Abstract
According to various embodiments, a system includes a gasifier that includes a shell made of a first material exposed to a gasification region inside the gasifier and a patterned anode layer coupled to the shell inside the gasifier. The patterned anode layer is made of a second material, and the patterned anode layer is configured to protect the shell from corrosion by condensing hot gas in the gasification region.
Claims20
A system, comprising:
- a gasifier comprising a shell made of a first material exposed to a gasification region inside the gasifier;
- and
- a patterned anode layer coupled to the shell inside the gasifier, wherein the patterned anode layer is made of a second material, and the patterned anode layer is configured to protect the shell from corrosion by condensing hot gas in the gasification region.
A system, comprising:
- a gasification component comprising a first material exposed to a flow of a condensing corrosive gas;
- and
- an anode layer comprising a second material coupled to the first material, wherein the anode layer is configured to protect the first material from corrosion by the condensing corrosive gas.
A system, comprising:
- an active anode layer configured to protect a surface of a gasification component from corrosion by a gasification product gas;
- a reference electrode in contact with the gasification product gas;
- and
- a controller configured to adjust a current to the active anode layer in response to feedback from the reference electrode.
