DCC unit: differential pressure issue between two devices
Thread Content
Hello, teacher: What is the operating range for the differential pressure control of these two devices, and how is it calculated?
Each device has certain differences, and generally, the operating specifications of the device are taken as the standard. The basis for differential pressure calculation is generally the driving force and resistance, in order to ensure proper fluidization and circulation of the catalyst in the device.
Currently, the differential pressure across the catalytic converters is not as stringent as expected; it can be determined through limit tests after loading the catalyst
The different forms determine the differential pressure range of the two devices; this value is specified in the design, and process control parameters are established through on-site adjustments for control purposes. The calculation is also relatively simple, based on the pressure balance between the two devices.
