ABSTRACT:
Methods and equipment are disclosed for production of mineral fibers, by attenuation, involving the use of a substantial volume of gas, in which water is also employed at least in a fiber binder, the methods and equipment providing for recirculation of most of the gases, and preferably also of the water employed in the system. Both the gases and the water are purified and the pollutants are separated and are also treated to convert the pollutant constituents to a form not ecologically objectionable for disposal. The methods and equipment also minimize discharge of fluids and aural efflux from the plant. Methods and apparatus are also disclosed for controlling and stabilizing various operating conditions of the fiberization; such as the temperature and the pressure in the fiber forming section or chamber.
