The No.1 unit of Guangzhou China Resources (CR) Thermal Power Co., Ltd., a transformation demonstration project for “ultra-clean emission”, was formally put into operation on July 21. During the test run of 168 hours, the concentration of nitrogen oxides, sulfur dioxide and smoke and dust emitted by this unit was stabilized in a range of 5-30, 2-20 and 0.5-3mg/standard cubic meter. On August 4, the on-site monitoring result of Guangzhou Mechanical and Electrical Industry Environmental Monitoring Station showed that the concentration of nitrogen oxides, sulfur dioxide and smoke and dust emitted by this unit was 23, 6 and 2.56mg/standard cubic meter, all lower than the “special emission limits of the air pollutants of gas turbine” in the key areas of the country and up to the “50355”standard of Guangzhou City for “ultra-clean emission”. After the transformation, the annual total emissions of nitrogen oxides, sulfur dioxide and smoke and dust by the No.1 unit will be reduced by over 50%, 82.5% and 75% respectively, making the unit one of the most environmentally friendly coal-fired units in China at present.

The No.1 unit is one of the 13 coal-fired units as the transformation demonstration projects for environmental protection approved by the National Energy Administration and also the first transformation project of CR Power for “ultra-clean emission”. A lump-sum investment of over 70 million Yuan was made in this phase of project, including the optimization of denitration catalyst repair and ammonia injection and transformation of denitrification air preheater, high-frequency power supply for electrostatic precipitator, desulfurization and compatibilization, wet electrostatic precipitator and chimney. So far, the transformation of the No.2 unit of Guangzhou CR Thermal Power Co., Ltd. for “ultra-clean emission” has been started, and the whole transformation work for environmental protection is expected to be completed in the first half of 2015.
