Firetube Boilers - Two Pass Wet-Back (SG) - Performance

The SG Firetube Boilers are only available in a two pass design. The two pass design has a more balanced heat transfer from the tube to the water than a three pass design. The optimized heat transfer lessens the thermal stresses on the structure and helps mitigate cracking or deformation.

Firetube Boilers - Two Pass Dry Back (FT) - Performance

The FT Firetube Boilers are our economical direct fired, two pass dry back boilers. The burner's flame travels down the firetube and enters the inversion chamber. The exhaust gases then travel from the inversion chamber through the combustion tubes and exit the boiler through the exhaust stack.

Boilers and Type of Boilers - Forbes Marshall

Depending upon the layout of tubes boilers can be two pass or three pass boilers. Two pass boilers: In two pass the combustion gases travels two times in the boiler. Combustion gases should be cooled before entering the reversal chamber. Excess temperature causes overheating and cracking of the tube. The heat transfer rate is maximum at the first pass, this rate decreases with the increasing passes. Three pass boilers:

Firetube Boilers - The National Board of Boiler and

Scotch boilers may be two-pass, three-pass, or four-pass depending upon the arrangement of baffles and tubes. Four passes are generally recognized as the practical maximum when balancing economic heat transfer and condensation induced corrosion. Each pass through the boiler transfers heat from the products of combustion to the water in the boiler.

3 pass firetube boiler design

Generally speaking, a boiler with more passes provides more opportunities for hot gasses to transfer heat to the water in a boiler and operate more efficiently, however, boiler efficiency is highly affected by tube design, and not simply the number of passes. It is possible for a 3-pass boiler with a tube design (such as XID boiler tubes) that

The water tube boiler diagram is shown below, and these two drums are associated via two tubes such as downcomer and riser. At first, the water is supplied into the steam type drum with the help of a water pump. Whenever the fuel is burned, then hot gases will be generated that are permitted to supply in the shell part of the boiler.
