1. Check that the outlet water temperature, return water temperature, and pressure of the Shaanxi steam generator are normal and stable, and that combustion is good;

2. Check that the feed pump and standby pump are functioning properly;

3. Check that the pressure gauge, thermometer, and flow meter are undamaged;

4. Perform testing and treatment of the Shaanxi steam generator water quality, requiring that the makeup water has suspended solids≤20mg/h, total hardness≤216mg/h,pH(25℃)≥1, oil content≤2mg/h,and circulating waterpH=10~12;

5. Open the blowdown valve at regular intervals daily to discharge scale from the boiler.

6. The boiler should be shut down immediately under the following circumstances:

(1) When the outlet water temperature rises sharply and the difference from the corresponding saturation temperature under operating pressure is less than 20°C, or when vaporization has been detected;

When both the circulating water pump and the feed pump fail;

(2) When the pressure gauge, thermometer, and safety valve all fail;

(3) When components of the Shaanxi steam generator are damaged and pose a risk to operating personnel;

(4) When the feed pump continuously supplies water to the boiler, but the boiler pressure continues to drop;

(5) When a heating surface bursts and the outlet pressure cannot be maintained;

(6) When gas continues to be supplied after the boiler flame is extinguished.
