**Procedures for Power Companies’ Thermal Power Plants to Save Oil Usage (Trial) Chapter 1 General Provisions Article 1 These procedures are formulated in accordance with **relevant regulations, in order to strengthen the management of oil usage in thermal power plants and improve economic efficiency. Article 2 These measures apply to the various branches of **electricity companies, group companies, and provincial (regional, municipal) electricity companies. Article 3: The energy conservation work leadership groups of each branch company, group company, and provincial (regional, municipal) power company should regard oil savings as an important part of their energy conservation efforts and provide strong leadership in this regard. The production technology departments of various companies serve as the competent authorities in charge of oil-saving efforts at their respective thermal power plants, and are responsible for overseeing such efforts. Article 4: Oil-saving management should be strengthened throughout the entire process of power plant design, equipment selection, construction, maintenance, and operation, so as to achieve substantial progress in oil savings. 　 Chapter 2: Technical Measures Article 5: All units shall, in light of actual conditions, actively adopt the small oil gun ignition technology to upgrade existing ignition fuel systems. Reduce the oil used for boiler ignition. Article 6: Mature and reliable new types of burners as well as other combustion stabilization technologies shall be employed to modify components such as boiler burners, thereby improving the boiler’s ability to maintain stable combustion at low loads and reducing the amount of oil required for combustion support. Efforts shall be made to ensure that the boiler’s combustion stability meets the following criteria: (–) For boilers burning bituminous coal, the lowest stable operating load without the use of oil for combustion support should be 40%-50% of the rated operating condition ； (II) For boilers burning low-quality coal, the minimum stable load without oil injection for combustion support should be 45%–50% of the rated operating condition ； (III) For boilers burning anthracite, the minimum stable load without oil injection for combustion support should be 50%–55% of the rated operating condition ； 　 For special boilers such as UP direct-flow boilers, the minimum stable combustion load rate with no fuel supply can be determined based on specific conditions. Article 7: Active encouragement should be given to the development and research of new oil-free or low-oil boiler ignition technologies (such as plasma ignition technology), with their prompt adoption. Article 8: Actively create conditions to conduct feasibility studies and evaluations on the fuel-fired units under its jurisdiction, advance the conversion from oil to coal, and significantly reduce the oil consumption in thermal power plants. 　 Chapter 3: Technical Management Article 9: Standardization of maintenance operations shall be fully implemented to improve the quality of unit maintenance, enhance the operational reliability of the units, and reduce the frequency of unplanned shutdowns and reduced output. Article 10: Gradually implement condition-based maintenance for units in order to reduce the frequency of major and minor repairs, thereby saving on costs related to repairs as well as on the oil used for starting and shutting down the units. Article 11: Strengthen operation management and actively adopt unit start-up and shutdown methods that help save fuel. (–) During the cold start of a unit under conditional operations, steam heating from the bottom of the boiler should be activated, and powder transfer from an adjacent boiler should be utilized to reduce oil consumption during the initial stage of boiler ignition. (II) When the unit is shut down normally, sliding-parameter shutdown should be used as much as possible to reduce the amount of oil used during startup and shutdown. (III) Make full use of the unit’s maximum continuous output (MCR) and minimum stable combustion capacity to reduce the frequency of unit startups, shutdowns, and peak-shaving operations, thereby saving fuel used for ignition. Article 12 The following measures shall be taken to further strengthen fuel management: (1) Ensure that the quality of the coal purchased meets the requirements specified for the coal type intended for use in the boilers ； (II) When using a mixed coal blend, the proportion of each type of coal should be appropriate and uniform ； (III) Coal-fired power plants in areas with cold and rainy weather should maintain a sufficient stock of dry coal to prevent excessively wet raw coal from entering the raw coal storage bins (especially in systems with direct coal injection for powder production). Article 13: Further strengthen the management of fuel metering. Each boiler shall be equipped with a fuel flow meter to ensure that the fuel consumption per boiler can be measured and evaluated separately. 　 Chapter 4: Management and Evaluation Article 14: Each unit shall, in light of the actual conditions of its own region, formulate a three-year rolling fuel-saving plan as well as annual work plans, set specific fuel-saving goals and measures, and ensure their thorough implementation. Article 15: Each branch company, group company, and provincial (regional/municipal) power company shall strengthen management and enforce strict evaluation of the thermal power plants under their jurisdiction, establish a comprehensive system of fuel-saving statistics at all levels, prepare a written summary of fuel-saving efforts once a year, and submit it to the Transmission and Distribution Operations Department of **Power Company. 　 Chapter 5 Supplementary Provisions Article 16 Each branch company, group company, and provincial (regional, municipal) power company shall, in light of the actual conditions of their respective regions, formulate detailed rules for oil conservation as well as assessment and reward/punishment mechanisms, and ensure strict compliance with them. Article 17: These provisions shall be interpreted by the Power Transmission and Distribution Operations Department of **Power Company. Article 18 These measures shall come into force as of the date of promulgation.
