Lempor exhaust system

The modern Lempor ejector consists of four main components:

1. The blast pipe or Tuyere made up of four nozzles which have convergent/divergent sections; 2. The mixing chamber; 3. The diffuser; 4. The Kordina which is so designed that each 'puff' of exhaust steam creates a vacuum in the other cylinder.
