Definitions

  • the invention relates to a method for controlling the power of steam generators for power generation and / or heat supply, preferably to such steam generators, which include boilers fired with fossil or organic fuels, taking into account the use of steam and / or water-operated cleaning facilities for the Heating surfaces of the steam generator during its operation.
  • the method for controlling the capacity of steam generators according to the present invention also includes the power control of steam generators with combustion plants for the combustion of residues, co-incineration of residues and for the incineration of refuse.
  • the method for regulating the capacity of steam generators according to the invention comprises, in particular, the power control on such steam generators, which are frequently operated in the area of maximum power.
  • the nominal rated power is the highest continuous electrical power (or, in the case of heat generators, the heat output) of the steam generator under rated conditions (see VGB Guideline RV 809).
  • the rated capacity of a steam generator is statically determined and corresponds to the design value of the steam generator. This differs from the bottleneck performance, which is also stated as continuous performance under normal conditions and is limited by the weakest part of the investment (bottleneck) over longer periods (see VGB Guideline RV 809).
  • the terms "rated power” and “bottleneck power” are used interchangeably to denote a nominally limited electrical power.
  • steam-powered and / or water-operated cleaning devices are to be understood as meaning, in particular, steam blowers or steam lance screw blowers, eco steam blowers, water / steam guns, water lance blowers and water blowers.
  • steam blowers or steam lance screw blowers are to be understood as meaning, in particular, steam blowers or steam lance screw blowers, eco steam blowers, water / steam guns, water lance blowers and water blowers.
  • the radiant heating surfaces of the combustion chamber of a steam boiler are cleaned during operation with water lance blowers, with steam blowers and similar equipment, the Nachschaltsammlung lake are cleaned.
  • a targeted and suitable cleaning during operation of the steam generator is therefore essential.
  • the polluted area in the boiler should be cleaned as accurately as possible and as needed, as both an insufficient cleaning deteriorates the condition of the system, as well as excessive cleaning. Excessive cleaning is associated with increased wear of the equipment concerned, which is also undesirable.
  • a method for controlling a water lance blower which in particular takes into account the wear problem is, for example, from DE 10 2006 022 627 A1 known.
  • DE 10 2006 022 627 A1 describes a cleaning method in which only a surface and circumferentially limited slagging area of the steam generator is cleaned.
  • a similar method is for example from DE 281453 B5 known.
  • Another method for controlling the operation of a water lance for cleaning a Feuerungswand is for example from the DE 41 39 838 A1 known.
  • a method for power control of steam generators taking into account the use of steam and / or water-operated cleaning devices is for example from US 2006/0178762 A1 known.
  • a method for regulating the capacity of steam generators using steam and / or water-operated cleaning devices is also known, for example, from US Pat US 2009/0090311 A1 known. Control of the purifiers is done using a predictive model for maximum efficiency of the steam generator.
  • the invention is therefore based on the object to provide a method for power control of steam generators, which ensures both optimum performance and optimal efficiency of the steam generator, taking into account the use of steam and / or water-operated cleaning devices during operation of the boiler or the steam generator.
  • An additional aspect of the invention relates to a comprehensive power control of several power generation plants with optimal consideration of the requirements for the short-term provision of control energy.
  • a steam generator in the context of the present application is a power plant block with a firing device and an associated water-steam cycle to understand.
  • Several steam generators or power plant blocks can be combined to form a power plant.
  • boiler used in the present application is used synonymously for the term “steam generator”.
  • An effectiveness prognosis in the sense of the present application is understood to mean a prognosis such that a cleaning time and / or cleaning cycle is defined which, under predominantly technical aspects of effectiveness of the heating surfaces, is suitable for preventing excessive material wear and / or unscheduled plant downtime.
  • an effectiveness prognosis can be based on changing measured values of the temperature of the heating surfaces associated with a contamination.
  • a change in the desired cleaning process represents, in particular, a displacement or suppression and / or shortening or lengthening and / or intensification or weakening of the cleaning process.
  • the desired cleaning process is changed insofar as the intervention in the steam generator is changed at the originally planned time to optimally adjust the actual output of the steam generator in terms of load forecasting.
  • a load forecast is to be understood as a forecast of a presumed demand (load) for the steam generator for the provision of electricity / heat.
  • the load prognosis can be created, for example, by a network operator, a redistributor, an energy trader or in the controller of the steam generator itself.
  • the load prognosis preferably takes into account whether and with what output the steam generator, taking into account the merit order, is used to cover the load.
  • Load forecasting and availability forecasting are preferably adapted to each other within the scope of several iterations.
  • an availability forecast is to be understood as meaning a forecast of a maximum available power of the steam generator which may be below or above the rated power or bottleneck power of the steam generator or the relevant power plant unit, depending on the conditions. This is based on the finding that the actual available power of a steam generator fluctuates around the rated output of the steam generator. Among other factors, in particular, the ambient temperature and the quality of the fuel have a great influence on the actual available power. Above all, the ambient temperature has an influence on the cooling capacity of the cooling towers, which possibly represents a limiting factor for the utilizable output of a steam generator. At relatively low daytime temperatures, the performance is greater than at high ambient temperatures.
  • the power is also dependent on the calorific value of the fuel used, for example, when using coal as a fuel, the performance depends on the coal quality used.
  • a change in the quality of coal for example, cause a change in the amount of flue gas, which in turn is accompanied by a change in the power requirement of the fan and thus has an influence on the (net) performance of the steam generator.
  • a load prognosis is additionally consulted as a function of the power requirement and / or heat requirement as a criterion for determining a cleaning time and cleaning cycle, in such a way that an optimum cleaning time determined from the point of view of effectiveness in terms of a technical availability of the steam generator and / or, if appropriate, an optimum cleaning time determined in the sense of a proportion of the surfaces to be cleaned is shifted in a load-dependent manner.
  • the intensity of the cleaning process can be increased or decreased. This is based on the consideration that at peak demand in the network maximum possible power output of the boiler is desirable, so that in these windows a cleaning-related load drop of the boiler should be avoided.
  • the time windows available for a cleaning and / or a cleaning cycle can be shifted or optimized according to the invention in the sense of full load optimization depending on the power requirement.
  • an optimum cleaning time if it falls in a phase of peak demand, may possibly be shifted so that it falls into a phase of lower load requirements of the steam generator, in the course of the then also the electricity price, which depends on the demand, is lower.
  • the demand-based cleaning and the resulting reduced power of the steam generator is coupled to the current power requirement and the resulting electricity price or to the current heat demand.
  • the method described above is particularly suitable for use with lignite-fired boilers or steam generators, since Lignite contains, depending on the nature of high levels of slag-forming substances and in such steam generators efficiency-optimized operation is particularly important.
  • At least the heating surface temperatures and / or the live steam temperature of the steam generator and / or the reheater temperatures of the steam generator are detected and / or measured as state variables of the steam generator.
  • the heating surface temperatures can be used, for example, to determine the state of soiling of the heating surfaces; these can be determined, for example, by means of the known thermal imaging methods.
  • the wall temperature of the firebox can serve as an indicator of the fouling state of the firebox.
  • the temperature of the heating surfaces can be measured, for example, with suitable temperature sensors.
  • the load forecast for the steam generator is created as a function of meteorological forecast data. It is generally known that in certain weather conditions less power from renewable energy sources is fed into the grid, so that it is possible to create a reliable load forecast over a period of several days. In the case of the provision of heat by the steam generator, the load forecast is based on a forecasted heat demand. A load prognosis does not necessarily have to be made on the basis of meteorological forecasts; for example, the load prognosis may also be based on the planned connection or disconnection of industrial electricity and / or heat consumers. For example, when starting up a production plant for the production of aluminum, considerable amounts of electricity are required, so that the startup of such a system represents a predictable load case.
  • a target cleaning process can be suppressed and / or mitigated and / or shifted and / or shortened, with predicted low load, a target cleaning process can be brought forward and / or intensified.
  • a cleaning process is to be understood, which is useful and desirable due to the effectiveness of prognosis at a certain time of cleaning, but which is not mandatory at this time.
  • Such a mandatory cleaning process to a mandatory mandatory cleaning time is only such a cleaning process that is triggered when falling below a predetermined minimum effectiveness of the heating surface or when exceeding a maximum allowable contamination of the heating surface.
  • a certain cleaning cycle is passed through, which may optionally also be provided not to postpone the cleaning time, but to limit or extend the scope of cleaning in terms of surfaces to be cleaned.
  • the cleaning intensity can be reduced or increased, for example, by controlling the water pressure when using water lances blowers.
  • the term of cleaning in the sense of the present application is the beginning of a cleaning cycle.
  • a target cleaning process which is suppressed in a high-load phase of the power supply and is taken up at a later time, is then intensified in order to avoid permanent soiling on the heating surfaces.
  • An expected cleaning-related wear of the heating surfaces as a function of the duration and the scale extent of a cleaning process can also be used as input to the fuzzy controller.
  • the load forecast is preferably displayed as electricity price forecast.
  • the electricity price forecast is then used as the input variable in the fuzzy controller.
  • diagnostic systems such as heating surface effectivity oriented Rußblas management systems or, for example, infrared camera-guided cleaning systems
  • the technical cleaning needs and the technically optimized cleaning time is determined and passed on to the control system for controlling the cleaning equipment.
  • the technical cleaning requirement is the need for cleaning resulting from the effectiveness prognosis, as already explained above.
  • the load forecast can be created as a heat demand forecast, for example, seasonally or depending on the connection and disconnection of industrial customers.
  • load, cleaning and use planning in a steam generator are assessed and automated by a load controller.
  • a load controller for example, a device for electronic data processing can be provided with appropriate software.
  • the time and technical scope for action is determined and, for example, coupled with the price development and the demand on the electricity market. This then results in a price-optimized and demand-optimized cleaning plan, which then, at times with high prices in the electricity market, as possible no minimum loads allowed and controls the cleaning facilities in low price phases. This will change the current current and Heat requirement optimally taken into account. Fuel optimization can also be included in this optimization.
  • the proceeds / prices resulting from the electricity market or heat demand are estimated, the reasonable cleaning cycles are determined and an optimum of both criteria is sought and controlled.
  • the control of the cleaning systems can then be done automatically by the diagnostic systems and / or control technology, or forwarded as a recommendation to the operating team, which then performs the control.
  • a desired cleaning process is shifted into a period of forecasted high availability.
  • the higher maximum possible output of the steam generator is taken into account. This is particularly advantageous if the higher maximum possible power is not already included in the availability forecast, but only at short notice due to changed parameters that are otherwise performance limiting.
  • performance-limiting factors of the steam generator are monitored and taken into account in the preparation of the availability forecast and in the current control. These are, for example, the calorific value of the fuel, the live steam quantity, live steam temperature, reheater temperature, reheater pressure, reheater amount and / or cooling water temperature.
  • the control of the power of the steam generator is possible in a conventional manner via frequency control and secondary power control behind a generator.
  • the power control takes place via the control of electrical power, which is discharged from a steam generator downstream generator in a power grid.
  • the load forecast, availability forecast, and effectiveness forecast are made for periods of hours and days, preferably for periods between about 0 to 24 hours for the current day and between about 0 to 48 hours for the following days.
  • control plan can be submitted as a schedule for the mode of operation of the steam generator in the form of a daily schedule for a subsequent day at which then the control of the steam generator based on the control plan, the control plan sets the reference variables for the performance of the steam generator.
  • the availability forecast includes supplementary performance options and / or options for the provision of control energy.
  • Supplementary performance options are, in particular, those which in any case at times enable a higher output of the steam generator, but may be associated with a lower efficiency of the steam generator.
  • An example of such a supplemental performance option is the shutdown of preheaters. This achieves an increase in power at the expense of efficiency.
  • the power bands of the steam generator can be specified in more detail, in which the control power can be provided.
  • the method according to the invention makes it possible to use the full load potential of a steam generator in the sense that it is also possible to dispose of a maximum power lying above the nominal power / bottleneck capacity of the steam generator.
  • the better predictability of performance allows for a narrower band of security in the performance offered.
  • availability prediction it would be necessary to provide some power bandwidth around the rated power of the steam generator as unavailable block power, and to control the steam generator according to the load requirements of the power grid, where appropriate, within that range.
  • By creating an availability forecast it is possible to have the steam generator's output above the rated output of the steam generator, so that when planning a cleaning operation, the maximum possible output of the steam generator can be taken into account.
  • Another advantage of the invention with simultaneous consideration of several steam generators and / or at least one steam generator and a system for the provision of control energy in the context of a balancing group management.
  • steam generators that they have to keep a fixed part of their power as a reserve (control energy) ready to comply exactly with the load demand and / or to contribute to grid stability, if necessary.
  • This requirement can also be fulfilled by providing a corresponding service in the context of balancing group management.
  • a method for power control of steam generators for power generation and / or heat supply in which at least one steam generator and a system for the provision of control energy are combined to form a virtual balancing group.
  • the plant for the provision of control energy can be any type of energy producer that is able to provide on request a sufficient, previously defined power within a given period of time. Decisive for the suitability are therefore above all the maximum power as well as the possible starting ramp for achieving the maximum power.

  • This method has the advantage that the steam generators can be driven in contrast to previously with their maximum power and do not have to provide control energy. This allows a more economical use of the steam generator, in particular also, from the point of view of system wear, since frequent load changes can be avoided.
