Description

DESCRIPTION FOR STEAM DEVICES FOR ELECTRICITY GENERATION AND/OR HEAT PROVISION METHOD FOR POWER ADJUSTMENT The invention suggests that vaporizers, preferably fossils or organic steam appliances containing fuel-fired boilers, i.e. steam for the heating surfaces of the steam appliance during its operation. and/or taking into account water-driven cleaning schemes power regulation for electricity generation and/or heat supply relates to a method.

For power regulation of steam appliances, according to the present invention the method is to burn the waste materials, to combine the waste materials have ignition facilities for incineration and incineration of garbage It also covers the power adjustment of steam devices.

Method according to the invention for power regulation of steam appliances In particular, this type, which is often operated in the maximum power field, It covers power adjustment of steam appliances.

As the rated power, the steam appliance is the lowest under the rated conditions. high electrical continuous power (or heat generators power) is indicated (compare VGB directive RV 809). A the rated power of the steamer is statically fixed and corresponds to the design value of the steam appliance. Same here supplied as continuous power under rated conditions and of the plant part with the lowest power (bottleneck) limited for longer periods of time The bottleneck gas capacity differs. (compare VGB directive RV 809). Below, “nominal power” and “bottleneck” “capacity” concepts are a nominally limited synonymously as the marking of electric power will be used.

Cleaning with steam and/or water, in the sense of the present application especially steam blowers or steam spiral bellows, eco steam blowers, water/steam cannons, water pipe bellows and water bellows are to be understood. accustomed to with water pipe bellows, during processing a steam radiant heating surfaces of the boiler fire area and steam the secondary of a steam boiler with blowers and similar devices Heating surfaces are cleaned.

For fossil fuels for electricity generation and heat use Ignition plants, co-incineration for residual materials facilities and incineration plants, ash in fuels exposed to an increased boiler pollution due to remains. This pollution is therefore in working condition water and/or should be cleaned with steam-operated cleaning devices.

The steam required for cleaning is usually processed from the premises. separated as steam. In time for cleaning if it does not occur and is noticeably late, meltdowns, sintering of precipitates or chemical processes depressions to be based on heat transfer and the impact of the facilities persistent persistent causes crusting. According to the type and extent of the collapses, the planned a mechanical/hydraulic cleaning during a downtime should be carried out. In this way, partly significant costs and resulting in usability losses. In addition, larger an involuntary ejection of light cooking e.g. secondary heating mechanical damage to boilers on their surfaces may cause.

Therefore, during the operation of the steam device targeted. and Proper cleaning is inevitable. Here in the cauldron the polluted area is as appropriate to the target and need as possible. must be cleaned in some way, because both insufficient cleaning and An excessive cleaning worsens the condition of the facility. an extreme cleaning, with increased wear of the relevant plant parts emerge together.

The steam required for the cleaning devices to work is not available for electricity generation, so no such steam output should be considered equal to power losses.

For cleaning boiler walls or radiant heating surfaces The use of water intended for cooling cools the boiler walls and normally serving electricity generation or heat use takes its heat, so this cleaning process is usually a power associated with the loss.

Boundaries of contaminated areas against uncontaminated areas with a certain vagueness, the exact determination of generally larger area due to exposure should be cleaned. Here, clean surfaces are also exposed to steam or water. is left so that these areas are disproportionately cooled and impairs steam production. clean heating surfaces cleaning is susceptible to abrasion and should be avoided as much as possible. should be avoided.

As a result, the use of water and steam is usually fresh steam and leads to a decrease in reheater temperatures, resulting in a power drop and has the consequences of loss of effectiveness.

For checking a water pipe bellows, especially for wear A method that also takes into account the problems of eg DE 10 2006 022 It is known from the patent number 627 A1. fire field of the wall areas to be cleaned by cleaning the walls DE 10 due to the fact that it occurs with a certain thermal stress a superficial or peripherally limited dross A cleaning process is described in which the area is cleaned. Similar a method, for example from DE 281453 B5 known. For cleaning an ignition wall Another method of controlling the functioning of the water pipe known, for example, from DE 41 39 838 A1.

Known methods for controlling cleaning devices overriding target, with greater usability losses win without a connected facility stoppage to ensure its existence as long as possible.

The increasing growth generated by renewable energy sources an increasing focus on energy supply and electricity market requirement fluctuation occurs, so it is usually steam, which serves to supply the base load in the electricity market all the load of the related steam device as much as possible. desire to operate in such a way that their potential is available Use of steam and/or water powered cleaning devices for power regulation of steam appliances, taking into account known.

Cleaning of steam appliances with steam and/or water A method for power regulation by the use of control of the devices, a maximum power efficiency of the steamer This is accomplished by the use of a forecasting model for

Therefore, the underlying purpose of the invention is to make steam devices, use of steam and/or water powered cleaning devices operation of the boiler or steam appliance, taking into account the steam appliance both an optimum power efficiency and a method of power adjustment that ensures optimum efficiency is to present.

A further aspect of the invention is that the control energy is short-lived. optimum consideration of the demands for The hanging power of many facilities for electricity generation relates to the setting.

An ignition with a steam appliance in the sense of the present application a water-steam cycle with a water-steam cycle power plant blog should be understood. Many steamers or power plant blocks combined for one power plant The term boiler used in the present application is the term "steam appliance" used synonymously for

A method according to claim 1, which is the object of the invention. can be reached with Advantageous embodiments of the method emerges from claims.

Cleaning of steam appliances with steam and/or water the use of the devices during the operation of the steam appliance power for electricity generation and/or heat supply, taking into account method for setting. the following process steps covers: - the effectiveness of the steamer, the heater surfaces of the steamer and/or directly or indirectly on the degree of pollution. monitoring system parameters that confirm the results, - via measured and/or determined system parameters generating an efficiency estimate, - a market's current and/or job demand generating a load estimate as a function of - the maximum possible power of the steam appliance available the availability estimate of an estimate and the expected as a function of environmental temperature and/or fuel quality creation, - in the sense of a technical usability of the steam appliance as an estimation of the optimum cleaning instant determination; here for load estimation and availability after the event estimation based on the forecast rated cleaning process steam appliance to be started the pre-given minimum effectiveness of the heater surfaces. not to lag behind and/or pre-warming the heater surfaces. condition that the maximum permissible contamination given is not exceeded is replaced with.

An estimate in the sense of the current application under the name of the event estimate major material wear and/or other than planning mainly technical to avoid a plant standstill a cleaning that is suitable for heating surfaces from all points of view. determination of the spike and/or the cleaning cycle should be understood. Here is an efficiency estimate, for example the heater Measurement of the variable temperature occurring with a pollution of surfaces it depends on their values.

A variation of the nominal cleaning operation In particular, its postponement or elimination and/or shortening or lengthening and/or intensifying or mitigating represents. In other words, the nominal cleaning process of the steam appliance to optimally adapt its noble power in terms of forecasting to the point of intervening in the steam appliance at the pre-planned moment until changed.

In terms of current invention, electricity and heat are called load estimation. on a possible inquiry (load) to the steamer to ensure an estimate must be understood. Load forecasting for example a network by the carrier, a distributor, an energy seller or can be created under the control of the steam device. Load forecast here preferably with which force of the steam device, merit order should be taken into account. It takes into account that it is used for covering the load.

Load estimation and availability estimation preferably many are adapted to each other in the framework of iteration.

Under the name of usability estimation in terms of current invention The maximal force possibly present of the steamer an estimate on it must be understood; here this is the maximum force, the steam appliance or the associated power plant, according to the circumstances. below the rated force of the block or the bottleneck capacity or above. The underlying understanding is a steam the nominal power of the steam appliance actually found its value fluctuates around it. Among other factors actual force, especially at ambient temperature and fuel quality has a great influence on Environmental temperature is here In particular, a steam appliance may be used if necessary. cooling, which can be a limiting factor for its performance It has an effect on the cooling capacity of the towers.

Force, high environmental at relatively low daily temperatures more than their heat. Force used beyond that it also depends on the heating values of the fuel; for example as fuel when coal is used, the strength depends on the quality of the coal used. it is attached. A change in coal quality, for example, which occurs with the change of the power requirement and thus the steam flue gas, which has an effect on the (net) force of the device It can also cause a change in quantity.

The maximum possibly available power of the steam appliance an estimate by taking these conditions into account. forming a force fluctuation of the steam appliance, a for determining the cleaning instant or a cleaning cycle It provides the possibility of towing around the nominal value/bottleneck capacity.

With the method according to the invention, an additional load forecast current as a function of his/her needs and/or job needs. for determining the cleaning instant or a cleaning cycle considered as criteria, such that the efficacy angles in terms of the technical usability of the steam appliance in terms of determined optimum cleaning time and/or The optimum cleaning time determined according to the it can be transmitted depending on the load in terms of some of the surfaces.

Additionally or alternatively, the intensity of the cleaning process can be increased or decreased. The underlying idea is In the case of maximum load in the network, the force of the boiler is be desirable so you win in these timeframes load drop related to cleaning should be avoided. a cleaning and/or time frames available for a cleaning cycle energy in terms of full load optimization in accordance with the invention It can be delayed or optimized depending on the need.

That is, for example, the maximum load of an optimum cleaning moment lower when necessary, with a phase of need of the demand-based electricity charge in the load requirements. It may be delayed at a time so that it will fall into the steam appliance.

In other words, cleaning and cleaning, determined according to the need, in accordance with the invention. the lower power of the steam appliance resulting from it is up to date energy need and the energy fee derived from it, or depends on the current heat requirement.

Here, on the one hand, the process of pollution is constantly does not worsen and, on the other hand, that the use of the steamer a low expected strength loss, depending on cleanliness. realization of energy need in a way that falls into phases warranty is essential.

Here, to avoid the accident stalling unplanned a certain contamination that is allowed to the maximum should not be hung.

The above-described method is particularly effective with lignite coal. for use in fired boilers or steam appliances suitable because lignite coal has a high level of slag, contains large amounts of substances and has no effect on such steam devices. A process that depends on its degree is particularly important.

As the state-determining parameters of the steam device, the most at least the surface temperatures of the steamer and/or reheating degrees can be determined and/or measured. heating surface temperatures, for example, the state of contamination of the heating surfaces. can be used for determination. These are known for example can be determined through creation processes. of the fire field wall temperature, indicator for contamination status of the firepit can function as For example, the temperature of the heating surfaces It can also be measured by means of suitable temperature sensors.

Determination and monitoring of firepit temperatures e.g. DE known from patents. Beyond that, the heater in the last document A method for determining surface activity is also described. has been made.

Steam device in a preferred variant of the method according to the invention the function of the meteorological forecast data of the load forecast for is envisaged to be created. in certain weather conditions less electricity to the network from regenerative energy sources is fed, so that a completely safe load estimate can be estimated for several can be adjusted within a period of time known. A heat supply by the steam appliance load estimation, in case of a takes place depending on your needs. a load estimate It does not have to be created due to meteorological forecasts.

Load estimation eg industrial current and/or heat collector also due to its planned connection or disconnection. it can happen. For example, a production for aluminum production A high amount of electricity is required to operate the plant. It is heard that the acceleration of such a facility is expected. creates a load condition.

In the case of predictable strong load in the current network a nominal cleaning operation can be avoided and/or may be alleviated and/or postponed and/or shortened, in predictable `low load condition. a nominal cleaning The process can be pulled forward and/or intensified. available under the name of the nominal cleaning process in the sense of the invention, specific cleanup due to the activity estimation being executed instantly logical and desirable but definitively at this moment A non-essential cleaning process should be understood. Compulsorily This is what is obligatory at the time of cleaning that must be followed. cleaning is only possible before the heating surface below the specified minimum efficiency or when the heater in case the maximum allowable contamination of the surface is exceeded is a triggered cleanup process.

A specific cleaning cycle at a specific cleaning time applied; not to slide the cleaning moment when necessary here, but limiting the scope of cleaning in terms of surfaces to be cleaned or enlargement may also be envisaged. Cleaning intensity required cases, for example in the use of water pipe bellows, can be reduced by controlling the pressure or can be increased. Cleaning cycle name according to the present invention under should be understood the beginning of a cleaning cycle.

When a delayed nominal cleaning is concentrated particularly useful. That is, in the strong load phase of the current grid. a nominal that is avoided and realized at a later time permanent effect of cleaning on the heating surfaces. It is concentrated to prevent impurities.

Availability estimation and efficacy estimation neuronal It is particularly advantageous when models are created via

In addition, at least the input of the activity forecast and the load forecast parameters, which cleaning cycles are enabled and/or in a released fuzzy editor advantageous when used. depending on the duration of the process and its superficial coating. its wear is also fuzzy as an input parameter available in the editor.

Load forecasting preferably as electricity price diagnosis is displayed. Electricity price in case of a fuzzy arrangement Diagnosis as input parameter in fuzzy editor used. sootblower based on heater surface activity managed by control System or eg infrared camera technical cleaning with diagnostic systems such as cleaning systems need and technically optimized cleaning moment determined and control for the control of cleaning devices transmitted to the system. Technical cleanliness requirement, above cleaning resulting from activity estimation as described is the requirement.

Load estimation alternatively as heat demand estimation. for example seasonally or by industrial collectors can be created depending on whether it is connected or disconnected.

In a steam appliance (power plant) in accordance with the invention blog) load, cleaning and application planning a load adjuster evaluated and automated by Load as the adjuster, for example, with the appropriate software A scheme has been established for electronic data processing. it could be. Temporal and technical movement in the load adjuster area is determined and, for example, the price development in the electricity market and associated with demand. Price and demand here optimized, then high prices in the electricity market no reduced load as much as possible when dominating not permissive and cleaning schemes in low price phases A cleaning plan that controls Available in this section electricity and heat requirements are provided at the most affordable prices.

Fuel trend can also be included in this optimization.

originating from the electricity market or heat requirement. costs/fees are estimated, acceptable cleaning cycles are determined and the most suitable condition of both criteria is searched. and checked. Control of cleaning systems so that automatically diagnostic systems and/or control systems may take place through or take control as advice. can be forwarded to the field management team.

In an advantageous variant of the method according to the invention, a strong the predicted high of a rated cleaning operation during the load phase. shifting into an available time is foreseen. Here's a cleanup possible use of the steam device in the planning for the realization of maximum force is taken into account. This is particularly possible Availability estimate of higher maximum force with not yet found in it, but has changed for a short time, where the normally force-limiting parameter arises it is advantageous.

In another advantageous embodiment of the invention, in creating an availability estimate or updating especially the force of the steam appliance in the setting factors can be monitored and taken into account. These are for example the heating value of the fuel, the amount of fresh steam, the fresh steam temperature, reheater temperature, reheater pressure, reheater heater amount and/or cooling water temperature.

Steam based on load forecasting and availability forecast device for load-controlled power regulation. when the control plan is created and the control plan of the steamer It is advantageous when regulated in terms of strength through.

Thus, the determined actual control of the steam device is realized.

The power control of the steamer is customarily controlled by a generator. frequency regulation and secondary power regulation behind possible through In this way, the power adjustment is made to the steam device. electricity transmitted from a generator connected to a current grid occurs with power control.

Load forecasting, availability forecasting and activity forecasting created for periods measured by hours and days, for example from about 0 to 24 hours for the next day or a period of approximately 0 to 48 hours for the following days. for period n.

Control plan For example, for the mode of action of the steamer steam device in the form of a daily course plan as a movement plan after the adjustment takes place with the help of the control plan. can be given for one day; here is the control plan of the steam appliance gives the operating parameters for the power. for example, for a daily period or a 24-hour period plan of the current network of the control plan given for the period In line with this, it can be foreseen that it will check every fifteen minutes.

In addition, in the usability estimation, complementary power for the supply of options and/or control energy consideration of options can also be foreseen. complementary power options, in particular, at least from time to time steam, which allows a higher power but if necessary power associated with the lower degree of efficiency of the device are options. One of these complementary power options is example is disabling economizers. Thus, the effect It is aimed to increase the power for the loads of the grade.

In order to provide the control energy, the standard power bands where assistance can be provided can be specified in the following.

The method according to the invention is the full power of a steamer. potential, the rated power/bottlegas capacity of the steam appliance use in the sense of setting the maximum power on it gives the opportunity. The improved planability of the force also It offers a thinner security tape at the offered strength.

Nominal power of the steamer without estimation of availability a device that does not have a certain power band width around it. to provide unit power and to connect the steam device to the current network. this tape if required by load requirements It would be necessary to control it in width. a with the creation of the usability estimation, the steam appliance adjusting the power of the steam appliance above its nominal power, so that when planning a cleaning operation, the steam appliance it is possible to take into account the maximum possible power.

The invention provides another advantage that many steam devices and/or most balancing at least a steam appliance and control energy a facility to be provided within the framework of group management effects in timely consideration. to steam devices a demand for a load is basically to fully comply with the requirement and/or contribute to the network stability. reserve a certain part of their power (control energy) should be kept ready. These requirements leading an appropriate power within the framework of balancing group management Accordingly, the electricity generation and/or at least one steam generator for power regulation to provide heat of your device. and the control energy for the virtual balancing group A method by which a facility is summarized for the provision of has been provided. In the facility for the supply of control energy the basis in question, within a specified time interval, demand providing a predefined power that is sufficient on It can be any kind of energy producer that is in a state of being. Suitability decisive for the maximum force and maximum is the initial ramp possible to obtain the force. In particular, there is a promise in the facility for the supply of control energy. The subject is another steam device, a pumped collection power plant. station or powers that can be disabled.

The method according to the invention is thus a steam device or a steam current requirement and/or heat requirement for generating a load estimate as a function of a possible failure of the steamer as an estimate of availability. an estimate for the maximum power available in the figure steam generated and summarized for the balancing group devices with a maximum power and control energy facility to provide considered with a minimum force includes the creation of a control plan.

Contrary to this method of steam devices, until now that it can operate with maximum power and without any control offers the advantage that they do not have to offer energy. This is constantly due to the fact that a load change can be prevented steam devices are more economical in terms of plant wear. allows it to be used in

The fluctuations of the power of each steamer, random due to the effects of more than one steam appliance to a large extent. self-balanced or centralized by taking into account facility or facility to provide control energy in such a way balanced through facilities.

Control plan especially for future periods, for example created for periods measured by hours and days, for example from about 0 to 24 hours for the next day or a period of approximately 0 to 48 hours for the following days. for period I n.

Availability estimation, as noted above, parameters have a very large effect on the available power. environmental temperature and/or fuel set as a function of quality.

Preferably, within the method, the steam device or the steam The gross and/or net generator power of the devices is inspected.

Subtraction with other value in appropriate plant information oriented towards one of the two power values inspection is sufficient. To provide control energy The plant then detects a difference in production according to the control plan. will balance and the balancing group is always balanced like this will be set as follows.

In addition, in the usability estimation, complementary power for the supply of options and/or control energy consideration of options can also be foreseen. complementary power options, in particular, at least from time to time steam, which allows a higher power, but if necessary power associated with the lower degree of efficiency of the device are options. One of these complementary power options is example is disabling economizers. Thus, the effect It is aimed to increase the power for the loads of the grade.

Complementary force options, especially the control energy can be arranged to provide.

Claim 14 for force control of several steam appliances in the appropriate method, the steam during operation of the steam appliance and/or the use of water powered cleaning devices The previously described consideration also applies. From this perspective Reference is made to the previous description.

The invention will be explained below by means of an illustration; The drawings attached herein will be shown for reference.

It is the strength that it can truly display. cleaned, the maximum possible force cleaning falls during, for example 300 MW electrical rated power the type of cleaning process in a steam appliance with falls between about 15 and MW depending on

Cleaning, for example a cleaning in a firepit of the radiant heating surface arranged opposite the or more water pipe bellows.

Here, water flows through the fire area with high pressure. The radiant heater standing opposite to it is propelled to the surface, thus adhesions arranged here approximately or slightly pus can be resolved.

For current reference, cleaning of heating surfaces, soot secondary heating of the steamer by means of its blower can be envisaged as cleaning the surfaces.
