Abstract
A high flow sodium chlorate oxygen generator assembly (10) of a relatively small diameter. The generator assembly includes a chlorate candle (12) mounted within a containment vessel (14, 16, 18), the chlorate candle being provided with a deep conical recess (54) which is thinly coated with a rapidly combustible material (56). Ignition of the rapidly combustible material is achieved by extending a hollow ceramic tube (58) from a primer (38) located at one end of the containment vessel, the hollow tube directing the flame from the primer, when ignited, towards the center of the deepest part of the conical depression. The above construction provides a high surface area for burning, and also intensifies the heat flux within the chlorate candle thereby substantially increasing the rate of oxygen output over known chlorate candles of comparable diameters.
