Examples of vertical boilers are: simple vertical boiler and Cochran boiler. (ii). Horizontal Boilers: When the axis of the shell in a boiler is found horizontal than it is called a horizontal boiler. Lancashire boiler, Babcock and Wilcox boiler and locomotive boilers are examples of horizontal boilers. 5.

The Feedtank and Feedwater Conditioning | Spirax Sarco
The boiler undergoes thermal shock when cold water is introduced to the hot surfaces of the boiler wall and its tubes. Hotter feedwater means a lower temperature difference and less risk of thermal shock. To maintain the designed output. The lower the boiler feedwater temperature, the more heat is required in the boiler to produce steam.

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 psi) but, at pressures above this, it is more usual to speak of a steam generator.
