Driving equipment for catalytic air compressors
Thread Content
Is the driving device for a catalytic air compressor a motor or a turbine?
If you have excess steam (the efficiency needs to be calculated based on parameters such as the temperature, pressure, and flow rate of the steam at your site), it is recommended to use a turbine.
Some have motors, some have steam turbines; most use steam turbines
Currently, as more such units are put into operation, back-pressure steam turbines are being used, which results in a shortage of 3.5-grade steam and an excess of 1.0-grade steam; in summer, steam is released to the atmosphere in many places
Since they are all back-pressure turbines that result in a shortage of medium-pressure steam and an excess of low-pressure steam, why not consider condensing turbines? Although such units may consume slightly more energy, it would still be beneficial for the entire plant! Solved the problem of insufficient medium-pressure steam and excess low-pressure steam!
The compressors in our old factory area are all motor-driven, while those in the new factory area are of the 3.5 backpressure type. The circulating water tank uses a condensing type system with a pressure of 1.0 MPA. Under normal operating conditions, low-load operation of the thermal electric boilers is sufficient for our low- and medium-pressure systems
Which one consumes more energy, the condensing type or the back-pressure type?
Condensing systems consume a lot of energy and involve phase changes!
Depending on the conditions of each facility, different types of drives are used; some units employ condensing types to balance the steam supply, while others use back-pressure types. In companies where there is a shortage of steam, electric motors are used instead
