FIRING BOILERS WITH COMBUSTION
CHAMBERS
The Models 701CRD and 801CRD operate with superior efficiency
and cleanliness in properly designed refractory-type combustion
chambers. Very wide tolerance to burner adjustments and other
variables is found when these chambers are used.
Tables 1 and 2, show the recommended minimum inside
dimensions for refractory brick, refractory pre-cast and

FIRING BOILERS WITHOUT REFRACTORY CHAMBERS
Depending upon the geometry of the combustion space some units perform better than others without refractory. When the
back wall of the unit coincides approximately with the end ofthe flame, a target of refractory material is usually required.
Tables 3 and 4 show MINIMUM dimensions required for good combustion. They may be exceeded without much effect.

pre-formed refractory fiber chambers. Due to their quick
warm-up properties, the light, insulating-type materials
are slightly preferable although these burners show less
dependence upon refractory temperature than previous
models. Refractory materials in boilers and furnaces should
be capable of withstanding 2600°F (1427°C) or higher.
The notes accompanying Table 1 and 2 provide further
details relative to variations in dimensions and geometry.
