Abstract
Abstract A gas generator is capable of being stored in a stable form for long periods of time without deteriorating in quality. The gas generator provides a substantial amount of gases, and particularly oxygen, carbon monoxide or carbon dioxide without producing any harmful or hazardous chemicals. The gas generator includes in some embodiments a minimum of fuel so that a maximum amount of oxygen in the generator is capable of being liberated. The oxygen is liberated by the combustion of a fuel at localized positions in a refractory binder, which has the property of preventing the salt residue from becoming molten and the oxidizer from flowing and thereby preventing the combustion from becoming extinguished. The gas generator includes a suitable clay as a binder, coke as the fuel and a chlorate such as sodium chlorate or potassium chlorate as the oxidizer. The binder is included in the generator in the range of approximately 7% to 15% by weight; the fuel is included in the generator to an amount of approximately 25% by weight, depending upon the use to be made of the generator; and the remainder constitutes the oxidizer.
