Precise and consistent chemical metering

Blacoh Fluid Control was approached by the GM of a 300 megawatt power plant that used a chemical feed system to delivery hydrazine to a boiler: precise and consistent quantity delivery was needed

Blacoh Fluid Control was approached by the GM of a 300 megawatt power plant that used a chemical feed system to delivery hydrazine to a boiler.

The hydrazine was used as an "oxygen scavenger", and it was essential that it be delivered in a precise and consistent quantity.

While the metering pumps they used could deliver the hydrazine in precise amounts, their reciprocating action would not allow the delivery to be in a smooth and consistent flow.

To remedy the situation, Blacoh Fluid Control installed a Sentry III Pulsation Dampener in the common discharge of the two metering pumps to create smooth and consistent flow.

Since installation, the hydrazine is now delivered to the boiler in a precise and consistent quantity.

In addition, pipe vibration has been eliminated, gauge accuracy has been maximised, and pump component stress has been reduced.
