Reduction Electricity Cost by Enhancing the Capacity of TMP Plant

Abstract

For remarkable rise of crude oil price, Chuetsu Pulp & Paper Futatsuka mill stopped an expensive dust coal boiler of the generation unit price in June 2010, and shifted to running only by a biomass boiler. As a result, the self-generation of electricity of Futatsuka mill is used up with facilities except thermomechanical pulp (TMP) plant. Thus, it was necessary to use purchase electricity for the operation of TMP plant which needed much electricity. For ability of storage and production capacity, Futatsuka mill couldn't but operate TMP plant in daytime since the unit price of purchase electricity was higher on weekdays.
In this report, we would like to introduce the case study that could increase the capacity of production as well as energy and cost saving significantly have achieved with making use of the equipment that has so far remained unused.
