Abstract

By changing the additives to an off-gas system in an incinerator bag house, by replacing part of a normally added calcium compound with a sodium compound, one can reduce the amount of sodium compound needed for a combined off-gas from incineration and glass melting system, reduce the amount of glass produced for a given amount of waste to be incinerated, and thereby reduce the cost of installing a glass melter and the cost of energy (electricity) needed to produce glass.
