Title:

WASTE-MELTING METHOD

Document Type and Number:

WIPO Patent Application WO/2012/161203

Kind Code:

A1

Abstract:

The invention addresses the problem of providing a waste-melting method, with which the amount of coal coke used in a vertical-type waste-melting furnace is reduced to reduce the emission of carbon dioxide and also to enable the suppression of an increase in the running costs of the waste-melting furnace, and also the heat of combustion of volatile matter contained in a biomass starting material can be effectively utilized, and more stable operation can be achieved. A waste-melting method, in which waste is fed into a waste-melting furnace (1), and the waste is thermally decomposed and combusted, and then, thermal decomposition and combustion residues are melted, is characterized in that coal coke and a biomass-molded material obtained by press-molding a biomass starting material while heating the biomass starting material to a temperature lower than the carbonization temperature thereof are fed into the melting furnace, a high-temperature grate is formed with coal coke at the bottom of the melting furnace, and the coal coke and the biomass-molded material are combusted and used as heat sources for melting.
