Steam Purge System
The steam purge is a system that helps prevent the burner from shutting off. The target steam rate is 12 psi.
The burner will shut off when the boiler pressure reaches 13 psi. The
steam purge valve opens to relieve
pressure in the boiler at 12.5 psi.
The steam purge most commonly occurs during initial startup to purge oxygen and when turning at the end of
a
windrow when steam is turned off.
The steam purge valve is open when the
“Steam Purge” indicator is black
The steam purge system turns on automatically at
50% and above. It turns off automatically at 49% and
below.
