Scotch, scotch marine, or shell boilers have the fire-tubes and combustion chamber housed within the same shell. Firebox boilers have a water-jacketed firebox and employ at most three passes of combustion gases. Most modern fire-tube boilers have cylindrical outer shells with a small round combustion chamber located inside the bottom of the shell.

C. Boiler Water Level: On every steam boiler there is a small glass tube located on the outside of the boiler. Commonly called a "Gauge Glass", this tube indicates the precise level of the water in the boiler. In order for the steam boiler to function properly, the correct water level must be maintained within the boiler vessel.
Our engineering team designed a threepass fire tube steam boiler with a capacity of 5000 kg of steam per hour and a operating pressure of 10 bar. The Figure below equations shows a standard three pass fire tube steam boiler system used as a template for our engineering team's design.
Two primary boiler types, the firetube boiler and the watertube boiler, are essentially opposite in design. The firetube boiler passes combustion gas inside a series of tubes surrounded by water in a vessel to produce steam, while a watertube instead sends water through a series of tubes surrounded by combustion gas used to transfer heat energy
Boiler design is the process of designing boilers used for various purposes. The main function of a boiler is to heat water for steam generation. Steam produced can be used for a variety of purposes including space heating , sterilization, drying, humidification and power generation. The temperature or condition of steam required for these applications is different, so how to design a boiler
