WATER INJECTION METHOD TO CENTRIFUGAL COMPRESSOR AND CENTRIFUGAL COMPRESSOR WITH WATER INJECTION FUNCTION

摘要

PROBLEM TO BE SOLVED: To atomize spray using energy of an airflow without using two fluid nozzle in water injection (an intake-air cooling, an inter-cooling, etc.), to a centrifugal compressor. SOLUTION: Water is injected with a diffuser 22 of the centrifugal compressor. In that case, the position of the water injection hole 32 is determined in consideration of distribution of gas flow velocity in the diffuser 22, etc.
