Description

This invention relates to a technique for the automatic regulation of the supply of fuel to the burners of a boiler unit.

The purpose of the invention is the development of the regulation process.

The drawing shows a structural diagram of the proposed system.

The system contains the first fuel regulator 1, the input of which is connected to the heat regulator 2, and the output to the regulating gate 3 of the distributor 4, the sensor 5 of the position of the regulating gate 3, the second fuel regulator 6, which is connected through a non-linear element 7 of the dead zone type with the sensor 8 of the power of the electric motor 9 of the mill 10, and the output is connected to the drive 11 of the working element of the feeder 12 of raw coal. The output of the regulator 2 is connected to the input of the second regulator 6, and the sensor 5 of the position of the regulating gate 3 is connected to the input of the first regulator 1.

The system works as follows. Editor O. Bugir

When the heat load of the boiler unit changes, the first regulator 1 of the fuel, having received a pulse from regulator 2, acts on the regulating gate 3 of the divider-doser 4, changes the fuel consumption to the burners of the boiler unit. The main regulation on fuel is carried out by the second regulator 6, having received a pulse from regulator 2 simultaneously with regulator 1, acts on the actuator 11 of the operating unit of the feeder 12 raw coal, changing the fuel consumption per mill 10 and, accordingly, on the boiler unit . Then, the input from the regulator 6 is fed through a non-linear element 7 of the dead zone type, a pulse from the power sensor 8 of the electric motor 9 of the mill 10. At the same time, the second fuel regulator 6 provides a zero-speed change in the performance of the mill 10 depending on the load change of the boiler 1 fuel.
