Innovative Clean Air Technologies Grant Report: Oscillating Combustion on a High-Temperature Forging Furnace

Presentation
Research Project

Overview

Gas Technology Institute (GTI) has developed a system for reducing the formation of NOₓ in high-temperature industrial furnaces, such as glass furnaces, forges, metal-melters, and cement kilns. Such furnaces generally do not have flue gas treatment for NOₓ and cannot employ highly effective combustion modifications. In GTI's system, the flow of natural gas to the burners is pulsed with a special valve, creating a sequence of rich and lean sub-zones in the combustion zone of the furnace. This rich-lean pattern reduces the formation of NOₓ in the flame. In the ICAT project, GTI has installed and tested oscillating-flow valves on a forging furnace at Shultz Steel Company in South Gate, California. With these valves, GTI achieved almost 50 percent reduction of NOₓ.
