摘要
Abstract
The characteristics of cold flow field of an oxygen-enriched burner was studied that was applicable to petroleum coke powder industrial boiler. Low temperature tracer method and Infrared imaging temperature measurement were applied. Through the infrared imaging processing and jet temperature field analyzing, this paper revealed the mixing characteristics of flow field outside the burner. Experimental results indicate that, the burner has good aerodynamic field, the primary air has a bigger radial, whereas smaller axial temperature-speed gradient, and pure oxygen jet has a strong rigidity and it keeps a reasonable mixing distance from the primary air. The mixing effect of primary air’s flow field in the high-speed air jet burner is obviously influenced by the blunt body flaring and center pipe. Meanwhile, axis temperature, jet expansion angle, range, and center reflux area of the primary air all also present certain changing rules separately.关键词
