At 12:44 on May 30, Shenmu Calcium Carbide Unit 1 of Shaanxi Jintai Chemical Technology Group Co., Ltd. was successfully connected to the grid for power generation after repair. All parameters were stable and indicators were excellent, marking the successful completion of the 2024 major overhaul work.

    This repair project of Unit 1 has many A projects, tight construction period, high risks, and complex construction team. A total of 435 maintenance projects have been completed, which is the maintenance with the greatest difficulty factor since it was put into operation.

    In order to realize the grid connection of the unit on schedule, Shenmu Calcium Carbide coordinated and scientifically formulated the unit maintenance plan, maintenance network diagram and subsystem trial operation plan, prepared relevant technical measures and test plans, and completed OPC overspeed test, electrical overspeed test, mechanical overspeed test, etc. as planned. Test work. During the start-up process, precautions in each stage of boiler ignition and unit start-up were strictly implemented, and start-up tests, equipment debugging and other related work were completed with high quality. With the joint efforts of all personnel, all start-up operations were carried out smoothly and orderly, achieving one successful ignition, one successful impulse start, one successful test, and one successful grid connection after the unit maintenance.

    This A-maintenance achieved the set goals, which not only completely eliminated the defects in unit operation, but also accumulated valuable experience for unit maintenance. Next, Shenmu Calcium Carbide will continue to work hard to meet the "peak", do a good job in safety and environmental protection, production and operation, cost reduction and efficiency improvement, and go all out to win the "tough battle" to meet the peak and spend the summer.
