The paper gives results of an examination of materials that might be used within the firebox of a wood-burning stove to produce more uniform and complete combustion. Although many materials were initially considered, refractory materials appear to possess the qualities desired relative to heat transfer, resistance to the firebox environment, availability, and cost. Further investigation of specific refractory materials has been carried out, resulting in a listing of material properties of potentially useful refractories and a determination of relative installed costs. Basic heat transfer calculations were used to determine the effects of the addition of refractory materials in the firebox. The use of refractory materials permitted an increase in stove inner wall temperatures and an increased cooldown time for a stove. The study showed that refractory materials could aid in maintaining internal firebox temperatures above the ignition temperatures of common emissions. This would not be a practical operational mode for an uninsulated stove. The study concluded that there is a need for actual testing to confirm the results cited in this study.
