Will increasing the compressor inlet pressure increase the work done by the compressor? What’s the principle?
Increase inlet pressure and reduce energy consumption
To increase the inlet pressure of the compressor, it is necessary to take into account the capacity of the outlet; a higher inlet pressure will result in a higher outlet pressure as well, and if the outlet cannot handle this pressure, it may lead to accidents
To increase the inlet pressure of the compressor, it is necessary to take into account the requirements at the outlet; if process parameters such as outlet pressure and flow rate remain unchanged, what becomes complex is the mechanical and operational adjustments required for the compressor unit.
The compressor outlet pressure depends on the back pressure in the pipeline; if the flow rate, temperature, and back pressure remain unchanged, an increase in inlet pressure leads to a decrease in the pressure ratio, as well as a reduction in power output
As the inlet pressure increases, the pressure ratio decreases, and the power also decreases.
Increase the inlet pressure while keeping the rotational speed constant? Is there more steam available for the turbines? What’s going on?
It is not specified whether it is a reciprocating or centrifugal compressor. In the case of a reciprocating compressor, an increase in inlet pressure leads to an increase in air intake and thus higher power consumption, while a decrease in pressure ratio results in lower power consumption; it is necessary to determine which of these two changes occurs more rapidly
Mechanical methods for increasing the inlet pressure cannot increase it indefinitely, after all, the inlet valve has a specific pressure range.
There must be changes in flow rate, temperature, or back pressure; take a closer look
