Specifically, most of the boiler NOx emission is caused by the fact that excessive air is added in the combustion process, so that nitrogen in the air is fully or insufficiently combusted, and the emission of nitrogen oxides exceeds the standard, and the heat in the boiler is consumed. Therefore, the environmental protection control device 400 detects the NOX emission amount of the boiler in real time during the combustion process of the boiler, and sends a corresponding control command to the combustion control device 300 when the NOX emission amount is greater than the NOX emission index, so as to perform corresponding control on the boiler through the combustion control device 300.

Specifically, the parameters for which the feed control device 500 is designed may include: the method comprises the following steps of bucket lifting full, bucket lifting operation, bucket lifting frequency, material layer thickness, grate rotating speed, grate frequency and grate operation. The feeding control device 500 can calculate the volume of fuel used in unit time according to the rotating speed of the grate, the thickness of the material layer and the width of the grate, so as to determine the operating frequency of the bucket elevator (because the bucket elevator is not weighed, the bucket elevator is full every time). After determining the operating frequency of the dipper, the combustion control device 300 may control the boiler accordingly.
According to an embodiment of the present invention, as shown in fig. 4, the boiler control system may further include: measurement parameter redundancy control apparatus 600.

The heat energy control device 100 and the combustion control device 300 can be connected through the data distribution management device 200 to share data, and meanwhile, effective data are uploaded to a virtual network disk through a GPRS module, so that the purpose of remote control is achieved.
Further, the redundancy detection of important parameters (operating parameters of the boiler, such as the amount of air blown by the boiler, etc.) can be performed by the measurement parameter redundancy control device 600, and if the operating parameters exceed preset parameters, an alarm signal is sent out to immediately transmit error events upwards, such as a device which is forcibly reset if the operating parameters are not processed for a long time. When the operation parameters exceed the control of the data model, the operation mode uploads the working conditions to require personnel to intervene under the condition of maintaining the existing operation working conditions.
As a possible implementation mode, the system can be controlled to operate in an upper computer monitoring mode. The system is provided with an operator station and an engineer station, two upper computers share resources and have different authorities, the heat energy control device 100 and the combustion control device 300 are provided with double communication settings and respectively transmit data to the data release management device 200 and an upper computer bus, and the engineer station is responsible for mathematical model establishment and configuration modification tasks.
