Based on years of engineering practice, the five channel pulverized coal burner is developed by fully analyzing the advantages and disadvantages of the company's original four channel pulverized coal burner, adopting the large speed difference and strong swirl theory of modern latest combustion technology, combining with pulverized coal combustion characteristics, using computer simulation technology, and comprehensively considering multidisciplinary research and development achievements. The burner is suitable for cement industry and other kinds of rotary kilns. It has the remarkable technical characteristics of low proportion of primary air consumption and large combustion thrust. Its high-speed outlet jet greatly enhances the mixing of pulverized coal and high-temperature secondary air, and improves the combustion effect of pulverized coal. The burner has strong firepower, reasonable flame shape, and strong adaptability to all kinds of coal quality, including anthracite and low calorific value inferior coal; Its structure design is exquisite, the means of flame adjustment is simple and applicable, and the flame shape can meet the needs of working conditions in the kiln at any time, which is conducive to the completion of reasonable calcination system and the improvement of product quality; Its excellent combustion characteristics, significant play, improve the calcination ability of rotary kiln and improve product quality.
