Operational experience of the recycle boiler

Abstract

From the point of view of the global warming and the cost performance of the fuel, the fuel conversion, from the fossil fuel to the biomass, has recently been prompted among the pulp and paper industry in Japan. Because the fuel conversion had been one of the most important problems in Hachinohe mill for years, we decided to install the waste boiler that used waste tires, waste wood and paper sludge as fuel, At last we started the commercial operation of the waste boiler in July 2004. Since then, the boiler has been working well. As a result of the operation of this waste boiler, we were able to reduce not only the energy cost but also the amount of the CO2 discharge.
