Automatic Control of Boiler method of the present invention adopts the steam pressure in steam pressure sensor collection combustion chamber, gathers the vapor (steam) temperature in combustion chamber, gathered the oxygen concentration at combustor exit place by flue gas detector with steam temperature sensor, carbonomonoxide concentration, gas concentration lwevel, nitric oxide concentration, content of nitrogen dioxide, sulfur dioxide concentration, flue gas detector processes after gathering primary data automatically, exports following parameter: gas concentration lwevel, carbonomonoxide concentration, sulfur dioxide concentration, combustion efficiency value, excess air, flue gas loses, the dew point of special fuel, oxynitrides content etc., above-mentioned each sensor is connected with central controller respectively, the data collected is transported to central controller, and result compared with the parameter set, is fed back to feeding conveyor the data collected by central controller, primary air fan, overfire air fan, fire grate governor and air-introduced machine, adjust the operational factor of each parts, makes boiler operatiopn in optimum state, the generation of decreasing pollution thing.

Fig. 2 and Fig. 3 is respectively function structure chart and the flow chart of boiler pressure control.In burning control steps, the force value that central controller reception steam pressure sensor records also contrasts with the pressure limit preset; When pressure is lower than the pressure limit preset, increases the rotating speed of primary air fan, fire grate governor and feeding conveyor, reduce the rotating speed of air-introduced machine, until reach default pressure limit simultaneously; When pressure is higher than the pressure limit preset, reduces the rotating speed of primary air fan, fire grate governor and feeding conveyor, increase the rotating speed of air-introduced machine, until reach default pressure limit simultaneously.

Specifically, steam pressure sensor conversion current signal through A/D module to central controller, central processing unit receives pressure signal, if pressure is lower than the pressure limit preset, then by regulating the frequency converter of primary air fan to increase primary air fan rotating speed, by regulating the frequency converter of air-introduced machine to reduce air-introduced machine rotating speed, by regulating the frequency converter of feeding conveyor to increase feeding conveyor rotating speed, the frequency converter of governor is arranged to increase fire grate governor rotating speed by regulating stove, and then make pressure increase, reach critical field; If pressure higher than the pressure limit preset, then can make pressure drop by contrary adjustment, reach setting range.

Fig. 6 and Fig. 7 is respectively function structure chart and the flow chart of Oxygen control.In flue gas inspection step, the oxygen detection module in flue gas detector detects the oxygen concentration in flue gas and institute's measured value is inputted central controller; In burning control steps, the oxygen density value that central controller reception flue gas detector records also contrasts with the oxygen concentration range preset, and when the oxygen concentration of flue gas is too high, reduces post-blast machine rotating speed until reach default oxygen concentration range.

Fig. 8 and Fig. 9 is respectively function structure chart and the flow chart of hydrocarbon control.In flue gas inspection step, the hydrocarbon detection module in flue gas detector detects the carbon monoxide in flue gas and gas concentration lwevel and institute's measured value is inputted central controller; In burning control steps, central controller receives the carbon monoxide that records of flue gas detector and carbon dioxide concentration value and the ratio of the two and the ratio range preset is contrasted, when the concentration proportion of carbon monoxide and carbon dioxide is too high, reduce the rotating speed of feeding conveyor and fire grate governor, increase the rotating speed of primary air fan until reach default ratio range simultaneously.

Specifically, carbonomonoxide concentration adopts electrochemical sensor to detect, and carbon dioxide adopts NDIR sensor to detect, and testing result is with CO/CO 2form be delivered to central controller, what in ratio lower proof combustion chamber, burning was carried out is more abundant, if ratio is too high, then shows that burning is insufficient or supply hypoxgia, the rotating speed of feeding conveyor, fire grate governor and primary air fan need be regulated, increase fuel combustion time and oxygen-supplying amount.

In addition, carbon monoxide sensing protector is also provided with in flue gas detector, when carbonomonoxide concentration in flue gas exceeds CO sensor measurement scope (> 4000ppm), CO sensor can cut out automatically, and the air douche pump meeting unlatching automatically that instrument is built-in, extract fresh air and be supplied to CO sensor, realize real time protection; When carbonomonoxide concentration is lower than 1600ppm, flushing pump will quit work, and measurement restarts.The normal amount cls analysis of other sensors can not be had influence in this process.

Figure 10 and Figure 11 is respectively function structure chart and the flow chart of oxynitrides control.In flue gas inspection step, the oxynitrides detection module in flue gas detector detects the nitric oxide in flue gas and content of nitrogen dioxide and institute's measured value is inputted central controller; In burning control steps, central controller receives the concentration value of the nitric oxide that records of flue gas detector and nitrogen dioxide and the concentration value recorded and the concentration range preset is contrasted, when the concentration value recorded is too high, reduce the rotating speed of primary air fan, overfire air fan and fire grate governor until reach default concentration range.

Specifically, nitric oxide and content of nitrogen dioxide adopt electrochemical sensor to detect, and testing result is with NO xrepresent.NO xas the air pollutants of a quasi-representative, concentration is more low better, as the NO that burning produces xtime too high, by regulating oxygen-supplying amount, regional hypoxia environment can be created, makes it to be reduced to N 2.

Sulfur dioxide mainly adopts electrochemical sensor to detect, with SO 2concentration is that output signal is sent to central controller, because the chemical property of sulfide, the adjustment not in combustion process can reduce, and need based on fuel, combustion case to adopt before different burnings desulfurization or desulfurization industry after burning, this control system is for SO 2concentration is based on monitoring, if its concentration is far more than normal combustion standard, then system can send instruction, by automatically controlling to transfer Artificial Control to, checks SO 2concentration over-standard reason also takes corresponding pollution treatment measure.

More than that preferred embodiment of the present invention is illustrated, but the present invention is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent variations or replacement under the prerequisite without prejudice to spirit of the present invention, and these equivalent distortion or replacement are all included in the application's claim limited range.
