Countering Global Warming: Carbon Dioxide Reduction Measures at Yamaha's Kakegawa Factory
- Boiler Fuel Conversion and Installation of a Cogeneration System
Together with the installation of a cogeneration system at its Kakegawa Factory, Yamaha Corporation updated its fuel oil fired (run) boilers to an LNG boiler that runs on natural gas. This new boiler system began operating on February 22 of this year.
These changes will allow a reduction in primary energy use from the previous year's figures. This reduction will be equivalent to approximately 420 thousand liters of crude oil, and drop CO2 output by around 2,900 tons per year.
This system operates on two natural-gas fuelled motors generating 1,260kW each, and utilizes the heat emitted by this equipment to create steam and hot water for use in air conditioning and piano manufacturing processes within the factory.
In conjunction with this update, the nine fuel-oil fired boilers used for factory air conditioning and to provide heat for piano manufacturing processes (three of which were brought and reused from the headquarters factory), were switched to boilers running on natural gas. LNG generates more energy per unit than fuel oil and releases less carbon dioxide, allowing installations to generate the same amount of energy as previous equipment while reducing their output of carbon dioxide.
Moreover, LNG contains no sulfur, allowing for sulfur oxide emissions to be curbed. Yamaha Corporation and its Group Companies join Japan in its goal of reducing carbon dioxide output in 2010 by six percent from 1990 levels, in accordance with the Kyoto protocols ratified by the nation.
The reduction in carbon dioxide emissions achieved through these measures equate to 2.9 percent of the total emissions of Yamaha Group manufacturing operations, making a significant contribution towards achieving this goal.
