KVARTAL solid fuel boilers from Ukraine are used for heating industrial and domestic spaces: private homes, administrative buildings, warehouses, workshops, factories, farm buildings, and others, with areas ranging from 100 sq. m to 1000 sq. m. They operate on coal, wood, sawdust, peat, briquettes, and other fuels. High-quality, certified sheet steel and seamless pipes are used for the boiler body and heat exchanger, while advanced technologies are implemented. A three-chamber flue system ensures high efficiency—up to 93%—more complete combustion control, and reduced emissions. The first chamber, the firebox, has a large volume and maximizes the combustion time of a single fuel load and reduces maintenance time. The second chamber maximizes heat transfer from the combustion products thanks to its large heat exchange area. The third, the ash chamber, is also used for heat exchange and for collecting ash and combustion residues. Thermal insulation is provided by non-flammable, environmentally friendly mineral wool. Combustion is controlled by optimally supplying air through special ducts into the combustion zone. Kvartal boilers feature a large inlet with a door to accommodate a significant amount of fuel for long-term combustion, ensuring reliable and highly efficient operation.
