  • The Feedtank and Feedwater Conditioning

    The boiler undergoes thermal shock when cold water is introduced to the hot surfaces of the boiler wall and its tubes. Hotter feedwater means a lower temperature difference and less risk of thermal shock. To maintain the designed output. The lower the boiler feedwater temperature, the more heat is required in the boiler to produce steam.
