hu.
- the firing position x moves in the direction of slag discharge, as shown in more detail in particular in FIG.
- a pyrometer above the burnout zone indirectly measures the slag temperature. Falling temperatures indicate a shortening of the fire on the grate, rising temperatures on an extension. The correspondingly measured temperature value can thus also be used as a substitute measured variable T I for the fire length I. It is now advantageous in a further development of the invention to be able to influence the firing position x as well as the fire length I by a variation of the transport speeds of the grate. Here, the regulation of the loading and transport speeds can be fully automated.
- the invention also allows a "calorific value" with the manipulated variable y Hu and a “Feuerlagereger” with the manipulated variable y I.
- a particular advantage of the invention is that the fire power control for different types of fuel can be adjusted, with one for each fuel own parameter set intended for the fire power control is, whereby the procedure for the fire power control during the operation of the incinerator to other types of fuel is switchable or can be switched.
- the weighting of the controlled variables takes place in relation to the manipulated variables in the form of weighting factors which are present in their quantity, in particular, according to the weighting matrix shown in FIG.
- these weighting factors have, for example, the following values, each related to a standard value of 10: feed rate transport speed stoking Air volumes u. -distribution Primary air temperature Steam quantity m ⁇ D 9 - 10 9 - 10 0 9 - 10 0 Oxygen O 2 7 - 9 7 - 9 9 - 10 5 - 7 0 Fire position T Hu 0 2 - 4 0 4 - 6 9 - 10 Fire length T I 0 7 - 9 0 3 - 5 0
- a fourth controlled variable D provided, which of the layer thickness and / or the air permeability of the on the grate derived fuel is derived.
- the measurement of Control variable D is preferably carried out by a pressure sensor.
- the in FIG. 1 and 2 schematically illustrated incinerator includes a furnace grate 1, a charging device 2, a combustion chamber 3 with subsequent throttle cable 4, to the further throttle cables and the incinerator downstream Aggregates, in particular steam generation and emission control systems connect, which is not shown here and are explained.
- the grate 1 comprises individually driven grate stages 5. Said drive makes it possible to adjust both the transport or conveying speed and the quenching speed.
- the firing grate has, in addition to the transport of the fuel 16 and the function to stoke the kiln. Below the firing grate divided subwind chambers 7.1 to 7.5 are provided both in the longitudinal direction and in the transverse direction, which are acted upon separately via individual lines 8.1 to 8.5 with primary air L ⁇ P. At the end of the firing grate 1, the burned slag is discharged into a slag chute 10, from where the slag falls into a non-slag chaff.
- the loading device 2 comprises a feed hopper 11, a task chute 12, a feed table 13 and one or several adjacent and / or superimposed, if necessary independently controllable feed pistons 14, the slipping down in the task chute 12 garbage via a feed edge 15 of the feed table 13 in the furnace 3 on the grate 1 slide.
- the hopper 11 Over the charge becomes fuel from the lower mouth the hopper 11 evenly over the entire Grate width abandoned.
- it is a plant with a discontinuous Feeding with a four-part dosing tappet (top left, top right, bottom left, bottom right).
- a slow forward stroke and a fast return stroke the Feuerungsrost 1 quasi continuously fed.
- the applied to the furnace grate 1 fuel 16 is pre-dried by coming from the underwinding 7.1 air and heated by the radiation prevailing in the furnace 3 radiation and ignited.
- the underwind zones 7.2 and 7.3 In the area of the underwind zones 7.2 and 7.3 is the main fire zone, while in the area of the underwind zones 7.4 and 7.5 the forming slag burns out and then into the slag chute 10 passes.
- various actuators are shown in FIG. 1 and 2 indicated that serve to control various factors or devices to perform the desired control of the fire performance can.
- the adjusting devices for influencing the transport and speeding speeds wsn with 21, for the on and off frequency or for the speeds w B of the feed piston with 23, and designated for the primary air quantities L Pn with 24, which is able to each individual sub-wind chamber 7 to supply the required primary air quantities L ⁇ Pn .
- the first approximation the free air outlet surface through the grate surface and the fuel bed is equivalent, are in each air supply line 8 an air flow meter 18 and in the underwinding chambers 7.1 and 7.2, a temperature sensor 17 and in the Underwinding 7.1 a pressure sensor 19 is provided while in Firebox 3 two more temperature sensors 20a and 20b arranged are the temperatures at two different To be able to measure places in the firebox 3.
- a goal of an optimal fire guidance is, the emergence of pollutants within the combustion process or to prevent. These are the combustion conditions continuously adjusted in the firebox so that it is fire-dependent Emissions can be influenced. These measures are of particular importance as they the pollutants do not shift, but their formation actually reduce or prevent. It is about Here, therefore, to dynamic measures, the control technology in to intervene in the combustion process. These measures will be summarized under the term combustion control. Of the according to historically coined term is so far misleading, because with the fire performance control actually not only the fire performance, ie the steam production, regulated but in parallel and even superficially combustion-dependent pollutants are minimized. Another one essential goal of the so-called fire power control is in addition to optimal primary measures for emission reduction also a maximum, as constant as possible energy conversion. The Usually prevailing rule philosophy consists here in a fixation on a guaranteed nominal steam generation, i. on "dash" drive the incinerator under any time Compliance with the setpoint.
- a gas detector 25 is installed at a suitable location in the throttle cable 4, with which, inter alia, the oxygen content O 2 of the flue gas can be measured and processed further as a controlled variable.
- the average oxygen content of the flue gas is constant with constant heat release and constant fuel composition.
- O 2 signal reacts the fastest to a change in the fire intensity.
- the oxygen content O 2 in the flue gas is inversely proportional to the live steam mass flow and can thus be used as an early indicator for a changing steam signal.
- the power and oxygen regulators thus affect both the feed and all rust zones. It is important that the oxygen regulator is negatively weighted. This is due to the fact that a 02-Soll- u. Actual value in opposite directions - ie inversely proportional to each other. Too low an O 2 content, ie actual value ⁇ set value, indicates an excessive or increasing steam quantity. If the regulator were weighted positively, it would make the grate and the charge faster in this case, which would be wrong if the amount of steam was already too high or increasing anyway. For this reason, the O 2 controller is negatively weighted, so if the O 2 value is too low, the rust and feed (if weighted) slows down.
- the combustion chamber temperature is in Area of the afterburning chamber, and with the temperature sensor 20b the combustion chamber temperature in the area of the end of the rust in the Ausbranddecke measured.
- the two temperature sensors 20a and 20b are, for example, radiation pyrometers ("cameras"), which at suitable places in the afterburning chamber or in the Ausbranddecke are installed at the end of the grate.
- the two radiation pyrometers 20a and 20b are intended to provide inferences on the calorific value of the current fuel increase and, where appropriate, to respond and appropriate Initiate countermeasures.
- furnace temperatures are also suitable as substitute or additional measured variables for the vapor signal due to their short dead time.
- the mean value of both temperatures is formed and used for regulation. This average temperature value thus allows as a substitute measured variable T Hu a conclusion on the Brennstoffikiwert H u .
- the camera 20b supplies a signal, which can thus also be used as a substitute measured variable TI for the fire length I. It now makes sense to be able to influence the firing position x and the firing length I by varying the transport speeds of the grate. Here, the regulation of the loading and transport speeds can be fully automated.
- the invention also allows a "calorific value" with the manipulated variable Y Hu and a “Feuerlagereger” with the manipulated variable Y I.
- FIG. 4 shows a schematic weighting matrix of the control scheme in dependence the controlled and controlled variables of the incinerator with weighting factors
- FIG. 5 and 6 schematically the Control processes, wherein in FIG. 5 the load-dependent air volumes and the primary air distribution and the controlled air volume distribution, and in FIG. 6 the load-dependent transport speeds, as well as correction and adjustment of the transport speeds are considered.
- each PID controller On the input side, each PID controller has a connection w for the corresponding respective input variable as setpoint and one Connection x for the corresponding actual value of the controlled variable, and supplies at the output in each case a manipulated variable value y to the Evaluation and control circuit 27.
- This provides under consideration of correction factors K and especially considering the predetermined weighting factors according to the invention G the corresponding control signals for control the amounts of air L ⁇ (Fig. 5) and the loading, purging and transport speeds w ⁇ (Fig. 6).
- the Fig.4 is a matrix with zone and controller dependent Single weighting factors for the fixed load (GF), the oxygen content (GO2), the calorific value (GHu) and the firing length (GI) clarify, with a "big” symbol a weighting factor of 100% means; is in an intersection of the manipulated variable and control variable no symbol, this sets one Weighting factor of 0%; So, the bigger it is Symbol, the greater the weighting factor.
- GF fixed load
- GO2 oxygen content
- GHu calorific value
- GI firing length
- any number other than 0% weights the influence accordingly for the respective zone in the range of -100% to +100% .
- the air volumes and their distribution and the Transport speeds are thus from all four controllers while the stinging speed only is changed over the oxygen content.
- the loading speed is primarily controlled by the amount of steam regulated, secondary to the oxygen content in the flue gas.
- FIG. 4 shows that the calorific value and fire length controller for the feed are weighted at 0% - so these two controllers have no effect on the feed rate control. Nor do they have any influence on a change in the quenching speed.
- a change in the primary air temperature can only cause the calorific value, which makes sense, because the relationship between T Hu and fire position could be proved.
- the context applies that by means of an increased primary air temperature T PL a lower calorific value and thus a lower T Hu can be counteracted.
- a fourth controlled variable D provided, which of the layer thickness and / or the air permeability of the on the grate derived combustion material is derived (Fig. 2/16).
- the measurement of the controlled variable D is preferably carried out by a in Fig. 2 illustrated pressure sensor 19.
- the measurement of the controlled variable However, D by the pressure sensor 19 can also in each any zone 1-x or in each zone 1-x.
- D by the pressure sensor 19 can also in each any zone 1-x or in each zone 1-x.
