Study On Tower's Interior Flowing Of Natural Draft Cooling Towers With Flue Gas Injection

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.
