The S & J Biogas 97141 Flame Trap Assembly combines
the 97130 thermal operated valve with the
94309 plate flame arrester to
effectively inhibit flame propagation in low pressure gas lines.
The
flame arrester quenches the flame front by cooling the flame below its
ignition temperature. The flame front enters the arrester and the flame
is intercepted by the arrester element which is specifically designed to
provide a precision path for the flame to follow. The flame front temperature
is reduced to below the ignition point of the protected vapors. This is
achieved by dissipating the heat of the flame through the arrester elements
and body. The spring loaded thermal valve quickly closes when the fusible link
is melted in the presence of fire. This shuts off the flow of gas to prevent
catastrophic damage.
The fusible element is easily replaced without disassembling
the valve. Other valve elements are also easy to replace which simplifies
maintenance.
Its aluminum and stainless steel components withstand the severest
of process environments. The S & J Biogas 97141 is especially designed for hydrogen
sulfide and hot, wet methane which are the main components of digester gas streams
in municipal waste water treatment facilities.
