CSR released today a new White Paper that outlines the thermo-mechanical behaviors associated with steam locomotive fireboxes (including the firebox sheets, tube sheets, tubes and staybolts). This technical paper was originally written by modern steam engineer Livio Dante Porta in 1984 / 1985 during his work on the ACE 3000 modern steam project in the U.S. As such, the White Paper also includes information specific to tests undertaken with C&O steam locomotive 614 and issues it had with staybolt leakage.
This White Paper has been digitzed by CSR from the original hand drawn and hand written piece, with slight editing for clarity. Be sure to read it, and all of the other CSR papers, on the CSR White Paper Program page.
