| 20110150625 | METHOD OF COAL DELIVERY TO A HEAT POWER PLANT FOR COMBUSTION - The invention relates to the transportation and preparation for combustion of coal used as a solid fuel at heat power plants and can find applications in coal-based power generation. The object of the invention is a complex use of energy resources contained in coal, reduction of power consumption for the realization of the process, expansion of solid fuel pipeline transport application in coal-based power generation, increase in the coal pipeline operation safety, and the environment protection. Prior to the transportation via a pipeline, the initial stream of coal is screened into coarse material and fines, the latter being pressed into cylindrical monolithic blocks. Coal is transported via a pipeline filled with aqueous salt solution with a density exceeding that of the transported material, the coarse coal and pressed blocks being loaded into the pipeline alternately. At the power station, the coal delivered in the aqueous salt solution is separated from the liquid carrier, rinsed with water, dried and ground with simultaneous capturing of released methane. The effluents of rinsing are evaporated by heat released at the condensation of the working medium of the power plant thermodynamic cycle. The remaining stripped solution is mixed with liquid medium separated from the coal and returned to the starting point of the process. | 06-23-2011 |
| 20110311346 | METHOD AND SYSTEM FOR ADJUSTING THE FLOW RATE OF CHARGE MATERIAL IN A CHARGING PROCESS OF A SHAFT FURNACE - In a charging process of a shaft furnace, in particular of a blast furnace, batches of charge material are typically discharged in cyclical sequence into the furnace from a top hopper using a flow control valve. A method and system is proposed for adjusting the flow rate of charge material in such a process. According to the invention, a respective set of plural valve settings is stored for each batch, each valve setting of a set being associated to a different stage in the discharge of the batch. The method and system are configured to discharge a given batch so that, at each stage in the discharge of the given batch, the flow control valve operates at a constant valve opening according to the valve setting associated to that stage and so that an actual average flow rate at which charge material is discharged is determined for that stage. Further according to the invention, the method and system are configured to correct the plural valve settings offline and in function of the actual average flow rate determined for the associated stage. | 12-22-2011 |

| 20120243969 | COAL FLOW DISTRIBUTION CONTROLLERS FOR COAL PULVERIZERS - A solid particle flow distribution controller includes an extension skirt configured to be mounted to a discharge skirt at a division between an upstream solid particle conveyance pipe and a plurality of downstream pipes. The extension skirt includes a plurality of circumferential segments. Each segment is movably mounted to the discharge skirt for movement in an upstream and downstream direction with respect to the discharge skirt. The segments of the extension skirt are configured and adapted for motion in the upstream and downstream direction independent of one another to extend upstream of the discharge skirt as needed to improve solid particle distribution among the downstream pipes. | 09-27-2012 |

| 20150118012 | WAFER ENTRY PORT WITH GAS CONCENTRATION ATTENUATORS - The embodiments herein relate to methods and apparatus for inserting a substrate into a processing chamber. While many of the disclosed embodiments are described in relation to insertion of a semiconductor substrate into an anneal chamber with minimal introduction of oxygen, the implementations are not so limited. The disclosed embodiments are useful in many different situations where a relatively flat object is inserted through a channel into a processing volume, where it is desired that a particular gas concentration in the processing volume remain low. The disclosed embodiments use multiple cavities to serially attenuate the concentration of oxygen as the substrate moves into the processing volume of the anneal chamber. In some cases, a relatively high flow of gas originating from the anneal chamber is used. Further, a relatively low transfer speed may be used to transport the substrate into and out of the anneal chamber. | 04-30-2015 |
