Patent number: 8360137Abstract: A regenerative heat exchanger is disclosed and described for gas streams that perform heat exchange between one another using a buffer that is continuously immersed in the gas streams. The buffer is cleanable by a pivotable blowing arm that uses spray nozzles to clean the buffer. The blowing arm has an axis that is positioned parallel to the flow direction of the gas streams across the buffer and allows for the use of two blowing arms which extend in a mirror image opposite to one another. The spray nozzles each distribute compressed air and/or pressurized water.Type: GrantFiled: October 3, 2008Date of Patent: January 29, 2013Assignee: Balcke-Dürr GmbHInventor: Manfred Flender

Publication number: 20110126460Abstract: A rotating heat regenerator is used to recover heat from the syngas at it exits the reactor vessel of a waste or biomass gasifier. In some embodiments, three or more streams are passed through the heat exchanger. One stream is the dirty syngas, which heats the rotating material. A second stream is a cold stream that is heated as it passes through the material. A third stream is a cleaning stream, which serves to remove particulates that are collected on the rotating material as the dirty syngas passes through it. This apparatus can also be used as an auto-heat exchanger, or it can exchange heat between separate flows in the gasifier process. The apparatus can also be used to reduce the heating requirement for the thermal residence chamber (TRC) used downstream from the gasification system.Type: ApplicationFiled: May 25, 2010Publication date: June 2, 2011Applicant: InEnTec LLCInventors: Leslie Bromberg, Daniel R.

Patent number: 7918268Abstract: A heat exchanger (10) comprises a first sheet (12), a second sheet (14) and an additional sheet (30). The first and second sheets (12,14) are wound around an axis (X), each sheet (12,14) has hot and cold edges at the hot and cold ends (16,18) respectively of the heat exchanger (10). The hot and cold edges of the first sheet (12) are joined to the hot and cold edges of the second sheet (14). The end (12A) of the first sheet (12) is joined to the second sheet (30) by an axially extending join (28) at a position spaced from the end (14A) of the second sheet (14). The end (30A) of the additional sheet (30) is joined to the end (14A) of the second sheet (14) by an axially extending join (28). The additional sheet (30) is thicker and wider than the first and second sheets (12,14) such that at least one of the hot and cold edges (30C,30D) of the additional sheet (30) extend beyond the hot and cold edges of the first and second sheets (12,14).Type: GrantFiled: August 28, 2009Date of Patent: April 5, 2011Assignee: Rolls-Royce plcInventor: James I Oswald

Publication number: 20110073023Abstract: A thermally efficiency regenerative air preheater 250 extracts more thermal energy from the flue gas exiting a solid fuel fired furnace 26 by employing an alkaline injection system 276. This mitigates acid fouling by selectively injecting different sized alkaline particles 275 into the air preheater 250. Small particles provide nucleation sites for condensation and neutralization of acid vapors. Large particles are injected to contact and selectively adhere to the heat exchange elements 542 and neutralize liquid acid that condenses there. When the deposit accumulation exceeds a threshold, the apparatus generates and utilizes a higher relative percentage of large particles. Similarly, a larger relative percentage of small particles are used in other cases. Mitigation of the fouling conditions permits the redesign of the air preheater 250 to achieve the transfer of more heat from the flue resulting in a lower flue gas outlet temperature without excessive fouling.Type: ApplicationFiled: March 16, 2010Publication date: March 31, 2011Inventors: James W.
