Worldwide trend of waste treatment technology is rapidly transferring from "incineration system" to "gasification & melting system" which can derive the resources from waste and charge no more environmental burden to nature. And therefore it is necessary for our country to adopt gasification & melting system urgently to present the land pollution and lack of landfill area. Among several gasification and melting processes Daewoo-Thermoselect gasification and melting system is the representative process which can transfer waste to resources such as sin-gas, molten slag, metal hydroxide, mixed salt and sulfur through the process of compaction, degasification, gasification and melting.

Social interest and request about low pollution waste treatment process are growing and gasification melting method, as a new technology concept, is risen. The necessity of engineering analysis to determine design standards and operation condition is required. In this study, the objective and function of components and operation process of various gasification melting furnaces such as shaft type, fluidized bed and Rotary Kiln type gasification melting furnace are reviewed and the design standard and operation range of gasification melting furnace are determined by inspecting the change of output and operation condition with input condition change.

Gasification has been regarded as a very important technology to decrease environmental pollution and to obtain higher efficiency. The gasification process converts carbon containing feedstock into a synthesis gas, composed primarily of CO and $H_2$. And the synthesis gas can be used as a source for power generation or chemical material production. Through more than nine years, IAE developed and upgraded several gasification/melting pilot plant system, and obtained a good quality synthesis gas. This paper illustrates the gasification characteristics and operation results of two 3 ton/day synthesis gas production facilities. One is entrained-bed slagging type coal gasifier system which is normally operated in the temperature range of $1,400\~1,450^{\circ}C,\;8\~10$ bar pressure. And the other is fixed-bed type gasification/melting furnace system using MSW and industrial wastes as a feedstock.

The 3 ton/day-scale pilot plant consists of compressor, feed channel, fixed bed type gasification & melting furnace, quench scrubber, demister, flare stack and gas engine. Syngas composition of gasification using the 35.50(waste I), 4.34%(wasteII) moisture-containing solid waste showed waste I CO 25-35%, 20-40% hydrogen, waste II 25-35%, 20-30% hydrogen. Gasification melting furnace was operated $1,500{\sim}1,600^{\cdot}C$. Gas engine was generated $35{\sim}40$ kW as waste gasification syngas.

Automobile Shredder Residue (ASR) is very appropriate in a gasification melting system. Gasification melting system, because of high reaction temperature over than $1,350^{\circ}C$, can reduce harmful materials. To use the gasification processes for hydrogen production, the high concentration of CO in syngas must be converted into hydrogen gas by using water gas shift reaction. In this study, the characteristics of shift reaction of the high temperature catalyst (KATALCO 71-5M) and the low temperature catalyst (KATALCO 83-3X) in the fixed - bed reactor has been determined by using simulation gas which is equal with the syngas composition of gasification melting process. The carbon monoxide composition has been decreased as the WGS reaction temperature has increased. And the occurrence quantity of the hydrogen and the carbon dioxide increased. When using the high temperature catalyst, the carbon monoxide conversion ratio ($1-CO_{out}/CO_{in}$) rose up to 95.8 from 55.6. Compared with average conversion ratio from the identical synthesis gas composition, the low temperature catalyst was better than the high temperature catalyst.

Gasification and melting method is one of the most potential means for waste treatment process with low emission of fly ash or heavy metal, dioxin and high possibility of using slags as resources. Moisture contents influences directly a gasification characteristics of waste. So it is necessary to investigate the effect of moisture contents in gasification. But it is hard to consider the effect of moisture contents, using samples of powder form of Milligram's order in existing thermogravimetric analyser. Therefore, we made a thermogravimetric analysis device to applicate samples of Gram's order. Gasification characteristics are typically reported with result from thermogravimetric analysis date for wood and RDF samples along with changing moisture contents. It is discussed the way to apply these analysis results to gasification and melting furnace.
