Can anyone tell me what the protruding rods mounted on the bottom of the engines of this 737 are? Something to do with de-icing perhaps?

They are "vortex dissipaters". They are part of the gravel runway kit that was an option on the B737-200 for operations at unimproved airports. They are used to help prevent debris from being ingested into the engines. Another part of the gravel kit visible on this plane is the gravel deflectors of the side of the fuselage near the nose wheel.

I guess that's the closest Boeing ever came to making a "bushjet"
