Tips for Specifying Fire Tube Boilers
Packaged boilers are commonly fire tube boilers as they are easily transportable since the boiler tubes are contained within the Shell. Fire Tube Boilers are best suited for lower pressure and flow applications since the steam/water pressure is contained on the shell side (as opposed to a water tube boiler where the steam/water pressure is contained on the tube side).
Fire tube boilers can operate on a number of fuels, the most common being gas fired fire tube boilers or oil fired fire tube boilers.
When designing and purchasing fire tube steam boilers, purchasers will need to consider the following, which is usually expressed in the form of a technical data sheet:
1. Exact composition of Coal to be used
2. Efficiency and emission requirements
3. Design and selection of the fuel handling and combustion system (en-trained bed, fixed bed or fluidized bed)
4. Safety
5. Materials of construction
6. Design code (ASME BPVC, EN, JIS…etc)
7. Operating and design pressure and temperatures
8. Pressure, temperature and flow measurement instrumentation
9. Control Valves, Manual Valves and Pressure relief valves
10. Feed water preheating
11. Water quality and composition
12. Spatial requirements and environmental considerations
13. Available Water Quality
