Abstract
The invention relates to a gas combustion automatic control system. The gas combustion automatic control system comprises an acquisition function module which receives and judges an acquisition function module signal, the acquisition function module is connected with an adjusting function module connected with a manually operated device MAN additionally connected with a boiler fuel gas combustion adjusting valve, and the boiler fuel gas combustion adjusting valve is connected with a boiler and adjusts the boiler. According to the gas combustion automatic control system provided by the invention, the influence on a boiler combustion fuel caused by the pressure fluctuation due to external factors can be automatically adjusted and processed, therefore the waste and environmental pollution problems caused by gas bleeding can be prevented by auto-combustion movable control.
Description
Technical field
The invention belongs to industrial coal gas boiler technical field, relate to a kind of automatic burner control system and the application thereof that can control gas boiler.
Background technology
Generally, in steel industry smelting process, auxiliary product coal gas can be produced, except personal and heating furnace use outer coal gas to carry out consuming and pressure adjustment mainly through industrial gas boiler combustion on a small quantity.Because industrial gas boiler combustion mainly regulates by manual operation, and manual operation there will be gas pressure that operation causes not in time too high when coal gas emptying waste, gas pressure affect the problems such as heating furnace user use when too low, therefore, prior art is utilized to regulate gas pressure by the automatic control combustion of Industrial Boiler.Specifically, the signal that automaton is first calculated by acquisition function module sends into regulatory function module, and regulatory function module carries out the manual operator MAN controlling to export to according to outside set-point, adopts to calculate to realize automatically regulating, and reaches automatic control.
Summary of the invention
For overcoming above-mentioned technical disadvantages, the invention provides a kind of automatic burner control system and application thereof, the impact of the pressure oscillation generation that can automatically regulate process boiler combustion fuel to cause due to extraneous factor, thus the waste and problem of environmental pollution that control to avoid coal gas diffusion to cause is moved by spontaneous combustion.
The present invention solves the technical method that its technical problem adopts: a kind of automatic burner control system, comprise one and receive acquisition function module by signal and the acquisition function module judged, this acquisition function module and regulatory function module are connected, this regulatory function module is connected with manual operator MAN again, the another control valve that burns with boiler coal gas of manual operator MAN is connected, and burn control valve and boiler of boiler coal gas is connected and regulates boiler.
An application for automatic burner control system, the steps include:
Acquisition function module is carried out conversion to mensuration gas pressure and is calculated, and exports the 1st signal according to result of calculation to regulatory function module; Regulatory function module to acquisition function module conveying come the 1st signal automatically follow outside set-point control and to manual operator MAN export the 2nd signal; Manual operator MAN is converted to control instruction to the 2nd signal regulating functional module to export and exports the 3rd signal to boiler coal gas burning control valve, directly controls boiler coal gas burning control valve and automatically adjust after manual operator MAN exports, thus control combustion; The 1st signal and the regulatory function module-external set-point that meanwhile export when acquisition function module are compared, and when outside set-point is greater than the 1st signal, the 2nd signal that regulatory function module exports controls to turn down producer gas by manual operator MAN and to burn control valve; When outside set-point is less than the 1st signal, regulatory function module export the 2nd signal by manual operator MAN control open large producer gas burning control valve, until reach acquisition function module export the 1st signal and regulatory function module-external set-point in a basic balance.
Described manual operator MAN has excision module and fault automatic decision module automatically, wherein automatically excise module and introduce boiler capacity setting value, failsafe valve signal, boiler oxygen content setting value, any introducing signal exports will trigger loop fault judgment means, and manual operator exits and automatically controls and send alarm signal.
The invention has the beneficial effects as follows: the impact of the pressure oscillation generation that can automatically regulate process boiler combustion fuel to cause due to extraneous factor, thus moved the waste and problem of environmental pollution that control to avoid coal gas diffusion to cause by spontaneous combustion.
Accompanying drawing explanation
Fig. 1 is structure frame structure schematic diagram of the present invention;
Detailed description of the invention
Below in conjunction with embodiment, the present invention is further described.
See Fig. 1, a kind of automatic burner control system, comprise one and receive acquisition function module by signal and the acquisition function module judged, this acquisition function module and regulatory function module are connected, this regulatory function module is connected with manual operator MAN again, the another control valve that burns with boiler coal gas of manual operator MAN is connected, and burn control valve and boiler of boiler coal gas is connected and regulates boiler.
An application for automatic burner control system, the steps include:
Acquisition function module is carried out conversion to mensuration gas pressure and is calculated, and exports the 1st signal according to result of calculation to regulatory function module; Regulatory function module to acquisition function module conveying come the 1st signal automatically follow outside set-point control and to manual operator MAN export the 2nd signal; Manual operator MAN is converted to control instruction to the 2nd signal regulating functional module to export and exports the 3rd signal to boiler coal gas burning control valve, directly controls boiler coal gas burning control valve and automatically adjust after manual operator MAN exports, thus control combustion; The 1st signal and the regulatory function module-external set-point that meanwhile export when acquisition function module are compared, and when outside set-point is greater than the 1st signal, the 2nd signal that regulatory function module exports controls to turn down producer gas by manual operator MAN and to burn control valve; When outside set-point is less than the 1st signal, regulatory function module export the 2nd signal by manual operator MAN control open large producer gas burning control valve, until reach acquisition function module export the 1st signal and regulatory function module-external set-point in a basic balance.
Described manual operator MAN has excision module and fault automatic decision module automatically, wherein automatically excise module and introduce boiler capacity setting value, failsafe valve signal, boiler oxygen content setting value, any introducing signal exports will trigger loop fault judgment means, and manual operator exits and automatically controls and send alarm signal.
The invention has the beneficial effects as follows: the impact of the pressure oscillation generation that can automatically regulate process boiler combustion fuel to cause due to extraneous factor.Thus the waste and problem of environmental pollution that control to avoid coal gas diffusion to cause is moved by spontaneous combustion.
