Why is a low low pressure at the carbon scrubber outlet included in the interlock of the gasification furnace?
Thread Content
The outlet pressure of the carbon scrubber is very low, and this occurs during initialization and other processes. Why is that?
The prerequisite for performing this operation is that there is no pressure in the system, ensuring safety during the process and preventing accidents! It’s that simple………………
These are the original driving conditions; whether it’s Texaco or multi-nozzle, the main focus is on ensuring safety.
If there is pressure, when establishing the liquid level in the carbon scrubber tower, push water into the vaporizer to submerge the furnace bricks.
It is ensured that the vaporization furnace is in a stopped state during initialization; without this interlock, any accidental activation of the initialization button while the furnace is in operation could lead to serious accidents!
This is a safety interlock that ensures gasification feeding takes place under pressure-free conditions. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . :dizzy:
Reply to 5# wenyb-15: The gasifier that is currently in operation needs to be initialized; many other conditions are not met either, and it still cannot be initialized despite fulfilling this one condition.
Reply to 4# GiveItYourAll: The vaporizer and the carbon scrubber are connected with equal pressure
The pressure at the outlet of the carbon scrubber is low; this occurs during initialization and when many valves are controlled manually. Additionally, what is a suitable value for this low pressure at the outlet of the carbon scrubber? The temporary value for our unit is set at 0.4 MPa.
Reply to 9# 00shangjunfei: This is indeed a prerequisite for starting up the gasification furnace. The reason for setting this condition is to ensure safety when feeding material into the gasification furnace; if the pressure is high, it indicates that the raw material gas from the operating gasification furnace may be leaking into the furnace that is about to receive material, due to issues such as faulty valves or other problems. It seems to be GE’s safety design philosophy!
