Compressors, centrifugal problems causes

Fuel systems can cause many problems, and fuel nozzles are especially susceptible to trouble. A gaseous fuel system consists of fuel filters, regulators, and gauges. Fuel is injected at a pressure of about 60 psi (4 Bar) above the compressor discharge pressure for which a gas compression system is needed. Knockout drums or centrifuges are recommended, and should be implemented to ensure no liquid carry-overs in the gaseous system. 

One way to decrease your reliability and cause problems is to not men tion fouling potential in centrifugal compressor specifications if proce.s.s experience exists. The experience may exist but not be recognized... 

Therefore, negative pressure was decreased to reduce tramp air. Also, the operational reciprocating compressor was replaced by a centrifugal rotary screw type compressor. Further, ash build up on the boiler superheater tubes was a problem, impeding heat transfer to cool down the flue gas. This problem was resolved by using acoustics to cause the ash to fall off the superheater and economizer tubes. This allowed lower fuel consumption, resulting in decreased NOx emissions.1... 

Large centrifugal compressors have proven to be highly reliable in evaporator systems. Most operational problems have been caused by improper matching of compressor and evaporator and excessive entrainment. Several actions are recommended to maximize compressor reliability ... 

This formula will permit one to differentiate between compressor deficiencies and losses in refrigeration from evaporator or condenser problems. A reduction in horsepower for a steam-driven centrifugal compressor is caused by one of four factors ...
