Spectrum VIR VI Mounting Hardware
The flame scanner mounting configuration is based
on the design of the boiler and/or burners.
Direct sighted viewing heads are suitable for most
applications, particularly in front and opposed wall-fired boilers.
This configuration is designed to look straight through the windbox
or burner to the target flame. The burner front mount fixes directly
to the windbox wall or burner front and is equipped with an integral
purge air connection.
Fiber-optic viewing head assemblies are used on installations
where it is not always possible to maintain a direct sight on the
burner flame. The rigid fiber-optic assembly is used in deep windbox
applications to ensure an unobstructed view of the flame. The flexible
fiber-optic assembly is designed for use on the tilting burners
found on Combustion Engineering (CE) tangentially fired boilers.
The rugged design allows the assembly to move with the tilting bucket,
ensuring a constant sight of the burner flame. Both fiber-optic
styles include a guide tube, facilitating removal of the scanner
head for maintenance and cleaning.
Both mounting configurations are supplied with a
local junction box which serves as a connection point between the
viewing head and the scanner rack. The cable from the junction box
to the viewing head is equipped with a quick-disconnect molded connector
that mates with the head electronics.
