1. Before trial production, the waste heat power generation operator should obtain the corresponding qualification certificate (pressure vessel operation certificate), use four shifts and three operations, each value has 4 employees (2 operators, 2 inspection workers), the whole system has 1 full-time water technician; the system adopts the principle of centralized control in the central control room and field priority. The operator should be familiar with the process, not only to control the equipment and adjust the operating parameters on the computer screen, but also to know the current screen production status How does it correspond to the actual situation on site? Know how to use the information given on the screen to determine the operating status of each equipment. When there is an abnormality, the operation is fast and accurate; the inspector should have a clear process flow, have received on-site safety education, and have certain equipment maintenance experience.


2. Before trial production, prepare boiler operation regulations, steam turbine operation regulations, generator operation regulations, central control room operation regulations, and safe operation regulations.


3. Before trial production, on-site equipment should be sanitary, safety equipment should be complete, inspection tools and common maintenance tools should be well prepared.


4. The values of field instruments and meters are consistent with those of the central control. All control and interlocking relationships meet the technological requirements. The emergency shutdown and interlocking are accurate and reliable. The PC system indicates the point of failure and the alarm signal is reliable.


V. Required conditions: All electrical equipment installation work has been completed and passed the experience; all electrical tests (static) work have been completed; relay protection, electrical instrumentation and automatic device verification work has been completed, confirmed by transmission test The operating conditions are normal; the boilers and steam turbine parts are ready for operation.


6. Before trial production, the softened water system can be used normally, the installation unit has cooked the AQC and SP boilers, all safety valves have been adjusted and checked, the main steam pipeline has been flushed, and the circulating pool pipeline system has been cleaned and pre-cleaned. After the membrane is completed, the circulation tank is filled with water.


7. Before production, the grid-connected license has been obtained from the power supply department.
