Boiler - Wikipedia

Pot boiler or Haycock boiler/Haystack boiler: A primitive "kettle" where a fire heats a partially filled water container from below. 18th century Haycock boilers generally produced and stored large volumes of very low-pressure steam, often hardly above that of the atmosphere. These could burn wood or most often, coal.

Scaling in boilers - Lenntech

Boiler scale is caused by impurities being precipitated out of the water directly on heat transfer surfaces or by suspended matter in water settling out on the metal and becoming hard and adherent. Evaporation in a boiler causes impurities to concentrate. This interferes with heat transfers and may cause hot spots. Leading to local overheating.

Minimize Boiler Blowdown. Having too many total dissolved solids (TDS’s) in the boiler water can cause scale and reduce boiler efficiency. Therefore, it is necessary to maintain the solids below certain limits. As TDS concentration increases, it becomes more likely that the dissolved solids will precipate out of the water and form scale.
