• HRSG-FT fire-tube waste heat steam boilers are designed to produce saturated or superheated steam in order to meet heat demands for various purposes, using as the heat source process waste gases or biogas / syngas obtained from gasifiers and similar equipment.

• They are frequently preferred for industrial heating processes.

• With filtration systems selected to suit the chemical composition of the waste gas, the emission limit values set by the regulations are readily achieved.

• Depending on the waste heat source, they can be designed and manufactured as 2-pass or 3-pass units.

• Thanks to optional systems that allow unattended operation, such as “Automatic Ash Removal System” and  “Automatic Tube Cleaning System“, efficient, stable and fully automatically controlled operation is achieved.

• The flue gas filter selected to suit the chemical properties of the waste gas  (“Multicyclone”, “Cyclone”, “Wet Flue Gas Filter”,  “Bag Filter”) keeps emission values below the permitted limits.

• On request, design, manufacture and commissioning can be carried out together with an economizer and a steam superheating unit.

• Heating surfaces are net, actual values. The total of the areas inside the boiler where heat transfer takes place is stated net and correctly.

• High-quality safety equipment provides safe and stable operation.

• Thanks to the PLC-controlled touchscreen control panel, operation is straightforward, and remote access from mobile devices makes fast technical support available anywhere in the world.

• Manufactured in accordance with EN12953 and the PED2014/68 CE directive.

• Weld inspection on our boilers is carried out within the scope specified in EN 12953.

• Boiler tubes are secured to the tube sheet with a tube expander and are then welded. This removes the risk of cracks in the welds caused by thermal stresses in the boiler tubes.

• Our welded fabrication is carried out by our certified welders in accordance with approved WPS and WPQR. In manufacture, automatic submerged arc welding, MIG-MAG and SMAW are applied in accordance with the standards.

• It is manufactured from high-quality certified boiler plate and seamless drawn steel boiler tube, in accordance with the requirements of the standards.
