Fireside Boiler Cleaning

The fireside of a heating unit is where the burner flame is present, creating hot flue gases that travel through an enclosed chamber and flue passages (boiler tubes, water tubes, etc.) as it makes its way to the breeching and out of the chimney. The heat of the gases is transferred through the typically steel walls of the enclosed chamber and flue passages by thermal conduction, heating the water on the waterside of the unit, and ultimately creating steam. This process can lead to soot build-up, which are fine black particle deposits chiefly composed of carbon, produced by the incomplete combustion of fuel. Soot build-up in the fireside causes reduced boiler efficiency, corrosion failure of steel, reduced heat transfer rates to the waterside of the unit, draft loss, excessive fan power consumption, and fire hazards. As little as an 1/8” of soot build-up can decrease boiler efficiency and heat transfer by as much 8% due to its powerful insulating power that will lead to high fuel consumption, which is typically the largest operational expense within a heating system.

Fireside Boiler Cleaning Maintenance Service

Scotch Marine Fire/Water Tube Style Boilers

Shut-off electrical, fuel supplies, and burner assemblies as necessary. Disconnect and open all fireside access doors and ports. Punch and vacuum all steel boiler tubes, brush the front and rear smoke boxes, chamber, and tube sheets free of soot build-up using nylon tip brushes and a high-powered truck mounted vacuum. Inspect the boiler tubes, steel, interior refractories, and door assemblies for deficiencies. Close and secure all fireside access doors, ports, and replace fireside gaskets as necessary to properly secure the fireside of the unit and prevent the leakage of harmful flue gases into the boiler room.

Cast Iron Sectional Boilers

Shut-off electrical, fuel supplies, and burner assemblies as necessary. Disconnect and open all side cover plates. Brush and vacuum all sections and interior chamber free of soot build-up from the exposed cover plates using nylon tip brushes and a high-powered truck mounted vacuum. Inspect the visible area of each cast iron section, chamber, refractories, and cover plates for deficiencies. Reinstall all cover plates and replace fireside gaskets as necessary to properly secure the fireside of the unit and prevent the leakage of harmful flue gases into the boiler room.

Modular/Atmospheric Boilers

Shut-off electrical and fuel supplies as necessary. Disconnect and remove the draft hood, top jacket panel, and flue cover. Brush and vacuum all flue passages free of soot build-up using a wire brush and high-powered truck mounted vacuum. Remove holding wire clip at burner ribbon orifice, Lift rear of burner ribbon and remove burner ribbon from assembly, clean burner ribbons as necessary using a soft flue brush. Inspect the chamber, interior draft hood, insulation, and burner ribbons. Reinstall cleaned burner ribbons, flue cover, top jacket panel, draft hood, and replace fireside gaskets as necessary to properly secure the fireside of the unit and prevent the leakage of harmful flue gases into the boiler room.
