There are many of considerations to factor when determining the best boiler for ones steam generation needs like operating pressure, steam pounds/hour output, demand fluctuation, general application requirements and total cost of ownership, etc.
Two primary boiler types, the fire tube boiler plus the water tube boiler, are essentially opposite in design. The fire tube boiler passes combustion gas in a very group of tubes in the middle of water in a very vessel to produce steam, while a water tube instead sends water by way of a group of tubes surrounded by combustion gas helpful to transfer heat energy and produce steam.

| Fire Tube VS Water Tube |
Here are a few key differences between the fire tube boiler and water tube boiler:
Water tube Boilers:
- higher operating pressures- higher temperature output
- safe, dependable design
- precise load fluctuation handling
- superheated steam generation
- fast heat recovery
- better reject
Fire tube Boilers:
- compact construction- efficient, straight tube design
- lower total cost of ownership
- easier access and maintenance
- good load surge handling @ pressure
- simple operation
