Barber Solarflo Burner Assemblies

Exclusive Barber Jet Features

Barber Jets produce up to 432,000 BTU per square foot of burner area. They produce up to 300,000 BTU per cubic foot of burner area. They develop up to 1900°F. temperature. They require no air adjustment. Over 50 sizes accommodate applications needing from 2500 to 8,000,000 BTU/hr.

General Application Procedures

Though each unit that uses jet burners has some variables, there are certain constants that should be used on all jet burner applications.

1. All air must be introduced under the burners. Air introduced on the same level as the burners will cause a turbulent flame and poor combustion efficiency. Also jet burners need a generous supply of air since the air introduced is for primary as well as secondary air.

2. The use of a baffle to direct all the air underneath the burner proper is also very important. No air should be allowed to go around the burner since this will cause a turbulent flame and cause poor combustion efficiency.

3. The minimum distance from the tips of the jets to the bottom of the heated medium should be approximately as follows depending on the BTU input per jet:

Jet Type

Distance

BTU Input

Impinged Jets

5" (125 mm)

 2500 BTU per jet

9" (225 mm)

5000 BTU per jet

13 “ (325 mm)

7500 BTU per jet

17" (425 mm)

10,000 BTU per jet

Slotted Cap Jets

3" (75 mm)

2500 BTU per jet

4 “ (100 mm)

5000 BTU per jet

5 “ (125 mm)

7500 BTU per jet

We say “approximately” since there is some variation depending upon the application. These distances, however, prove generally to give the best overall efficiency in most applications.

4. Generally the use of a flue is not required on small input applications, however, on larger applications where flue connections are required the outlet must be above the top most part of the combustion area. In fact the higher the flue is located, the better. Also, where relief ports can be provided above the combustion zone level, the use of a flue is generally not required.

5. Combinations of burner units are often required to attain larger inputs than individual units develop.

Ordering Instructions

1. Always specify type gas and gas pressure available.

2. Odd numbered burners (e.g. Z-21) have bottom pipe openings, even numbered burners (e.g. Z-20) have side pipe openings, except as otherwise designated.

3. In cases where burner has more than one size pipe opening, please specify size desired.

4. Burners are normally shipped with jets drilled to produce the median BTU i
