Design study of coal-fired cored brick regenerative heat exchangers
Abstract
A design study was conducted for cored ceramic brick regenerative heat exchangers for use as air preheaters in coal-fired open cycle magnetohydrodynamic (MHD) power generation systems. Air preheater designs for a 2000 megawatt electrical MHD power plant were analyzed with a computer code that simulated the transient cyclic behavior of the heat exchangers, used local instantaneous ceramic and gas properties, and contained a Nusselt number correlation which included rough surface and entrance effects. The design problem was so formulated that only the reheat inlet velocity and ceramic bed length must be determined to complete design.
