J. TEMPERATURE SENSOR (COMPUTER CONTROLS)
The temperature sensor used, is a transducer that converts heat into microamps that the computer board
then uses to calculate the temperature.
K. GAS BURNER
Gas dryers are equipped with a gas burner
located behind the control door. The gas
burner assembly consists of the burner
tubes, orifices (the orifices have a hole in
them to allow gas to flow through. The
hole size varies with different elevations,
and different Btu), gas valve (which can
be set up for natural gas or liquid propane
[L.P.] gas), spark ignitor/flame-probe
assembly, sail switch, and hi-limit
thermostat. Gas burners will vary from
model to model in size, shape, and relative
location. Some models are equipped with
heat reclaimer systems in which, some of
the exhaust air is recovered and introduced
back into the drying process.
L. STEAM DAMPER SYSTEM
The newest type system is called the
steam damper. It is shown to the right and
it uses a piston with compressed air to
open and close the steam damper, which
in turn allows the air to flow either through
the coil for heat, or under the coil for cool
down. Air supply is 80 psi +/- 10 psi (5.51
bar +/- 0.69 bar).
