[ Construction ]

Construction
and materials

Two-pass fire-tube design with reverse flow – flue gases make two complete turns through the gas ducts, passing through the cooled bottom of the furnace and the smoke tubes with turbulators. This ensures deep cooling and maximum heat extraction.

  • Cylindrical symmetry of the body and tube sheets – ideal distribution of mechanical and thermal loads, radically increasing fatigue durability
  • Smoke tubes with spiral turbulators – create gas flow vortices, increasing heat extraction and efficiency
  • Gas-tight design with forced draft operation – eliminates air ingress, ensuring stable combustion
  • Optimized water volume – high thermal inertia acts as a built-in damper, smoothing out temperature and pressure spikes in the system
  • Resistance to cyclic loads – guarantees uninterrupted operation even under intensive 24/7 use.
  • Body made of boiler steel P265GH (EN 10028) (increased strength, impact toughness, corrosion resistance)
  • Welded joints are performed by robotic complexes with subsequent non-destructive testing (NDT, radiography)
  • Hydraulic tests – at a pressure 1.5 times higher than the operating pressure
  • Manufacturing tolerances and control are 30% stricter than industry standards.

Fuel flexibility

Core operates on natural gas, diesel fuel, heavy fuel oil, furnace oil, and waste oil. The ability to equip with combined burners for quick fuel switching provides protection against fuel price fluctuations and ensures energy independence.

Service & warranty

Core boilers come with a lifetime manufacturer's warranty on the heat exchanger and main load-bearing elements, provided that installation, operation, and water-chemical regime rules are followed.

Each boiler is accompanied by a complete set of technical documentation: passport, installation and operation manual, non-destructive testing protocols, hydraulic testing protocols, compliance certificates according to PED/EN conformity requirements.
