Abstract: An atmosphere handling system for use in a confined atmosphere is disclosed having an oxygen generator for generating oxygen from a stored release agent, an air conditioning system for cooling and re-circulating the air atmosphere, a desiccant module for filtering and removing moisture from the atmosphere and a power and operations system for powering and controlling the system.

Abstract: A burner has a nozzle formed of generally concentric inner and outer pieces. The inner piece defines a fuel conduit, and the outer piece defines an annular gas conduit which tapers down towards the outlet end of the nozzle. The inner piece has a rounded edge near the outlet end. The inner piece is longitudinally translatable, within a limited range of movement, relative to the outer piece, and can be locked into a desired position. The nozzle promotes efficient mixing of fuel and air (or oxygen) outside the burner. The stream of air creates a partial vacuum in the vicinity of the outlet end, serving to draw fuel out of the fuel conduit. Longitudinal adjustment of the inner piece allows the shape of the flame to be optimized. The burner can be used with virtually any fuel that can be provided in fluid form, whether solid, liquid or gas.

Abstract: A burner for combusting hydrocarbon fluids which may contain additional components as additives or contaminants and in the form of a gas, liquid or particulate matter, e.g. waste oil wherein the oil is atomized in a nozzle disposed in a housing defining a combustion chamber for receiving an oxidizing fluid, e.g. oxygen, so that atomized oil is mixed with the oxidizing fluid for combustion. Control of the length to diameter (L/D) ratio of the combustion chamber results in lower operating noise levels for the burner during combustion.
