1. Compressed air system for control instruments

The operation of a thermal power plant requires a large number of control instruments to support its operation, and the actions controlled by these instruments are all completed by compressed air;

Compressed air is mainly used for steam power operation and control instruments of steam boilers and generators. In recent years, it has achieved a transformation from physical operation to microprocessor control。

 

2. Ash removal for compressed air systems

The ash remover can be divided into negative pressure ash removal system, positive pressure ash removal system, low positive pressure ash removal system, and hydraulic ash removal system according to different pressures.

Among the four types of ash removal systems, the compressed air required for the positive pressure ash removal system mainly uses Hanzhong air compressor and bin pump to form a positive pressure in the ash conveying pipeline, thereby achieving the purpose of dust removal.

 

3. Plant Miscellaneous Compressed Air System

Due to the large number of equipment pipelines in power plants, power transmission requires high requirements for equipment pipelines, requiring the use of compressed air for mechanical maintenance.

 

4. Compressed air system for water treatment

In a thermal power plant, the steam wheel driven by high-pressure steam is converted into mechanical energy to drive an electric motor to generate electricity. High pressure steam requires a large amount of make-up water, so it requires a feedwater system.

There are several pneumatic diaphragm valves and pneumatic instruments between each water treatment system, which require compressed air to achieve. In addition, in the sewage treatment system of a water treatment system, compressed air is also required for sewage mixers and some pneumatic instruments.
