摘要:
The increase of temperature in heat sensitive devices during heat generating conditions is prevented through the absorption of heat, by providing a carbohydrate endotherm in an amount sufficient to effect the required heat absorption. The carbohydrate endotherm operates in an environment substantially devoid of potential oxidizing reactants. A scavenger may be employed in combination with the carbohydrate endotherm to remove or neutralize potential oxidizing reactants. Alternatively (or in addition), a fluoro-inert material may be employed in combination with the carbohydrate endotherm to effect a desired non-oxidizing environment. The carbohydrate endotherm may be used to provide thermal control and/or thermal protection in a variety of applications and environments. The carbohydrate endotherm may also be employed in combination with previously disclosed endotherm materials to achieve synergistic benefits therewith.

摘要:
A forced air heater is described having a plurality of combustion zones and an interceding cooling zone with active cooling devices. Catalytic oxidation may be implemented in the combustion zone whereby efficiency is increased by cooling the combustion products and outflow to more efficient temperatures. The catalytic bed of the combustion zone may be placed downstream of the cooling and primary combustion zone to remove noxious combustion by-products and an afterburner may also be included.
