Boiler (power generation) - Wikipedia
A boiler or steam generator is a device used to create steam by applying heat energy to water. Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 A voluminous coal fire was lit on a grate beneath the slightly dished pan
