| 1. | William Wilkinson of Wigan patented the exhaust steam reheating system about 1881.
|
| 2. | The boiler was fed using " Friedmann " exhaust steam injectors.
|
| 3. | Exhaust steam was re-condensed instead of escaping and fed back to the boiler.
|
| 4. | The front cylinders were fed with the exhaust steam of the high-pressure cylinders.
|
| 5. | A feedwater heater is placed around each cylinder where the exhaust steam exits.
|
| 6. | This heated the exhaust steam to avoid it condensing into a visible white plume.
|
| 7. | It removes heat from the engine exhaust steam to condense it back into water.
|
| 8. | Two small chimneys were fitted to each tender to discharge the exhaust steam from these cylinders.
|
| 9. | Exhaust steam from the cylinders of each engine unit was led to the smokebox by separate pipes.
|
| 10. | The tender was capable of condensing of exhaust steam per hour in maximum operating temperatures of between.
