TFB – Oil/Gas ( 20.000 – 30.000 kg/h)

  • Steam generation capacity: 320 kg/h - 18000 kg/h
  • Operating Pressure: 0.5-20 Bar
  • Fuel Type: Natural Gas, LPG, Diesel, Fuel Oil

Prominent Features

• Scotch type, 3-pass design with double furnace provides low flue gas temperatures and high efficiency.

• Design, production and commissioning can be carried out with economizer and steam superheater unit upon request.

• It has high steam generation capacity thanks to the design with double furnace. In addition, it provides fuel saving thanks to its wide steam generation modulation with its double burner design.

• The heating surfaces are clear and true values. The total area of heat transfer in the boiler is given clearly and accurately.

• Provides safe and stable operation thanks to high quality safety equipment.

• Thanks to PLC controlled touch screen control panel, quick technical support can be obtained from anywhere in the world with easy operation and remote access from mobile devices.

• Shipped with long-lasting insulation that minimizes heat losses.

• The boiler is manufactured as corrugated and firebox corrugated according to operating pressure values. The strength of the boiler and its resistance to thermal stresses are thus increased.

• Production in accordance with EN12953 and PED2014 / 68 CE directive

• Welding control of our boilers is carried out with ULTRASONIC test within the scope specified in EN 12953.

• After the boiler tubes are fixed to the boiler mirror with roller expander, welding process is applied. The risk of cracks in welds due to thermal stresses occurring in boiler tubes is eliminated.

• Our welded productions are carried out by certified welders according to approved WPS and WPQRs. Automatic submerged arc welding, MIG-MAG and SMAW welding techniques are applied in accordance with the norms.

• They are manufactured by using high quality, certified boiler sheet and seamless boiler tubes in accordance with standard requirements.
