DECREASE IN CO2 EMISSION BY USING BIOMASS BRIQUETTE AS A COKE SUBSTITUTE AT HIGH-TEMPERATURE GASIFYING AND DIRECT MELTING FURNACE

摘要

The high-temperature gasifying and direct melting furnace simultaneously gasifies wastes and melts the ash using coke, and is capable of treating diverse types of waste, beginning with municipal solid waste (MSW) and also including industrial waste, incineration ash, excavated landfill waste, asbestos, etc. The authors have supplied 10 waste treatment plants employing this unique technology since construction of the first unit was completed in 2003. In response to heightened social demand for reduction of CO2 emissions in recent years, the authors have actively studied methods of reducing CO2 emissions by reducing coke consumption.
