DDBS

In the plastic film production lines where is request to flame system to work in a very wide speed operation range is very useful to have two burner /mixture generator. Just one burner /mixture generator don’t have possibilty working from 50 mpm to 500 mpm.

This because we size our system respect to highest speed; he means to stress material treated at lowest speed

It makes non sense to use same energy output when:

•  speed is one third of maximum
•  web thickness is half then previous
•  changes the production type (plain film is harder to be treated and needs more energy then heat sensibility film like coex o white opaque film)

EsseCI has introduced the DDBS (Differentiated Double Burner System) that is a double burner but where the two burners typically do not work simultaneously, but one per time: one smaller in dimension /capacity/power that work with lower speed (for example from 50 to 200 mpm) and the other bigger for work at higher speed (300 mpm to 500 mpm).

Burner n°1 is equipped with a narrower grid and with less powerful mixture generator then the second
