activities, comprehensive and tamping Safety Foundation ... Troubleshooting, management mechanism, give full play to role of technical supervision and realization of troubleshooting, management, improved process management. This year completed the boiler lower header leakage, boiler pressure, a major risk management, completed 29 of great risks and 3 General problems of governance. Complete chemistry lab construction, thermal control, and complete the boiler scale integrated management, host shafting vibration of 10 scientific and technological projects, such as. 　　Complete supercritical 630MW on-line simulation system development and application of circulating water MCC standby power transformation, the transformation of desulfurization waste water, the unit water supply system of comprehensive treatment and discharge valve modification of coal mill 5 key technological transformation projects, group health is improved. --Science and technology innovation is further increased. Strengthen the characteristics of supercritical unit major issues, gradually clearing the particularity of supercritical unit and regularity. Developed motor oil time management, switch action times, statistics, coal-aided measurement software, improves the production level of lean

management. Increased investment in science and technology, reporting science and technology projects and 14 technical project total cost percentage of the total annual production output of 0.25%. "Large-scale coal-fired power plant flue gas desulfurization, denitrification complete development and application of key technologies" project, won the national science and technology progress second prize. 630MW supercritical units optimized control strategies and the 630MW development and application of on-line simulation system for supercritical units, supercritical 600MW units of turbine driven boiler feed pump set of comprehensive treatment of defects Datang technology respectively one or two and third. 　　Meanwhile, information technology achievements, the company was named "China power information technology benchmarking enterprises." --Repair and maintenance has improved further. Modify the inspection standards and standards on a regular basis, standardizing work procedures, checking and inspection project. Deepening the BFS++ system, and implements maintenance information shared. Reorganizing RB logic again, and ensure the success of the RB. Innovating the mechanism of maintenance management, implemented a project manager system.

Successful completion of two autonomous maintenance, reliability improved steadily. Implementing two c-level maintenance, project themselves 48.7% and 42.3%, respectively. Accomplish two circulating pumps repair and overhaul of four Mills, maintenance teams to get exercise. 　　Promote the work of energy saving and consumption reducing, complete the unit energy consumption diagnosis, plant water balance test, 10 energy-saving projects. 　　Second, we should adhere to "three" on the economic benefits of improving, outreach
