A steam generating unit generally is not a self contained unit and allows the steam by-product (water) to escape. A Boiler is generally a sealed system that recirculates the condensed water back to the heating chamber for re-use.
Granville T. Woods invented the Steam Boiler Furnace
In order for a high temperature boiler or steam engine to produce superheated water, or steam?
circulation ration of boiler is defined as ratio of Mass of Steam/water mixture to steam generation.
"What the inside of steam boiler?" Would you like to know: with no water and steam, construction, under steam conditions, high loads, high TDS, Low pressure.
Inventor Granville Woods received his first patent on January 3, 1884 for a steam boiler furnace.
steam turbine cold start up list:
Water or steam? It makes a difference.
500 MW Boiler is sub-critical Boiler which generates steam at pressure lower than the critical pressure ie below 221.2 kg/sqcm. where as the 660 MW boiler is super critical boiler which operates steam pressure above critical pressure.
boiler use many type of working fluids like water, Mercury, liquid sodium, etc., but steam generator works only with water as working fluid. hence all steam generator are boilers but all boilers are not steam generators...
In Cogeneration Plant : The generated steam in boiler is used for both power generation & process heating, thereby reducing the condenstion losses compared to thermal power plant. In combined cycle first is gas turbine , rather than wasting the flue gas from gas turbine, we are sending it into boiler and again generating steam for running steam turbine. Both the ways we are increasing the thermal efficiency of the plant

boiler are working on same principal but automatic and manual boiler has difference that manual boiler working at single element loop and automatic boiler work at three element loop.single loop means when fuel increase mean load increase on boiler by adjusting fuel operator has to adjust steam drum level manualy , while automatic means when load increas, fuel increase steam drum level adjust automaticaly by watching fuel consumption.
Use of water in a refinery is makeup for boiler feed. The chief uses of steam are for stripping, steam distillation, and vacuum distillation. The steam comes in contact with the products in these operations, and generally the steam condensate is so highly contaminated that it cannot be reused for boiler feed or for other purposes. Steam is also used for process heating, for pumping, and, in some refineries, for generating electric power
metal + steam = boiler

The steam drum separated the steam from the water and stream mixture in the boiler drum.
