Abstract
Abstract Apparatus and method for improving the efficiency of combustion in burners is disclosed. Air is circulated at a substantially constant controlled rate from a blower or compressor through a control valve to a release point beneath a catalyzing or catalyst-forming liquid, such as water, and is released beneath such surface in such a manner as to ensure the slow growth of relatively large bubbles. These bubbles break at the liquid surface, and the catalyst-laden air is then returned to the gas impelling means, in which it is mixed with more air and returned to the system. A portion of the catalyst-laden air is directed to the combustion device, e.g. the oil burner, at a point between the air impelling means and the bubble chamber, preferably at a point between the air impelling device and the first control valve.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
101 words
Apparatus for supplying catalyst to the blower of a liquid fuel combustion device, comprising gas impeller means for moving gas under pressure, a first conduit means connecting the output of the gas impeller means to the blower, second conduit means connected to said first conduit means at one end, and connected at the other end to a chamber means for contact of the gas carried by said second conduit means with a liquid, and third conduit means connected between said chamber means and said gas impeller means for feeding the gas treated in said chamber means into said gas impeller means.
Claim 2
Dependent Claim
101 words
Apparatus for supplying catalyst to the blower of a liquid fuel combustion device, comprising gas impeller means for moving gas under pressure, a first conduit means connecting the output of the gas impeller means to the blower, second conduit means connected to said first conduit means at one end, and connected at the other end to a chamber means for contact of the gas carried by said second conduit means with a liquid, and third conduit means connected between said chamber means and said gas impeller means for feeding the gas treated in said chamber means into said gas impeller means.
Claim 3
Dependent Claim
22 words
The apparatus of claim 1, wherein said second conduit means includes a valve for controlling the flow of the gas carried thereby.
Claim 4
Dependent Claim
22 words
The apparatus of claim 2, wherein the third conduit means includes a valve for controlling the flow of the gas carried thereby.
Claim 5
Dependent Claim
48 words
The apparatus of claim 2, wherein said second conduit means comprises a tube which extends below the level of liquid in said chamber, said tube having a discharge opening which is sized to provide bubbles of an average size of from about 0.4 to 1.5 inches in diameter.
Claim 6
Dependent Claim
25 words
The apparatus of claim 4, wherein the discharge opening is sized to provide bubbles of an average size of from about 0.6 to 0.85 inch.
Claim 7
Dependent Claim
39 words
The apparatus of claim 4 wherein the valve in said first conduit means is adjustable to provide a bubble formation rate at the discharge opening of from about two bubbles per second to about one bubble per 2 seconds.
Claim 8
Dependent Claim
34 words
The apparatus of claim 2, the capacity of said gas impelling device being sufficient to supply between about 0.02 and 0.2% by volume of the combustion air supplied to said liquid fuel combustion device.
Claim 9
Dependent Claim
15 words
The apparatus of claim 2, wherein said liquid fuel combustion device is an oil burner.
Claim 10
Dependent Claim
13 words
The apparatus of claim 2, wherein said gas impeller means comprises a blower.
Claim 11
Dependent Claim
13 words
The apparatus of claim 2 wherein said gas impeller means comprises a compressor.
Claim 12
Independent Claim
105 words
A method of improving combustion in an oil burner having a blower comprising feeding air through a gas impelling device, diverting part of the output air from said gas impelling device to a dip tube which extends beneath the surface of an aqueous liquid, bubbling said gas through said aqueous liquid in the form of bubbles having a diameter of about 0.6 to 0.85 inches at the rate of one bubble about ever 0.8 to 1.2 seconds, feeding said bubbled air to the gas impelling device, and feeding the non-diverted part of the output air from said gas impelling device into the oil burner blower.
Claim 13
Independent Claim
105 words
