Introduction

PRODUCT
DESCRIPTION
The ImmersoJet (IJ) is a nozzle-mix tube-firing burner that is
designed to fire at high velocities through small diameter
immersion tubes. The standard burner includes a packaged
blower, actuator control motor, integral butterfly valve, ratio
regulator, burner body, combustion chamber, nozzle (specific to
fuel used), rear cover, spark and flame rods, and gas orifice (also
specific to fuel used).
Figure 1.1
The ImmersoJet Burner
FEATURES
The combustion gases from the burner scrub the inner tube
surface and produce high heat transfer rates. This, in
combination with the high velocity flow through the smaller
diameter tubes allows for system efficiencies in excess of 80%.
The smaller ImmersoJet tubes also have smaller bends which
means less tank space is occupied by the tubes. With a
combustion chamber that is integral to the burner body, the
new version of the ImmersoJet can sit lower on the tank than
previous ImmersoJet models.
