Guide: These tasks include: (1) Water pressure test (overpressure test), checking the tightness of pressure-bearing parts (2) Auxiliary machine test run and verification of electric doors and dampers. (3) Oven. Remove the moisture on the furnace wall and the water accumulated in the boiler tube.

These tasks include:

　　(1) Water pressure test (overpressure test), to check the tightness of pressure-bearing parts.

　　(2) Auxiliary engine test run and verification of electric doors and dampers.

　　(3) Oven. Remove the moisture on the furnace wall and the water accumulated in the boiler tube.

　　(4) Stove and pickling. Use lye and acid to remove grease, rust, oxide scale and other corrosion products and scale deposits on the heating surface of the evaporation system.

　　(5) Furnace aerodynamic field test.

　　(6) Flush the tube. Use the boiler's self-generated steam to flush out the slag in the primary and secondary steam pipelines.

　　(7) Check the safety door, etc.
