Abstract: A curing oven system for drying and/or curing building materials. The curing over system has at least one curing oven configured to be heated by at least one heating device and having at least one curing oven zone for drying and/or curing the building materials, and at least one conveying device for transporting the building materials through the curing oven. The curing oven comprises at least one electrical heating device and may also include a non-electrical heating device. Also a method for operation such a curing oven.

Abstract: A heating coil for an oven. The heating coil comprises a heat source for emitting energy, wherein the heating coil is configured so that a first fluid flows around the heat source. The heating coil further comprises a cleaning device having a nozzle pipe with a plurality of nozzles. A cleaning fluid emerges from the nozzles under overpressure compared to the first fluid and flows around the heat source to clean the heat source. The nozzles are arranged in at least two lines along the nozzle pipe and the at least two lines are spaced radially from one another along the nozzle pipe.

Abstract: A curing oven, particularly for curing a continuous mat of mineral wool fibres mixed with binder has an air injecting system for injecting ambient air into at least one heating zone in circumstances in which there is a risk of inadequate ventilation.
