NUMERICAL STUDY OF PARTICLE NUMBER DENSITY DISTRIBUTION IN SCRUBBING-COOLING CHAMBER OF GASIFIER
IntroductionFrom the perspective of energy security and environmental sustainability, highly effective uses for fossil fuel in energy industries are demanded. Since coal is one of the most important fossil fuels in the world, coal gasification technology appears to be an inevitable choice for power and chemicals production and has a leading place in Clean Coal Technology (CCT) 1. Power plants such as the Integrated Coal Gasification Combined Cycle (IGCC) are being developed worldwide to use coal more efficiently and cleanly 2-4. In the past years, a number of entrained-flow coal gasifiers have been built in China. At present, the basic research of large-scale and high efficiency entrained-flow coal gasification technology is being developed in China. In entrained-flow gasifiers, coal water slurry or pulverized coal is gasified at high temperature and under high pressure. The high-temperature syngas produced in gasifier comes into scrubbing-cooling chamber. The temperature of syngas decreases dramatically due to the rapid evaporation on the liquid-gas interface in cooling ring and cooling tube of scrubbing-cooling chamber as shown in Figure l5-7. At the same time the molten slag also
