    Isn't reversosmosis just forcing water through the semipermeable membrane against osmotic pressure?

    The preheater to the boiler stripper is nothing more than heat integration. Some waste heat from somewhere else on the ship is, I'm presuming, captured via a fluid and transferred there as a means to reduce the heating requirements of the boiler. Similar techniques are used in plants to offset utility costs. Here, probably done for safety reasons.

    I've seen an attempt to use this same technology to harvest hydrogen from water then inject it into the induction system of petrol/diesel engines which supposedly resulted in lower emissions and an increase in fuel economy however it's unclear if the end result was worth investing in as the gains were relatively small and therefore required that one do a lot of mileage for it to pay for itself. I believe the company was called 'CGON systems' and they were based in SW of England.

    The only reference I could think of in respect to "Clinker" is how when a patient uses a bed pan and makes a solid bowel movement they call it a "Clinker" due to the sides of a stainless bed pan. Honestly they kind of look like a form of excrement.

    So "klinker" is a blacksmithing and heating term for the glassy slag left over while burning coal, it's a hard slag inclusion independent from the ash that needs to be broken and cleared to prevent it from blocking teh airflow. Most coal burning devices have a "klinker breaker" to, obviously, break the klinker into pieces so it can fall through the grate.
