firetube boiler design

The Scotch Marine Boiler is a firetube boiler, in that hot flue gases pass through tubes set within a tank of water. The general layout is that of a squat horizontal cylinder. One or more large cylindrical furnaces are in the lower part of the boiler shell. Above this is a large number of small-diameter fire-tubes.

User rating: 5/5 • The boiler manufacturers tried to prevent this thermal shock through controls and flow design with in the boiler. 3 National Board Training Thermally Induced stress cycling (Thermal Shock) in Firetube Boilers G Halley NB Bulletin Winter 1998.

These design changes have resulted in a marked improvement in heat transfer efficiency of the fire-tube boilers. Another outcome from this is that the overall footprint (boiler size) of the fire-tube boilers will be smaller in comparison to the water-tube boilers only in the lower capacities up to about 4,000,000 BTU/hr.

Understanding the operational design differences. Firetube boilers are available in either dryback or wetback design. They are identified by the type of reversal (turnaround) chamber, or posterior portion of the combustion chamber, through which flue gasses travel through the furnace to second-pass tubes to heat water within the boiler.

Firetube boilers can be constructed in different configurations. The most common designs are: Horizontal Return Tubular (HRT) – this is an old and very simple design which is still being manufactured. The boiler consists of a shell, a tube sheet on each end of the shell, and tubes connecting the two tube sheets.

Jun 13, 2013· Watertube boilers are safer by design and generally considered to last much longer than the firetube boiler. They are available in much larger sizes and recover faster than firetube boilers, can handle pressures up to 5000 psig, and have the ability to reach very high temperatures with the use of …

As one of the oldest and most simple designs for … 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
