Admitting that I’m not infallible and occasionally fumble my way through challenges is part of the journey. However, the silver lining lies in sharing these experiences, or as I like to call them, “screw ups,” to offer genuine advice based on firsthand mishaps. So, let’s dive into a few bioheat lessons that might spare you some headaches and swiftly usher you into the realm of low-cost, automated, and eco-friendly heat, with a nod to Heizomat.
The Big Bolt Blockage with Heizomat Insight
Fuel quality discussions are commonplace in the biomass community, emphasizing the need for perfectly sized fuel. In Canada, where abundant low-cost waste wood is available, the challenge lies in the demand and supply chain for ‘biomass quality’ fuel. Our choice of Heizomat boilers for Canada proved beneficial, boasting a robust feed system designed to handle oversized fuel, simplifying the burning of readily available waste wood.
In a daring move, I decided to test the system with a truckload of ‘tub grinder’ chips, and red flags appeared when a hydraulic cylinder fell out during unloading. The unexpected hurdle came in the form of a 5″ long, ½” thick bolt jamming the ash auger. Though it didn’t shut down the Heizomat boiler, clearing the jam took some time. Lesson learned: bolts as fuel spell trouble, especially for boilers not built to handle them.
Clinkergate and Heizomat’s Response
Beyond bolts, the recycled chip introduced other contaminants, resulting in ash sticking to fire bricks and forming stubborn clinkers. Despite having a chain grate biomass boiler tailored for clinkers, their sheer number and size overwhelmed our modest Heizomat boiler. Cleaning the fire chamber, initially a bi-seasonal task, became a weekly struggle, involving Thor’s hammer and an underpaid student.
The key takeaway here is to steer clear of contaminants, especially acidic ones, as they can be corrosive and shorten a Heizomat boiler’s lifespan. Always consult with your Heizomat boiler supplier about your proposed fuel before attempting to burn it.
The Chimney Fire Challenge for Heizomat Boilers
Addressing the perennial question about handling green or wet fuel, we tested it by burning wet fir chips for three weeks using a Heizomat boiler. Predictably, the wet fuel resulted in lower heat output and an inconsistent fire. Upon returning to dry fuel, an unexpected chimney fire occurred due to creosote buildup from increased moisture and lower flue gas temperatures.
Wet fuel not only reduces heat output but can lead to chimney fires, shorten fire brick lifespan in Heizomat boilers, and increase maintenance. Drying wet chips is a straightforward process—protect them from weather, allow airflow, and in 2-4 months, they’ll be dry enough for burning (20-25% moisture content).
The Bunker Jam: A Heizomat Perspective
In an unrelated incident to the recycled chip, a lumber yard’s fuel introduced a sizable hardwood knot that stubbornly jammed the system of our Heizomat boiler. While our smaller Heizomat boiler with a 6″ feed auger struggled, larger augers or chain conveyors would have handled it with ease. Lesson learned: when it comes to oversized or challenging fuel in Heizomat boilers, bigger is indeed better.
The Shutdown Curse and Heizomat’s Precautions
This one comes from a customer who shut down their Heizomat boiler in spring without performing the recommended pre-shutdown maintenance. The consequence? Summer humidity turned leftover ash into a sticky mess, jamming the ash auger of their Heizomat boiler and turning a simple task into an extensive half-day project. A reminder that a little maintenance goes a long way.
The Secret to a Forgettable Boiler, Heizomat-Style
Achieving a hands-off biomass boiler requires careful planning, especially when opting for Heizomat. While I cherish the moments when I can forget about my Heizomat boiler entirely, it demands some initial effort. I’ve penned down ‘5 Tips for a Truly Hands-Off Biomass Boiler,’ which you might find helpful.
