| 20080280244 | METHOD OF DISCHARGING GAS FROM CONTINUOUS OVEN AND GAS DISCHARGE STRUCTURE - A to-be-burned object including a metal Si component or SiC or Si | 11-13-2008 |
| 20090136886 | Method and Device for Removing Volatile Organic Components From Waste Gases of a Clinker Installation - In a method for removing volatile organic components (VOC) from waste gases of a cement clinker kilns installation, in which the largely cooled waste gases are subjected to post-combustion, a post-combustion is carried out to an extent as to ensure a reduction of the concentration of the VOC below the admissible threshold values. The post-combustion is carried out for the production of vapour, whereby the production of vapour in the post-combustion is dimensioned for a gas volume to be post-combusted, ensuring that a partial quantity of the waste gas corresponding to the gas volume allows for the reduction of emitted VOC per unit time in the waste gas below admissible concentration values by rarefaction and whereby this partial quantity is simultaneously dimensioned for the production of a amount of vapour sufficient for the economical operation of a given steam turbine. The device for carrying out said method is characterized in that a branch line is connected to the waste gas line of the cement clinker kiln installation, between the pre-calciner and the waste gas suction fan, to which branch line a combustion chamber for a heat exchanger for the production of vapour and a steam turbine are connected. The invention also relates to a device for carrying out said method, characterised in that a branch line is connected to the waste gas line of the clinker installation, between a preheater and the waste gas suction fan, a combustion chamber for a heat exchanger for producing water vapour and a steam turbine being connected to said branch line. | 05-28-2009 |
| 20140045131 | SPRAY DRYING APPARATUS FOR DEHYDRATED FILTRATE FROM DESULFURIZATION WASTE WATER, AND AIR POLLUTION CONTROL SYSTEM - A spray drying apparatus includes: a gas inlet provided in a side wall in the vicinity of a top (lid) portion of the spray drying apparatus, for introducing a flue gas for drying a spray of dehydrated filtrate; flow-adjusting plates provided in a body of the spray drying apparatus, for decelerating the introduced flue gas so as to change the flow of the flue gas to a laminar flow; a spray nozzle for spraying the dehydrated filtrate from the desulfurization waste water into the flue gas having been changed to the laminar flow; and a joining unit for joining a bottom portion of the body of the spray drying apparatus to a gas supply line that is a main flue gas duct for the flue gas so as to discharge spray-dried solids to the main flue gas duct. | 02-13-2014 |
| 20140057221 | SYSTEM FOR THE THERMAL PREPARATION OF RECLAIMED ROAD MATERIAL CONTAINING PAHS OR OIL SLUDGE - A system for the thermal preparation of reclaimed road material containing PAHs, or of oil sludge having a loading station for pre-comminuted reclaimed road material or oil sludge, a rotary kiln in which the reclaimed road material or the oil sludge is burned, while oxidation air is fed in, a dust separator to which the flue gases produced in the rotary kiln are fed, an after-burner to which the flue gases leaving the dust separator are fed, and a filter to which the flue gases arising in the after-burning means are fed. These components are divided into a plurality of modules, each of which includes a weight and dimension such that each may individually be transported using conventional road transport means, in particular low loaders or heavy goods vehicles. | 02-27-2014 |
| 20140120486 | CEMENT PLANT - There is provided a cement plant including a chlorine bypass apparatus capable of efficiently reducing the chlorine concentration in a cement kiln due to exhaust gas extraction by a small amount, by preventing calciner exhaust gas low in chlorine concentration from contamination and extracting a part of kiln exhaust gas high in chlorine concentration. In the invention, a baffle wall | 05-01-2014 |
| 20150037745 | DEVICE AND SYSTEM FOR PRODUCING CEMENT CLINKER - In the method according to the invention for producing cement clinker, raw cement meal is preheated in a preheater, the preheated raw cement meal is precalcined in a calciner and the precalcined raw cement meal is burnt in a kiln, fuel and combustion air having an oxygen content of at least 75 mol % being used in the calciner, and the raw cement meal being precalcined in a fluidised bed in the calciner. The exhaust gases occurring in the kiln are delivered to the preheater, bypassing the calciner, and the exhaust gases of the calciner are delivered to a CO | 02-05-2015 |
| 20160052048 | Furnace Assembly - A furnace assembly for dewaxing investment casting molds includes a housing having a top and a bottom and sides and extends along an axis to define a cavity. A plurality of tiles are supported in a spaced relationship with the bottom of the housing and define a pair of lower chambers for directing the wax vapors out of the cavity. A plurality of trays having apertures are supported by the tiles for moving molds through the housing. Chimneys connect to the lower chambers and a passageway is defined by the tiles for evacuating the wax and wax vapors from the cavity to the lower chambers and out through the chimneys. A pair of lower burners extends into the lower chambers for igniting wax vapors in said lower chambers. The heat from the lower chambers radiantly heats up portions of the furnace assembly that are disposed above the lower chambers. | 02-25-2016 |
