Technical terms used in the examples of the present application are explained as follows:
oxygen (or oxygen-enriched) refers to higher purity oxygen with a purity of 95% (volume fraction) or more.
The recirculated flue gas refers to flue gas which is circulated back from a dust remover or a flue gas condenser.
The oxygen-enriched combustion air supply system is used for supplying air quantity required by stable combustion of the combustion system in an oxygen-enriched combustion mode, wherein the air quantity supply system comprises a circulating air duct, an oxygen supply air duct, a valve and a flowmeter.
The oxygen-enriched combustion air supply system comprises a circulating flue gas valve 5, an oxygen valve 6, a circulating fan 4 and a pipeline connected between the devices.
The flue gas circulation multiplying power refers to the ratio of the total volume flow of the circulating flue gas to the total volume flow of the wet flue gas at the outlet of the hearth.
The volume and the components of the oxygen-enriched combustion furnace inlet gas (circulating flue gas and oxygen) are greatly different from those of the conventional air combustion, compared with the air combustion, the oxygen-enriched combustion air supply system needs to respectively convey the recirculating flue gas and the oxygen, and the control structure is more complicated. In the operation process of the boiler 1, various conditions may occur to cause the oxygen-enriched combustion air supply system to follow the change, and the air supply adjustment cannot be completed quickly and stably, so that the heat exchange condition inside the boiler 1 may be influenced, the steam parameter at the outlet of the boiler 1 is changed, and the normal operation of the whole boiler 1 and even the whole power plant is finally influenced.
Based on the above, the embodiment of the application provides a control method of an oxygen-enriched combustion air supply system, and an optimal automatic control scheme of the oxygen-enriched combustion air supply system is designed, so that the system can transition rapidly and stably, and the stability of heat transfer performance and the safety of pulverized coal conveying are ensured.
FIG. 1 is a schematic diagram of an oxycombustion apparatus provided in an embodiment of the present application. As shown in fig. 1, the apparatus involved in the apparatus environment to which the method for controlling an oxycombustion air supply system according to the embodiment of the present application may be applied: the system comprises a boiler 1, an induced draft fan 2, a chimney 3, a circulating fan 4, a circulating flue gas valve 5, an oxygen valve 6 and an air separation system 7.
The control equipment which has the adjusting function on the oxygen-enriched combustion air supply system in the equipment can be a circulating fan 4, a circulating flue gas valve 5 and an oxygen valve 6. The principle of the embodiment of the application lies in determining the influence of the control equipment on the oxygen-enriched combustion air supply system, so that the oxygen-enriched combustion air supply system can be accurately and automatically controlled.
FIG. 2 is a flow chart of a method for controlling an oxycombustion air supply system according to an embodiment of the present disclosure; as shown in fig. 2, a method for controlling an oxycombustion air supply system according to an embodiment of the present application may include: s101, determining a control parameter set of a plurality of control devices in an air supply system in an oxygen-enriched combustion mode; s102, performing closed-loop disturbance test on a plurality of control devices by adopting a control parameter set according to a control requirement; and S103, selecting a group of control parameters from the control parameter set to automatically control each control device.
Based on the scheme, the influence of the control equipment on the oxygen-enriched combustion air supply system can be determined by carrying out closed-loop disturbance test on the plurality of control equipment, so that the oxygen-enriched combustion air supply system can be accurately and automatically controlled.
In the embodiment of the present application, the boiler 1 may be operated in the air combustion mode for a certain period of time, and then the method may be performed after switching from the air combustion mode to the oxycombustion mode. Alternatively, after the boiler 1 is operated to be stable under the air combustion condition, the air input is gradually stopped, the oxygen enrichment is input, and a part of flue gas is circulated, so that the boiler 1 is switched from the air combustion mode to the oxygen enrichment combustion mode. The oxygen-enriched gas may be high-concentration oxygen gas separated by the air separation system 7, but may be obtained in other manners.
Optionally, the control parameter set may be determined by a relay feedback test method: for example, when the state of the oxygen-enriched combustion air supply system is adjusted, the circulating air volume and the actual circulating air volume form a deviation, different amplitudes (1%, 2%, 3%, 4%, 5%) are set through a closed-loop design, and are applied to the circulating flue gas valve 5 through the proportional-integral-derivative controller and the delay controller, so that the opening of the circulating flue gas valve 5 is adjusted, and the flow of the circulating flue gas is adjusted. Through the test, a circulating air volume control parameter set under different conditions is obtained.
Optionally, the control method in the embodiment of the present application includes: and performing a relay feedback test on each control device, determining a closed loop steady-state gain constant of each control device according to a relay feedback test result, forming the closed loop steady-state gain constants into a relative gain matrix, and calculating a control parameter set of the plurality of control devices according to the relative gain matrix.
In the process, the result of the relay feedback test can be obtained by setting an amplitude limit and a closed-loop control design.
The relative gain matrix is a matrix composed of closed loop steady state gain constants, and parameters for evaluating the performance of the controller, such as stability and sensitivity, can be calculated by the matrix. Through the closed-loop disturbance test, a closed-loop steady-state gain constant of the control device can be obtained, specifically, the closed-loop steady-state gain constant is a ratio of a change value of the control parameter to a change value of the control device, that is, the closed-loop steady-state gain constant is the change value of the control parameter/the change value of the control device.
Closed loop steady state gain constants of a circulating flue gas valve 5 and an oxygen valve 6 in the oxygen-enriched combustion air supply system can be obtained through calculation, wherein control parameters refer to flue gas circulation multiplying power, oxygen concentration and opening of a circulating fan valve, and change values of control equipment refer to flue gas circulation flow and oxygen flow. And forming a relative gain matrix by using the closed-loop steady-state gain constants, and calculating to obtain the control performance parameters of each control device.
In the embodiment of the application, the control requirement is that the oxygen-enriched combustion air supply system can relatively quickly respond to and return to the set point and the instruction value under closed-loop control, and the result error is less than 5%, namely, the oxygen-enriched combustion air supply system not only can quickly respond to changes, but also can resist external disturbance within a certain range and shows good robustness. According to the control requirements, through closed-loop disturbance testing, each control device can be automatically adjusted and mutually influenced, and finally a new balance point is reached, so that the control response characteristic of the control parameters is obtained.
In the embodiment of the present application, since the control parameter set of each control device is different, the control response characteristic of the control parameter is also different. And determining the optimal control parameters of each control device through a closed-loop disturbance test according to the control requirements. For example, when the load of the boiler 1 is reduced by 2% in 1 minute, the circulating air volume and the oxygen volume are both reduced by 2%, and when the control parameters determined under high amplitude are selected simultaneously, the changes of the circulating air volume and the oxygen volume are overlapped, so that the air volume of the oxygen-enriched combustion air supply system exceeds the error requirement less than 5% provided by the control requirement; when the control parameters determined at low amplitudes are simultaneously selected, the response times are also superimposed, resulting in failure to meet the rapid response characteristics in the control requirements. Therefore, by the closed-loop disturbance test, the optimal control parameter of each control device is selected.
In the embodiment of the application, the oxygen-enriched combustion air supply system adopting the control parameter set is tested through working condition disturbance. Optionally, the oxygen-enriched combustion air supply system adopting the control parameters in the control parameter set can be tested through multi-factor working condition disturbance, so that the test of the automatic control performance of different control devices is realized.
In some embodiments, the condition disturbance may include a step disturbance, a sine-like disturbance, and an oscillating disturbance, and embodiments of the present application may employ at least one of the above types of condition disturbances. Based on the above arrangement, during the normal operation of the boiler 1, the automatic control performance of the control combination can be comprehensively obtained by performing the test under the multi-factor disturbance.
In the embodiment of the present application, the controller of the oxycombustion air supply system includes a proportional-Integral-derivative (PID) controller and a delay unit. And setting a proportional integral derivative controller and a delay controller according to the control parameters in the control parameter set, setting the proportional integral derivative controller, and further controlling a plurality of control devices by using the set proportional integral derivative controller.
In some embodiments, the proportional integral derivative controller may be tuned using the Zielger-Nichols criterion. The above steps may be prepared for closed loop testing. The Zielger-Nichols criterion is a control criterion in a parameter tuning method of a proportional-integral-derivative controller, and reference may be made to related technologies, which are not described in detail herein.
In summary, the control method of the oxygen-enriched combustion air supply system in the embodiment of the application has the following advantages:
by determining the oxygen concentration, the circulation multiplying power and the opening of the valve of the circulation fan as control parameters, the operation safety and the stability can be ensured at the same time.
Through closed-loop disturbance test, response performance of the circulating flue gas valve 5 and the oxygen valve 6 to control indexes is obtained, disturbance tests with different time lengths and variation amplitudes are carried out, and control performance of different control combinations can be comprehensively tested, so that a more reliable conclusion can be obtained.
