Preface The objective of the environmental auditing is to retrospect the existing production facilities in the Power Plant, to identify the problems of present production process, pollution control measures, environmental management, safety management and social impacts, etc., and to propose solutions accordingly. An environmental auditing can effectively reveals the problems of enterprise in environmental management, and enhances the environmental protection awareness among the relevant departments in the enterprise for strict implementation of environmental protection policies. It also helps the enterprise to build a favorable and responsible image in the light of long- term development and social responsibility, through attaching importance to environmental protection in order to enhance the environmental protection awareness in the whole society. Shanxi Yangguang Power Generation Company Ltd. was established in December 1993, and its four power generation sets were put into production in November 1999, presently as one of the key power plant in Shanxi Power Grid, with installed capacity is 4×300MW. The power plant has 1542 employees, with registered capital of 1.1 billion RMB. In 2006 the annual power generation was 8.23 billion KWh, and the resulting sales revenue was 1.85994 billion RMB including net profit of 122.55 million RMB; the profit plus tax of 491.17 was million RMB. While converting coal into power energy, the power plant consumes huge amount of coal and water resources and emits substantial pollutants like SO2, particulates, NO2, etc. into the environment. This document reports the environment auditing results on the measures presently taken by the Power Plant in environmental control and management. China Institute for Radiation Protection 1 Environmental Auditing Report for Energy Conservation Project in Yangguang Power Generation Company Ltd. 2 Overview 2.1 Overview of the Enterprise Shanxi Yangguang Power Generation Company Ltd. was from the former Second Power Plant of Yangquan, Shanxi, as a national key project of the “8th-five-year plan” with total investment of 5.5 billion RMB. The total installed capacity consists of 4×300MW coal-fueled turbine power generating units. The project was initiated on December 25, 1993, and the four turbine units were consecutively put into production on December 1996, November 1997, December 1998 and November 1999. Yangguang Power Plant is at Pingding County of Yangquan City, 120 km from Taiyuan City. The company is in the core area of Xiyang coal mine region, it mainly depends on locally produced anthracite as fuel, which is transported to the Plant via highway and special railway. Water is supplied through the “Water Elevation Project from Niangziguan to Pingding”. The four turbine units are connected to the power grid through 8-circuit transmission lines. Yangguang Power Plant is presently one of the extra-large combustion power generation plants at million- kWh scale in Shanxi province. The main equipment in Yangguang Company is as follows. The boilers of Turbine Units 1 and 2 are of Type DG1025/18.2- 7“W” manufactured by Dongfang Boiler Group Co., Ltd. (flame, positive pressure direct blowing, subcritical, one-interval reheat, natural circulation). The boilers of Turbine Unit 3 and 4 are of Type B WB-1025/18.3-M“W” manufactured by Babcock & Wilcox Beijing Company Ltd. (flame, middle-storage, subcritical, one-interval reheat, natural circulation, drum type). The condensing turbines are of Type N300-16.7/537/537-4 manufactured by Dongfang Steam Turbine Plant. The power generators are of Type QFSN300-2-20 manufactured by Dongfang Electrical Machinery Company Limited. The main control system includes the Distributed Control System by Siemens of Germany and the Electro-hydraulic Control System by Bailey Company of USA. From 2004 to 2007 Yangguang Power Plant invested 365 million RMB to upgrade and renovate the environmental control facilities to reduce air pollutant emissions contributing to the improvement of local and regional environmental quality. The renovation mainly included ash yard leakage proof, dry ash disposal system of Boilers 2~4, installation of wet desulfuration for Boilers 1~4, change of electrostatic precipitators into baghouses for Boilers 3~4, upgrading of control system in electrostatic precipitators of Boilers 1 and 3, renovation of chemical waste water treatment system, and the building of dust suppression and Wind proofing wall in coal yard. In the first year of the “11th Five-year Planning”, Yangguang Power Company set up the goals of “Yangguang of Harmony, Yangguang of Environment Protection, and Yangguang of Development”. The major actions include the flue gas desulfuration project for all four turbine units. Yangguang Power Company, in pursuit of best economic benefits for the enterprise, actively responds to the calls by the municipal government of “Developing the Chinese ‘Ruhr’ and Constructing Shinning Pearl City in East Shanxi”. The Company has invested 240 million RMB for this flue gas desulfuration project, which is implemented as a major action of “Administration- of-Virtue Project” and for the promotion of the enterprise’s sustainable development. The desulfuration project was officially started on April 18th, 2006, also as one of the 100 key projects designated by Yangquan Municipality. The desulfuration facility of Turbine Unit 3 smoothly finished its 168-hour test operation on September 11th, 2007 after the successful 168- hour test operations of such facilities of Turbine Units 1, 2 and 4, which marked completion of the flue gas desulfuration project for 4×300MW Turbine Units in Yangguang Power Company, the first 1,200-MW power plant with once-for-all desulfuration renovation for its turbine units in Shanxi province. The flue gas desulfuration facility for turbine units at Yangguang Power Company uses wet limestone-gypsum flue gas desulfuration technology, with is widely found in large turbine units in China. This technology is featured by maturity, low cost, short construction period and reliable operation. During trial period the facility operation was normal, achieving 100% of automatic thermodynamic input rate, 100% of interlock protection device usage, and China Institute for Radiation Protection 2 Environmental Auditing Report for Energy Conservation Project in Yangguang Power Generation Company Ltd. 100% of gauges application. All the performance indictors are satisfactory and the desulfuration efficiency is more than 90%. The annual SO2 emission reduction is more than 30,000 tons, and the emitted SO2 concentration is within the limits for time-phase-III as defined in “Emission Standard of Air Pollutants for Thermal Power Plants” (GB13223-2003), which effectively improves the local air quality. The operation of this desulfuration project is indeed to play an active role in the mission by Yangquan Municipality of “blue sky, clear water, and green home”. Yangguang
