Abstract
A method of reducing carbon monoxide and hydrocarbon emissions in a rotary glass fiberization process utilizes a fiberizing spinner with fiberizing holes through which molten glass is passed by centrifugal force to form primary fibers which pass through an annular heat bath region and attenuation fluid emitting apparatus that forcefully emits an attenuating fluid to attenuate the primary fibers into finer diameter fibers. Oxygen is introduced into the annular heat bath region to oxygen enrich the annular heat bath region and is combusted in the annular heat bath region to materially reduce carbon monoxide and unburned hydrocarbon emissions produced by the process.
