The report gives results of an examination of materials that might be used to line the firebox of a wood burning stove to produce more uniform and complete combustion. (Emissions from incomplete combustion in wood burning stoves are becoming an increasing environmental problem.) Although many materials were considered initially, 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 list of material properties of potentially useful refractories and a determination of the relative costs of installed refractory. The approach used in the study was to establish the conditions for a 'basic' stove, then to apply various candidate lining materials to the basic stove and analytically estimate the effect of the lining addition. Basic heat transfer calculations were used. The use of refractory materials permitted an increase in stove inner wall temperatures and an increased cool-down time for a stove. The study shows that refractory materials can aid in maintaining internal firebox temperatures above the ignition temperatures of common emissions. This would not be practical for an uninsulated stove. The study concludes that there is a need for actual tests to confirm results cited in the study.
