Abstract

Apparatus for drying a continuously moving web containing a combustible organic liquid comprises a walled chamber through which the web passes. Ignition and heating means adjacent the inlet of the web to the chamber initiates combustion of the organic liquid. Enroute to the web outlet of the chamber the web passes between heat radiating members located on opposite sides of the web so as to define between the heat radiating members a main combustion zone. Hot waste gases of combustion are led from the main combustion zone to an after combustion zone defined in part by the heat radiating members and in part by guide members located within the the chamber. The waste gases are drawn through the after combustion zone to waste gas outlets by means of a suction fan, the heat radiating members being heated by the waste gases.
