How to choose the air compressor for the boiler?

April 06, 2021

Recently, some factories consulted Dream Air Compressor through the network to reform the boiler room air compressor system to reduce equipment failure rates and improve boiler efficiency. The factory reports that there are problems with the air compressors currently in use:


1. The volume of the air compressor is too small, and the amount of stored gas is insufficient, which causes the air compressor to start too frequently. Every 3

Or start it every 5 minutes, and start it every 10 minutes or so. The direct result is empty.

The start-up circuit of the compressor often fails, which results in the shutdown of the air compressor.

Corresponding to a boiler, the boiler could not be started at the same time.


2. The vibration of the air compressor is too large, and its starting circuit is installed on the body. The excessive vibration causes the screws

Loose, the starter box falls off, and the circuit is short-circuited. The AC contactor inside the starter box fell off due to the vibration of the air compressor, which may burn the motor.


3. The air supply pipeline of the air compressor is made of PVC, and the middle connection of the pipe is glued. Because of the boiler room,

The internal temperature is high, and the joint often falls off and the pipe punctures during the pressure process.


So what is the direct connection between the air compressor and the boiler?


1. In the process of using the boiler, compressed air from an air compressor is required to provide a source of power for the boiler.


2. Blow ash with compressed air and blow pipe during maintenance.


3. Control systems such as boiler instruments and pneumatic valves are generally oil-free air compressors. Pneumatic valve: A pneumatic valve is a valve driven by compressed air. When the pneumatic valve is purchased, only the specifications, categories, and working pressure are met to meet the procurement requirements. It can be used to control various types of fluids such as air, water, steam, various corrosive media, muds, oils, liquid metals and radioactive media. flow.


4. Boiler air compressor waste heat recovery.
