Introduction and Operating Experience of the No. 2 Gas Turbine Plant

Abstract

We run the mill emphasizing the environment, based on the company's corporate philosophy.
We have improved CO₂ emission intensities with continued activities of saving energy on power plant sections, introductions of large scale Soda Recovery Boiler and Biomass Boiler utilizing fuel wood, fuel source of existing boiler and turbine have been changed to natural gas. We have also experienced violent fluctuations of energy prices around the failure of Lehman Brothers and felt the necessity of diversification of energy source caused by the Great Japan East Earthquake. Against such a background, we planned to introduce the 40 MW class Gas Turbine divertible of aircraft engine, as renewing the existing outdated Oil Boiler, 18 MW-class Steam Turbine and 17 MW-class Gas Turbine.
No. 2 Gas Turbine plant has started business operation since March 2014. Thereafter, Fuel intensities converted into crude oil equivalent and CO₂ emission intensities have been improving. In this paper, we briefly describe the outline of the equipment and operating experience of No. 2 Gas Turbine plant.
