The main parts of the model P-5050 TEG, with CP attached, are shown in Figure 3.
4.1.1 Fuel System
Components making up
the fuel system control
the input of fuel to the
burner. The primary con-
trol is a pressure regulator
that modulates fuel mani-
fold pressure to a meter-
ing orifice. The pressure
regulator includes a sedi-
ment bowl with a manual
drain cock and fuel filter
to remove fuel impurities.
The fuel filter has a resin
impregnated cellulose
element which prevents
solid particles from dam-
aging the regulator and
downstream parts.
The outlet of the pressure
regulator leads to a mani-
fold on which is mounted a pressure gauge to monitor the fuel pressure, and a pressure
switch for the SI module. The fuel flows through the manifold to the fuel line which connects
to an orifice mounted on the front of the burner. The orifice contains a jewel with a precisely
sized hole to meter the fuel flow into the burner. A solenoid valve (SV) is plumbed between
the manifold and fuel line.
The solenoid valve is controlled by the Ignition Control System. The Ignition Control System
opens the solenoid valve when the fuel pressure switch is closed (fuel pressure is present),
and closes the solenoid valve when fuel pressure switch is open (no fuel pressure) or the
Ignition Control System does not detect combustion. The main parts of the fuel system are
shown in Figure 4.
An optional NACE compliant stainless steel fuel system is available as an option.
