Combustion air is supplied at the burner by a manually set damper. Damper settings are
calibrated at the factory and should not be adjusted unless Guspro Inc. has been consulted.
Gas flow modulation is accomplished through a High-Low fire actuator valve which is
cycled by the temperature controller to maintain set point.
The high/low fire valve train lines are equipped with adjustable valve which are set to
control the high fire. The low fire adjustment is factory set in the High-Low fire actuator and
should not be adjusted unless Guspro has been consulted.
These valves control gas flow and are set at initial start-up only.
2.3.2 Process Chamber Burner Configuration
The Process Chamber burner supplies heat input to raise the chamber to the operating set-
point temperature (normally between 550
o
F - 800
o
F).
The burner fires through the back wall into a firebox or combustion chamber. The
firebox is typically located under the cart.
The firebox fulfils the following functions:
• Prevents any direct contact between the flame and the material to be heat-cleaned. The
flame does not protrude outside this chamber.
• Heats the material to be heat-cleaned gradually and evenly to prevent thermal damage to
the components to be heat cleaned.
• Volatilizes the waste material gradually and at a controlled rate to avoid overloading of
the oxidizer chamber, which could result in incomplete combustion.
Gases and fumes resulting from the heat cleaning process flow through an inlet port from
the process chamber into the oxidizer chamber. When the process chamber reaches the set point,
the burner cycles to low fire.
2.3.3 Oxidizer Chamber Burner Configuration
The Oxidizer Chamber burner fires through the wall into a combustion chamber. The
oxidizer chamber is located on top of the process chamber.
Note: The oxidizer set-point temperature is dependent on regulations set forth by the local air
pollution district. This value typically varies between 1400
o
F and 1600
o
F over North
America.
