A Note on Density Change Patterns in Charred Wood


  • Bruce E. Cutter

Charcoal, apparent density, real density, hardwoods, softwoods


Apparent and real densities of seven species of wood and chars were measured. The chars had been prepared by heating in flowing nitrogen at rates of 1, 10 and 50 C/min. Generally, maximum rate of change was between 300 and 350 C. The decrease continued up to 600 C, the maximum charring temperature.
