In the power plant, major in thermal control, boiler operation and maintenance, turbine operation and maintenance, chemical water treatment, electrical engineering and mechanical maintenance, etc. Air compressors are used, and their application runs through the power supply, equipment control, process operation, maintenance and other core links of the power plant. The following is a specific analysis:
1. Thermal control specialty
- core Applications: The air compressor provides power source for thermal instruments and pneumatic actuators (such as pneumatic valves and regulating valves) to ensure the stable operation of the automatic control system of boilers, steam turbines and other main equipment.
- Typical Scene:
- in the boiler combustion control system, the pneumatic control valve adjusts the fuel and air ratio through compressed air to achieve combustion optimization.
- In the steam turbine speed control system, compressed air drives the governor to maintain the stability of the unit speed.
- Equipment Requirements: to be equipped oil-free air compressor to avoid oil pollution of instrument components and ensure control accuracy.
2. Boiler operation and maintenance discipline
- core Applications air compressor is used for boiler soot blowing system, ash removal system and maintenance operation.
- Typical Scene:
- soot blowing system: High-pressure air removes ash deposits on boiler heating surfaces (such as superheaters and economizers) to improve thermal efficiency.
- Ash removal system: Conveying fly ash to ash silo by compressed air to prevent ash hopper from blocking.
- Maintenance operation pneumatic tools (such as pneumatic wrenches and sandblasting machines) rely on compressed air drive to improve maintenance efficiency.
- Equipment Requirements: to be equipped large flow, high pressure air compressor to meet the demand of continuous purging.
3. Steam turbine operation and maintenance discipline
- core Applications: The air compressor provides power for the turbine speed control system, lubricating oil system and sealing system.
- Typical Scene:
- speed regulating system: Compressed air drives the governor oil pressure device to control the steam turbine intake.
- Sealing system: The gas seal device uses compressed air to prevent steam leakage and improve unit efficiency.
- Equipment Requirements: to be equipped air compressor for stable air supply, To ensure that the speed control system responds sensitively.
4. Chemical water treatment specialty
- core Applications: The air compressor provides backwashing air source for water treatment equipment (such as filters and reverse osmosis devices) and drives pneumatic valves.
- Typical Scene:
- reverse osmosis system: Compressed air backwashes the membrane module to extend the service life of the membrane.
- Dosing system pneumatic diaphragm pumps rely on compressed air to deliver chemicals.
- Equipment Requirements: to be equipped oil-free, dry compressed air prevent chemical contamination.
5. Electrical Engineering
- core Applications: The air compressor provides operating air source for electrical switches (such as air circuit breakers and isolating switches).
- Typical Scene:
- high voltage switch cabinet: Compressed air drive circuit breaker opening and closing, to achieve rapid cut-off of fault current.
- Equipment Requirements: to be equipped high pressure, high reliability air compressor ensure electrical system safety.
6. Mechanical maintenance specialty
- core Applications: Air compressor provides power for pneumatic tools (such as pneumatic wrench and sandblasting machine) for equipment overhaul and maintenance.
- Typical Scene:
- equipment maintenance: Pneumatic tools remove bolts and clean the surface of equipment to improve maintenance efficiency.
- Equipment Requirements: to be equipped portable, mobile air compressor adapt to the needs of field operations.
