Firetube vs Watertube boilers: a comparison

 

Firetube Boiler Design & Operation

Firetube boilers operate by sending combustion/flue gas through a series of straight tubes surrounded by hot water stored in the same vessel. Often identified by the number of passes used (such as a 3-pass or 4-pass firetube boiler), this refers to the number of times combustion gas flows the length of the pressure vessel as it transfers heat to the water.


firetube boiler design


A wet-back firetube boiler uses a water cooled turn around zone (end closure). A dry-back design relies on fire brick or refractory lining to prevent the end closure from overheating.

Firetube boilers cost typically less up front than watertube boilers, and offer lower operating costs when compared to a similarly sized watertube boiler. They are also easier to maintain due to better fireside access and their efficient straight tube design.

Firetube boilers can handle up to 3000 HP / 450 PSI with a single burner. Though smaller and more compact in design than watertube boilers of similar size, they can take longer to reach operating temperatures from a cold start but can handle steam demand fluctuations well once running.

 

Trust The Boiler Experts at IB&M

With proven performance, unmatched size range and reliability under the most demanding conditions, it's obvious why Johnston  has become our most requested firetube boiler product lines. Another key benefit is maintenance cost savings. While some manufacturers have proprietary equipment and parts with exclusive vendor service contracts, Johnston's boiler construction provides for greater service and vendor flexibility, often at a much lower price. While the price of a boiler may look favorable, it pays to fully understand the total cost of ownership when maintenance and parts are factored in. IB&M can consult with you and help you through the buying process to make sure you have all the information required to decide the right equipment solution.

 

In addition to an extensive in-stock boiler inventory, we offer firetube boiler customization to meet any specification. Firetube boilers can be shipped individually, on a packaged skid, or as complete "boiler in a box" solution. And as as a fully licensed General Contractor with divisions dedicated to every aspect of the boiler room inside and out, we are able to provide system design and engineering, concrete work, electrical services, process piping, and more to provide a total steam plant solution.

JOHNSTON BOILER COMPANY

IB&M is proud to represent the world’s largest Scotch marine firetube boiler manufacturer, Johnston Boiler Company. Johnston’s built-to-last boilers have the highest efficiencies and best warranties in the industry. In fact, Johnston is the only boiler manufacturer who carries a 15-year warranty on their product. In addition to the quality and dependability, the conservative boiler design provides excellent fuel to steam efficiency resulting in the best life cycle costs in the industry. Johnston Boiler Company offers 2,3 & 4 pass boiler designs with varying HP levels to meet your specific steam generation needs.
509 Series
The Johnston 509 Series offers an efficient 4-pass boiler (50-1600 HP) configuration which maximizes heat transfer, while at the same time eliminating tube sheet stresses and costly maintenance repairs that are common with dry backed designs, as well as a 3-pass boiler (1800-2500 HP) with its high steam and water storage areas, high efficiencies, rugged construction, and its ability to keep up with wide load demands.
XID Scotch Marine Boiler
The Johnston 509 Series offers an efficient 4-pass boiler (50-1600 HP) configuration which maximizes heat transfer, while at the same time eliminating tube sheet stresses and costly maintenance repairs that are common with dry backed designs, as well as a 3-pass boiler (1800-2500 HP) with its high steam and water storage areas, high efficiencies, rugged construction, and its ability to keep up with wide load demands.
309 Series
The Johnston 309 Series 3-pass boiler is specifically designed to match your burner with our boiler. The 309 Series can be manufactured up to a 750 HP steam boiler, and features large steam and water storage areas, high efficiencies, and the ability to meet wide load demands. The 3-pass package consists of the pressure vessel, base assembly, and boiler trim which maximizes heat transfer while minimizing the use of refractory.
WHR Series
Johnston's Waste Heat Recovery boiler (WHR) units recover heat from gas turbines, gasoline or diesel engines, and other equipment that produce exhaust gases about 600°F. This recovered energy may be used to generate steam or to heat water or other heating fluids or plant and process requirements.
