Definitions

  • the invention relates to a waste-throughput limiting control for a fire power control of a waste incineration plant according to claim 1 and a method for operating a waste-throughput limiting control according to claim 11.
  • Waste incineration plants can use a heat output from waste incineration to convert it into electrical energy.
  • the heat of combustion is coupled via heat exchangers with steam generators in steam boilers.
  • the generated steam is directed via a steam distributor to a steam turbine where it serves its drive.
  • As a measure of the steam power produced is generally a steam mass flow in [kg / s] indicated.
  • a method for operating a waste incineration plant is, for example, from EP-B-0499976 known.
  • the garbage supply and the primary air supply by means of a uniform generation of heat quantity influenced in the same direction cascade control.
  • the generated amount of steam is detected and serves as the main controlled variable. Strong changes in the quality of the waste and thus the calorific value, which require a change in the operating parameters in the opposite sense, are adequately compensated by this fire performance control accordingly.
  • the manipulated variables waste throughput and air supply to the combustion chamber are influenced.
  • the regulation is carried out in such a way that the waste throughput or the air supply is reduced by a protective element when a predetermined maximum value is exceeded by at least one of the controlled variables.
  • the indirectly recorded waste throughput is a quasi-current instantaneous value.
  • the quasi-current instantaneous value In terms of the whole Dwell time of the waste in the supply and transport through the combustion chamber, which is in the order of 2 h, requires the indirect detection of the quasi-current instantaneous value a strong time-delayed reaction possibility with respect to the loading of the feed system.
  • Object of the present invention is therefore to provide a control unit for a fire power control of a waste incineration plant, which detects the actual waste throughput and thus the feed state and an ongoing, not operationally undesirable overload operation of the waste incineration plant is avoided.
  • the object is achieved by a waste throughput limiting control for a downstream combustion control of a waste incineration plant according to claim 1 and a method for operating a waste flow limiting control according to claim 11.
  • the inventive waste throughput limiting control has an averaging unit, a waste throughput limiting controller and a minimum unit. Starting from at least two input signals, a waste weight applied to a feed system of the waste incineration plant and a predetermined maximum waste throughput, the waste flow limiting control generates an output signal for a steam output setpoint for further processing in a downstream firing power control.
  • the steam power setpoint is adjusted in such a way that at a determined depending on the weight of the garbage averaged waste throughput, which is greater than one of Maximum waste throughput dependent limit value, the Dartpf sossollwert is substantially reduced. As a result, the downstream combustion control will reduce waste throughput.
  • a firing diagram 10 like the one in Fig. 1 shown, forms the basis for the design of a waste incineration plant.
  • the heat output PW generated in the combustion process is represented in the firing diagram 10 as a function of the waste throughput MD.
  • straight lines of calorific values H0, H1, H2 of different waste qualities continue to be entered therein.
  • a hexagonal area surrounds a work area 12 specified for the waste incineration plant, which includes all steady state conditions guaranteed by the manufacturer.
  • the working area 12 is limited by straight lines of a low calorific value H0 and a high calorific value H2, a minimum heat output 14 and maximum heat output 16 and a minimum waste throughput 18 and a maximum waste throughput 20.
  • the heat output PW and the waste throughput MD of a desired operating point in the work area 12 fluctuate due to an inhomogeneous waste quality and due to a discontinuous loading of a feed system.
  • these fluctuations can lead to overload conditions.
  • Short-term overload conditions in the range of minutes usually do not lead to damage for the waste incineration plant.
  • prolonged overload conditions are to be avoided in order to avoid after-effects, such as to avoid material fatigue, damming in the feeding system, unstable fire situation or exceeding of legal regulations.
  • the waste throughput limiting control MBR occurs in the sense of a cascade control as a master controller for the reference variable steam setpoint DS of a downstream fire power control FLR, for example according to the EP-B-0499976 , on.
  • Fig. 2 is shown a block diagram of a waste flow limiting control MBR.
  • the material entry that is the loading of waste, takes place with the aid of a gripper 24 of a crane system.
  • the waste is discharged into a hopper, not shown, a hopper and loaded in this way, also not shown dispensing system.
  • a pick-up weight MG picked up by the gripper 24 is determined and transmitted via an electrical signal line to the waste-throughput limiting control MBR.
  • the detection of the garbage weights MG allows a detailed knowledge and analysis of the momentary state of the loading system (loading condition) and allows a targeted intervention to adapt the loading condition with changing garbage composition.
  • this Knowledge of the feed state and including a current steam power value extrapolation of future positions of the operating point and thus future operating conditions possible.
  • the waste throughput limiting control MBR is in Fig. 2 is delimited by a dashed line and in this preferred embodiment comprises the following units: an averaging unit ME, a garbage rate limiting controller MBr and a minimum unit MIN.
  • the units ME, MBr, MIN are hardware and / or software implemented in this embodiment by means of electronic components. Alternatively, however, the units ME, MBr, MIN can also be realized by means of pneumatic components.
  • the averaging unit ME receives as input signal the garbage weights MG of each filled into the hopper garbage.
  • the averaging unit ME determines therefrom over averaging period of 1 h to 5 h, preferably 3.5 h, a moving average of the garbage weights MG, divides this moving average by the averaging period and thereby generates an average garbage throughput gMD.
  • the garbage weights MG with the in Fig. 3 dashed line folding function 26 weighted.
  • exemplary garbage weights MG are shown as a function of time t in the form of discretely applied bars.
  • the averaging period ranges from -3.5 h to 0 h, which is 3.5 h.
  • plotted convolution function 26 has a continuous rising from the time 0 h, leading edge in time 28 and a steady from the time - 3 h falling, trailing edge 30 on. Between the leading and trailing edge 28, 30, the folding function 26 is at least almost constant.
  • the averaging period can, of course, be adjusted to specific requirements. Thus, in practice, for example, it proves useful to form a further moving average value over 8 hours, which can be included in the control or is made available to a user as additional information.
  • the convolution function 26 can also be adapted to specific circumstances.
  • the averaging unit ME described above is equivalent to a low-pass filter and can be physically replaced by such a low-pass filter.
  • various parameters can also be adapted to the specific circumstances in the case of a low-pass filter.
  • the average garbage throughput gMD represents a smoothing of the garbage weights MG discretely filled into the hopper.
  • a so-called deadband TB is supplied in addition to the averaged waste throughput gMD.
  • the waste-throughput limiting controller MBr determines a regulated steam power setpoint value DSr. A detailed description of the structure and function of the waste throughput limiting controller MBr is given in connection with FIG Fig. 4 ,
  • the minimum unit MIN following the signal flow to the waste-throughput limiting controller MBr receives, in addition to the regulated steam power setpoint DSr, a steam power setpoint DSh determined manually by the operator and a calculated steam power setpoint DSb.
  • the calculated steam power setpoint value DSb is determined in a steam power calculation unit DLB from at least one calorific value HWh to be entered by the operator on the basis of model calculations.
  • the minimum unit MIN determines the smallest of the three input signals DSr, DSh, DSb and forwards this output signal of the waste-throughput limiting control MBR as a steam power setpoint DS to the downstream fire power control FLR.
  • the fire power control FLR then generates corresponding control values, which influences the loading of the charging system via the gripper 24.
  • Fig. 4 a detailed block diagram of the waste throughput limiting controller MBr is shown.
  • the waste flow limiting controller MBr has three more, not shown in the overview input signals: a maximum waste throughput MDmax, a scaling factor SF and an on / off switching signal I / O.
  • a differential waste throughput DMD is first determined from the difference between the averaged waste throughput gMD and the maximum waste throughput MDmax in a differential element DG.
  • the differential waste throughput DMD is used together with the deadband TB, as an input signal Deadband adapter TBA supplied.
  • the function of the dead band adapter TBA will now be related to Fig. 5 explained.
  • the diagram in Fig. 5 shows an output signal tDMD of the dead band adapter TBA as a function of the differential waste throughput DMD.
  • the output signal tDMD DMD-TB is lowered by the amount of the deadband TB.
  • a dash-dotted line 32 in the diagram in FIG Fig. 5 along the Function tDMD DMD entered. If the average garbage throughput gMD and thus also the differential garbage throughput DMD decreases again, then the output signal tDMD goes through the stepped and in Fig. 5 consistently thick registered line of the transfer function 34 of the deadband adapter TBA in the reverse direction.
  • the output value tDMD is fed to the PI controller PI-R of known structure and function.
  • a proportional coefficient and a reset time can be set as parameters of the PI controller PI-R, but in Fig. 4 not listed separately as input signals.
  • the input signal tDMD is treated by the PI controller PI-R as a control deviation that is minimized according to the selected parameters.
  • the PI controller increases an output signal ds at a negative control deviation, that is, as long as the average waste throughput gMD is less than the maximum waste throughput MDmax, and reduces the output signal as soon as the control deviation has a positive sign, so the average waste throughput gMD minus the deadband TB exceeds the maximum waste throughput MDmax.
  • the output signal ds of the PI controller PI-R is through Multiplication with the scaling factor SF at a multiplier P in the regulated steam setpoint DSr converted and fed to the subsequent minimum unit MIN.
  • the further input signal I / O makes it possible to switch on or off the automatic operation of the waste-throughput limiting control MBR with the waste-throughput limiting controller MBr.
  • the method for operating the waste throughput limiting control MBR described above comprises at least the step that, starting from at least two input signals, namely the refuse weight MG and the predetermined maximum refuse throughput MDmax, an output signal Dampf amongssollwert DS for further processing in the Feuer insregelung FLR is generated such that at depending on Mine weight MG determined average garbage throughput gMD, which is greater than a maximum dependent on the maximum waste throughput MDmax limit, the steam power setpoint DS is reduced in order to prevent a continuous overload operation of the incinerator.
  • the method preferably includes a further input signal, namely a deadband TB, such that it is greater than the maximum waste throughput MDmax and less than or equal to the limit value resulting from the sum of the maximum values at an average waste throughput gMD Garbage throughput MDmax and the deadband TB results, the steam power setpoint DS (with unchanged manually set and calculated steam power setpoint DSh, DSb) remains constant.
  • the averaged garbage throughput gMD is determined in a previous process step as a moving time average from the garbage weights MG in the averaging unit ME.
