Fulton RB Horizontal Steam / Hot Water Boiler

Built/Certified in Accordance in to ASME Boiler and Pressure Vessel Code

The RB series boiler is a wet-back reverse flame horizontal boiler. With large furnace volume, large furnace surface area, the furnace exit temperature is reduced via enhanced radiation and convection, and front gas chamber condition is much better than the regular reverse fire boilers.
It has a large number of fire tubes and a large tube total cross-sectional area. It’s water level probe directly immerses into pressure vessel, which avoids false water level, and increases operating security.
The RB series boiler is a compact size boiler which can fit in the container.


The concept was to design and manufacture the best horizontal reverse flame, three pass, wet back steam/hot-water boiler on the market

Robust with Performance

Fulton’s RB Boiler is a high quality horizontal firetube boiler. With more than 10,000 boilers sold in more than 40 countries, the RB has proven itself time and again for customers around the world. All RB boilers are factory packaged with and integrated boiler, burner, and control package configured to provide the industry’s lowest cost of ownership.


The design team, with considerable combined experience in the design and manufacture of steam boilers in the UK and Europe, set out to incorporate good custom and practice into modern design and construction methods. The Fulton design criteria of high operating efficiency and a boiler that will last for many years, has meant that the RBC has many unique features and performance characteristics which are shown on the cutaway illustration. The RBC bears favourable comparison with all similar boilers, wherever in the world they are made. There has been no compromise in the brief to make a highly efficient, safe, reliable, long lasting and easily maintainable boiler in the Fulton tradition.

Reliability at Its Core

The concept behind the RB boiler was to design and construct a range of horizontal steam boilers that incorporates all the current code requirements with the Fulton reputation for quality and longevity. The specification is superior to and exceeds the minimum construction standards of BS2790:1992 Class 1. There are many unique design features that make it one of the most efficient and durable boilers available. The boiler is fitted with matched Nu-way oil, gas or dual fuel burner as standard with other burners as options

Versatile Performance

The RB range is suitable to meet the process steam demands throughout industry. The Simplex Technical Sales Support team are able to give system and application advice for the RB and the full range of Fulton boilers and ancillary equipment.
