Product Description

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.  The dry back design refers to the use of refractory at the back of the boiler in the inversion chamber.    

The FT Firetube Boilers are specifically designed to minimize the thermal stress on the boiler not only at high pressures, but at low pressures as well.  Cutting-edge technologies are used to construct the fire tube boilers that help reduce the thermal stresses that occur when operating the boiler.  In addition, the firetube boilers are designed with a large thermal inertia, allowing for fluctuations in steam demand and are ideal for continuous 24/7/365 applications.

The FT has the opportunity to be supplied with a variety of forced draft burners provided by some of the world’s leading burner manufactures.  This allows us to utilize a variety of fuels, meet stringent emissions requirements, and even allow our customers the opportunity to select the burner of their choice.

The FT-PA is our high efficiency option of the FT Firetube Boiler.  The FT-PA is constructed in a horizontal orientation and is supplied with a combustion air preheater at the burner side of the heater.

The FT-ECO is our feedwater preheater option of the FT Firetube Boiler.  The feedwater preheater utilizes an economizer to preheat the water entering the steam generator.  This enables the customer to obtain optimum performance of the generator by supplying the necessary feedwater temperatures to the Firetube Boiler.

The BONO FT, FT-PA, and FT-ECO Firetube Boilers are fabricated by our partner in Italy, BONO Energia, and are available designed/constructed to various local code requirements around the world.  The most common codes are ASME with National Board registration for the United States, CRN for Canada, and CE/PED/TUV/DIN for Europe.  Additional code requirements may be met if necessary.

Package and containerized systems are available for both the FT, FT-PA, and FT-ECO Firetube Boilers. These package systems can be customized to meet each of our customers’ needs, including but not limited to: control panel, feedwater pumps, feedwater tanks, deaerator, water treatment, and ancillary components. These auxiliary components are typically fabricated in the USA for USA/Canada installations.  

Firetube Boilers In General

Firetube boilers are a form of large water content boilers used to provide customers with steam as a heat transfer media.  Typically, the quality of steam provided by these units are is much higher than forced circulation steam generators.  The higher quality of steam mitigates the use of steam separators or steam accumulators.
