Abstract
A solid moldable fuel composition comprising an acetal resin containing from about 0.5 to about 1.5% by weight fumed silica to increase the flame temperature at which the acetal resin will burn. The composition may further include an antimony oxide flame retardant in an amount of from about 0.05 to about 0.8% by weight to regulate the flame temperature of the composition between about 1500.degree. and 2500.degree. F. and increase the combustion time of the composition. Further ingredients such as a cellulose ester and alkali or alkaline earth metal carbonate may be incorporated to facilitate ignition of the composition and increase its combustion time.
