Top Boilers Suppliers and Manufacturers in the USA
This problem is particular to negative pressure boiler schemes. Negative draft pulls ambient air (21%) oxygen into the process stream. For leaks around the process connection flange, the density of the cool ambient air makes it possible that the air "drafts" down the detector to the measurement cell resulting in erroneous oxygen measurement.
Note: 1 µg/L = 1 ppb. For complete oxygen removal down to low ppb levels a second step, chemical oxygen removal, is needed to assist the deaerator. It is important to monitor the actual DO level since air contains 21% oxygen and the difference between the atmospheric percent and ppb is a factor of 100,000,000. Thus, any
