| 20100119986 | MULTIPLE HEARTH FURNACE - A multiple hearth furnace includes a gas cooling system for its central shaft and its rabble arms. This gas cooling system includes within the shaft an annular main distribution channel for supplying a cooling gas to the rabble arms and a central exhaust channel for evacuating the cooling gas leaving the rabble arms. The gas cooling system further includes an annular main supply channel surrounding the annular main distribution channel and being outwardly delimited by an outer shell of the shaft. A cooling gas inlet is connected to the annular main supply channel. A cooling gas passage between the annular main supply channel and the annular main distribution channel is spaced from the cooling gas inlet, so that cooling gas supplied to the cooling gas inlet has to flow through the annular main supply channel through several hearth chambers before it flows through the cooling gas passage into the annular main distribution channel. | 05-13-2010 |

| 20150292802 | Carbon Baking Furnace - A carbon baking furnace has at least one vertical baking shaft with a system and method for positioning green carbon bodies to be baked at the top of the vertical baking path and ringing the green carbon bodies with a sacrificial medium such as packing coke. The disclosure provides a system and method for controlling the delivery and removal of the sacrificial medium used to surround the carbon bodies within the baking paths. A volatile extraction system and method are provided. A system and method for unloading baked carbon bodies is disclosed. | 10-15-2015 |
| 432098000 | Having agitator or movably mounted baffle for shaft or shaft outlet | 2 |
| 20090325115 | VERTICAL FURNACE FOR FABRICATION OF FINE ARTIFICIAL LIGHTWEIGHT AGGREGATES - The present invention relates to a vertical furnace for fabricating an artificially lightweight fine-aggregates in that the aggregate,; can he fired in the vertical furnace in a floating state, so that the contacting time between the aggregates can he minimized, thereby preventing the adhesion between the aggregates and manufacturing the artificially lightweight fine-aggregates as an insulating concrete for building material, sound-absorbing materials, and lagging material. The vertical furnace for fabricating artificially lightweight fine-aggregates comprises a vertical furnace having a raw material inlet; a ventilation fan for supplying a compressed air to the vertical furnace; an air regulating valve for regulating the supply of a main air supplied to the vertical furnace; an exhaust fan for discharging the artificially lightweight fine-aggregates of the vertical furnace to outside by discharging the main air supplied from the air regulating valve to outside of the vertical furnace; a heat exchanger for cooling the artificially lightweight fine-aggregates discharged from the vertical furnace; and a collecting device for collecting the artificially lightweight fine-aggregates cooled by the heat exchanger. | 12-31-2009 |
| 20140113241 | CALCINING KETTLE - A calcining kettle includes a cylindrical housing having a hot air chamber at one end, a dust collecting chamber at an opposite end and a calcining chamber between the hot air chamber and the dust collecting chamber, at least one air pad disposed between the hot air chamber and the calcining chamber, each air pad being supported by air pad supports for passage of hot air therethrough. At least one rake is disposed within the calcining chamber and configured for rotation about a vertical axis, the at least one rake stirring gypsum located adjacent to the at least one air pad. A plurality of burners is located within the calcining chamber and displaced from the air pad and the at least one rake in a direction toward the dust collecting chamber. The burners being disposed within a bed of gypsum that is heated by the burners for calcining the gypsum. | 04-24-2014 |
