Steam humidifier system

A steam humidifier system, for humidifying an air flow in a duct comprising:

• an elongate hollow manifold for receiving steam from a steam source;
• at least one steam dispersion tube extending from said manifold and communicating therewith for receiving steam therefrom, said dispersion tube being exposed to an air flow to be humidified;
• steam emitting nozzles on said dispersion tube and aimed to project steam into an air flow to be humidified;
• baffle members arranged in a first array spaced upstream in an air flow from said dispersion tube and means for fixing said first array with respect to said dispersion tube, said baffle members of said first array having spaced laterally therebetween and downstream therefrom said dispersion tube, such that air flow deflection and turbulence caused by the baffle members of the first array results in rapid and even disbursement of steam into the air flow leaving the system, said baffle members being baffle tubes of diameter and length similar to said dispersion tubes.

A humidifying system for humidifying air flow in a duct, the system comprising:

• a manifold for supplying steam;
• a dispersion tube extending from said manifold for insertion into an air flow to be humidified;
• steam emitting nozzles on said dispersion tube and aimed to project steam into an air flow to be humidified;
• an inner steam feed tube having one end connected to said manifold for receiving steam therefrom and extending axially in said dispersion tube from said manifold to an open free end adjacent a blind end of said steam dispersion tube, so that steam is injected into said steam dispersion tube at its end remote from said manifold, said steam feed tube being eccentrically located in said dispersion tube and circumferentially spaced from said nozzles, said nozzles being elongate and each extending from a point near the longitudinal central axis of said dispersion tube radially outward toward and opening through the peripheral wall of said dispersion tube, a series of said elongate nozzles being spaced side-by-side and occupying a plane extending radially and longitudinally of said dispersion tube, said steam supply tube lying to one side of said series of elongate nozzles and of said plane thereof and extending in skewed relation to said elongate nozzles, said elongate nozzles each extending transversely along one side of said steam supply tube, the opposite side of said steam supply tube snugly facing the interior surface of said dispersion tube to one side of said nozzles.

A humidifying system for humidifying air flow in a duct, the system comprising:

• a manifold for supplying steam;
• a dispersion tube extending from said manifold for insertion into an air flow to be humidified;
• steam emitting nozzles in said dispersion tube;
• an inner steam feed tube having one end connected to said manifold for receiving steam therefrom and extending axially in said dispersion tube from said manifold to an open free end adjacent a blind end of said steam dispersion tube, so that steam is injected into said steam dispersion tube at its end remote from said manifold, in which the inner steam feed tube is, at least through most of its length, laterally crushed substantially to a D-shaped cross section having an enlarged radius curved side arranged to lie close to the side of the corresponding steam dispersion tube diametrally opposed to the side carrying said nozzles, said substantially D-shaped cross section inner steam feed tube having a flattened face facing toward said nozzles and spaced therefrom by a clearance space for unimpeded steam flow into said nozzles.

A steam humidifier system, for humidifying an air flow in a duct comprising:

• an elongate hollow manifold for receiving steam from a steam source;
• a plurality of steam dispersion tubes extending in side-by-side, substantially parallel relation from said manifold and communicating therewith for receiving steam therefrom, said dispersion tubes being exposed to an air flow to be humidified;
• steam emitting nozzles on said dispersion tubes and aimed to project steam into an air flow to be humidified;
• baffle tubes arranged in a first array spaced upstream in an air flow from said dispersion tubes and means for fixing said first array with respect to said dispersion tubes, said baffle tubes of said first array having spaced laterally therebetween and downstream therefrom said dispersion tubes, such that air flow deflection and turbulence caused by the baffle tubes of the first array results in rapid and even disbursement of steam into the air flow leaving the system, said dispersion tubes being arranged in a second array, said dispersion tubes array being spaced downstream from said baffle tubes array, successive ones of said dispersion tubes being disposed evenly between and spaced downstream and laterally from the adjacent pair of baffle tubes such that a given said baffle tube and the adjacent pair of dispersion tubes are located at the three apices respectively of a triangle as seen from the tube ends, said dispersion tubes and baffle tubes together being the apices of a zig-zag pattern as seen from the tube ends.

• at least one steam dispersion tube extending from said manifold and communicating therewith for receiving steam therefrom, said steam dispersion tube being exposed to an air flow to be humidified;
• steam emitting nozzles in said dispersion tube and aimed to project steam into an air flow to be humidified;
• elongate substantially cylindrical baffle members of exterior cross-sectional shape and size generally similar to that of said dispersion tube, said baffle members being arranged in a first array spaced upstream in an air flow from said dispersion tube and means for fixing said first array with respect to said dispersion tube, said baffle members of said first array having spaced laterally therebetween and downstream therefrom said dispersion tube, such that air flow deflection turbulence caused by the baffle members of the first array results in rapid and even dispersement of steam into the air flow leaving the system.
