BCU 370
Application
1 Application
The BCU 370 burner control unit controls, ignites and
monitors industrial forced draught burners of unlimited
capacity in intermittent or continuous operation.
It can be used for directly ignited forced draught burn-
ers or forced draught burners ignited with pilot burner.
The BCU 370 activates the fan and sets the connected
butterfly valve to Pre-purge and Ignition position. After
pre-purge and burner start, the enable signal is issued
to an external controller which positions the butterfly
valve in accordance with the capacity demand. Post-
purge occurs after the end of burner operation. The
burner control unit BCU 370 monitors the gas and air
pressure. An optionally integrated tightness control
function checks the valves with an external gas pres-
sure switch.
Programmability by means of the optical interface and
BCSoft PC software guarantees optimum adaptation to
the relevant application. Adjustable start-up attempts
and automatic restart which can be activated ensure
the high flexibility of the burner equipment.
The quick-start option allows standard-compliant start-
up of the forced draught burner without pre-purge
after controlled shut-down. This avoids unnecessary
admission of air into the combustion chamber. The heat
output is available as quickly as possible after a tem-
perature demand.
