As well as carrying coal to heat the boiler, they needed fresh water to boil to create steam. All that weight made them inefficient and reduced their range. Though early steamship designers had enjoyed modest success with their seawater boilers, James Weir's evaporator was the first truly reliable device of its kind.

Wastewater Evaporator: What Is It? How Does It Work? Types

Wastewater evaporators that use a compressor need to have an outside steam source such as a boiler or heater in the feed tank. Mist Eliminator: The mist pad or eliminator removes contaminants from the process that may be in the form of oil or other possible substances.

Boiler water treatment - Lenntech

Evaporators using steam to drive the evaporation process require less heat transfer area than hot oil-heated evaporators. However, if the target material undergoing the evaporation process is not heat sensitive, hot oil is often the better option, since the oil's temperature can be higher than steam temperatures, reducing the required amount of overall heat transfer area for the system.

Boiler feedwater heaters are designed to improve boiler efficiency by extracting heat from streams such as boiler water blowdown and turbine extraction or excess exhaust steam. Feedwater heaters are generally classified as low-pressure (ahead of the deaerator), high-pressure (after the deaerator), or deaerating heaters.
