Abstract
A single-nozzle combustion control system for boiler is composed of image transmitting optical fibre, CCD camera head, colour image monitor, image card, industrial PC, CRT, single-nozzle combustion controller, and single-nozzle secondary damper. Its advantages are high overall efficiency of boiler, and reduced exhaust.
Description
The present invention relates to a kind of single-burner combustion control system for boiler, especially relate to a kind of single-burner combustion control system for boiler that adopts video technique regulation and control boiler combustion.Belong to the boiler thermal technology automation field that burns.
At present, boiler is in blind burning state, and the operations staff can't be according to the independent secondary air register of each burner combustion state control.The one, can't monitor each burner combustion situation, the 2nd, can't control the secondary air register of each burner according to combustion position.So the burning economy of each nozzles is not high, cause the boiler whole efficiency not high, for large-scale combustion apparatus, can cause very big energy waste, also have influence on security simultaneously.
The purpose of this invention is to provide a kind of single-burner combustion control system for boiler.It utilizes video technique and computer technology, the single nozzles vision signal that collects is carried out the digital processing line number word arithmetic of going forward side by side, thereby control single nozzles secondary air register, it is fully economical that each burner combustion is got, and economy and the security to whole boiler combustion is improved like this.
The objective of the invention is to realize by following technical solution.Design a kind of single-burner combustion control system for boiler, it comprises: pass and resemble optical fiber, CCD stylus, colour picture monitor, single-burner combustion control system image card, Industrial PC Computer, display CRT, single-burner combustion control device and single nozzles secondary air register; Described CCD stylus resembles optical fiber connector with biography and is connected, it is exported one the tunnel and connects colour picture monitor, another road connects single nozzles digital imagery treatment system of being made up of single-burner combustion control system image card, Industrial PC Computer and display CRT, its output enters the single-burner combustion control device, and single nozzles secondary air register is controlled in the latter's output.
In the such scheme, comprise in described single nozzles digital imagery treatment system: gather module that vision signal and digitized module, processing digital signal draw the module of flame characteristic district scope and burning energy level, compare with modeling parameters, judge whether to meet the module of modeling standard and the module that the control signal of secondary air register is adjusted in output.
The burning of fuel has certain characteristic area during nozzles spray combustion.For coal dust at first is unburned black dragon, is the burning of fugitive constituent then, is the burning of carbon in the coal dust at last.Other fuel also have similar feature.Gamma camera is delivered to Industrial PC Computer with the image of single-burner combustion.Because under certain load, these characteristic areas will have certain scope, and computer is regulated the aperture of secondary air register according to the image feature that obtains, thereby burning is remained in certain characteristic area scope, simultaneous computer is also calculated the energy level of burning, as means of regulating secondary air register.The present invention adopts biography to resemble optical fiber and the CCD gamma camera is sent single nozzles flare up fire into colour picture monitor and single nozzles digital imagery treatment system, colour picture monitor is responsible for showing the single-burner combustion situation, single nozzles digital imagery treatment system is responsible for signal is carried out digitized processing and compares reference with modeling under the different load, the control signal of secondary air register is adjusted in computing and output, make single-burner combustion more fully economical, reach the standard of modeling.So-called modeling is exactly most economical image feature and the burning radiation energy grade (or claiming gray level, energy level) of single nozzles under the different load that deposits in system in advance.
Single-burner combustion control system for boiler of the present invention has the following advantages compared with prior art:
Owing to can accomplish each nozzles is monitored in real time and controlled, will improve the whole efficiency of boiler; Discharging is reduced, and not only energy-conservation but also environmental protection can also improve the security of operation.
Below in conjunction with drawings and Examples, further specify the present invention.
Fig. 1 is the composition schematic diagram of single-burner combustion control system for boiler;
Fig. 2 is a computer program flow diagram in the system shown in Figure 1.
Fig. 1 and Fig. 2 illustrate the structure of single-burner combustion control system for boiler of the present invention.See figures.1.and.2, it comprises native system: pass and resemble optical fiber 1, CCD stylus 2, colour picture monitor 3, single-burner combustion control system image card 4, Industrial PC Computer 8, display CRT 5, single-burner combustion control device 6 and single nozzles secondary air register 7; Described CCD stylus 2 resembles 1 terminal connection of optical fiber with biography, it is exported one the tunnel and connects colour picture monitor 3, another road connects single nozzles digital imagery treatment system 100 of being made up of single-burner combustion control system image card 4, Industrial PC Computer 8 and display CRT 5, its output enters single-burner combustion control device 6, and single nozzles secondary air register 7 is controlled in the latter's output.
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 11.
Comprise in single nozzles digital imagery treatment system 100: gather module 103 that vision signal and digitized module 101, processing digital signal draw the module 102 of flame characteristic district scope and burning energy level, compare with modeling parameters, judge whether to meet the module 104 of modeling standard and the module 105 that the control signal of secondary air register is adjusted in output.
Because single nozzles flame combustion has certain brightness degree and characteristic district, so the present invention uses video technique single nozzles flame picture is carried out digital processing, obtain their burning grade and characteristic district, and compare with the characteristic district and the energy level of economic modeling, reference, by the control signal of a single nozzles secondary air register of computing output, the burning that makes each burner more fully, more economically.
