The bottom line: Your boiler provides the steam and heat you need to keep things running smoothly, whether it’s throughout campus or within a commercial sector. But are you taking advantage of the wasted heat and fuel gases it also produces? Go beyond simply reducing your carbon footprint; make a case for the circular economy movement with the help of Simoneau’s heat recovery/waste gas solutions.

It’s inevitable, when energy is produced, there’s always a portion of it that is wasted by released heat. The same goes when your boiler produces steam from the combustion process. With a heat recovery system, you can funnel wasted heat/fuel gases and repurpose it for steam generation purposes or heat transfer. Essentially, you’re being cost efficient and making good use of what would be otherwise released into the air through pipes and chimneys.

A spin on the expression “Waste not, want not.”

Because every unit is different, all heat recovery projects require a thorough understanding of a boiler system’s gas makeup and combustion process. Thanks to our extensive experience in the boiler industry, we’ve come up throughout the years with a variety of complex and ingenious ways at Simoneau to funnel wasted heat and fuel gases back into your boiler so you can produce more precious energy…Energy that would’ve remained untapped if not for the recovery process.


Flows of flue gas for steam generation

What constitutes the complexity of a heat recovery system? Maintaining heat quality in tandem with another energy source that funnels the wasted heat while meeting your buildings’ temperature requirements. Indeed, no easy feat. Those sources can include duct burners, electrical turbines, motors, waste gas, biomass, digester gas (biogas) or even a second generator that pushes recovered heat through flue gases directly into the boiler.

More importantly, a reliable heat recovery boiler system needs to ensure that the flue gases funnelled to the boiler are adequately heated so that the gas remains dry and contains little moisture, in order to avoid possible corrosion. Additionally, also in an effort to avoid corrosion, the gas mustn’t contain high levels of Sulphur.


A cut above the rest, never a cut and paste project

Building a heat recovery system requires highly technical skills in boiler design; the same type of engineering skill set that is continuously honed, developed and mastered at Simoneau. As opposed to traditional boiler design (flame, gas, combustion), a heat recovery system is completely dependent on the makeup of the gas (percentage of humidity, Sulphur, reaction of the digester gas) and on the speed and quality of the fans used to push it through the system. Every gas/heat source varies from project to project.


Custom designs backed by years of field experience

One of Simoneau’s first heat recovery projects was a large-scale unit. The boilers were customized to meet specific steam requirements and the unit itself is equipped with a furnace that captures all the steam. Connected at the tail end of the system is a large convection section that warms the water up as it goes into the furnace section.

Yes, heat recovery may be different with every project, with varying degrees of complexity and utilizing diverse equipment, but the common benefit it provides, whether you manage university, hospital or municipal buildings, is a sustainable solution for heat or energy redistribution that fits within the circular economy approach. It’s more than just about trying to reduce your gas emissions.

When you’re dealing with Simoneau, you’re working with boiler experts that have the key knowledge to come up with the precise calculations and complex design to produce the most efficient heat recovery system for your boiler.
