It should be noted that the steps shown in the flow chart of the accompanying drawings can be implemented in a computer system such as a set of computer-executable instructions and, although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0021] figure 1 It is a flowchart of a control method of a circulating fluidized bed unit according to an embodiment of the present invention, such as figure 1 As shown, the method includes the following steps:

[0022] Step S102, acquiring the total coal amount and actual power after a preset time delay.

[0023] Specifically, according to the pure delay of circulating fluidized bed units and the characteristics of unit energy balance, the total coal amount and actual power can be del...

Embodiment 2

[0072] According to an embodiment of the present invention, an embodiment of a control device for a circulating fluidized bed unit is provided.

[0073] Figure 5 It is a schematic diagram of a control device of a circulating fluidized bed unit according to an embodiment of the present invention, such as Figure 5 As shown, the device includes:

[0074] An acquisition module 51, configured to acquire the total coal amount and actual power after a preset time delay.

[0075]Specifically, according to the pure delay of circulating fluidized bed units and the characteristics of unit energy balance, the total coal amount and actual power can be delayed, and the specific delay time (that is, the above-mentioned preset time) can be determined by the sampling time and sampling individual The number determination, for example, can be 6-10 minutes, that is, at the current moment, the total coal quantity and actual power obtained are the total coal quantity and actual power of the cir...

Abstract

The invention discloses a control method and device of a circulating fluidized bed unit, a storage medium and a processor. The control method comprises the steps that the total coal quantity and actual power after preset time is delayed are acquired; according to the total coal quantity and the actual power which are acquired after the time is delayed, the unit dynamic corrected power coal consumption is generated; according to the unit dynamic corrected power coal consumption and target power, a first control signal of the coal supply quantity is generated; and according to the first controlsignal and the target power, the coal quantity of the circulating fluidized bed unit is controlled. The control method and device of the circulating fluidized bed unit, the storage medium and the processor, the technical problem that a control device of a circulating fluidized bed unit in the prior art cannot effectively adapt to the change of coal types or coal quality is solved.

Description

technical field [0001] The invention relates to the field of circulating fluidized bed unit control, in particular to a control method and device, a storage medium, and a processor for a circulating fluidized bed unit. Background technique [0002] Circulating fluidized bed (referred to as CFB) combustion technology, as a new generation of advantages of high efficiency, low pollution and wide adaptability of fuel, has been more and more widely used. The main difference between circulating fluidized bed boilers and pulverized coal boilers is the combustion mechanism. For pulverized coal furnaces, the heat released by combustion comes from the amount of coal that enters the furnace instantaneously. Once the coal supply is stopped, the combustion will stop soon. For circulating fluidized bed boilers, the heat generated by combustion mainly comes from a large amount of unburned coal in the boiler. Burning carbon as soon as possible, rather than the amount of coal added in an in...
