Due to the failure of the air preheater of the #5 furnace of Shaoxing Binhai Thermal Power Plant on April 9, it continued to operate with the defect for 13 days. Now it is found that the failure has worsened, and it is urgent to shut down the furnace for repairs. During the repair period, there will be a certain gap in the steam supply in the gathering area. In order to ensure the safety of the heating network and the stable production of all printing and dyeing users, Zhejiang ** Shaoxing Binhai Thermal Power Co., Ltd. (hereinafter referred to as ** Thermal Power) and Zhejiang ** Environmental Protection Thermal Power Co., Ltd. (hereinafter referred to as ** Environmental Protection) decided based on the current operating status of the heating network. Activate this emergency plan. See the details.
1. Plan timeliness
1. Emergency plan activation time: 20:00 pm on April 21, 2021
2. End time of emergency plan: The emergency repair time is estimated to be 7 days. The end time of this emergency plan will be when the operating pressure of the heating network is normal. **Heating and **Environmental Protection will notify all users in advance.
II. Specific measures
1. Steam suspension objects: 57 printing and dyeing enterprises in the agglomeration area, divided into 10 groups (each group has a steam demand of about 300 /h) For details, please refer to the “Organized Steam Usage Grouping and Usage Balance Table”.
2. Steam shutdown types: low and medium pressure steam.
3. Steam stop method: Taking into account the objective implementation of orderly steam use in the past, this orderly use of steam will be carried out by closing the branch valves of the heating network pipelines. At the same time, in order to ensure the heat The network operation is safe, and the order of steam shutdown is fixed from the first group to the tenth group.
Emergency plan
It is reported that, The thermal power company will comprehensively balance the operation of the heating network. This round of orderly steam use will temporarily arrange the rotation stop sequence with a steam gap of 300/h, that is, one group of rotations every day. If the operating pressure of the heating network is still not ideal after the first day of rotation, it will be considered The situation increases and the user is suspended. </p
