Abstract

See full text

A method for providing fresh air fed through a fan to a burner of a dryer, thereby charging the burner, when the dryer is operated with recirculating air. In commercial dryers in which the drying air is heated by a burner, it is customary to reuse the moist air leaving a drum containing the laundry to be dried as recirculating air. The recirculating air component is increased with increasing drying of the laundry. At the end of the drying operation, when the moist air no longer contains as much moisture as at the start, the moist air is used as recirculating air. The burner then no longer gets enough combustion air, which leads to an incomplete combustion. The dryer can be operated with a higher recirculating air component, an optimal combustion being guaranteed through the charging of the burner with fresh air. The invention permits more economical drying.
