DL/T 561-1995 in English

1.1 The power plant's steam generation equipment, chemical monitoring is to ensure the security, economic, and stable operation of one of the important part. To meet the high-parameter, large-capacity thermal power needs of rapid development, especially development of the guidelines.
1.2 In order to prevent quality deterioration caused by water and steam equipment accidents, we must implement the "prevention first, quality first" approach, do a good job monitoring the whole process of chemical water and steam quality management. New thermal power plant selection from the water, water treatment system design, equipment and materials selection, installation and commissioning, up to equipment operation, maintenance and deactivation should adhere to quality standards at all stages to ensure the quality of 100% of the water and steamline This guide provides the standard value, ensure that equipment is not due to thermal corrosion, fouling, salt accumulation and accidents.
1.3 The power control (power) the leadership of Council Chief Engineer Chemical monitoring the whole process of quality management. Chief Engineer and chemical professional engineer should always understand and grasp the overall situation of the chemical monitoring, coordination and implementation of the chemical monitoring of the relevant work experiences, and continuously improve the level of the chemical monitoring.
1.4 Thermal Power Plant construction period of the chemical monitoring should be undertaken by Power Construction Company (Board) is responsible for organization and implementation. The supervision must be included in the progress of its implementation should be used as a basis for assessing the quality of works.
1.5 Thermal Power Plant Chief Engineer shall organize and lead steam turbine, boiler, electrical, thermal control, chemical professionals and long-run value of thermal equipment to study the corrosion and scaling problems, analyze the causes, clear division of labor, to implement measures to continuously improve the equipment health, to prevent accidents.
1.6 Chemical water and steam power plant to supervise the work well, we must give full play to the chemical responsible for personnel oversight. Chemical personnel should be responsible for timely and accurate detection of water and steam quality and heat the whole factory equipment corrosion, fouling, salt accumulation level. Abnormal, the leading power plant should be a written report, analyze the causes and make recommendations as a preventive measure. Chemistry should be a dedicated team under the leadership of Chief Engineer, supervision, inspection departments to realize such corrosion, scale measures, so that the quality of water and steam back to normal. When necessary, the chemical responsible for a written staff report can also copy to electronic tubes (Electricity) Board.
