摘要： A waste-feeding method by a waste-feeding apparatus. The waste-feeding apparatus includes a vertical chute including upper and lower dampers separated from one another by a predetermined distance in an up-down direction, the upper and lower dampers having a sealing function that inhibits external air from entering a gasifier and configured to be alternately opened and closed, and a waste-conveying device configured to convey waste, which has been fed through the vertical chute, toward the gasifier. The waste-feeding method comprises the steps of: if a damper-closed signal is not received although an upper cylinder, which opens and closes the upper damper, has been operated to close the upper damper, determining that the waste is caught by the upper damper, and temporarily stopping feeding of the waste to the vertical chute; during the stop of the feeding of the waste, opening the upper damper to remove the caught waste, and closing the open upper damper; and if the damper-closed signal is received, determining that the waste caught by the upper damper has been removed, and starting the feeding of the waste to the vertical chute.

摘要： [PROBLEMS] 1. To realize high-efficiency operation of a gasification-melting furnace by rest of an auxiliary burner while avoiding abnormal combustion of unburned gas in reignition of the auxiliary burner. 2. To facilitate a proper adjustment of the basicity without a special analyzer for a slag composition in operation of a gasification-melting furnace.
[MEANS TO SOLVE PROBLEMS] 1. The burner in the gasification-melting furnace is stopped when operation state thereof satisfies a specific condition. Thereafter, at a point in time when the temperature in the vicinity of the burner is lowered to a predetermined temperature, the supply of a waste material from a dust feeder to the gasification furnace is stopped. After this increases the concentration of oxygen in gas in outlet of the gasification furnace, the burner is reignited. 2. The basicity of slag discharged form a slag-discharge port in the melting furnace is adjusted by supply of a basicity adjuster from a basicity adjuster supplying apparatus. To determine an amount of the supply, utilized is a correlation between a parameter corresponding to the calorific value of the waste material per unit weight and the slag basicity.

摘要： A waste treatment system is provided with a melting furnace (200) for melting ash that is included in combustible gas, a denitrification agent supply unit (300) for supplying a denitrification agent that reduces NOx, and a control unit (400) for controlling the amount of the denitrification agent that is supplied. The melting furnace (200) includes a primary combustion chamber (210) having an inlet port and a secondary combustion chamber (220). The control unit (400) calculates an estimation value of concentration of NOx produced in the melting furnace (200) based on the temperature in a correlation region (S) at or near the inlet port of the primary combustion chamber (210) and an air ratio, where the correlation between the temperature and NOx concentration in the correlation region (S) is stronger than that in the secondary combustion chamber (220). The control unit (400) controls the amount of the denitrification agent to be supplied by the denitrification agent supply unit (300) based on the estimation value.
