Abstract
This paper describes the severe air pollution and ultra-low emission process route in China today, based on which it studies and analyzes the LGGH high-efficiency coal-fired flue gas treatment technology applicable to the upgrading of the ultra-low emission with respect to its origin, composition, characteristics and advantages. Then this paper gives a case study on the application of this technology in Yudian Dabu Power Plant where ultra-low emission is required, in particular the project profile of Yudian Dabu Power Plant, and specific proposal, process layout, main design parameters, technical features and operating result of the technology in the power plant. According to the testing, after this technology is put into use in the plant, the dust and SO<sub>3</sub> emissions of Unit 2# chimney drop to 2.3mg/m<sup>3</sup> and 2.4 mg/m<sup>3</sup> respectively, much lower than the national ultra-low emission limits. All these can demonstrate that the large-scale coal-fired power units can achieve a significant result by adopting the optimized LGGH high-efficiency coal-fired flue gas treatment technology, this technology provides higher precipitation efficiency, energy conservation and emission reduction, and high-efficiency SO<sub>3</sub> removal, solves the problem of "Gypsum rain" and visual pollution, and realizes dry chimney discharge, indicating that this technology deserves promotion and has great potential to become a popular post-combustion flue gas treatment technology.
Highlights
In recent years, haze has frequented the Beijing-Tianjin-Hebei region and the Yangtze River Delta, and people attach increasing importance to environmental protection
The actual good application effects further strengthen the confidence of using Longking Gas Gas Heater (LGGH) high-efficiency coal-fired flue gas treatment technology in Dabu Power Plant
Compared with traditional low-low-temperature high-efficiency coal-fired flue gas treatment technologies, the LGGH applied in Dabu Power Plant is a technical innovation: i
Summary
Haze has frequented the Beijing-Tianjin-Hebei region and the Yangtze River Delta, and people attach increasing importance to environmental protection. In September 2014, the National Development and Reform Commission, the Ministry of Environmental Protection and the National Energy Administration jointly issued Action Plan for Upgrading and Transformation of Energy Conservation and Emission Reduction of Coal Power [2], which even requires clean emission nearby the gas units of coal-fired power plants. As national and local policies for ultra-low emission are issued successively, upgrading and transformation of coal-fired power plants for ultra-low emission remains the key direction of environmental protection in power industry in future. The technology for post-combustion flue gas treatment or ultra-low emission varied greatly. In this context, to select a high-efficiency, economic and comprehensive emission technology becomes an urgent task for emission treatment of coal-fired power plants. To avoid the risk of overlapping investment, prolonged construction period and power loss after the start of power generation and to achieve the goal of ultra low emission, we optimized the technology scheme in light of the original design and construction schedule and based on the local conditions
