Hybridburners.com, proud to be a supplier of burners to NASA
This web site shows the results of my work with two other metal workers, Ron
Reil and Mike Porter. Our work has resulted in the design and creation
of a very special family of high efficiency, hybrid, propane gas burners which you can explore on the products page. Although
the description of these burners indicates a particular intended use
for each burner, they can be used for any application which requires a high
intensity burner of a given size and output. For BTU outputs of the more popular burners in the product family see the BTU charts page. Thank you.
These burners are the
result of many months of intense design and testing, in order to produce
the maximum BTU output, temperature, efficiency, and economy, possible in
a burner of this type. These are "naturally aspirated," jet
ejector burners, meaning they do not require any external blowers or
compressed air supply. They generate approximately a 28:1 induction ratio by volume,
as compared with an 18:1 or 20:1 ratio for other burner types, such as the
"Reil or EZ burners." They are self contained, which makes their use
simple and clean, as compared to old fashioned inefficient plumbing systems
where gas and compressed air are fed into a mixer tube, and the resultant
gas mixture fed into a forge or furnace chamber where the burn takes place.
This commonly used method has several drawbacks. First it is complicated
to set up and operate, and needs an external power source. The operator has
to adjust the gas flow and air input carefully to achieve the best possible
mixture in order to achieve the slightly reducing atmosphere needed in the
chamber. This is not very effective due to the presence of free oxygen in
any "chamber burn" system. Also, the injection of cold gases into the forge
chamber results in a decrease in the chamber temperature.
A superior system
utilizes a nozzle initiated burn, and completes the burn within a few inches
of the mouth of the burner. This prevents the introduction of free oxygen
into the forge or furnace, which can unite with the hot metal and cause scaling
of the iron, or degradation of any metal in a liquid state. Free oxygen will
also decrease the life of the chamber, and any crucibles or tooling exposed
to it at high temperatures. The burners I offer here provide a "win-win"
solution to these problems. Only completely burned gases are circulating
around inside the forge or furnace chamber, resulting in less scaling of
the iron, less degradation of equipment, and an increase in chamber temperatures.
This also increases the fuel efficiency of the system, and results in better
economy of operation, more bang for the buck, an important consideration
considering the high fuel prices presently found in most locations.
Another benefit of this burner design is the highly efficient choke system
it utilizes. The burner is designed to operate at a slightly oxidizing mixture
across its entire operating range. The choke is intended to allow instant and
very easy adjustment of the flame to a neutral or reducing mixture as needed
in your particular application. How do you know when you have the right gas/air
setting you ask? You only have to look at the flame
characteristics image on Ron's Forge and Burner Design Page to be able to
instantly adjust your burner to its optimum setting. The color change
from green to blue is the indicator that you use to judge your setting.
The burners I offer are not made of off the shelf plumbing parts screwed together to produce a
cheap, but less effective burner. The tuned burner intake chamber is turned and milled.
Solid 1018 CR round stock is used for end cap; drilled & tapped for the gas jet. The jet alignment is axially
true to the burner bore, and a long orifice jet is used to create an almost perfectly collimated, high velocity, gas injection stream, resulting in a tremendous Venturi suction being
created. These are also "hybrid" burners. They employ the air intake and mixing chamber
of a larger burner, and combine that with a small burner tube, resulting in a "super burner"
of sorts. It will fit into a much smaller burner mounting, but provide the output of a much
larger burner. Because of the tremendous Venturi vacuum that is created, these burners generate
a significantly greater injection pressure. This allows the burner to be used as a carburetor
to feed a supply manifold for multi nozzle injection, while having the actual burner remote to
the forge or furnace. The increased injection pressure also makes this burner design less
susceptible to "back-pressure" problems in the forge or furnace, which can result lower chamber
temperatures, and the dangerous production of CO.
Although these burners
will cost you more than building one out of off the shelf plumbing parts,
you are getting a LOT more burner for your money. I am able to keep the prices
of these burners relatively low through the use of jigs and mass production
techniques. Each burner design is the result of thousands of dollars
invested in building and testing many prototypes in order to refine the design
to the absolute peak of efficiency and output. When you buy one of these
burners you can be assured you are getting the highest quality and most efficient
burner currently available today to the private shop or small business.
