Oxy-boost control in furnaces

摘要

A process controls oxy-boost firing and air-fuel burner firing in furnaces, including large glass furnaces (100) such as float furnaces. The large side-fired regenerative float furnaces (100) use oxy-boost firing for a variety of reasons, including production increase, improves glass quality, lowering of superstructure temperatures, and reduction of emissions. An adaptive controller (134) receives input data from process parameter sensors (122) throughout the furnace, and adjusts its control logic for controlling both the oxy-boost burners (120) and the air-fuel port burners.
