The acoustic temperature field measurement system is mainly composed of control cabinet, gas sound generating device, signal processing and controller, audio pickup, gateway and special computer for data processing. 

The acoustic temperature measurement system is composed of eight measuring points, and each detection has the functions of sound generation and reception at the same time, so the data conditions for two-dimensional temperature reconstruction analysis of furnace flue gas outlet can be realized. 

The hardware link configuration of 100m industrial Ethernet is adopted, the mature TCP/IP protocol is adopted to ensure the integrity and effectiveness of communication under the condition of large amount of data, and the local area network is used to build the network communication platform.

The seal gap control system is an automatic tracking and control system for the radial seal at the hot end of the preheater. The system uses a non-contact high temperature sensor to detect the seal gap of the sector plate and serves as the tracking control criterion of the system. 

The rotor deformation database is calculated according to the internal flue gas and air temperature of the preheater, which is used as the criterion of temperature tracking control of the system, and the absolute displacement sensor is used as the auxiliary control of temperature tracking.

The DZXL-VI optimized furnace tube leakage detection system is mainly composed of industrial computer, signal transfer box, solenoid valve controller and 4-20mA current output acoustic sensor.

The system is mainly composed of TV system, cooling protection system, advance and retreat servo system.

The TV system includes: high temperature pinhole lens, color camera, video cable.

The cooling protection system includes: control cabinet, cooling protection jacket, automatic protection circuit, furnace door mechanism, metal hose.

The advance and retreat servo system includes: electric actuator, control cabinet, remote operator, multi-core control cable.

Each boiler adopts the scheme of two camera assemblies; through the camera assembly, the two-color water level gauge installed on the An and B side of the boiler drum is displayed real-time and clearly on the color monitor in the centralized control room.

The UNIFLAME detector measures the amplitude and frequency of the target flame. 

In the process of setting the detector, the frequency that produces the best flame ON/OFF resolution is selected, and the appropriate frequency and sensor gain can be adjusted manually or automatically.

The operation of the IDD-II/IIU probe is aimed at the main combustion area of the burner, and the radiation energy emitted by the flame is either transmitted to the surface of the probe photosensitive element through a straight tube or wound optical fiber. The bias voltage of the lead sulphide photosensitive element in the IDD-II/IIU probe which receives the radiant energy is + 50VDC.

IFD100 intelligent flame detector system is mainly composed of system control cabinet, integrated chassis, flame signal detection sensor, signal processing module, communication management module, power module, optical fiber, installation casing and cooling air system.
