Water system for integrated commissioning of the gasifier
Thread Content
Is the water system used for the combined commissioning of the gasifier the same as that used in normal production? Is it necessary to apply a certain pressure to the gasifier when setting up the water system?
Pressurization is generally not required inside the vaporization furnace; the purpose of water circulation is mainly to assess the performance of the power equipment, and this goal can be achieved with pump pressure alone. This post was last edited by wbp on 2009-3-21 20:09]
The linkage should include pressure-water linkage. For example, some valve adjustments must be carried out under high pressure differences. A simulated test is one that attempts to replicate the conditions of actual operation as closely as possible.
The combined test run differs from normal operations, mainly in terms of the temperature of the water system. However, the integrated testing of water systems must be carried out at a certain pressure to function (note: this pressure is not necessarily the same as that used in actual production).

The combined testing of the vaporization furnace mainly includes water distribution tests and water pressure tests. The water distribution test focuses on the water in the quenching ring of the quenching chamber, aiming to check whether the water is distributed evenly. The water in this quenching ring forms a water film along the sides of the downcomer to protect it from being damaged; uneven water distribution can easily lead to damage to the downcomer. The hydrostatic test is primarily used to evaluate the performance and pressure of the high-pressure slurry pump, ensuring that no issues arise with it during operation. There are other linked water experiments, namely the sump flushing water and the quench chamber water level.
The water-conveyance system should be pressurized in order to test the gasification and ash-water valves
May I ask how to determine the water distribution in the quench ring during the coupled testing mentioned on the 6th floor? Thank you for everyone's answers
The joint commissioning test involves checking the valve operations of the vaporization furnace under normal operating conditions, including the conditions of the water and gas systems, as well as the pressure within the vaporization furnace.
Since a ladder must be set up inside the vaporization furnace every time the refractory bricks or cryogenic rings there are inspected, observing the distribution of the cryogenic water requires entering through the manhole in the furnace’s quenching chamber, going up along the downcomer, and contacting the on-site operators to turn on the cryogenic water. This allows one to check how the water is distributed across the four cryogenic rings, to determine whether there is any deviation in its flow or leakage at the flange connections, as each cryogenic ring consists of 24 holes with a diameter of 12 mm. It is evenly distributed around the downcomer to protect it from being damaged by water gas
In water intertransport, both pressure and temperature need to be increased, with the aim of ensuring the proper functioning of instruments and valves under normal operating conditions； Performance of moving equipment ； Leakage status of the entire water system ； Distribution of each cooling water pipeline ； The connection flanges must also be heat tightened. I don’t know what kind of furnace the original poster is referring to; a SHELL furnace needs to be raised to over 200 degrees.
It applies only to the Texaco gasifier; I’m sorry for not making that clear.
