Electrical furnace, zones balanced with a symmetrically tapped transformer |
摘要 |
A glass melting furnace is divided into a number of heating zones. Each of the heating zones is connected to a common transformer output but is symmetrically tapped to the secondary of the transformer with respect to each of the other zones. In this way, the heating effect in the different zones can be balanced with each other. With a single transformer output, it is possible to introduce heating variances along the length of a flow channel or to produce voltage variations across different zones wherein the electrodes of each respective zone are of different spacing. Heat can be evenly developed along the length of the flow channel or in irregular spaces, such as corners or turns in the flow channel.
