The device’s “factory air””
Thread Content
What is the purpose of the “factory air” in the device, and how is its amount determined? I would appreciate your guidance, expert.
The “plant air” for the device is divided into purified air (also known as instrument air) and unpurified air. Purified air (also known as instrument air) is primarily used as the power air for control valves. Unpurified air can be used for purging, loosening components, and protecting fuel oil from atomization.
Plant air, scientifically known as \"purified compressed air\" and also referred to as \"instrument air\", is air that has had impurities removed from it and then pressurized using an air compressor. It is primarily used to power control valves, and secondly for purging and displacing air during startup and shutdown processes. There are many user stations in the plant area; in addition, there is a small manual valve in front of each control valve, and that is usually the control valve for the instrument air. The person asking can go to the site to take a look.
Plant air includes instrument air and compressed air. The amount of instrument air is determined by the air required for the plant’s instruments plus a certain margin, while the compressed air amount is based on the normal production requirements plus the amount needed for purging during online maintenance
As mentioned upstairs, the air coming out of the air compressor is divided into instrument air and process air. Instrument air is used to supply air to instruments and valves, and it is required to be extremely clean, which is why filtering devices are needed. Process air is used for general purging.
