Tunnel Dryer Burner for an Industrial Laundry
A 2 t/h tunnel dryer struggled with wet spots from uneven heat. A Baltur modulating burner with an integrated Dungs combo valve spread the hot air evenly and trimmed gas use.
The challenge
Uneven heat left wet spots and forced a second pass on linen.
The old burner cycled harshly, shortening belt and fan life.
Gas cost per kg of dry linen was above target.
The plant ran 20 h/day and could not spare long stoppages.
What we supplied & did
Fitted a Baltur TBG90 modulating burner for continuous 20-100% heat output.
Used a Dungs integrated combo valve to absorb inlet pressure swings.
Added pressure monitoring and a Siemens program controller for safe automatic starts.
Tuned air/fuel on site to even the hot-air distribution along the tunnel.
Measured results
What changed on the line
Linen dries evenly on the first pass, removing re-work and freeing capacity.
Modulating output replaced harsh cycling, easing wear on belt and fans.
Gas per kg of dry linen dropped about 10%.
Changeover was completed within a single off-peak shift.
