Is that so? Even when ground fine and with enough oxygen? For local heating, I heard good things about the efficiency and cleanliness of wood pellet heaters.

Did you hear those things from either people trying to sell you a wood pellet burner, or people who've just spent a lot of money money on a wood pellet burner?

Personal anecdote- i bought a house with a wood pellet stove as a primary heat source. There was smoke damage to the paint everywhere.
