injection in case the oven operational temperatures exceed set parameters.
The process burner is controlled by a programmable digital temperature controller, which
can store up to four programs patterns with 16 steps of ramp and soaks. The process burner uses
of a High/Low gas valve which will cycle between high and low fire to maintain set point. This
enables heat cleaning temperature control and fuel efficiency.
An independent digital temperature controller controls the oxidizer system. The oxidizer
temperature controller senses the stack temperature and controls oxidizer temperatures through
the use of a High/Low gas valve control system.
The use of a High/Low gas valve allows for a fast response oxidizer system (FRS). This
system gets the oxidizer to set point temperature quickly and then cycles to low fire to maintain
set point.
The oxidizer chamber also includes an excess airport for excess air combustion of
combustibles. The oxidizer chamber is designed to operate at a set-point temperature of between
1400
o
F (760
0
C) to 1600
o
F (870
0
C).
Note: The oxidizer set-point temperature is dependent on regulations set forth by the local air
pollution control authority. This value typically varies between 1400
o
F and 1600
o
F
over North America.
The oxidizer chamber is designed for a total residence time of 0.50 to 1.00 second
through the refractory lined mixing chamber and stack volume up to the thermocouple port.
Guspro ovens are equipped with a manual reset Excess Temperature Controller (ETC-S)
located in the panel. The ETC-S is used for safety shutdown if the flue gas temperature exceeds
a pre-set limit (1850
o
F).
Operating and safety controls required by most provinces, states and local codes are
standard equipment. Special requirements such as Factory Mutual (FM) standards and Industrial
Risk Insurers (IRI) standards are available at extra cost where required by the purchaser or the
insurance underwriter.
1.6 Installation
The Guspro heat-cleaning oven is completely piped, wired and tested at the factory to
reduce installation costs to a minimum.
