Air-flow-controlling rear housing member
a rear housing and air flow control technology, applied in the field of housing members, can solve the problems of significant improvement of the end, inefficiency of the burner type, and the efficiency of the majority of the prior art burner, and achieve the effect of only about 60% to 70% efficiency

Benefits of technology
[0016]It is an object of the present invention to provide a air-flow-controlling rear housing member for use in a burner, wherein the air-flow-controlling rear housing member causes the burner to burn fuel very efficiently.
[0003]Burners that use gaseous fuel or liquid fuel are used in many applications including boilers, line heaters, furnaces, other gas fired appliances, and in many others. Basically, these burners introduce a gaseous fuel or liquid fuel into a stream of air or oxygen. If liquid fuel is used, it must be vapourized or atomized first. The resulting flow of fuel and air or oxygen is ignited and exits the nozzle of the burner either as a visible flame or as a stream of an extremely hot gaseous mixture.
[0018]It is a further object of the present invention to provide a air-flow-controlling rear housing member for use in a burner, wherein the air-flow-controlling rear housing member and burner can be used with various types of gaseous and liquid fuels.

Problems solved by technology
In present world markets, operational costs and environmental concerns, such as reduction or elimination of emissions, are typically two of the most significant issues, if not the most significant issues faced by most businesses.
Interestingly, it is readily apparent in the prior art that the possible improvements that could be made to these various types of devices utilizing burners to produce heat, would not lead to a significantly improved end result.
It is also readily apparent that, without exception, the fundamental problem in these various types of devices was that of burner inefficiency.
Most prior art burners are only about 60% to 70% efficient.
Inefficient combustion of fuel was the main problem inherent with all of these devices.
Moreover, this problem of inefficiency of combustion is the major cause of the two above mentioned significant costs in business, namely operational costs and environmental concerns.
There is no sense in improving boiler technology, line heater technology, furnace technology, and so on, if the burners used in them are prohibitively inefficient.
There are, however, problems associated with such recirculation of the exhaust gases.
The most significant problem is that the recirculation of exhaust gases substantially increases the energy required for passing the mixture flow of combustion air and added exhaust gas through the system.
Obviously, this is an attempt at a solution that is less than acceptable in terms of efficiency, and therefore cost.
The effectiveness of this technique depends on many factors, and typically it is more difficult to return a substantial portion of combustion products back to the burner if this technique is used, thus making it difficult to employ in many situations.
It is clear that recirculating exhaust gases in order to improve emissions is not a viable solution to improving the design of burner systems.

Embodiment Construction
[0031]Reference will now be made to FIGS. 1 through 8, which show a preferred embodiment of the air-flow-controlling rear housing according to the present invention, as indicated by general reference numeral 30. It should be understood that although for some shapes of burners the determination of front end back and the back end might be somewhat arbitrary, the front end is generally defined as the flame is produced, and the back end is defined as the area where the air and the fuel have their inputs, and where the mixing of the air and the fuel begins.

An oxygen flow controlling rear housing member for use in a burner comprises a main body portion with a first oxygen inlet. An annular oxygen gathering chamber is in fluid communication with the first oxygen inlet. An annular wall divides the annular oxygen gathering chamber and an annular oxygen-flow mixing chamber. A first oxygen flow passageway extends between the annular oxygen gathering chamber and the annular oxygen-flow mixing chamber, and has a first height that is a portion of the height of the annular wall. A second oxygen flow passageway extends between the annular oxygen gathering chamber and the annular oxygen-flow mixing chamber, and has a second height that is a portion of the height of the annular wall. The height of the first oxygen flow passageway is greater than the height of the second oxygen flow passageway.
