Abstract:Due to large deaerator makeup water requires, large heat steam consumption, high cost and wasting residue water while maintenance, technology improvement has been done. The utilization of communicating vessel was proposed. Method to reduce waste of deaerator tank residue water before maintenance was indicated. Which will effectively reduce deaerator operational cost. At the same time, production cost will be reduced, and realized energy saving and cost decreasing and benefit increasing.

Keywords:parallel, deaerator, communicating vessels, energy saving
