As the Unitherm M.A.S. burner with its patented M.A.S. system for simple and safe flame shaping can be easily operated, it is also easy to execute the burner with control equipment for automation.
|Usefuel automation steps:||Remote controlled:||Standard execution:|
|Air pressures on burner||pressure transmission||pressure indication|
|Flame shape adjustment||motor actuated rack and pinion drive incl. feedback control for setting||manual rack and pinion drive|
|Primary air butterfly valve||executed with a pneumatic or electric actuator incl. positioner (feedback)||adjustment with manual hand lever|
|Central air butterfly valve||executed with a pneumatic or electric actuator incl. positioner (feedback)||adjustment with manual hand lever|
|Cooling air valves (different settings for fuel in use)||executed with a pneumatic or electric actuator||adjustment with manual hand lever|
|Lance retraction(s) if burner is equipped with oil lance(s)||pneumatic retraction cylinder||manually retracted|
|Input-, feedback- and pressure transmissions are performed by 4-20 mA signals.|
Automation module 1
With above recommended equipment for automation the burner can be simply operated by [+] [-] setting commands given from the control room via a PLC or other control equipment.
A kiln camera and a shell temperature supervision system should be available.
Automation module 2
In case the primary air fan is equipped with a flow measurement and/or a variable speed control the degree of automation can further be increased. This is done in combination with a Burner Management System by Unitherm Cemcon. It enables the creation of control loops for burner set-points and semi-automatic operation. The evaluation of burner data like setting feedbacks and an internally calculated burner momentum are also provided.
Automation module 3
Is the burner equipped with automation module 2 the burner can be operated by AUTOMIZED FLAME CONTROL (process supervision by digital picture processing -flame analysis) together with a kiln optimisation (PiT Navigator, LINKman, etc.)
Basically all M.A.S. burners equipped in standard execution can be retrofitted for automation.
