Recently, China Power Investment Group Yuanda Environmental Protection Co., Ltd. has completely independent intellectual property rights and has passed the expert appraisal of YD-BSP flue gas desulfurization complete sets of technology and equipment. Experts believe that the overall technology of this achievement has reached the domestic leading level, and the online monitoring technology of limestone activity has filled the domestic gap and ranks among the international advanced, with significant economic and social benefits.
According to reports, the technology is a cooperation between CPI Yuanda Environmental Protection Co., Ltd. and Chongqing University. Based on the introduction, digestion and absorption of wet flue gas desulfurization technology, the company will re-innovate the key technologies. The use of this complete set of technology and equipment can greatly reduce the investment operation cost of flue gas desulfurization, so that the cost of flue gas desulfurization equipment does not exceed 200 yuan / kW, which is lower than the key points of the national ministry and commission in the localization of key technologies and equipment for flue gas desulfurization in thermal power plants. The control target of 700 yuan / kW is proposed in the article. After applying this technology, Huaneng Beijing Power Plant's 4×250 MW unit can save about 14 million yuan in operating costs each year.
