Jean Lemaître was a mechanical engineer from the Nord Belge Railway, who developed a Steam locomotive exhaust system
.
The Lemaître Exhaust
featured 5 nozzles in a circular pattern exhausting up a large-diameter stack, with a variable area nozzle exhausting up the center, and improved efficiency by about 10%.
The design was later improved by Livio Dante Porta
, who created the Lempor
and Lemprex
, named after a combination of their two names.

Lempor ejector
The Lempor ejector is a Steam locomotive exhaust system developed by noted Argentine locomotive engineer Livio Dante Porta. In a steam locomotive, draft is produced in the firebox by exhausting the steam coming from the cylinders out of the chimney, or also by a blower. The LemPor exhaust delivers...
