My question was specifically about burning of deadwood for forest management, which apparently is available in huge quantities that need to be disposed of, but perhaps not consistently enough to e.g. use it to heat a city hall or gymnasium.

Wood pellets might be an answer. Some houses use pellet burning furnaces as an alternative to gas fuelled boilers etc. It is niche though.

There seemed to be a small wave of pellet furnace installations in Germany 5-10 years ago or so. From what I heard, pellets became so expensive in the meantime that new installations declined. Long story short: there is demand for wood pellets. The price is about 300€/(metric) ton right now.

Drax[0] in the UK have outfitted their old coal plants with wood pellets which are apparently sourced from the US. Questionable how much value there is in it given the carbon footprint of the shipping and the unclear stewardship of some of the wood.
