Safe Operation of Acetylene Generator Systems
EIGA Doc. 237/21
This publication is intended to provide general guidelines for safe operation of acetylene generator systems. It is limited to acetylene generation systems using calcium carbide added to water, known as wet generation.
The scope includes the carbide supply from receipt at site to entry into the generator, the generation of acetylene to the pipe leaving the generator, the control of temperature via water supply into the generator, the control of level via the discharge of lime out of the generator and gasholders and buffers.
The scope does not include water utilities, lime handling after discharge from the generator, nor response to emergency or abnormal situations.
