| 201035000 | CARBONIZING UNDER PNEUMATIC PRESSURE OR VACUUM | 10 |
| 20100236914 | FLAT PUSH COKE WET QUENCHING APPARATUS AND PROCESS - A method and apparatus for quenching metallurgical coke made in a coking oven. The method includes pushing a unitary slab of incandescent coke onto a substantially planar receiving surface of an enclosed quenching car so that substantially all of the coke from the coking oven is pushed as a unitary slab onto the receiving surface of the quenching car. The slab of incandescent coke is quenched in an enclosed environment within the quenching car with a plurality of water quench nozzles while submerging at least a portion of the slab of incandescent coke by raising a water level in the quenching car. Subsequent to quenching the coke, the planar receiving surface is tilted to an angle sufficient to slide the quenched coke off of the planar receiving surface and onto a product collection conveyer and sufficient to drain water from the quenched coke. | 09-23-2010 |
| 20120055775 | PYROLYTIC PROCESS AND APPARATUS FOR PRODUCING BIOMASS CHAR AND ENERGY - A pyrolytic conversion assembly for processing biomass including: a rotary kiln including a tube for heating the biomass at pressure having a sealable inlet at a first, higher end for ingress of the biomass, and a sealable outlet at a lower end for egress of charcoal formed from the biomass; and heating elements disposed around the kiln to provide a localised source of heating at a predetermined distance from the sealable inlet for reflux condensation of gas from the biomass. | 03-08-2012 |
| 20120168297 | Biochar Process and Apparatus - A pyrolysis apparatus for processing carbon rich precursor feedstock into carbon rich biochar and associated carbon rich by-products includes a combustion chamber for high temperature low oxidative combustion of the feedstock having an inlet for the feedstock at a first end and outlet for the biochar at a second end; a heater to heat the combustion chamber; at least one gaseous outlet positioned between the first and second ends and communicating with an interior of the chamber, each of the gaseous outlets provided with an air venturi to control extraction of pyrolysis gas generated within the combustion chamber. | 07-05-2012 |
| 20120247939 | METHOD FOR GENERATING A NEGATIVE PRESSURE IN A COKE OVEN CHAMBER DURING THE DISCHARGING AND CHARGING PROCESSES - A method for extracting flue gases from a coke oven chamber, wherein the flue gases that develop briefly during the process of discharging and charging the coke cake from and to the coke oven chamber are extracted by a vacuum generated in the headspace above the coke cake. The vacuum in the headspace above the coke oven chamber is generated via channels through the lateral walls of the coke oven chamber or in the coke cake. The vacuum is generated in the secondary heating chamber and, by way of example, can be extracted again from a vacuum supply tank which, for the time that the coke oven chamber doors are open, is connected to the secondary heating chamber by opening shut-off devices in the connecting line. The method avoids the undesirable emission of flue gases into the atmosphere. A device whereby the method can be carried out is also disclosed. | 10-04-2012 |
| 20130213791 | Coking Plant and Method for Controlling said Plant - The present invention provides a coking plant. The coking plant includes a series of coke ovens, each oven including a coking chamber provided with side unloading doors. The chamber communicates with a riser provided with a coking-gas discharge pipe. The discharge pipes of each oven lead into a collecting cylinder, which is in turn connected to a coking gas treatment circuit. At least one discharge pipe of one of the ovens further includes a device for spraying pressurized liquid onto the wall of the discharge pipe. The liquid flows counter-current with respect to the direction of the flow of the gases exiting the chamber. The present invention also provides a method for controlling such a plant. | 08-22-2013 |
| 20140054157 | DEVICE AND METHOD FOR REGULATING THE CHAMBER PRESSURE OF COKING CHAMBERS OF A COKE-OVEN BATTERY USING ADJUSTABLE DIAPHRAGMS AT THE ASCENDING PIPE ELBOW OPENINGS INTO THE RAW GAS RECEIVERS - A device for regulating the chamber pressure of coking chambers of a coke-oven battery using adjustable iris diaphragms or iris nozzles at the ascending pipe elbow openings in the raw gas receiver. The gas stream flowing from the gas chamber of a coking chamber into the raw gas receiver can thus be regulated so that the pressure in the gas chamber of the coking chamber can be controlled. A method is also disclosed for regulating the gas stream which flows out the gas chamber of a coking chamber, wherein the pressure in the coking chamber is regulated by the control, and wherein also the liquid stream is regulated which serves to wash out the coking gases from the raw gas stream of the coking chamber. | 02-27-2014 |
| 20140124354 | HIGH TEMPERATURE THERMAL MODIFICATION PROCESS OF WOOD IN A VACUUM AUTOCLAVE - A process for the thermal-chemical modification treatment of wood is described, in which such a modification is obtained through multiple chemical reactions of the substances comprising the wood structure generated by exposing the wood to temperatures at which the pyrolysis phenomenon begins, i.e., in the range of 180° C.-240° C., in a vacuum autoclave-cell while always maintaining the internal pressure lower than the atmospheric pressure, in a range of values of 70-350 mBar of absolute pressure, consisting in the steps of pre-heating, actual heat treatment, and cooling of a wood mass. | 05-08-2014 |
| 20150337205 | DEVICE AND METHOD FOR REGULATING AND CONTROLLING THE GAS PRESSURE - A device and a method are provided for regulating and controlling individual gas pressure of individual ovens of a coke oven battery, in the case of which a rising-pipe bend projects, preferably from above, into a collecting main. The lower end thereof is associated with an immersion pipe via a water labyrinth seal. The immersion pipe is supported such that it is vertically adjustable by means of an actuator, and an immersion cup is located preferably below the immersion pipe. The rising-pipe bend has arranged therein a sleeve, the lower end of which is connected via at least one conduit to the water labyrinth seal. A water supply for feeding the water labyrinth seal and the actuator are provided at the top, outside the rising-pipe bend. Regulation of the gas pressure is accomplished by different immersion depths of the immersion pipe and the constant water level in the immersion cup. | 11-26-2015 |
