Vertical cyclone type and horizontal burner type are the two most commonly used incinerators on the ship.
The setup is similar to a horizontally fired boiler with a burner arrangement horizontal to the incinerator combustion chamber axis. The ash and noncombustible material remaining at the end of the operation has to be cleared out manually.
In this type, the burner is mounted on the top and the waste to be incinerated in introduced into the combustion chamber from the top. A rotating arm device is provided to improve combustion and remove ash and non-combustibles from the surface.
