Can you burn willow in wood stove?

Drift wood can be used in a wood burning stove. It is not as efficient as other aged wood but it will burn. Drift wood is often collected on beaches to have bon-fires.

Any wood that has been in the ocean will destroy your stove in a matter of months.

I sell wood stoves. A fellow brought in his stainless steel baffle from a stove that he purchase from us less than 6 months earlier. He had been burning wood that had been in the ocean. I could literally crumble it in my hand.
