    • A method of manufacturing mineral fibers includes rotating an orificed spinner (12) and supplying molten mineral material to the spinner to centrifuge streams (26) of molten mineral material. A downward annular flow of attenuating gases is directed to attenuate the streams of molten mineral material into mineral fibers (28). A mixture of combustion air and combustion gas is supplied to an annular burner (14) positioned around the spinner. Heat from the annular burner is directed toward the spinner and the streams of molten mineral material to heat the spinner and assist in attenuating the streams of molten mineral material into mineral fibers. A pressure sensor (54) senses the pressure of the combustion air prior to the introduction of the combustion air to the burner. The pressure of the combustion air is controlled in response to the sensed pressure to maintain the pressure of the combustion air at a specific pressure. Alternatively the temperature of the combustion air befor the burner is sensed and controlled, or the combustion air is dried prior to introduction to the burner.
    • 一种制造矿物纤维的方法包括旋转一个有孔的旋转器(12)并将熔融矿物材料提供给旋转器以离心熔融矿物材料的流(26)。 导向的向下环形的减弱气体流被引导以将熔融矿物材料流减弱成矿物纤维(28)。 将燃烧空气和燃烧气体的混合物供应到位于旋转器周围的环形燃烧器(14)。 来自环形燃烧器的热量指向旋转器和熔融矿物材料流以加热旋转器并且有助于将熔融矿物材料流减弱为矿物纤维。 在将燃烧空气引入燃烧器之前,压力传感器(54)感测燃烧空气的压力。 燃烧空气的压力响应于感测的压力而被控制,以将燃烧空气的压力保持在特定的压力。 或者,燃烧器的燃烧空气的温度被感测和控制,或者燃烧空气在引入燃烧器之前被干燥。
