Improved infra-red irradiators and use thereof for soldering, domestic water heating, furnace treatment, drying and moisture profiling of paper webs. Burners can have a ceramic fiber mat held over a shallow combustion mixture plenum essentially completely spanned by a baffle. Mats can have folded-in edges to permit close packing. The plenum can have a partition forming a small ignition compartment with an igniter against the covering portion of the mat. Burners can be fitted to heat radial chambers on a rotating table lehr.
