 ===== Smelt Spout Jacket Water Leak =====
-To be continued...
+If you have a **confirmed smelt spout cooling water leak** through the spout water jacket, it is necessary to shut off the cooling water to this spout. Once done, there is a decision to be made:
+  * **Continue Running**
+{{ boiler:smelt_system:plug-with-cord.jpg|Valmet's Plug}}
+If you can run the recovery boiler without this spout, then plug the spout according to the manufacturer's instructions and continue running the recovery boiler. However, be advised that each spout is rated for a specific heat loading. Thus you might have to reduce the load of the boiler in order not to overload the remaining spouts. Additionally, be aware that the heat loading on each spout might not be equal. However, there is a reason why the spout failed. And if this reason is operational, such as improper cooling temperatures (inlet or outlet), improper flows, or improper water treatment and thus deposits inside the spout jacket, then it is likely that with the current operations, other spouts may be close to failure as well.
+  * **Shutdown the Boiler**
+If you cannot continue running with the plugged spout, shut the boiler down orderly, burning out the bed, and replace the smelt spout.
