Selection of Papers by L.D. Porta – Volume 2

Compounding and Water Treatment

The Argentinean engineer Livio Danre Porta (1922 – 2003) remains an unsung hero in the long history of steam development. Following in the footsteps of Chapelon, he rebuilt numerous locomotives in Argentina and elsewhere, and designed several revolutionary locomotives, both large and small. Like Chapelon, none of his designs were built and most of his rebuilds have been lost to the scrap merchants. He has however left a rich legacy in the form of several hundred technical papers covering a wide range of subjects and written in a variety of languages. A few of his papers were published in conference proceedings and some were left in typed format, but the majority were left as hand-written manuscripts.  Some were written for specific purposes such as his “A1 Paper” that was written in the
hope of influencing the design of Tornado, and his “Compounding” paper that was written to try to influence David Wardale’s design of the 5AT. Others were written for the purpose of ensuring that the development of steam locomotives would continue into the 21st century.  The papers that are left to us are mostly of poor quality, having been photocopied many times and circulated amongst the “modern steam aficionados”. These can be hard to read, and most contain “Porta-isms” (grammatical errors) that require interpretation.

Chris Newman has transcribed 19 of Porta’s English-language papers and is publishing them in three volumes through the auspices of the Advanced Steam Traction Trust and with the permission of the Porta Family Foundation. This second volume offers three Porta’s papers relating to: the principles of compounding; his A1 proposal (also a compound) and water treatment, the last of which should be of great interest to the 21st century steam community.

This volume titled “Compounding and Water Treatment” includes just three papers as follows:

  • Fundamentals of the Porta Compounding System
  • A Proposal for the Tornado Project
  • Steam Locomotive Boiler Water Treatment including Notes on a 2003 discussion with Dave Wardale regarding Porta’s water treatment paper.

Covering 200 black in white A4 pages, this volume is expected to be priced in the region of £25.
