Abstract
The boiler flame center controlling system includes several image transmitting fibers, several CCD camera heads, color image monitor, image card, communication card, computer, display CRT, keyboard, combustion controlling system, fuel valve, wind valve and several burners. Through the whole hearth flame image processing and calculation, the frame center is determined and control signal is output to regulate the secondary draft, the primary draft and output of the burners so as to maintain the optimal burning position of the flame center area in different load.
Description
The present invention relates to a kind of boiler flame center regulator control system, especially relate to a kind of boiler flame center regulator control system that adopts video technique regulation and control boiler flame center.Belong to the boiler thermal technology automation field that burns.
Boiler is a kind of large-scale combustion apparatus, controls the damage that bad combustion centre district will cause a large amount of energy wastes and heat power equipment, even causes accident.At present, the boiler operatiopn personnel are because of can't specifically detecting the uncontrollable flame combustion central point of ignition center zone position in the burner hearth exactly, and boiler still is in blind burning state.
The objective of the invention is video technique and computer technology be incorporated into a kind of boiler flame center regulator control system is provided in the control system.It can be handled and computing according to the vision signal process that several gamma cameras send, come out in flame combustion center and boiler characteristic area position judgment, controlling each burner by control output exerts oneself and air distribution, flame kernel is controlled at when different load in the zone of safety economy, thereby improves the economy and the security of boiler combustion.
The objective of the invention is to realize by following technical solution.Design a kind of boiler flame center regulator control system, it comprises: some biographies resemble optical fiber, some CCD stylus, colour picture monitor, visual card, address card, computer, display CRT, keyboard, combustion control system, fuel valve, air door and some burners; Described biography resembles optical fiber one end and inserts in the burner hearth, and the other end links to each other with the CCD stylus; The vision signal one tunnel of CCD stylus output is sent to colour picture monitor, and the digital imagery treatment system of being made up of image card, address card, display CRT and keyboard is sent on another road; Wherein the output signal of address card is as the input signal of combustion control system, and the output signal of combustion control system is controlled fuel valve, air door and burner respectively.
In the such scheme, comprise in the described digital imagery treatment system: gather module that vision signal and digitized module, processing digital signal draw the module of flame characteristic district scope and flame combustion center, compare with modeling parameters, judge whether the module of adjusting the control signal of secondary air register and each burner in the module and the output of specified scope.
The present invention adopts to pass and resembles optical fiber and several industrial gamma cameras, and full furnace flame image is sent into display system and combustion centre's control system.Display system shows the combustion case of combustion centre; Combustion centre's control system is handled computing with the picture intelligence process of flame combustion, judges the ignition zone temperature field, determines combustion centre, controls the situation of exerting oneself of each burner, and flame ignition center district is controlled in the scope of appointment according to the different load situation.The present invention adopts automatic correcting method to determine the physical location of flame in burner hearth, and is not passed the influence of the slight change that resembles fiber position.The present invention adopts the characteristic point in the burner hearth to demarcate the position of flame kernel, and the mode of employing modeling will wait combustion centre district and the burning energy level modeling under the load efficiently and deposit in the native system.By flame digital image and model contrast operation control wind of each burner and secondary wind, make flame kernel district energy level and position satisfy requirement under this load.
Boiler flame of the present invention center regulator control system has the following advantages compared with prior art:
1, the present invention uses video technique and computer technology, makes the control in combustion centre district become possibility, the history of the blind burning of boiler that is through with.
2, overcome the problems that blind burning state brings, improved the economy and the security of boiler combustion, accomplished not only energy-conservation but also environmental protection.
Below in conjunction with drawings and Examples, further specify the present invention.
Fig. 1 is the composition schematic diagram of boiler flame center regulator control system;
Fig. 2 is a computer program flow diagram in the system shown in Figure 1;
Fig. 3 is the fundamental diagram of system shown in Figure 1.
Fig. 1 to Fig. 3 illustrates structure of the present invention and operation principle.Referring to figs. 1 through Fig. 3, native system comprises: some biographies resemble optical fiber 1, some CCD stylus 2, colour picture monitor 3, image card 4, address card 5, computer 6, display CRT7, keyboard 8, combustion control system 9, fuel valve 10, air door 11 and some burners 12; Described biography resembles optical fiber 1 one ends and inserts in the burner hearth 13, and the other end links to each other with CCD stylus 2; The vision signal one tunnel of CCD stylus 2 output is sent to colour picture monitor 3, another road be sent to by image card 4, address card 5, display CRT7 and keyboard 8 form digital imagery treatment system 100; Wherein the output signal of address card 5 is as the input signal of combustion control system 9, and the output signal of combustion control system 9 is controlled fuel valve 10, air door 11 and burner 12 respectively.
In the such scheme, to resemble optical fiber overheated in order to prevent to pass, and passes and resemble optical fiber 1 peripheral hardware cool air hose 14.
In the such scheme, overheated for preventing the CCD stylus, CCD stylus 2 places are provided with overtemperature protection system 15.
Comprise in the digital imagery treatment system 100 in the native system: gather module 103 that vision signal and digitized module 101, processing digital signal draw the module 102 of flame characteristic district scope and flame combustion center, compare with modeling parameters, judge whether the module 105 of adjusting the control signal of secondary air register and each burner in the module 104 and the output of specified scope.
