Foreign Waste Incinerator using Combustion Technology for Improving Power Generation

Abstract

Power generation from waste incineration is a more stable power source than other renewable energy forms and is also a dispersed power source that is connected to the power demand area. For these reasons, it is expected to become an effective solution to the problem of global warming. Since 2010, Japanese waste incineration plant companies have merged with European companies in order to promote progress in the global technical reorganization of this field.
　High efficiency power generation technologies used by European companies are little different from Japanese technologies. For example, use of low excess air ratio combustion, high temperature and high pressure steam conditions, adoption of water cooled steam condenser and installation of selective non-catalytic reduction. However, it is important to commercially benefit from waste management in Europe, so they actively work on recovery and supply of energy from waste and are operating many plants that have a steam condition of over 4MPa and over 400 deg C to supply not only power, but also heat as well.
