In order to surely discharge dust produced in a sample containing part 10, the present invention is adapted to include: a dust introduction part 30 that has a through-hole 3a formed penetrating in a vertical direction and introduces dust produced in the sample containing part 10 into the through-hole 3a; a dust containing part 43 that contains the dust discharged through the through-hole 3a; and a dust discharge path 41a of which one end is connected to the dust introduction part 30 to communicatively connect to the through-hole 3a and the other end is connected to the dust containing part 43, in which the dust discharge path 41a is linearly formed along the vertical direction from the one end to the other end.

The present disclosure is related to a method of producing a fired ceramic article. The method may include: heating a ceramic green body in a kiln, and controlling oxygen concentration in the kiln such that the oxygen concentration swings during the heating of the ceramic green body.

A materials processing furnace provides for debinding and sintering objects and treating effluent generated by the sintering. A heating chamber maintains a controlled atmosphere for sintering the object. A vacuum pump evacuates an effluent from the heating chamber, and an injector adds a reagent to the evacuated effluent to form a mixed gas. A catalytic converter receives the mixed gas and catalyzes one or more hazardous or offensive compounds of the effluent, thereby converting the effluent to a safer and less offensive exhaust. As a result, the furnace is suitable for operation in an office environment.

Automatically generating a compensation factor for adjusting an operating parameter such that a measured carbon potential, dew point, or other controlled parameter matches the controller's set point value by inputting the measured parameter directly to the controller.

The invention relates to an aluminum scrap melting system (1) comprising a melting furnace (10) comprising a burner (20) which comprises an oxidant injector (23), and a fuel injector (25); a suction hood (30) intended to capture by suction the combustion fumes (F) and comprising a carbon monoxide sensor (37) configured to measure a carbon monoxide concentration (C) in said combustion fumes (F); and a control device (50) configured to receive an item of input information representative of the value of the carbon monoxide concentration (C), and to pilot the oxidant injector (23) and/or the fuel injector (25), according to said item of input information, the oxidant and fuel flows being piloted to contain the volatile organic compound content (VOC) at the output of the melting furnace at concentrations less than a safety value. The invention also relates to a process for melting aluminum scrap with such a melting system (1).
