Problems with the water system of the gasifier

1. The multi-nozzle gasification furnace should be a water-coal slurry furnace, with two units in operation and one as a backup, to provide time for replacing burners and performing equipment maintenance. However, based on current operating experience, it is better to have two units in operation and one as a backup; of course, this should be determined according to the process requirements. Pump equipment in the system is prone to malfunctions; the configuration of one in operation and one as backup, or two in operation and one as backup, is also intended for maintenance purposes. To share pumps between the two systems, it is necessary to fully connect the systems, which results in higher costs for valves and pipes; the savings resulting from using the same pumps are not very significant in comparison ； Moreover, if there is a problem with the shared system, it will prevent both systems from functioning, which is not worth it. 2. From the perspective of system redundancy and critical pumps (powered by emergency power), generally, the two pumps associated with a single furnace should be powered by two separate busbars, so that in the event of a power failure, the backup pumps can start automatically, thereby ensuring system safety. There will be some difficulties in sharing the power supply for the pumps of the two sets of furnaces.

I had seen other installations where two systems shared three pumps, and I noticed that the water supply systems for the vaporization furnace each used separate pumps; that’s why I asked this question. I hadn’t thought of those points you mentioned before: handshake
