Coal fired steam boiler design advantages:

1. The new type furnace arch strengthens the combustion, and the coal type has strong adaptability.

2. The convex tube plate reduces the thermal stress of the pipe end weld and eliminates the tension member to prevent the tube plate from cracking.

3. The wing shape flue arrangement, the flue gas three return , reduce the temperature of the high temperature tube sheet, thereby reducing damage to the boiler.

4. Threaded pipe, strengthen heat transfer, reduce the number of pipes, save steel, reduce the size of the shell, reduce the thermal stress at the end of the pipe, and prevent cracking of the pipe.
