摘要： In general, one embodiment of the invention is directed to food holding apparatus for holding pre-cooked food at a selected holding temperature. The apparatus comprises a cabinet having at least one holding compartment therein, and pre-cooked food in the holding compartment, the food having been previously cooked in a cooking appliance. At least one radiant heat source is spaced above the food a distance less than 12 inches (30.5 cm) for delivering radiant heat to the food. A control mechanism varies the amount of radiant heat delivered by the heat source to the food to maintain the food at the selected holding temperature. A related method is also disclosed.

摘要： A steel production facility and a method of uninterrupted, or at least cyclical, steelmaking in the facility. In the case of uninterrupted steelmaking at least the first three of the following steps and in case of cyclical steelmaking all five steps are performed: charge materials are molten uninterruptedly or cyclically in an electric arc furnace; the charge materials (e.g., shredded scrap-iron pieces shredded in a shredding-system for shredding discarded iron and/or steel junk), Direct Reduced Iron and/or Hot Briquette Iron are uninterruptedly or continuously during a melting process cycle fed into the electric arc furnace; a part of liquid steel is uninterruptedly or cyclically discharged from the steel bath of the electric arc furnace; from the thermic energy included in the hot process-exhaust of the electric arc furnace, electric energy is, by means of power generation, generated uninterruptedly or at least during a melting process cycle; a shredding-system assigned to the electric arc furnace for shredding the scrap is powered by the electric energy generated from the process exhaust.

摘要： Systems and methods for measuring the level of a plurality of phases of a conductive or semi-conductive mixture in a vessel. The systems and method include a vessel configured to hold the mixture, a plurality of antennas configured to transmit electromagnetic and/or eddy current signals into the mixture to impinge upon the plurality of phases and to receive corresponding signals reflected from the plurality of phases, a transmitter module configured to generate electromagnetic and/or eddy current signals in communication with the plurality of antennas, a receiver module configured to receive electromagnetic and/or eddy current signals in communication with the plurality of antennas, a control module in communication with the transmitter module and the receiver module configured to control their operation, and a signal analysis module in communication with the receiver module configured to process the reflected signals to determine the levels of the plurality of phases within the vessel.

摘要： Described is an apparatus (5) as well as a method for cooling kiln exhaust gases in a kiln bypass (7), which apparatus comprises a mixing chamber (9) for extracting and cooling a portion of the kiln exhaust gases from a kiln system (1, 3), said mixing chamber (9) comprising a tubular housing being provided at one end with an exhaust gas inlet (11) for kiln exhaust gases and provided at its other end with an outlet (13) for cooled exhaust gases, said mixing chamber (9) further comprising a tangential inlet (15) for cooling gases, where the apparatus also comprises a first fan (17) for supplying cooling gases to the mixing chamber (9) and a second fan (19) for drawing the kiln exhaust gases through the kiln bypass (7). The apparatus (5) and the method is peculiar in comprising means (31, 33) for measuring, respectively, the mass flow mA and the flow velocity vA of the cooling gases which are introduced to the mixing chamber (9), and the mass flow mB and the flow velocity vB of the cooled exhaust gases being discharged from the mixing chamber (9), a calculating unit (35) to determine on the basis of the measured values mA, vA, mB and vB the actual mass flow mC and the flow velocity vc for the kiln exhaust gases being drawn through the kiln bypass (7) and to compare the actual mass flow mC with a predetermined value for kiln exhaust gases targeted for being drawn through the kiln bypass (7), a calculating unit (35) to determine on the basis of the values mA, vA, mC and vC the actual swirl number S of the gases in the mixing chamber (9) and to compare this with a predetermined, desired value for the swirl number of the gases in the mixing chamber (9), and means (37, 39, 41) for regulating respectively the fan (17) for feeding cooling gases to the mixing chamber (9), the fan (19) for drawing the kiln exhaust gases through the kiln bypass (7) and the pressure loss across the apparatus (5) when &Dgr;mC or &Dgr;S deviates from 0. It is hereby obtained that, even subject to major variations in operating conditions, the quantity of kiln exhaust gases being drawn through the kiln bypass can be kept essentially constant while simultaneously ensuring sufficient cooling of the kiln exhaust gases in the mixing chamber, thereby preventing coatings from being formed in the mixing chamber per se as well as at its outlet and preventing entry of cooling gases into the kiln system as false air.

摘要： The invention relates to a ring furnace (1) having a longitudinal axis and comprising elongated bays (10), a plurality of hollow partitions (3, 3') arranged within the casing of each bay so as to be parallel to the longitudinal axis, a first end transverse wall (41) located at a first end of each bay (10), a second end transverse wall (42) located at a second end of each bay (10) and possibly one or more intermediate transverse walls (43) located between the first and second ends. The hollow partitions and transverse walls define baking pits (2) within the bays (10) for stacking carbonaceous articles therein. The baking pits have a length Lp and a width Wp, said length Lp being at least 15 times greater than said width Wp.
