Pulse Combustion Control Technology for Oxygen Atmosphere

A new combustion control method for oxygen-enriched or pure-oxygen ceramic roller kilns is proposed in this paper. This kind of roller kiln uses high-concentration oxygen or pure oxygen as the combustion-supporting medium. The new method introduces the pulse combustion control technology into the ceramic roller kiln to fine tune its oxygen-and-gas proportional regulator. This technology can greatly improve the combustion performance and thermal efficiency. It also meets the requirements of the sintering process well. This paper first analyzes the significance of this research by comparative analysis, and then discusses the configuration and implementation of the control system. Finally it gives the hardware and software design for the whole system. This system can automatically regulate the ratio of oxygen to fuel gas and the pulse combustion time of the mixed gas. In practice, it optimizes the combustion atmosphere, improves the thermal efficiency and products quality and reduces energy consumptions.
