I must tell you that when I do cook on my woodstove we do on top of stove an old fancy grate about 9" x 20" that is raised. We also placed a 9"circle cast iron disc that has holes in it. This keeps the pots a little above the surface. Don't remember where these came from but my husband is a pack rat! and he has lived in our house for 70 years and his parents owned an old farm house where they "never threw anything out.
