The effect of major operating parameters in spray drying sorber(=SDS) for automatic control for the simultaneous removal of acidic and organic gaseous pollutants from solid waste incinerator was performed. The field experiment was carried out in pilot scale test for the quantification of major operating parameters of hydrophilic and the hydrophobic pollutants. The removal efficiencies of SO_2 and HCI in the 5wt% slurry condition were being increased with the increase of the stoichiometric ratio which is the molecular ratio of lime to the pollutant concentration, and with the decrease of inflow flue gas temperature in the pilot SDS reactor. The removal efficiency along the height of spray drying sorber was closely related to the temperature profile, and more than 90% of total removal efficiency was achieved in an absorption region. For the removal of acidic gas the optimum operating condition considering the economics and a stable operation is the 5wt% of slurry concentration, 1.2 of stoichiometric ratio and 250℃ of inflow flue gas temperature. For the organic gases of benzene and toluene the removal efficiencies were 20 - 60% which is much lower than that of acidic gas. The best removal efficiency was obtained at 1.5 of stoichiometric ratio and 250℃ of inflow flue gas temperature. The organic's removal efficiency along the height of spray drying sorber was quite different from that of acidic gas, that is, more than 60% of the total removal efficiency for benzene and 90% of the total removal for toluene were achieved in the dried adsorption region, which was formed at the lower or exit part of the reactor.

The purpose of this study was build the market place to connect with daily space through reconstruction of Yeongdeungpo Arcade Market. The Market constructed shops with no planning didn"t change with the stream of times, it brought slum to the market place. The roof was covered under the name of modernization, the market below roof is not different with old market occupied street by shops. This study plan to construct the market with autogenous local community by adding some program connected with daily space to the market street under the redevelopment issue.

It was evaluated whether carbonization would be available as a new technology for thermal treatment and recycle of municipal solid wastes(MSW) as alternative fuel. We studied on the fuel possibility of MSW by the carbonization. The yield was reduced as a carbonization temperature and time was increased and the contents of volatiles and the fixed carbons expressed the contrast tendency in all conditions. The fuel ratio were best suitable at the 500℃ of carbonization temperature and 30min of time. The calorific values of the carbonized products were in the range of 3,400~6,200㎉/㎏. The results of this research are illustrated that' the best condition for MSW carbonization is 500°C and 30min.
