What is the air compressor room of a power factory?

The air compressor room of a power plant is a key facility to maintain the normal operation of the power plant, and its core functions are closely related to the application of compressed air. The following is a detailed analysis:

1. The core functions of the air compressor room

1. power supply
   The air compressor room compresses atmospheric pressure into high-pressure gas through an air compressor to provide power source for power plant equipment. For example:
   • Drive pneumatic valves and actuators (such as control bridge systems) to ensure stable operation of the generator set.
   • Support the boiler combustion system, where compressed air and fuel are mixed and combusted to produce high temperature and high pressure steam to drive the steam turbine.
2. Auxiliary process support
   • water treatment system: Pneumatic diaphragm valves and instruments rely on compressed air to ensure boiler supply water and wastewater treatment processes.
   • ash removal system: The positive pressure ash removal system conveys coal ash through compressed air to improve ash removal efficiency.
   • equipment operation and maintenance: Provide air supply to pneumatic tools and maintenance equipment, support machine maintenance and pipeline purging.
3. System stability guarantee
   The air storage tank balances the air load, reduces frequent starts and stops of the air compressor, and ensures stable air pressure; air treatment equipment (dryers, filters) purifies the compressed air and prevents impurities from polluting the equipment.

2. Specific application scenarios of compressed air

3. Equipment composition of the air compressor room

1. air compressor(Core equipment)
   • Type: Screw type (efficient, low-noise) is mainly used, piston type or centrifugal type is used in some scenes.
2. air storage tank
   • Function: Store compressed air, stabilize air pressure, and separate water and oil.
3. air handling system
   • Dryer (freezing/adsorption), filter (primary/precision), oil-water separator.
4. cooler
   • Air-cooled or water-cooled type reduces the temperature of compressed air and protects equipment.
5. control and monitoring system
   • Pressure sensors, flow sensors, automated control systems.
6. safety equipment
   • Safety valve, fire-fighting equipment, ventilation device, alarm system.

4. Key points of air compressor room management

1. safety Code
   • Special equipment such as gas tanks must be inspected regularly, and extended use is strictly prohibited.
   • Operators need to have certificates and wear protective equipment (helmets, protective clothing) when entering the machine room.
2. daily maintenance
   • equipment inspection: Check the operating status of cables, pipelines, and equipment, and record key parameters.
   • supplies replacement: Regularly replace oil, oil and gas separators, and filters (such as the first replacement after 500 hours for a new machine).
3. environmental management
   • Keep the machine room dry and ventilated, and control the temperature (≤40℃) to prevent dust from entering.
   • Establish an entry and exit registration system to prohibit irrelevant personnel from entering.

5. Typical problems and handling

• Compressed air contains water: Check the function of the dryer and replace the failed desiccant.
• unstable air pressure: Clean up stagnant water in the air storage tank and check the operating efficiency of the compressor.
• device to overheat: Clean up dust in the cooler and ensure adequate ventilation.

summary: The air compressor room of the power plant provides a stable power source for power plant equipment by efficiently compressing and purifying air. Its operation directly affects the safety and economy of the power plant. Equipment selection, regular maintenance and safety management need to be combined to ensure reliable operation of the system.
