  • Method and apparatus for controlling temperature within a furnace
    Patent number: 4028083
    Abstract: A furnace, which includes a melting and refining tank and a forehearth, is divided into a plurality of zones or regions. Each of the zones is provided with means for sensing temperature within the zone and a means for heating the zone. Means is also provided for measuring the individual heat input into the furnace of the heating means in each of the zones. When changes in temperatures are required, the temperatures in the different zones of the furnace are controlled by adjusting the heat input of the heating means in at least one of the zones to cause the temperatures in each of the zones where changes in temperature are required to approach desired temperatures.
