Lempor ejector

From Wikipedia, the free encyclopedia

The Lempor ejector is a steam ejector developed by noted Argentinian locomotive engineer Livio Dante Porta. In a steam locomotive, draft is produced in the firebox by exhausting the steam coming from the cylinders out the chimney. The LemPor exhaust delivers a 100% improvement in draughting capacity over traditional exhaust systems. The name is a combination of the names of Jean Lemaître and Porta.
