Method and apparatus of particulate removal from gasifier components
View Patent ↗Disclosed is a method of removing a particulate layer from a gasification system component including locating a shedding apparatus in operable communication with the gasification system component. A force is transmitted from the shedding apparatus into the gasification system component and the particulate layer is shed from the gasification system component as a result of the force. Further disclosed is a syngas cooler for a gasification system including a vessel and a plurality of thermal energy transfer platens located in the vessel. A shedding apparatus is in operable communication with the plurality of platens and is capable of shedding a particulate layer from the plurality of platens by transmitting a force to the plurality of platens. The apparatus includes a manifold disposed between the shedding apparatus and the plurality of platens and connected to the plurality of platens via one or more struts capable of distributing the force to the plurality of platens.
1. A syngas cooler for a gasification system comprising:
a vessel;
a plurality of thermal energy transfer platens disposed in the vessel;
a shedding apparatus in operable communication with the plurality of platens, the shedding apparatus capable of shedding a particulate layer from the plurality of platens by transmitting a force to the plurality of platens; and
a manifold disposed between the shedding apparatus and the plurality of platens and connected to the plurality of platens via one or more struts capable of distributing the force to the plurality of platens.
2. The syngas cooler of claim 1 wherein the manifold has a helical configuration.
3. The syngas cooler of claim 1 wherein the shedding apparatus comprises one of a mechanical crank, an electrical generator, a pneumatic generator or a fluid pulse in operable communication with the plurality of platens.
4. The syngas cooler of claim 3 wherein the shedding apparatus is disposed inside of a tubular support extending into the vessel.
5. The syngas cooler of claim 1 wherein the shedding apparatus comprises at least one shock tube.
6. The syngas cooler of claim 1 wherein the shedding apparatus comprises a plurality of sprayers capable of directing a high pressure flow toward the plurality of platens.
7. The syngas cooler of claim 6 wherein the plurality of sprayers are configured to direct one of a fluid flow or a solid projectile flow.
