DESCRIPTION
1
Eclipse AH-MA v2.10 Air Heat burners produce a uniform, odorless,
and smokeless flame ideal for heating fresh air in mak e-up and process
air heating applications. The AH-MA design provides stable operation
over a wide range of velocities, inputs, and fuels.
AH-MA v2.10 burners are line type burners constructed of cast
iron or aluminum burner bodies and diverging stainless steel air
wings. The burner bodies supply fuel to the center of the air wings to
control the air and fuel mixture inside the burner and to optimize
emissions and efficiency. Completely corrosion resistant design
options are a vailable using aluminum burner bodies or elec troless
nickel plated cast iron burner bodies.
The AH-MA v2.10 Air Heat burner is assembled from straight
sections, tees, and crosses to produce nearly any configuration
required. Large burners can be built as a combination of staged,
individually controlled sections to increase turndown.

applied, installed adjusted, controlled, or
maintained.
Do not bypass any safety feature.
You can cause fires and explosions.
Never try to light the burner if the burner shows
signs of damage or malfunctioning.
Warning:
The burner and duct sections are likely to have
HOT surfaces. Always wear protective clothing
when approaching the burner.
Note:
This manual gives information for the use of these burners
for their specific limited design purpose. Do not deviate from
any instructions limits in this manual without written advice
from Eclipse Combustion.
Note:
