摘要： PROBLEM TO BE SOLVED: To equalize the descending speeds of charged materials in a cross-sectional plane in a furnace to minimize inferior heat exchange by a method wherein when temperatures in the furnace sensed by thermometers, which are provided in such a manner that a plurality of thermometers are provided in a cross-sectional direction of a shaft part and in a plurality of stages in the vertical direction of the shaft part, exceed specified values, the quantity of air blown in from an upper stage tuyere is reduced. SOLUTION: In order to sense a descent and cavity of charged materials in a cross-sectional direction, a plurality of thermometers 5 are provided in a spaced apart relationship in a cross-sectional direction of a shaft part 1a and in a plurality of stages in the vertical direction thereof to measure temperatures of gas and solids in a melting furnace. When a thermometer 5a indicates a value exceeding a specified value, a judgment is made that heat is not sufficiently exchanged between solids and gas and charged materials are not normally descending, and hence the quantity of air blown in from an upper stage tuyere 3a is reduced by means of a shutoff valve 4a. When thermometers 5a-5d in some stage indicate a value lower than the specified value, a judgement is made that the thermometers 5a-5d sense temperatures of solids and hence there exist solids and the charged materials are descending normally, and hence the shutoff valves 4a-4d are kept open and predetermined amount of air is blown in.

摘要： PURPOSE:To prevent generation of a trouble of fusing of ash component and to relize a stable operation in a treatment of combustible waste by using a thermal cracking furnace. CONSTITUTION:When combustible waste is thermally cracked by a thermal cracking furnace and a thermally cracked remain is afterburned in an afterburning chamber 6, a part connecting a generated gas outlet space of the thermal cracking furnace and a space for afterburning of the thermally cracked remain is given gas flow resistance by a thermally cracked remain filled layer 20 or a breaking valve 27, so that gases in the both spaces can be prevented from mixing with each other. A recombusting chamber 5 to burn gas generated in the course of the thermal cracking and the after-burning chamber 6 to afterburn the remain are arranged in the same furnace space. In addition, the thermal cracking furnace and the afterburning chamber 6 are connected through a remain transfer conveyor 21 to keep heat held by the remain as much as possible and to promote ashing.

摘要： PROBLEM TO BE SOLVED: To provide a method and an apparatus for cleaning gasified gas, by which the adsorption capacity is effectively recovered and a maintaining gas-cleaning performance of the apparatus is achieved, even when the adsorption capacity is decreased by adsorbing high-boiling hydrocarbon compounds in gasified gas. SOLUTION: A gasified gas obtained by thermally decomposing organic waste or solid organic matter such as coal is cooled to a temperature of 60°C or lower to remove water mist, tar components of a liquid hydrocarbon, and solid dusts included in the cooled gasified gas, before the gas is passed through activated carbon adsorption device 1 composed of activated carbon adsorption columns 1a and 1b. The cooled gasified gas is then heated, and passed through the activated carbon adsorption device 1. Feed of the gasified gas is interrupted and steam is fed to those adsorption columns the adsorption capacity of which is decreased due to the adsorption of high-boiling hydrocarbon compounds to release the high-boiling hydrocarbon compounds. The released high-boiling hydrocarbon compounds are discharged to the steam side as waste steam. After the adsorption capacity is restored, feed of the gasified gas is resumed.
