KBB – Oil/Gas (300 – 4000 kg/h)

  • Steam generation capacity: 300 kg/h - 3000 kg/h
  • Operating Pressure: 0.5-20 Bar
  • Fuel Type: Natural Gas, LPG, Diesel, Fuel Oil

Prominent Features

• Thanks to the design of the two pass, reverse flame type, 2 pass fast steam generation, high quality steam production is achieved in a short time and with high efficiency.

• Wet-frame (water-cooled) structure of the front and rear covers eliminates the damage caused by refractory deformations.

• It has more heat transfer surface area than its counterparts. Thus, the thermal load per square meter is lower and has a longer life.

• Thanks to its wet frame structure, heat losses are minimized, boiler efficiency is increased and fuel consumption is reduced.

• Wet frames provide extra heat transfer surface and extend boiler life.

• Due to its compact structure, it occupies minimum space in facilities.

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

• 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 and according to EN 473 and ASNT SNT-TC-1A by a level 2 certified specialist.

• After the boiler tubes are fixed to the boiler mirror with roller expander, welding process is applied. Thus, 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.
