Steam locomotives can transport loads on highly efficient railway systems, using raw solid biofuel directly while requiring few resources to build and maintain.
We have re-invented the locomotive boiler for the 21st century.
Our technology eliminates the sparks and smoke that traditional boilers emit when fed solid biofuel.
Two key principles underpin our design:
No heat is removed until combustion is complete.
Fast moving water is heated inside small robust tubes.
Our technology overcomes the challenges faced by conventional boilers, where a large volume of high pressure water surrounds a fire in a rectangular box with flat surfaces.
The conventional boiler’s water-walled firebox quenches combustion, generating smoke, which coats the heat transfer surfaces leading to frequent cleaning while producing heavy local particulate pollution.
