How are the pressure levels for nitrogen displacement specified?
Thread Content
Could some expert please tell me why medium-pressure nitrogen is used instead of low-pressure nitrogen for the gasification furnace’s quench chamber and combustion chamber?
The pressure and flow rate of low-pressure nitrogen can also meet the requirements for displacement, but if pressure buildup displacement is considered, medium-pressure nitrogen may be faster.
Who says that medium-pressure nitrogen must be used for the replacement of the quench chamber and combustion chamber in a gasification furnace? Low-pressure nitrogen can be used just as well.
Some manufacturers have switched to low-pressure nitrogen, but medium-pressure nitrogen still provides a faster replacement rate
