 COMBUSTION
CHAMBER AND HEAT EXCHANGER(S)
The flame produced by the burner heats the combustion chamber
and heat exchanger(s) and causes them to reach temperatures in
the range of 200° to 1000° F. Infra-red generated is in
the range of 300 to 6500 BTUH/ft2 thus the term low
intensity.
The combustion chamber is made of 14 gauge (0.083") aluminized
steel or 12 gauge (0.109') black steel. The heat exchanger(s)
is made of 12 gauge black steel or 14 gauge aluminized steel.
Both provide 1.052 per square feet of radiant surface per linear
foot. The last heat exchanger in each system incorporates a spiral
turbulator for increased efficiencies.
The 10, and 5' sections are joined by standard compression coupling
tube clamps. These clamps are made of two layers of 18 gauge (0.052")
aluminized steel. The inner sleeve has precision meshing teeth
for even draw and pressure. Each tube clamp is closed with three
5/8", 651b. torque, zinc plated carriage bolts. A #5 malleable
iron turnbuckle-5/8" eye to eye is also standard.
