What is the draft condition recommended when using soot blowers?

The recommended draft condition when using soot blowers is between -0.10 to -0.15 inches of water. This range is vital for ensuring the effective removal of soot and debris from boiler tubes without adversely affecting the combustion process or boiler operation. Maintaining this optimal draft condition helps in achieving the necessary pressure differential for soot blowers to operate effectively, thereby enhancing the efficiency of heat transfer and preventing potential damage due to excessive build-up.

Operating outside this draft range could lead to insufficient cleaning, or conversely, too aggressive cleaning that can disrupt normal combustion and boiler performance. Therefore, staying within this specific draft range aligns with best practices for boiler maintenance and operation, ensuring both safety and efficiency.
