摘要：With the development and operation of the bench-scale opposed multi-burner gasification system and the application of advanced visualization techniques, the particle deposition characteristics in a gasifier has been studied. The particle deposition characteristics are mainly divided into four different types: particles impact and adhere, particles impact and rebound, particles detach after adherence, and particles impact and break up. The high-temperature and low-temperature particle deposition characteristics are discussed separately. The probability of low-temperature particle impact and adhere (39.50%) is approximately the same as that of impact and rebound (45.50%), and the proportion of adhered particles detach from refractory wall is 12.50%. The probability of high-temperature impact and adhere is 75.70%, which is much higher than that of impact and rebound (21.10%), whereas only 0.80% of high-temperature particles detach after adherence. The proportion of particle break up is almost the same for both high- and low-temperature particles, with a percentage of similar to 2.50%. (C) 2015 Elsevier Ltd. All rights reserved.
