 is produced in the firebox by exhausting the steam coming from the cylinders out the chimney. The Lemprex exhaust will deliver improved draughting capacity over traditional exhaust systems. However development is only at an early stage. Some work was undertaken in Brazil and is expected to be completed in Argentina by Ing. Shaun McMahon.
