Save Energy by Helper Turbine Redesigning The Drive System of Boiler Feed Water Pump

摘要

To corresupond to the increasing of the demand for recycled paper, we installed de-inked pulp plant at Komatsushima Mill, Nippon Paper Industries Co., Ltd. As the result, the quanlitiy of consumed electric power was getting increased, and we putchased more electricity from an electric power company.Then we installed a helper turbine on boiler water pump as a part of our energy-saving project. As a result of this, we correct steam energy at reduced pressure as driven energy of water feed pump.
