Tianyuan cogeneration project strides towards the goal of "double investment". The steam turbine of # 1 unit is successful for the first time.

"the steam engine turns!" On December 1, the commander-in-chief of the trial operation headquarters of Tianyuan cogeneration project department issued an order that the steam turbine of unit # 1 officially hung up and turned. 14:46:47, the steam turbine rushed smoothly to 3000r/min and successfully set the speed. The systems and equipment were operating normally, and all the parameters reached excellent and good values, which met the requirements of the technical specification. The task of turning the steam turbine for the first time was successfully completed, and warm applause and cheers broke out in the central control room.

Since the beginning of this year, with the joint efforts of the project department and the participating construction, supervision and debugging units, all kinds of work have been carried forward in a down-to-earth manner and good results have been reported frequently. In order to ensure the smooth progress of the transfer work of # 1 unit, the project department organizes an on-site morning meeting every day and holds a regular meeting every week to sort out and analyze and discuss various problems in time, work out a feasible rectification plan and promote the progress of the project. All levels of management, professional, construction personnel have a clear division of labor, perform their respective duties, stick to their posts in 24-hour shifts, and all work is in good order. Before the start-up of the unit, all the construction personnel cooperated closely, strictly implemented safety, organizational and technical measures, carried out a comprehensive and meticulous inspection of the commissioning equipment, organized personnel to make technical explanations, and strictly followed the requirements of various standards before flushing and transfer. strictly test and confirm the system parameters to ensure that the installation quality of the equipment meets the standard. The commissioning command has careful deployment and accurate command, comprehensively controls the key points, arranges each process scientifically and rationally, and strictly controls the transfer conditions to ensure the success of the transfer.

The steam turbine of # 1 unit was flushed successfully for the first time, and the quality of the design, equipment manufacturing, installation, commissioning and other plates were comprehensively tested. The smooth realization of this key node indicates that the unit is fully equipped with grid-connected conditions, and can successfully carry out the next stage of test work and grid-connected power generation, 168-hour full-load trial operation and commercial operation.

Thousands of miles of journey, faith is like Pan. The project department will continue to carry forward the spirit of overcoming difficulties and pragmatism, struggle against difficulties, move forward in the struggle, go all out to promote the progress of project construction, and strive to achieve the goal of "double investment" at an early date.
