【摘要】 本文主要介绍了烟塔合一技术。烟塔合一技术可以简化湿法脱硫系统,不再需要净烟气再热器,取消了传统火电厂的烟囱,可以将锅炉引风机和脱硫增压风机合而为一,大大降低电厂建设费用,降低发电成本。更为重要的是,烟塔合一技术可提高脱硫后净烟气的抬升高度,有利于降低污染。本文首先介绍了烟塔合一技术的概念;接着就烟羽抬升高度和和传统的烟囱排烟方式进行对比计算,然后分析了烟塔合一技术对冷却塔的热力性能和塔内的流场的影响;最后,分析了该技术的经济性。总之,烟塔合一技术是脱硫技术发展到一定程度的必然产物,它以其独有的技术、经济、环保优势,将逐步在燃煤机组脱硫系统中得到应用和发展。更多还原

【Abstract】 This paper is about the technology of discharging flue gas after wet desulfuration through natural draft cooling tower. This technology can improve energy efficiency, simply flue gas system, and need not construct chimney and GGH heat exchanger. Power plant boiler air-introduced fan and FGD pressurized air fan can be united. Expenses of power plant construction are decreased. All of these can help reduce the cost of electricity generating. It is important that the technology can increase the uplift height of gas after desulfurization, and thus reduce atmosphere pollution.The definition of this technology is firstly introduced in this paper. Then Calculate and Contrast on the plume height and elevation of flue gas with the traditional way of comparison, and then analyzed the NDCT with flue gas injection technology to the cooling tower and the tower thermodynamic performance of the flow field, It is believed that this technology has obvious environmental and economic superiority.更多还原
