Please refer to both Figure 1A and Figure 1B. 1A is a block diagram of a smart soot blowing device 1 and a boiler 2 in accordance with an embodiment of the present invention. Fig. 1B is a side sectional view showing the boiler 2 in an embodiment of the invention.

The intelligent soot blowing device 1 is applied to the boiler 2 to perform soot blowing on the boiler 2. In one embodiment, the boiler 2 operates in accordance with the coal 201.

As shown in FIG. 1B, the boiler 2 includes a burner section 200, a furnace 202, a water wall tube 204, a primary superheater 206, a secondary superheater 208, a tertiary superheater 210, and a rear end superheat. The device 212, the reheater 214, and the fuel saver 216.

In operation, coal-fired 201 is supplied to the combustor section 200. The radiant heat generated by the combustion and the convective heat are used to heat (evaporate or superheat) the pressurized water in the water wall tube 204 to form a water wall of the furnace 202. The vapor in the water wall tube 204 is directed to the superheater section. The vapor is heated and introduced, for example, but not limited to, a steam turbine generator system and a condensing and watering system (not shown), and is comprised of a primary superheater 206, a secondary superheater 208, a tertiary superheater 210, and a rear superheater 212. And the reheater 214 is reheated. The high temperature pressurized water produced by the condensation and feedwater system is then received by fuel saver 216. In the fuel saver 216, the feed water will enter the water wall tube 204 and be preheated by the exhaust of the boiler.

The smart soot blowing device 1 includes a storage unit 100, an analyzing unit 102, a control strategy generating unit 104, a complex soot blowing unit 106, a complex detecting unit 108, and a complex control unit 110.

The storage unit 100 can be any storage medium such as a read-only memory (ROM), a flash memory, a magnetic disk, a hard disk, a compact disk, a flash drive, a magnetic tape, or a network accessible database. .

In one embodiment, the storage unit 100 stores a plurality of historical boiler operating parameters 101 and historical coal quality information 103.

The historical boiler operating parameters 101 may include, for example, but are not limited to, different temperatures in the boiler 2 such as the temperature of the furnace and steam, the power consumption of the boiler 2, the amount of coal used in the boiler 2, the power conversion efficiency in the boiler 2, the boiler 2 Cleanliness, soot blowing frequency and distribution of boiler 2, and sprinkling amount in boiler 2.

Historical coal quality component data 103 may include, for example, but not limited to, a ratio between different coal qualities. In an embodiment, the coal combustion may include, for example, but is not limited to, coal having slagging characteristics and coal having ash deposition characteristics. When the boiler 2 uses coal having slagging characteristics, cinders are easily generated. When the boiler 2 uses coal having a dust collecting property, it is easy to generate dust. In different use scenarios, coal combustion may contain coal with different characteristics.

The analysis unit 102 is configured to analyze the historical boiler operating parameters 101 and the historical coal quality composition data 103 for a particular time interval, such as, but not limited to, a one week or one month time interval. In one embodiment, the historical boiler operating parameters 101 and the historical coal quality component data 103 may be pre-processed prior to analysis to remove outliers, calibration time intervals, and normalize them.

Based on the analysis results, the analysis unit 102 determines the historical soot frequency in each region of the boiler 2 and the sootblowing relationship 105 between the historical coal components in the target power consumption of the boiler 2.

In various embodiments, the analysis unit 102 can use the historical boiler operating parameters 101 and the historical coal quality component data 103 as training data to determine the sootblowing relationship 105 by any machine learning method. Different types of models can be established depending on the operation of the boiler and the composition of the coal.

For example, when coal combustion contains more coal having slagging characteristics, coal slag tends to accumulate in the front end region of the boiler 2. In this case, if the front end region of the boiler 2 is frequently blown, the temperature of the boiler 2 will not be too high and the performance of the boiler 2 will be improved.

On the other hand, when coal combustion contains a large amount of coal having ash deposition characteristics, ash tends to accumulate in the rear end region of the boiler 2. In this case, if the back end region of the boiler 2 is subjected to frequent soot blowing, the temperature of the boiler 2 will not be too high and the efficiency of the boiler 2 will be improved.

In one embodiment, since the sootblowing control strategy 107 is generated in accordance with the sootblowing relationship 105, the sootblowing control strategy 107 will control the sootblowing behavior in accordance with the characteristics of the coal quality.

For example, when the proportion of coal having slagging characteristics to coal is greater than the first threshold, the soot control strategy 107 increases the soot frequency corresponding to the front end region of the boiler 2. When the proportion of coal having coal accumulation characteristics to coal is greater than the second threshold, the soot control strategy 107 increases the soot frequency corresponding to the rear end region of the boiler 2.
