| 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. The influence of this technology upon the environment and the economic behavior is discussed, and problems in engineering application needing to pay consideration being put forward. It is believed that this technology has obvious environmental and economic superiority. |
